Secondary Valve with Siphon Tube (Optional) Tank straps not shown. 6 Cylinder Tank Assembly The TANK Fire Suppression cylinder assembly (p/n 87-300001-001) uses a mild steel cylinder, conforming to 4BW250 DOT & 4BWM-17 TC specifications, and a nickel-plated brass valve with pressure indicator gauge. Each valve includes a Schrader valve for connection to the primary actuator hose (for primary cylinders) or the supervisory pressure switch (optional for secondary cylinders). Each cylinder assembly is factory-filled with TANK liquid fire suppressant and pressurized to 200 psig (1379 kPA) at 70°F (21°C). Each cylinder supports up to 5 nozzles for a total of 20 flow points. Figure 3 - Cylinder Tank Details The pressure of a cylinder will vary with the ambient temperature, as detailed in Table 1. The gauge indicator (shown in Figure 3) should be in the acceptable ‘green’ range for a cylinder that is properly pressurized and within the listed operating temperature range. For a cylinder at the lowest listed operating temperature of 32°F (0°C), the pressure gauge should read approximately 175 psig (the lower end of the green range). For a cylinder at the highest listed operating temperature of 130°F (54.4°C), the pressure gauge should read approximately 225 psig (the upper end of the green range). NOTE: The agent itself may be stored down to -20°F (not operational system temperature). Table 1 - Cylinder Temperature Vs Pressure 1. Pressure Gauge 2. Primary Schrader Valve 3. Secondary Schrader Valve 4. Discharge Outlet A. Tank to Actuator Distance = 23-1/4” B. Tank Diameter = 10” 7 Cylinder Tank and Actuator Bracket Each cylinder assembly is secured to a factory-installed cylinder bracket in the cabinet (p/n TFS- UCTANKBRACKET). The cylinder is secured to the cylinder bracket via three (3) stainless steel straps. The cylinder bracket also includes a platform for securing a primary actuator kit or secondary valve actuator during shipping and maintenance procedures. Figure 4 - Cylinder Tank and Actuator Bracket Discharge Adapter The discharge adapter (p/n WK-283952-000) is used to connect the TANK Fire Suppression cylinder valve outlet to the agent distribution pipe network. The 1/2-inch NPT internal thread of the discharge adapter outlet is connected to the supply line via an elbow and adapter. The discharge adapter uses an O-ring (p/n WK-108019-000) at the valve port to eliminate leaks during discharge. Figure 5 - Discharge Adapter 8 Nozzles The Overlapping Female Nozzle(s) (p/n OL-F) are used for plenum, duct, and dedicated appliance coverage (e.g., salamanders, upright broilers, chain broilers, and appliance with upright obstructions). The nozzles include a cap (p/n 3074-1-1). The cap prevents contamination from entering the pipe network and is designed to pop-off upon system discharge, allowing the agent to flow to the protected hazard area. Refer to “Duct and Plenum Protection” on page 15. Figure 6 - Fire System Nozzle Primary Actuator Kit (PAK) The Primary Actuator Kit (PAK) (p/n 87-300030-001) is installed on each primary cylinder assembly to pneumatically open the cylinder valve and provide actuation pressure for up to three secondary valve actu- ators. A vent limiting orifice is present to allow easier resetting of SVA pistons during inspections. The PAK consists of a pneumatic actuator, 24V DC solenoid valve, solenoid strainer (recommended by the manufacturer), check valve, primary actuator hose, and associated fittings. When activated, through automatic or manual system actuation, the control panel sends a momentary 24V DC release signal. The solenoid strainer will filter out debris from entering the system. The PAK solenoid will open, allowing pressure from the primary cylinder to pass through the solenoid and check valve. The pressure flows into the primary actuator (actuating the primary cylinder), and into the interconnected sec- ondary valve actuators (actuating the secondary cylinders). The primary actuator has a 1/8” NPT inlet port for connection to the primary system cylinder, and a 1/8” NPT outlet port for connection to the secondary cylinder actuation line or actuation line vent limiting orifice for single cylinder system. The primary actuator includes a piston with a spring-loaded locking pin which locks the piston in the discharge position, ensuring complete discharge of the cylinder contents. When testing/inspecting, if a component fails inspection, replace the PAK assembly. Figure 7 - Primary Actuator Kit NOTE: The primary supervisory pressure switch is standard on primary tanks. Secondary supervisory pressure switches are optional on secondary tanks. Nozzle P/N: OL-F Previously P/N 3070-3/8H-10-SS 1. Schrader Service Valve 2. Check Valve 3. Solenoid Valve 4.

Vent Limiting Orifice 9 Secondary Valve Actuator (SVA) and Hose A Secondary Valve Actuator (SVA) (p/n 87-120042-001) is installed on each secondary cylinder assembly to pneumatically open the cylinder valve(s). The SVA has 1/8” NPT inlet and outlet ports for connection to the system actuation line via the SVA hose. All secondary hoses require a 1” minimum bend radius. The SVA includes a spring-loaded locking pin that locks the actuator piston in the discharge position, ensuring complete discharge of the cylinder contents. Figure 8 - Secondary Valve Actuator Supervisory Pressure Switch The primary and (optional) secondary supervisory pressure switch (p/n 87-300040-001) are preset to alarm at a cylinder pressure of ~10% below the lowest operating system pressure of 175 psig (pressure at the lowest listed operation temperature of 32°F). The supervisory pressure switch uses a diaphragm sensor to detect pressure changes. At the predetermined set point, the unit actuates a SPDT snap-acting switch, converting a pressure signal into an electrical signal. The supervisory pressure switch can be used on primary and/or secondary cylinders. For primary cylinders, the pressure switch is mounted on the primary actuator kit. For secondary cylinders, the pressure switch is mounted on the Schrader fitting installed on the cylinder valve. Apply Leak Lock joint sealing compound on the sealing surface of the Schrader valve when connecting/replacing the supervisory pressure switch. Figure 9 - Supervisory Pressure Switch 1.

Schrader Valve 10 Gas Shut-Off Valves Electric gas shut-off valves are used to shut down the flow of fuel gas to the kitchen appliances upon actuation of the TANK Fire Suppression system. An energized solenoid is used to hold the gas valve in the open position. The solenoid closes the valve when de-energized via the output relay of the control panel. The gas valves are available in 120V AC and 24V DC, ranging from 3/4” to 3” pipe sizes (Table 2). Electric Remote Manual Release An electrically operated manual release that is listed must be used with the TANK Fire Suppression extinguishing system. The electric remote manual release is used to actuate the TANK Fire Suppression extinguishing system manually and must be properly located and supervised in accordance with NFPA 17A and NFPA 96. Firestat (Heat) Detector The Firestat (Fenwal Detect-a-Fire) is a listed electric thermal detector available in a variety of temperature settings and used to actuate the TANK Fire Suppression extinguishing system automatically. When a Firestat senses a temperature higher than its setpoint, the Firestat contacts will close and energize the TANK Fire Suppression system via the control panel.

