1)Confirm system selection. Optional components may be field or factory installed.
2)If LPS and/or HPS not installed or removed, a jumper wire must be present across circuit for system to operate.
3)For proper system operation, consult indoor unit and outdoor unit installation instructions to confirm system match up and blower speed selection.
4)Alternate double pole contactor used on some systems.
5)Only one start assist method to be used at a time, consult outdoor unit installation instructions for application information. Use only factory approved accessories.
6)Optional OFM components may connect capacitor common and motor common, for reciprocating compressor there may have crankcase heater consult outdoor unit installation instructions for details. Select the running capacitor(one or dual) and connect. If IFM or OFM only have one capacitor wire, connect Com wire to capacitor.
7)Indoor unit shipped without optional electric heater kit. To install optional heater kit, remove power pig tail up to 9 pin plug. Install heater kit and connect with mating 9 pin plug. Run system power connections directly to electric heater kit power terminals. Consult heater kit installation instructions for complete details.
