11-AC29D1-10D-EN 3
2.4 Cold Climate Considerations
NOTE: It is recommended that these precautions be taken for units being installed in areas where snow accumula-
tion and prolonged below freezing temperatures occur.
• Units should be elevated 3-12 inches above the pad or rooftop, depending on local weather.This additional
height will allow drainage of snow and ice melted during defrost cycle prior to its refreezing. Ensure that drain
holes in unit base pan are not obstructed preventing draining of defrost water.
• If possible, avoid locations that are likely to accumulate snow drifts. If not possible, a snow drift barrier should be
installed around the unit to prevent a build-up of snow on the sides of the unit.
2.5 Coastal Considerations
If installed within one mile of salt water, including seacoasts and inland waterways, models without factory sup-
plied Seacoast Salt Shields require the addition of BAYSEAC001 (Seacoast Kit) at installation time.
Section 3. Unit Preparation
3.1 Prepare The Unit For Installation
STEP 1 - Check for damage and report promptly to the carrier any damage found to the unit.
STEP 2 -To remove the unit from the pallet, remove tabs by cutting with a sharp tool.
Section 4. Setting the Unit
4.1 Pad Installation
When installing the unit on a support pad, such as a concrete slab, consider the following:
• The pad should be at least 1"larger than the unit on all sides.
• The pad must be separate from any structure.
• The pad must be level.
• The pad should be high enough above grade to allow for drainage.
• The pad location must comply with National, State, and Local codes.
For other applications refer to application guide.

5.4 Refrigerant Line Insulation
Important: The Vapor Line must always be
insulated. DO NOT allow the Liquid Line and Liquid Line vapor Line
Vapor Line to come in direct(metal to metal) Insulation
contact.
5.5 Reuse Existing Refrigerant Lines
If using existing refrigerant lines make certain that all joints are brazed, not soldered.
For retrofit applications, where the existing indoor evaporator coil and/or refrigerant lines will be used, the following
precautions should be taken:
• Ensure that the indoor evaporator coil and refrigerant lines are the correct size.
• Ensure that the refrigerant lines are free of leaks, acid, and oil.
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 90L turns.

Section 7. Refrigerant Line Brazing
7.1 Braze The Refrigerant Lines
STEP 1 - Remove caps or plugs. Use a deburing tool to debur the pipe ends. Clean both internal and external
surfaces of the tubing using an emery cloth.
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.
STEP 4 -Wrap a wet rag around the valve body to avoid heat damage and continue the dry nitrogen 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 evaporator coil) as illustrated. Braze the
filter drier to the Liquid Line.
Continue the dry nitrogen purge. Do not remove the wet rag until all brazing is completed.
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.
STEP 5 - Replace the pressure tap valve cores after the service valves have cooled.

14.3 Subcooling Charging Below 550 F Outdoor Temp. (In Heating Only)
The Subcooling Charging method in cooling is not recommended below 559 F outdoor temperature.
The recommended method of charging at outdoor temperatures below 55° F is weighing in the charge. Return
when weather conditions permit charge verification through subcooling.
STEP 1 - Determine additional charge.
Note:The nameplate charge value represents the amount of refrigerant shipped in the outdoor unit and is com-
patible with 10 feet of AHRI rated refrigerant lines and the smallest AHRI rated coil.
Using the method below, find the charge associated with the additional length of tubing above 10 ft.and record
it below.
Weigh-In Method can be used for the initial installation, or anytime a system charge is being replaced.Weigh-In
Method can also be used when power is not available to the equipment site or operating conditions (indoor/out-
door temperatures) are not in range to verify with the subcooling charging method.
Calculating Charge Using the Weigh-In Method
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 2. Charge multiplier x 0.6 oz
valve to the IDU.) Subtract 10 ft from this
entire length and record on line 1. 3. Step 1 x Step 2 =
2) Enter the charge multiplier(0.6 oz/ft). Each 4. Refrigerant (oz) _
linear foot of interconnecting tubing requires
the addition of 0.6 oz of refrigerant.
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.
4) This is the amount of refrigerant to weigh-in
prior to opening the service valves.
STEP 2 - Stabilize the system by operating for a minimum of 20 minutes.
At startup, or whenever charge is removed or added, the system must be operated for a minimum 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 10°subcooling in
heating mode.
Measured Liquid Line Temp = ° F
Liquid Gage Pressure = PSIG
STEP 4 -Add charge if a minimum of 10°subcooling 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 550 F.

Section 18. Pressure Curves
COOLING PERFORMANCE CAN BE CHECKED WHEN THE OUTDOOR TEMP IS ABOVE 65 DEG F.
TO CHECK COOLING PERFORMANCE,SELECT THE PROPER INDOOR CFM,ALLOW PRESSURES TO STABILIZE. MEASURE INDOOR WET BULB
TEMPERATURE,OUTDOOR TEMPERATURE,LIQUID AND SUCTION PRESSURES. ON THE PLOTS LOCATE OUTDOOR TEMPERATURE(1);
LOCATE INDOOR WET BULB(2); FIND INTERSECTION OF OD TEMP.&ID W.B.(3);READ LIQUID(4)OR SUCTION(5)PRESSURE IN LEFT COLUMN.
EXAMPLE:(1)OUTDOOR TEMP.82 F.
(2)IN DOOR WET BULB 67 F.
(3)AT INTERSECTION ACTUAL:
(4)LIQUID PRESSURE @ 600 CFM IS 304 PSIG LIQUID PRESSURE SHOULD BE+/-10 PSI OF CHART
(5)SUCTION PRESSURE @ 600 CFM IS 145 PSIG SUCTION PRESSURE SHOULD BE+/-3 PSIG OF CHART