All primary components and piping are factory-installed. Systems may be comprised of single or multiple cylinders depending on the size and configuration of the protected hazards. Cylinders can be piped independently, or manifolded. On two-cylinder systems, the cylinders will be in a manifold configuration. Refer to “Agent Distribution Piping” on page 32 for a two-cylinder system example. On three-cylinder systems, two cylinders will be in a manifold configuration and one independent. On four-cylinder systems, there will be two separate manifolds. In a fire condition or upon manual actuation, the solenoid valve is opened, allowing pressure from the primary cylinder to flow to the primary and secondary cylinder valve actuators, opening the cylinder valves and discharging liquid fire suppressant to the protected hazard areas. Figure 11 - Cylinder Assemblies Cylinder Tanks Figure 12 - Dual Cylinder Mounted in Cabinet Cylinders are typically factory-installed, pressurized, and may be located anywhere within the hood end cabinet. Additional cylinders may be field installed, as needed, in the additional hood end or wall mount cabinet. Figure 12 shows a dual cylinder system mounted to the right of the hood control unit. Each cylinder assembly is secured to a factory-installed cylinder bracket in the hood end cabinet. The cylinder is secured to the cylinder bracket via three (3) stainless steel straps. WARNING!

Max of 5 nozzles per TANK for duct and plenum coverage only. Each duct and plenum nozzle protection is 4 flow points. Plenum Protection The nozzle(s) (page 8), are used to protect plenum areas in both single bank and V-bank plenum configu- rations. The nozzle will protect up to a 4' wide x 10' long plenum section. For larger plenum areas, addi- tional nozzles are added as required, with each nozzle protecting no more than a 4' wide by 10' long plenum section. Nozzles may be installed pointing in the same direction, and/or at opposite ends of the plenum, pointing toward each other. The nozzles must not be installed back-to-back when protecting ple- num areas. When positioned at the end of the plenum, nozzles must be installed from 0 to 6" into plenum. If the riser is not centered on the plenum, the plenum nozzle is placed on the side of the plenum closest to the riser. The nozzle locations for plenum protection are shown in Figure 17 and Figure 18. Figure 17 - Single Bank Filter Plenum 16 Figure 18 - Dual V-Bank Filter Plenum Duct Protection The nozzle(s) (page 8) is used for the protection of exhaust ductwork and can protect any duct cross- section type (e.g. round, square, or rectangular). A sufficient quantity of nozzles must be provided to ensure that no single nozzle coverage exceeds 75" in perimeter. A single nozzle will protect a duct up to 75” perimeter (22” nominal diameter) and unlimited length. Two nozzles are required for protection of 75-150” perimeter and unlimited length. A minimum of 3 nozzles is required for protection of ducts exceeding 150" perimeter (36” nominal diameter) and unlimited length. When using multiple nozzles (modular protection), the coverage area for each nozzle must not exceed 75" perimeter. Figure 19 - Nozzle Duct Protection 1. Duct 2. Hood 3. Single Nozzle 4. Dual Nozzle 17 Nozzles must be installed from 0" to 6" into the protected area of the duct. When more than one nozzle is required (modular protection), each nozzle must be located at the center of its protected module area. Additional nozzles are not required for changes in direction*. Duct obstructions and common ductwork must be protected in accordance with this manual, NFPA 17A and NFPA 96. The nozzle location and aim for duct protection are shown in Figure 20 and Figure 21. *When a change in direction occurs less than 6" from the duct entrance, the nozzle must be aimed as shown in Figure 20 and Figure 21.

It is recommended that the exhaust fan remain on at the time of discharge to aid in the removal of smoke, gases, and other airborne materials from the hazard area in the event of a fire. If the Authority Having Jurisdiction (AHJ) requires that the damper closes in the event of a fire system discharge, the system designer shall provide for protection downstream of the damper in compliance with NFPA 96, local codes, and/or as approved by the AHJ. Electrostatic Precipitators (ESP) An Electrostatic Precipitator (ESP) is designed to remove smoke and other airborne contaminants from the air flowing through the exhaust ductwork as a means of pollution control. Exhaust ductwork using ESPs requires Overlapping Male nozzle(s) (p/n OL-M [previously 3070-3/8HH-10-SS]) upstream, before the ESP. Distribution piping to the nozzles must not interfere with the function of the ESP unit. A Pollution Control Unit (PCU) and/or Electrostatic Precipitator (ESP) covered with this fire system can utilize up to 12 nozzles per tank. 1. Nozzle 2. Vertical Duct Centerline (CL) 3. Aim Point 4.

The Hazard Zone consists of the cook- ing surface of each appliance underneath each hood. For dedicated and overlapping nozzle information, refer to “Nozzles” on page 8. Overlapping appliance coverage allows a given area under the hood, defined as the hazard zone, to be protected by overlapping nozzles. Nozzles are evenly spaced at the same height and alignment (front-to- back) relative to the hazard zone. Dedicated appliance protection utilizes a nozzle, or nozzles, for protection of an individual appliance. Overlapping, dedicated appliance, plenum, and duct protection may be incorporated in a single pipe network on the TANK Fire Suppression extinguishing system, as long as the number of nozzles per tank does not exceed five. The following sections detail the different nozzle coverage and placement parameters for overlapping and dedicated nozzle appliance protection methodologies. Double row coverage is allowed for TANK. Overlapping Appliance Protection A single hazard zone utilizing overlapping coverage is 30” deep, by the total length of the hazard zone for the protected appliances. The cooking surface of all appliances protected by overlapping nozzles must be located within the defined hazard zone area. Cooking appliances eligible for overlapping protection are outlined in Table 3 on page 20. The lowest and highest cooking surface will determine the height of the fire suppression nozzles. All overlapping nozzles must be mounted at the same height in a single hazard zone. For applications where overlapping protection cannot be used, such as an upright boiler, dedicated appli- ance protection must be used. Figure 22 - Overlapping Protection Option 20 Appliance Coverage Table 3 illustrates the maximum permitted hazard zone dimensions of each appliance that can be pro- tected within a single overlapping zone. It is important to note that the hazard zone (area requiring protec- tion) is different than the total appliance size. Notes: 1. All dimensions shown are based on overlapping protection. 2. All dimensions and areas shown reference the hazard zone of the appliance, which is typically smaller than the outside dimensions of the appliance itself. 3. For multi-vat fryers, no single fryer module (vat & drip board) can exceed the above limitations. Nozzle height(s) for fryers should be taken from the fryer’s minimum level indicator. 4. Protection for tilt skillets and braising pans are to be based on the coverage parameters provided for fryer protection. Tilt skillets should be placed at the back of the hazard zone. Tilt skillet coverage must not interfere with the edge of the nozzle discharge pattern. 5. All appliance hazard surfaces must be located within the hazard zone. 6. Smaller appliances can be positioned anywhere in the zone (e.g., moved left, right, forward, or backward, provided the cooking hazard does not extend beyond the perimeter of the zone). 7. When the depth of the appliance exceeds maximum cooking hazard dimensions, a second row of nozzle coverage should be added. 8. Deep Fat/Industrial Fryer/Tilt Skillets over 14” wide and up to 34” max depth will be overlapping with 4 nozzles per tank, 30” max spacing. Max oil capacity: 24.75 gallons. Refer to Table 4 on page 21. Figure 22 illustrates the placement of nozzles for TANK Fire Suppression overlapping protection. Appliances denoted with an (*), or if there is an obstruction as defined on Table 6 on page 21, dedicated coverage will be required. Refer to page 24, page 25, and page 29 for details.

