and Heat Pumps
DEALER SETUP CHECKLIST
Remove from literature packet and place in customer file at dealership.
NOTE: Read the entire installation instruction manual before starting the installations.
Check equipment for shipping damage. Note damages: ____________________________________
_____ Locate and level the unit. See Installation Instructions under Install on a Solid, Level Mounting Pad and Clear-
ance Requirement sections.
_____ Elevate the unit to ensure proper drainage.
_____ Connect power and control wiring connections. See Installation Instruction under Make Electrical Connections
section and 24- V circuit connection figures. Isolate control and high voltage wiring as much as possible. Elec-
trical noise from high voltage wires may cause communication issues. There could be spare low voltage wires;
keep the factory cap secured.
_____ Apply high voltage to unit for 24 hours before attempting to operate. Nuisance fault codes may be generated if
the unit attempts to run while a large quantity of liquid refrigerant is in compressor.
Power Supply Voltage: ____________ Volts Control Voltage: ______________Volts
_____ Check factory wires and wire connections to ensure terminations are fully seated and secured properly. See
wiring label on unit for proper wiring identification.
_____ Check wire routing to ensure wires are not in contact with tubing or sheet metal. Check wire routing around fan
motor to ensure wires will not come in contact with fan blades. Isolate high voltage wiring from low voltage,
control, and sensor wires to prevent electrical noise.
_____ Check field wiring for proper support, termination, tightness, and grounding. Ensure a quality earth ground is
available and connected.
_____ Install proper wire size and fuse/circuit breaker. Consult Product Data Sheet and/or local codes for recom-
mended wire size and fuse/circuit breaker.
_____ For heat pumps, check the defrost sensor to ensure proper location and attachment. See the defrost sensor
location illustration in the Installation Instructions.
_____ Check factory tubing to ensure tubes are not rubbing against each other or any sheet metal. Pay close atten-
tion to feeder tubes on both indoor and outdoor coils. Ensure wire ties are tight.
_____ Ensure proper line set sizes are used. See Installation Instructions under Make Piping Connections section and
Refrigerant Connections and Recommended Liquid and Vapor T ube Diameters table.
_____ If line sets exceed 80 ft and/or exceeds 3 ft of buried line, see Installation Instructions Accessory Usage table
for required accessories and appropriate Residential Split System Application Guidelines. 5- stage models are
limited to 100 equivalent ft of line set length.
_____ Install solenoid valve (when required) and filter drier. Consult Product Data Sheet for proper accessory kit.
5- stage models do not require liquid line solenoids.
_____ Evacuate line set and indoor coil.
_____ Open refrigerant valves and check refrigerant charge. See Installation Instructions under Check Charge sec-
tion. Use subcooling charging method if temperature allows. If ambient temperature is outside allowable range
for subcooling charging method, weigh in additional refrigerant based on indoor coil match and line set length.
W all control charging screen will display required charge in pounds and ounces. Outdoor unit rating plate lists
charge as a decimal value. Wait a minimum of 20 minutes for subcooling to stabilize before adding or removing
charge. Due to the small size of some of these products, they are very sensitive to overcharging and may gen-
erate nuisance fault codes.
_____ Check refrigerant connections for leaks.
Suction Pressure: _____________ psig Outdoor Temperature: ________________°F
Liquid Pressure: ______________ psig Indoor Temperature: __________________°F
Superheat/Subcooling: _________________° F
_____ If unit is installed in a sea coast or low- ambient application, see Installation Instructions Accessory Usage ta-
ble. 5- stage models will operate in cooling mode to 55°F in non- communicating mode or 40°F in communicat-
ing mode. No low ambient cooling mode is available for 5- stage models.
_____ If thermostatic expansion valve (TXV) is used, make sure the TXV is for use with outdoor unit refrigerant and is
of proper size. Piston is not needed when TXV is used. 5- stage models and variable speed models require use
of TXV for cooling operation.
