For retrofit applications, where the existing indoor evaporator coil and/or refrigerant lines will be used, the following precautions should o� be taken: o� • Ensure that the indoor evaporator coil and o� refrigerant lines are the correct size. o • Ensure that the refrigerant lines are free of leaks, acid, and oil. Important:For more information see publica- tion number SS-AP0006-EN. Section 6. Refrigerant Line Routing 6.1 Precautions Important: Take precautions to prevent noise Comply with National, State, and Local Codes when within the building structure due to vibration isolating line sets from joists, rafters, walls, or other transmission from the refrigerant lines. structural elements. For Example: • When the refrigerant lines have to be fastened to floor joists or other framing in a structure, use isolation type hangers. • Isolation hangers should also be used when refrigerant lines are run in stud spaces or enclosed ceilings. • Where the refrigerant lines run through a wall or sill, they should be insulated and isolated. • Isolate the lines from all ductwork. • Minimize the number of 90°turns. 8 Feet Maximum Joist/Rafter 0 0 / 0 0 Isolator 0 0 0 0 0 0 0 0 0 0 0 O 0 0 Side View 8 Feet Maximum Line Set Secure Vapor line from joists using isolators every 8 ft.Secure Liquid Line directly to Vapor line using tape,wire,or other appro- priate method every 8 ft.

Use a debur- ing tool to debur the pipe ends.Clean both internal and external surfaces of the tubing using an emery cloth. 0 8 11-BC26D1-11 C-EN STEP 2 - Remove the pressure tap cap and valve cores from both service valves. STEP 3 - Purge the refrigerant lines and indoor coil with dry nitrogen. O STEP 4 -Wrap a wet rag around the valve body to avoid heat damage and continue the dry nitro- gen purge. Braze the refrigerant lines to the service valves. For units shipped with a field-installed external drier, check liquid line filter drier's directional flow arrow to confirm correct direction of refrigeration flow (away from outdoor unit and toward evapo- rator coil) as illustrated. Braze the filter drier to the Liquid Line. 3-4"from valve Continue the dry nitrogen purge. Do not remove e the wet rag until all brazing is completed. e e e , Important: Remove the wet rag before stopping the dry nitrogen purge. Note: Install drier in Liquid Line. NOTE: Precautions should be taken to avoid heat damage to basepan during brazing. It is recommended to keep the flame directly off of the basepan. 11-BC26D1-11 C-EN 9 STEP 5 - Replace the pressure tap valve cores after the service valves have cooled. Section 8. Refrigerant Line Leak Check 8.1 Check For Leaks STEP 1 - Pressurize the refrigerant lines and evaporator coil to 150 PSIG using dry nitrogen. 150 PS I G STEP 2 - Check for leaks by using a soapy solu- tion or bubbles at each brazed location.

(In Heating Only) The Subcooling Charging method in cooling is not recommended below 55° F outdoor tem- perature. The only recommended method of charging at outdoor temperatures below 552 F is weighing in the charge in heating mode. STEP 1 - Determine additional charge. Note:The nameplate charge value represents Weigh-In Method can be used for the initial the amount of refrigerant shipped in the outdoor installation, or anytime a system charge is being unit and is compatible with 10 feet of AHRI rated replaced.Weigh-In Method can also be used refrigerant lines and the smallest AHRI rated when power is not available to the equipment coil. site or operating conditions (indoor/outdoor temperatures) are not in range to verify with the Using the method below, find the charge associ- subcooling charging method. ated with the additional length of tubing above 10 ft.and record it below. Calculating Charge Using the Weigh-In Method STEP 1 - Measure in feet the distance between the 1. Total Line length (ft) —10 ft outdoor unit and the indoor unit. (Include the entire length of the line from the service valve to the IDU.) 2. Charge multiplier x 0.6 oz Subtract 10 ft from this entire length and record on line 1. 3. Step 1 x Step 2 = STEP 2- Enter the charge multiplier(0.6 oz/ft). Each 4. Refrigerant (oz) _ linear foot of interconnecting tubing requires the addi- tion of 0.6 oz of refrigerant. STEP 3- Multiply the total length of refrigerant tubing (Line 1) times the value on Step 2. Record the result on Line 3 of the Worksheet. STEP 4-This is the amount of refrigerant to weigh-in prior to opening the service valves. 22 11-BCHD1-11 C-EN STEP 2 - Stabilize the system by operating for a minimum of 20 minutes. _ At startup, or whenever charge is removed or 20 MIN. added, the system must be operated for a mini- mum of 20 minutes to stabilize before accurate measurements can be made. STEP 3 - Check the liquid line temperature and liquid gage pressure to obtain a minimum of 102 subcooling in heating mode. Measured Liquid Line Temp = ° F Liquid Gage Pressure= PSIG STEP 4 -Add charge if a minimum of 10°sub- cooling is not obtained with the namplate charge plus additional charge previously added. STEP 5 - Return to site for adjustment. Important: Return in the spring or summer to accurately charge the system in the cooling mode with outdoor ambient above 551 F. Section 15. Checkout Procedures and Troubleshooting 15.1 Operational And Checkout Procedures Final phases of this installation are the unit Operational and Checkout Procedures.To obtain proper performance, all units must be operated and charge adjustments made.