Max oil capacity: 24.75 gallons. Nozzle height(s) for fryers should be taken from the fryer’s minimum level indicator. * Henny Penny fryer models 690, 691, and 692 are allowed with standard 30” max nozzle spacing as long as the nozzle flow pattern is not obstructed by the lid while in the fully open position. A nozzle is required on both sides of the lid. • Shelves or protrusions from appliances measuring 6” or less are not considered shelves, standard overlapping coverage applies. Refer to Table 3 on page 20. • Shelves or obstructions greater than 6” and up to 12” require 4 nozzles per tank, 36” max nozzle spac- ing. • Shelves exactly at 12” depth require 35” distance from nozzle tip to cooking surface. Shelves less than 12” may use nozzle distance from cooking surface of 35” to 50”, every effort should be taken to mini- mize nozzle spray pattern obstruction with the shelf. Refer to “Appliance with Shelf” on page 25 for more information.

Exceptions are noted below. All overlapping nozzles must be spaced no more than 12” from each end of the appliance, and located at the centerline of the 30” hazard zone (front to back), at the same height, and aimed straight down. The nozzle height must be 35” to 50” above the appliance cooking surface, except for woks, where the height is measured 3 inches below the top rim of the wok. The nozzles must be positioned along the total hazard zone length to allow protection of each appliance in the hazard zone. Exceptions to standard overlapping protection: • Large/Industrial fryers over 14” wide, 4 nozzles at 30” max nozzle spacing per tank. • Woks larger than 24 inch diameter, 4 nozzles at 30” max spacing per tank. • Appliance with shelves, 4 nozzles at 36” max spacing per tank. • Solid Fuel Appliances, 3 nozzles at 24” max spacing per tank. Refer to “Coverage Exceptions” on page 21 for more information. Overlapping Coverage - Group Protection Overlapping protection provides coverage for a continuous hazard zone, with all nozzles at consistent position (i.e., zone centerline), spacing, and height. When there is an area within a hazard zone for which continuous overlapping coverage is not applicable, the overlapping protection zone may be ended, and a new zone started for the new group of appliances. Examples where continuous protection may be interrupted include a counter, storage or prep area, appliance not requiring protection (e.g., enclosed oven) or an appliance requiring dedicated appliance coverage. The examples on page 23 provide details of group overlapping protection for interrupted zones. This section illustrates the methodology for defining when a new hazard zone is required, as described above. For appliance specific overlapping coverage parameters (e.g., nozzle spacing and height requirements), refer to page 24 through page 31. 23 NOTE: Overlapping nozzle spacing and height requirements are based on the appliances protected for each individual zone. Nozzles must always be located at the start and end of each zone, no more than 12” from the end of the hazard zone (edge of 1st/last cooking appliance surface). Refer to “Overlapping Appliance Protection” on page 19. Zones cannot overlap. NOTE: All hazard surfaces in a zone must be within 35”-50” of the nozzles in that zone. Group Protection Example 1 – Appliance line separated by unprotected space. End nozzles must be located 12” or less (horizontally) from the end of the hazard zone. Standard overlapping nozzles must be spaced no further than the maximum allowed interval 36” on center. Refer to “Coverage Exceptions” on page 21 for more details on coverage exceptions.

Unlike appliances with an exposed flat cooking surface, these appliances have an internal cooking surface and only have a small opening in the face or end of the appliance. To cover the internal hazard posed by these appliances, an Overlapping Female (OL-F) nozzle must be placed at the opening and aimed at the opposite rear corner of the appliance. This nozzle must be branched off one of the nozzle drops and piped to the appliance opening. No more than 2 nozzles per drop. The drawing below illustrates how this should be accomplished. Should the cooking surface of the appliance exceed 1,050 in2, an additional nozzle will be required on the opposite of the appliance for added fire protection. Refer to Figure 25 for details. 1.

The supply line is defined as the run of all pipe and fittings from the tank outlet to the last branch line, including fittings at the start of all branch lines. All branch lines start at the outlet of the applicable supply line fitting and do not include the supply tee. A plenum branch is defined as the run of all pipe and fittings from the supply line tee outlet to the plenum nozzle(s). Refer to Figure 34 on page 33. A duct branch is defined as the run of all pipe and fittings from the supply line tee outlet to the duct noz- zle(s). Duct branch lines on risers greater than 75 inch perimeter can have a “tee” installed. Two separate duct branch lines are not required. Refer to Figure 34 on page 33. An overlapping nozzle appliance branch is defined as the run of all pipe and fittings from the supply line tee outlet to the nozzle. Refer to Figure 34 on page 33. A dedicated nozzle appliance branch is defined as the run of all pipe and fittings from the supply line tee outlet to the nozzle. Refer to Figure 34 on page 33. 33 Refer to “Cylinder Nozzle and Piping Parameters” on page 34 for supply line and branch piping limita- tions. Figure 34 - Distribution Piping 34 Cylinder Nozzle and Piping Parameters A single cylinder supports up to 5 nozzles, 20 flow points. Max supply line up to 42 feet to the first overlap- ping nozzle. A dual cylinder system supports up to 40 flow points and 10 nozzles. Dual cylinder systems can be piped in series or parallel. Max supply line up to 42 feet to the first overlapping nozzle. Notes: 1. One (1) tee allowed per appliance drop. 2. No more than two nozzles can be utilized for a single appliance drop. 3. Additional elbows are permitted on branch lines and horizontal supply piping, provided linear pipe length is reduced by corresponding equivalent length (1.3 ft per 90° elbow, 0.6 ft per 45° elbow). For example: a 3/8” steel elbow has an equivalent length of 1.3 ft. An appliance branch may use 4 elbows, provided the total linear pipe is reduced by 1.3 ft (e.g., from 5 ft to 3.7 ft). Additional pipe cannot be added in lieu of fittings, as pipe volume limits could be exceeded. 4. Maximum 6 ft vertical rise of supply line above cylinder outlet. 5. Minimum 7 ft. of supply line to first overlapping nozzle. 6. If hoods are piped to the same tank, the sum of piping between hoods plus distance to first overlapping nozzle should NOT exceed 42 feet. Nozzle Installation Distribution piping and nozzles are factory-installed. Verify that the nozzles and distribution network are installed in accordance with the design and installation parameters for all protected hazards, as set forth in this manual. NOTE: The TANK Fire Suppression extinguishing system design must be reviewed if any hazard changes have been made, including (but not limited to): appliance type, appliance sizes, appliance location, factory pre-piping or nozzles, plenum size or configuration, and duct size or configuration. 1. Ensure nozzles are securely installed. DO NOT OVERTIGHTEN. NOTE: Do not over-tighten or nozzles may be damaged. 2. Ensure all nozzle types, placement, and aim are in accordance with the limitations in this manual. Nozzles can be used to achieve proper aim on dedicated appliance protection nozzles only. 3. Refer to Figure 6 on page 8 for details on nozzle(s).

A listed manual reset relay is required to ensure manual reset prior to fuel being restored in accordance to NFPA17A. Gas valves (Figure 35) are designed to shut off the flow of gas to the kitchen appliances in the event of fire system activation. Electric gas shutoff valves must be installed with an upstream strainer to prevent debris from prohibiting gas valve function. New pipe, properly reamed and cleaned of metal burrs, should be used. Proper care is needed to ensure that the gas flow is in the same direction as indicated on the gas valve and strainer. Do not over-tighten pipe connections. Apply pipe dope to the male threads only. If necessary, install a drip leg in the gas line in accordance with the Authority Having Jurisdiction (AHJ). 120V AC gas valves 3/4” - 2” can be mounted with the solenoid in any position above horizontal. 120V AC gas valves 2-1/2” - 3” must be mounted with the solenoid vertical and upright. The pipe must be horizontal. All 24V DC gas valves must be mounted with the solenoid vertical and upright. The pipe must be horizontal. Proper clearance must be provided in order to service the strainers. A minimum of 4” clearance distance must be provided at the base of the strainer. Figure 35 - Electric Gas Valve A gas strainer is supplied with the unit and recommended to be installed.

NOTE: Make sure the fire system is deactivated and all controls are powered down before servicing the unit. Service should only be performed by trained personnel. 1. Locate faulty sensor in hood riser. Remove the hood filters to access from the hood plenum. 2. Determine the location of the sensor’s lead ends. This will either be on the top of the hood, in the junction box which has conduit routed to the riser, or in the electrical control package that is mounted on the hood (if it is a stand-alone hood). 3. Access the sensor’s lead ends and remove Wago connectors. Attach a fish tape (or pulling rope) to the lead ends. 4. Unscrew the sensor from the quick seal in hood plenum. Pull leads completely out, pulling the fish tape until exposed. 5. Attach replacement sensor to fish tape and pull back through conduit until lead ends are back in the original location. 6. Replace Wago connectors on the new sensor’s lead ends. 7. Twist new sensor counterclockwise, 2-1/2 turns to pre-tension wires. Thread sensor in riser quick seal (using Teflon tape on threads). 8. Replace hood filters. 9. Power up the system to test functionality. Figure 37 - Sensor Replacement 38 Fire Protection Manual Actuation Device The push/pull station (Figure 38) is a remote manual actuation device to activate the fire system. This remote man- ual actuation device (push/pull station) contains one set of normally open contacts and mounts to any standard sin- gle gang junction box. When the front button is pressed, the electrical connection to the fire system is completed, thus activating the fire system. The remote manual actuation device (push/pull station) should be mounted at a point of egress and positioned at a height determined by the Authority Having Jurisdiction (AHJ). This position is usually 10 to 20 feet from hood and 42 to 48 inches above the floor. Multiple remote manual actuation devices (push/pull stations) are acceptable to use in the fire system and are wired in parallel per the electrical schematic. The remote manual actuation device (push/pull station) is reset by twisting the push-button clockwise until the internal latch is released. The clear protective cover must be installed to protect the device from accidental activations. This cover is pro- vided as part of the manual actuation device. Refer to Table 9 for device part numbers and replacement parts. NOTE: When connecting the wires to the push/pull station, do not twist the wire ends together. Insert each wire on the opposite side of the screw. Figure 38 - Manual Activation Device Trouble Input Wiring Trouble contacts and supervision switches from each device may be connected to the optional trouble input of the building fire alarm panel to indicate a trouble condition.

Building Fire Alarm - Trouble Input Wiring 39 Fire Protection System Printed Circuit Board The fire protection system printed circuit board (PCBCORE) is a microprocessor-based controller that pro- vides all the necessary monitoring, timing, and supervision functions required for the reliable operation of the fire system. Under normal conditions, the “Fire System Activated” light is on. This indicates the system is armed and active. If a fault is detected anywhere in the system, an audible alarm will periodically sound, and the “Fire System Activated” light will flash a fault code to indicate the fault that was detected. The HMI, located on the hood or Electrical Control Package (ECP), will display the fault text to explain where the issue is located in the system. Refer to “CORE Board Faults” on page 54. NOTE: CORE Boards with software version 1.68 and prior will use one brief flash every 3-seconds to indicate there are no faults in the fire system. When viewing the CORE Board, if a series of flashes followed by a pause exists, there is a fault in the sys- tem. Count the number of flashes between the pauses and refer to “CORE Board Faults” on page 54. Any fault is extremely important and must be corrected and rectified immediately to ensure proper opera- tion of the fire system. The optional connections for building fire panels are located at AL1 and AL2 as dry contacts. For remote mounted Ansul Automans, use terminals AU1 and AU2. This will provide a dry contact connec- tion point to provide power for activating the Ansul Automan. NOTE: When a CORE board is connected to an ECPM03 board, if a fire condition happens, the “Last Fire Info” will be stored on the ECPM03 screen. “Last Fire Info” will be available on CASLINK as well.

As-built wiring diagrams are furnished with each control package from the factory and are either attached to the door of the unit or provided with the paperwork packet. Electrical wiring and connections must be made in accordance with local ordinances and the National Electric Code, ANSI/NFPA70. Verify the voltage and phase of the power supply, and the wire amperage capacity is in accordance with the unit’s nameplate. ATTENTION: LOW-VOLTAGE DC OR SIGNALING WIRE SHOULD BE ROUTED IN SEPARATE CONDUIT FROM ALL AC VOLTAGE SOURCES. 1. Always disconnect power before working on or near this equipment. Lock and tag the disconnect switch or breaker to prevent accidental power-up. 2.There are multiple electrical connections required for this control. 120V AC should be wired to terminals H1 and N1. If the hood is equipped with a separate light circuit, 120V AC should power this circuit per the as-built schematic. H1 and N1 should not be connected to a shunt trip breaker. 3. Verify that the power source is compatible with the requirements of your equipment. The system wiring sche- matic identifies the proper phase and voltage of the equipment. 4. Before connecting the control package to a power source, verify power source wiring is de-energized. 5. Secure the power cable to prevent contact with sharp objects. 6. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces, or chemi- cals. Solenoid cables must not come in contact with hood surfaces. 7.The supervised loop must be run through metallic conduit. Do not run wiring with high voltage wires. Verify all supervised loop wires are free from damage/stress. All supervised loop wires must be termi- nated in terminal blocks, junction boxes, and push-stations. 8. If the system contains additional firestats, they must be wired into the supervised loop. 9. If the control package is a wall-mount system, a duct mounted temperature sensor will need to be wired. The temperature sensor must be wired to terminal blocks, as indicated on the wiring schematic. 10. If the control package is a wall-mount system, the hood lights wiring will need to be wired to terminals “B” and “W.” Verify connections on wiring schematic. 11. Before powering up the system, make sure that the interior of the control package is free of loose debris or shipping materials. 12. If any original internal wire supplied with the system must be replaced, use type THHN wire or equivalent. 13. All field-supplied wire for the optional fire system release solenoid or firestat must be high temp wire rated for 842°F minimum (#441601C6.FE9 White and #441601C6.FE0 Black). 14. The battery must be plugged in at connector J1 on the electrical board (PCBCORE) after wiring is complete. 15. All gas appliances under the hood must shut down in the event of an AC power loss. All electric appliances will shut down on building power loss. 16. Use Belden #6320UL,18 Gauge, plenum-rated wire or similar, for the supervised loop that does not come in contact with the hood. Use Belden #88760 or similar for the fire system interlock network and CAT-5 for Mod- bus communications. 17. All exterior wiring connections to the PCU must be run inside liquid tight conduit. This includes the supervised loop and airflow switch wiring. IMPORTANT!: The battery backup for the fire protection system produces output power even when main power is disconnected from system. When performing major electrical service to the control, the battery backup must be disconnected then reconnected before commissioning. WARNING! Disconnect power before installing or servicing control. High voltage electrical input is needed for this equipment. A qualified electrician should perform this work. 43 Wire Ampacity Rating The load current rating and the over-current protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied. Refer to Table 10. Distance Limitations Wiring connections to remote fire protection system(s) must use shielded twisted pair wire. The maximum length of this connection is 1000 feet. Wire size is an important consideration when making the connections between the fire protection system control package and a gas valve. Refer to Table 11 for maximum wiring distance between the system and remote gas valve. Fire Alarm Contacts The fire protection system is equipped with optional normally open contacts (terminals AL1 and AL2) for building applications that connect to the premise Fire Alarm Control Panel (FACP). Refer to Figure 41 for wiring reference. During a fire condition, the contacts will close and trigger the premise FACP to initiate a general fire alarm.

This will allow the user the ability to assign different zones for independent activation. In order to set a fire group, you will need to set the CORE board DIP switches as shown in Table 12. Note: Every panel with matching fire group settings (DIP switches 6 and 7) will activate simultaneously in a fire condition. Figure 42 shows an example of different zones on separate fire groups, but still connected via the interlock network. In the example, when 2 Fire groups (01 and 02) are assigned on the CORE boards, and if a fire condition exists in any one group, it will NOT activate the other fire group. However, both are connected to the same interlock network. • Fire Group 01 CORE board DIP switch setting will be set to: Switch 6 Open and Switch 7 Open. • Fire Group 02 CORE board DIP switch setting will be set to: Switch 6 Closed and Switch 7 Open. Refer to “Typical DIP Switch Arrangement” on page 58 for setting multiple CORE controlled fire systems. Figure 42 - Fire Group Reference Table 12 - Fire Group DIP Switch Position 6 7 Fire Group Number Open Open 1 Closed Open 2 Open Closed 3 Closed Closed 4 45 Fire Protection System Supervised Loops The supervised loops are integral to proper operation and activation of the Fire Protection System. All systems have two supervised loops; each loop consists of two conductors, one positive and one negative. One loop is ded- icated to all sensors, while the other is dedicated to all manual actuation devices (push/pull stations). The super- vised loop connections are located at the front edge of the hoods for accessibility. Connections beyond the hood, like the connections at the manual actuation device, must be made with a plenum-rated wire. It is recommended to use a two-conductor Belden 6320UL, 18 AWG, wire, or similar for these connections. Refer to Figure 43 for super- vised loop details. The supervised loop must be run through metallic conduit. Do not run wiring with high voltage wires. Verify all supervised loop wires are free from damage/stress. All supervised loop wires must be terminated in terminal blocks, junction boxes, and push-stations. • Connections to the firestat will use two Wago connectors. One for an incoming loop and one for an outgoing loop. • Flexible metallic conduit is used to route the wiring that connects the firestat to the remote loop junction box. Secure conduit to hood hat channel when possible. Figure 43 - Supervised Loop Connections For connections on or above the hood, use Type MG or MGT wiring with Wago connectors. A Supervised Loop Connection kit is available to connect back to back or end to end hoods. This kit will come with the necessary hardware and wire.

Current International Mechanical Code (IMC) requires that the fire system be installed by the manufacturer (2018 IMC). CORE and EWC fire systems are available for the PCU. PCU fire systems use electric sensors set at 360°F to activate the fire system. Outdoor EWC Systems require a climate controlled utility cabinet to ensure that the fire system does not drop below 32°F and does not exceed 130°F. See below for more information about outdoor installations. It is highly recommended that the PCU fire system be interlocked to the corresponding hood fire system so that if the hood system activates, the PCU system activates. Reverse activation requirements are determined by local code or at the discretion of the Authority Having Jurisdiction, but are recommended for safety. In the event that the fire system is accidentally activated, all disposable filters must be replaced and the pre-filter cleaned. The water or chemical agent used in the fire system can cause the filters to fail prematurely. In the event that a fire occurs in the ductwork leading to the PCU or inside the PCU, the following must be completed. • The unit must be cleaned of all fire suppression chemicals and grease. • The filters must be replaced, this includes the pre-filter. • If an ESP module is present, the ESP cells must be removed, and cleaned in warm soapy water. Wash cells until all chemical residue is removed. ESP pre and post filters must be replaced. When re- installing cell(s), make sure to install with the airflow in the correct direction as indicated on the cell. • If any of the gasketing is damaged, replace the gasketing between modules and between the doors. • If any of the components that make-up the Pollution Control Unit are damaged by fire, then that component must be replaced and inspected by factory trained service personnel. Installation, commissioning, or resetting of the fire system must be done by a licensed fire system installer. Use the guidelines set forth by the appropriate fire system manual; PCU with CORE Fire Suppression System manual, Model TANK (Electric Wet Chemical) Extinguishing System, or other fire system manufacturer. For electric wet chemical fire systems for PCU, external piping that connects the PCU fire system nozzles to the fire system tanks is factory-installed using Grade L 1/2” copper tubing and pro-press fittings. If a remote (wall mount) EWC fire system is utilized, distribution piping shall be Grade L 1/2” copper tubing and pro-press fittings or 3/8” NPT Schedule 40 black iron, chrome-plated, or stainless-steel pipe and fittings. If distribution piping is exposed to an outdoor environment it must be Grade L 1/2” copper tubing and pro- press fittings or 3/8” NPT Schedule 40 stainless-steel pipe and fittings. 48 PCU Fire System Nozzles The Overlapping Male Nozzle(s) (p/n OL-M) are used to protect the PCU. The nozzles include a cap (p/n 3074-1-1). Refer to Figure 45. The cap prevents contamination from entering the pipe network and is designed to pop-off upon system discharge, allowing the fire system to flow to the protected hazard area. Figure 45 - Fire System Nozzle Table 15 provides details on PCU size, modules, and nozzle quantity per unit. Pollution Control Units (PCU) cov- ered by a TANK Fire System can utilize up to 12 nozzles per tank. PCU Fire System type “REFS” is covered by TANK.

The system can be activated automatically via an electric thermal detector or manually via a remote manual actuator. The extinguishing system is electrically operated via the PCBCORE control board. The system can be activated automatically via a Firestat or manually via a remote manual actuator. Since the TANK Fire Suppression extinguishing system is electrically operated, the applicable fire alarm control panel requires AC input power with a battery backup system. Reference the applicable control panel manual for wiring and compatibility. When one of the system’s Firestat(s) detectors senses a temperature hotter than its internal set-point (e.g., in the event of a hood fire), or when a remote manual actuation device (push/pull station) is pushed, an electric signal is sent to the tank-based fire protection release solenoid via the fire alarm control panel releasing circuit. The electric release solenoid is energized, allowing pressurization of the pneumatic actu- ator(s). The actuator’s plunger(s) will depress into the tank valve body, releasing agent to flow to the hood duct, plenum, and appliance nozzles. When the fire extinguishing system is activated, the applicable fire alarm control panel simultaneously shuts down all gas and electric appliances under the protected hood(s), shuts down make-up air and/or exhaust where applicable, and activates the building fire alarm where applicable. The electrically operated fire system requires a battery backup system. In the event of a loss of building electrical power, all gas and electric appliances under the hood must be electrically interlocked to shut off. This is achieved via a gas valve relay and/or a shunt trip breaker. The battery backup will automatically energize upon a loss of power. The battery backup will monitor the fire system circuit for up to 24 hours and be able to operate the fire system circuit for a minimum of 30 minutes. Once power is restored, the battery will automatically recharge. A means of manual reset is required for shut-off devices to ensure manual reset prior to fuel or power being restored in accordance with NFPA 17 and NFPA 96. The electric gas shut-off valve is used in con- junction with a UL/ULC listed manual reset relay, refer to “Gas Shut-Off Valves” on page 35. Appliance and electrical shut down is achieved via the applicable fire alarm control panel relay, in conjunc- tion with UL/ULC listed enclosed industrial control equipment or magnetic contactors of appropriate rating. These must be used in conjunction with a UL/ULC listed manual reset relay, refer to Figure 46. All wiring is to be in accordance with the applicable manufacturer’s instructions for the fire alarm control panel, gas shut-off valve, manual reset relay, and contractor supplied shut-off devices. All wiring must be in accor- dance to NFPA 70 and the Authority Having Jurisdiction (AHJ). The TANK Fire Suppression System is not required to be interlocked to a building’s fire alarm control panel to function. When a building fire alarm system is present, the fire alarm control panel may be connected such that the actuation of the TANK Fire Suppression extinguishing system also activates the fire alarm. Reference the applicable control panel manual for wiring and compatibility. Figure 46 - Reset Relay 50 Test Mode Overview The fire protection system has an integrated option for testing. When in test mode, the release solenoid is disabled and will prevent the fire extinguishing agent from spraying on the appliances. For testing purposes, this will allow the activation of the fire system, audible alarm, shunt trip breaker (if applicable), and shut down of appliances via gas valve reset relay. All additional PCBCORE controlled packages that are attached to the system must be in “Test” mode. This includes additional fire protection systems, Pollution Control Unit with CORE, and other hood-mounted CORE controlled protection systems. Please note that the appliances must be started before test mode is entered on any PCBCORE protection package for proper demonstration of this function. If the fire protection system is left in “Test” mode for more than 15 minutes, the appliances will shut down. This is to prevent cooking operations from occurring while the appliances and ventilation system are not protected. ATTENTION: All interlocked PCBCORE controlled packages must be placed into “Test” mode before cleaning the hood, Pollution Control Unit (PCU), or any other interlocked units. Reset Overview There are multiple actions required to reset the fire system. The following must be completed by a Certified Fire System Technician. 1. The duct firestat must be cooled below its internal set point. 2. The remote manual actuation device (push/pull station) must be reset by twisting the button clockwise until it resets. 3. Press the “Push To Reset Fire System” button. 4. Reset the pneumatic actuators (PAK, SVA), refer to “Re-arming System” on page 63. Note: The firestat must be cool, and the remote manual actuation device (push/pull station) must be reset for this button to work. The fire system must be re-commissioned per the manufacturer’s recommendations and guidelines by an authorized fire system distributor and/or authorized service agent. WARNING: In the event of an actual fire, further inspections are required after the fire has been extin- guished to verify the integrity of the hood, ductwork, fire sensors, fan, and fire suppression system has not been compromised. With approval from the Authority Having Jurisdiction (AHJ) or the Fire Depart- ment, proceed to restarting the fire system. Figure 47 - Fire System Reset 1. LED Indicator 2. Alarm Speaker 3.

During a power loss, the “Fire System Activated” light will flash 11 times between pauses indicating the power loss. The batteries must be replaced every 2 years, from the date of fire system commissioning. Part number PS-1270-F2, two are required. Although the batteries are hot-swappable, which means they can be replaced while there is input power to the control, for your safety, all sources of power must be removed from the control before replacing the batteries. To replace the batteries, unplug the battery cable from the J1 connector on the electrical board (PCBCORE). Then remove the retaining strap holding the batteries in place. Remove the batteries from the cabinet. Transfer the fuse and cable set from the old batteries to the new batteries being extremely careful to observe the RED and BLACK lead and terminal colors. Reinstall the batteries in the cabinet and reconnect the battery plug to J1. The batteries are lead-acid type and are recyclable; please dispose of the old batteries properly. During extended periods of inactivity where the fire protection system will be without AC power for more than 2 days, such as a shutdown or natural disaster, it is best to decommission the fire system by disconnecting the batteries. This will prevent any damage to the batteries through complete discharge. When the system becomes active again, commission the system by reconnecting the batteries and allow the batteries to charge for 48 hours. The TANK suppression system is supplied with 14-amp hours of backup battery capacity. Per NFPA 72 10.5.6.3, the system requires 1.66 amp hours of battery capacity. Power Supply Adjustment Figure 49 - Power Supply To properly charge the batteries, the power supply must be adjusted to output 27.5V DC. This can be checked with an accurate digital voltmeter placed across Terminals H1D and N1D. To adjust the output voltage, place a small flat-bladed screwdriver into the yellow dial. Turn the dial clockwise, this will increase the voltage. Important! The battery backup system requires that the batteries be changed every 2 years, from the date of fire system commissioning, maximum. Failure to do this will result in a void in product reliability and may cause severe damage to facility due to loss of fire protection. 52 Fire Protection System Firestat The Firestat (page 36) is a device installed in the riser of the hood, at the duct connection, that measures temperature. One sensor shall be installed in each exhaust riser. Secondary downstream detectors in the duct are not required except as outlined in the Non-Solid Fuel Appliances and Solid Fuel Appliances section. Sensors are not required above each appliance or in the hood grease plenum. The standard temperature setting is 360°F. Depending on heat produced by appliance, a higher rated temperature Firestat will be required. If a temperature higher than the setpoint is sensed, the Firestat contacts will close and energize the electrical control board. The fire system will activate. The supervised loop must be run through metallic conduit. Do not run wiring with high voltage wires. Verify all supervised loop wires are free from damage/stress. All supervised loop wires must be terminated in terminal blocks, junction boxes, and push-stations. The Firestat has 2 black wires and 2 white wires. These wires must be connected to the supervised loop. Use high- temperature wiring when installing Firestat components. Wago connectors (part number: 221-412) must be used. Multiple sensors are wired in parallel in the supervised loop. The Firestat may be installed on the opposite side of the quick seal for access in the duct. Non-Solid Fuel Appliances (Rated 450°F) Non-solid fuel appliances rated for 450°F will not require additional firestats, regardless of the configuration and length of ductwork. Non-Solid Fuel Appliances (Rated 600°F) Non-solid fuel appliances rated for 600°F will require downstream detection if the duct run contains any horizontal section over 25 feet in length. Downstream detection should be installed at the end of a horizontal section. Duct layouts that include less than 25 feet of horizontal ductwork will not require additional detection. Solid Fuel Appliances (Rated 700°F) Solid fuel appliances produce effluents that can accumulate inside the duct, especially in long horizontal duct runs. Sparks from solid fuel appliances can travel into the ductwork and create fires that occur beyond the point where the hood riser Firestat can detect them. Additional downstream Firestats ensure that these duct fires are detected and the fire system actuates. Solid fuel applications require 600°F rated Firestats, and SOLO filters. Exhaust fan(s) used with solid fuel appliances must use a steel wheel. In addition to the 600°F rated Firestat, located in the hood riser, a second Firestat is required at the duct discharge for solid fuel applications when the ductwork exceeds 10 feet in length or contains horizontal runs. Even if the entire duct run is inaccessible, this additional Firestat is still needed. Mounting a Firestat in the fan may be an option. On duct runs longer than 50 feet, a third Firestat will be required somewhere in the duct run, ideally at the end of a horizontal run, if present. Duct runs longer than 100 feet will require additional Firestats, contact your local sales office for more information. NOTE: When additional Firestats are required, install in an accessible location near an access door, hood riser, or fan. The door will provide access to install, clean, and replace the Firestat when needed. If a PCU is equipped with electronic detection, PCU Firestats can serve as downstream detectors, if present. The temperature rating of the Firestat in the duct must always match the temperature rating of the Firestat in the riser. 53 TROUBLESHOOTING Table 16 lists out causes and corrective actions for possible problems with the system.

Table 17 displays fault conditions that affect the appliances’ fuel and power sources, alarm muting, and local trouble relay. NOTE: CORE Boards with software version 1.68 and prior will use one brief flash every 3-seconds to indicate there are no faults in the fire system. NOTE: The low pressure switch option is not required per product safety listings and standards. The fault is for monitoring purposes. When the fault is present for 24 hours, cooking operation will shut down. Local Alarm Muting Pressing the fire system reset button can mute the local alarm. This will disable the sounder for 4 hours under specific conditions. Table 17 shows which errors can be muted. It should be noted that the fault will not clear until the fault condition is corrected. Test Mode Test Mode allows the system to be tested with operational appliances without discharging the system on the appli- ances. Once the appliances are started, test mode can be entered without the appliances shutting down for 15 minutes. However, once the fire system is activated, the shunt trip (electric appliances) and the gas valve will be locked out until test mode is deactivated. **During AC power failure, all gas appliances will be shut down. Electrical appliances will shut down on building power loss.

Verify there are no supervision faults on the HMI. • Verify that the hood, duct, and kitchen appliances have not changed (including type, dimensions, and location) from the approved design. Appliance drops must be between 35-50 inches from the hazard surface. • Verify that all cylinder discharge outlets are connected to the system. • Verify that all cylinders are secured in their bracket(s). • Verify that a valve cap or supervisory pressure switch (optional) is installed on each secondary cylinder Schrader valve. • Verify that nozzle caps are installed. NOTE: If this is the first service after installation, the PAK hose should be disconnected, and the primary and secondary valve actuators should be in the ship/test position. Refer to Figure 52 on page 60. Figure 51 - Electric Control Panel “Test” Mode 60 Connecting Service Test Kit CAUTION!: Supplied Nitrogen Pressure Shall Not Exceed 250 psig Maximum. NOTE: The PAK hose is shipped disconnected, and the PAK/SVA(s) are shipped in the Ship/Test position • Check the quantity of Schrader valves on the tank cylinder assembly. • Tank assemblies with one Schrader valve: - Quickly disconnect the PAK hose to minimize nitrogen loss. Verify a Supervisory Pressure Switch is active on the HMI. • Tank assemblies with dual Schrader valves: - If this is the first installation/start-up procedure, confirm a Supervisory Pressure Switch fault is active. Then, connect the PAK hose to the tank Schrader valve after the PAK/SVA actuators are con- firmed in the ship/test position. Apply Leak Lock joint sealing compound on the sealing surface of the Schrader valve when connecting the PAK hose to the tank assembly. - NEVER DISCONNECT the PAK hose from the tank during normal 6-month inspections. The pri- mary tank secondary Schrader valve will be utilized for servicing the system. A Supervisory Pres- sure Switch fault should not be active on the HMI. NOTE: PAK hoses with knurled fitting must ONLY be tightened by hand and not with a tool. If the PAK hose with a hex fitting was loosened for any reason, this fitting must be torqued to 15 in-lbs. • Remove the PAK and any Secondary Valve Actuators (SVA) from their cylinder. Place PAK and SVAs in the ship/test position. Verify that the PAK and SVAs are securely mounted to the bracket. Refer to Figure 52. Figure 52 - System Preparation • Connect the Nitrogen Service Cylinder via the 1/4” refrigerant test hose with an inline filter.

Verify the pressure reads 0 psi. Refer to Figure 58. • Prepare the tank cylinder assembly for leakage testing. • Cylinder assemblies with one Schrader valve: - Inspect the PAK hose O-ring. Replace O-ring if damaged or deformed. Refer to “TANK FIRE SUPPRES- SION SYSTEM PARTS” on page 77. - Quickly connect the PAK hose to the Schrader valve on the primary cylinder to minimize nitrogen loss. Apply Leak Lock joint sealing compound on the sealing surface of the Schrader valve when connecting the PAK hose to the tank assembly. • Cylinder assemblies with dual Schrader valves: - Place Schrader cap back on the tank cylinder secondary Schrader valve. NOTE: PAK hoses with knurled fitting must ONLY be tightened by hand and not with a tool. If the PAK hose with a hex fitting was loosened for any reason, this fitting must be torqued to 15 in-lbs. • Monitor the pressure gauge on the PAK. The pressure must not read above 0.5 psi for 15 minutes. This indi- cates the solenoid is in the de-energized state and will not let pressure through as intended. The gauge may fluctuate between 0 and 0.5 psi. CAUTION!: If pressure reads above 0.5 psi, immediately remove the primary actuator hose from the pri- mary tank. Contact Service at 1-866-784-6900. • Verify that the pistons in the PAK and SVAs are in the set position and not actuated. Refer to Figure 57 on page 63. Figure 58 - Leakage Test Setup • Install the PAK and any SVAs onto their respective cylinders. Refer to Figure 59. • Remove the pressure gauge on the PAK. Place the Schrader valve cap back onto the service port of the PAK assembly. Tighten the cap. • Spray the primary charge hose connection with a micro leak detector to check for leaks. • Verify that the Supervisory Pressure Switches have reset per the control panel manual instructions. • The system should be in the “Armed” position, and no faults should be active on the HMI when finished testing.

PAK Hose (Connected to TANK) 69 POST-DISCHARGE MAINTENANCE General Information Liquid Fire Suppressant, the Aqueous Potassium Carbonate (APC) base wet chemical used in the TANK Fire Suppression extinguishing system, is non-toxic. However, any food or cooking oils that have been contaminated with wet chemical agent should be discarded. Refer to Safety Data Sheet (SDS). After any system discharge, it is best to clean the area as soon as it is safe to do so. Prolonged exposure of equipment to wet chemical can result in localized corrosion due to moisture in the air. Clean up should be completed within 24 hours of any system discharge. TANK Fire Suppression cylinders need to be replaced every 12 years, and after any system discharge. Appliance Cleanup No unusual cleanup procedure is required. The reaction of the wet agent and the grease is one of saponification, and it produces a foam that can be wiped off. After the appliances have completely cooled, the residue from the discharge may be cleaned up using a wet cloth or sponge. Ensure that all fuel and electric power to the area has been shut down. Wear rubber gloves and eye protection while cleaning. If skin or eyes come in contact with the agent, flush thoroughly with water. Cleaning Distribution System The TANK Fire Suppression extinguishing system must have all discharge piping and nozzles flushed out with water after any discharge, as detailed in the following procedures. Cleaning Nozzles 1. Remove all nozzles from the system. 2. Inspect each nozzle & filter and remove any debris. 3. Clean nozzle and strainer by flushing thoroughly with warm soapy water. Remove any foreign matter that could impede flow. 4. Run water through the nozzle tip to ensure the orifice is not clogged. 5. Thoroughly dry nozzles with dry air or nitrogen and set aside. WARNING! Do not disturb the foam until the cooking appliances, plenum, and duct have cooled sufficiently. Do not put water on hot grease as this will cause violent steaming and spattering. WARNING! APC wet agent is electrically conductive. To avoid electrical shock, de-energize all electric circuits to appliances, outlets, and wiring by disconnecting or turning off the electric power at the main fuse or circuit breaker box. Do not cleanup APC wet agent or touch electric appliances, outlets, power cords, or other wiring with electric power on. 70 Flushing the Distribution Pipe Network Before starting the flushing procedure, inspect the complete piping network, and replace any pipe or fit- tings that have been subjected to direct flame or excessive heating. The following procedure describes flushing the pipe network with a spare/test cylinder. The pipe network can also be flushed utilizing an external water supply if available. Flushing Procedure with Spare/Test Cylinder • Check the pressure gauge on each cylinder to ensure it has been depressurized. • Clean the area with warm soapy water, and rinse with water. Dry thoroughly with dry air or nitrogen. • Disconnect the Primary Actuator Kit (PAK) stainless steel hose from the primary cylinder valve. • Remove all cylinders from the system. Refer to “Removing a Cylinder Tank (Empty or Storage)” on page 73. • Fill test cylinder(s) with water and pressurize. • Install a test cylinder for each removed cylinder. Refer to “Install New Cylinder Tank(s)” on page 74. • Attach a suitable container (or hose to a container or other point of disposal) at each pipe outlet where a nozzle was installed to collect the water discharge. • Install the PAK and SVAs onto their respective cylinders. • Re-arm the control panel by placing the package in “Armed” mode. • Connect the primary actuator hose securely to the Schrader valve on the primary cylinder. NOTE: PAK hoses with knurled fitting must ONLY be tightened by hand and not with a tool. If the PAK hose with a hex fitting was loosened for any reason, this fitting must be torqued to 15 in-lbs. • Activate the system using the manual activation device. • Once the system is fully discharged of water, reset the system. Refer to “Reset Overview” on page 50. • Remove containers or hoses from all nozzle location pipe outlets. • Remove test cylinders. • Connect a nitrogen service tank to system piping service port and blow out the discharge piping to remove all excess water. Disconnect the nitrogen service tank. Refer to “Dry the Lines” on page 72. • Install new cylinders at each location. Refer to “Install New Cylinder Tank(s)” on page 74. • Re-install nozzles, ensuring that all nozzles are in the correct location and properly aimed. • Complete the Start-up/Test Procedure. Refer to “START-UP/INSPECTION TEST PROCEDURE” on page 59. NOTE: Tank cylinder(s) should never be filled in the field with agent. 71 Flushing Procedure with an External Water Supply The procedure is used for flushing out the fire system piping after a fire system discharge. Tank cylin- der(s) must be in place when flushing the system. Refer to Figure 61 for testing setup. Parts: Flush the System • Remove the appliance nozzle that is furthest away from the utility cabinet. • Use a 3/8” to 3/4” flushing adapter to attach the hose to the nozzle drop. Attach a water hose to the flushing adapter and the other end to a water source. • Hang the bucket support brackets and buckets on the applicable drops. If possible, connect a hose to the grease spout and route the hose to the nearest floor drain. • Flush with water for a minimum of one minute. Larger systems will take longer than a minute. Figure 61 - Flushing System with External Water Supply • Remove flushing adapter. Reinstall the nozzle and hang a bucket. • When reinstalling nozzles, ensure that all nozzles are in the correct location and properly aimed. • Tank Flushing Adapter • Bucket Support Bracket • Buckets • Water Hose • Nitrogen Service Kit • Silicone Lubricant • 1/4" SAE Tee Connector with cap and valve core. 1/4" female knurl and 1/4" SAE male con- nections.

Removing a Cylinder Tank (Empty or Storage) • Unbolt the actuators from the tanks and bolt into shipped position. Repeat for all additional actuators. • Disconnect the PAK hose. IMPORTANT: If tank(s) will be stored for an extended period, you must prevent debris from entering the system. Cover the discharge outlet (tank) and discharge adapter (system piping). Install the Valve Protection Plate and Anti-recoil Plate onto the cylinder. • Use a 1/2” and 9/16” box end wrench to remove the cylinder mounting bolts from the bracket. • Loosen the tank straps, and remove the tank. Repeat for additional tanks. • For each secondary cylinder, perform the following before moving to the next cylinder: - Remove the Supervisory Pressure Switch from the cylinder valve if applicable. - Loosen the cylinder bolts holding the valve to the discharge adapter and cylinder bracket. - Loosen the tank straps holding the cylinder in place. • Pull the cylinder out from the bracket. Refer to Figure 63. Figure 63 - Tank Removal Process WARNING! Never assume that a cylinder is unpressurized. Handle all cylinders as if they are pressurized until verified otherwise. Pressurized cylinders are extremely hazardous. When performing any cylinder maintenance procedure, the cylinder must be properly secured to a rigid structure capable of withstanding the full thrust that would result if the valve were to open inadvertently. Any time a cylinder assembly is unsecured, the anti-recoil plate must be installed on the valve outlet to provide a safe, controlled discharge in the event of accidental actuation. Failure to take proper precautions could result in death, serious personal injury and/or property damage. 1. PAK in Ship/Test Position 2. SVA in Ship/Test Position 3. PAK Hose 4.
