*Permissible limits of the voltage range at which the unit operates satisfactorily.
LEGEND:
FLA - Full Load Amps
MCA - Minimum Circuit Amps
RLA - Rated Load Amps
WIRING
All wires must be sized per NEC (National Electrical Code) or CEC
(Canadian Electrical Code) and local codes. Use Electrical Data table
MCA (minimum circuit amps) and MOCP (maximum over current
protection) to correctly size the wires and the disconnect fuse or
breakers respectively.
Recommended Connection Method for Power
and Communication Wiring:
The main power is supplied to the outdoor unit. The field supplied 14/
3 power/communication wiring, from the outdoor unit to the indoor
unit, consists of four (4) wires and provides the power for the indoor
unit. Two wires are high voltage AC power, one is communication
wiring and the other is a ground wire. Wiring between indoor
and outdoor unit is polarity sensitive. The use of BX wire is NOT
recommended.
If installed in a high Electromagnetic field (EMF) area and
communication issues exists, a 14/2 stranded shielded wire can be
used to replace L2 and (S) between outdoor unit and indoor unit
landing the shield onto ground in the outdoor unit only.

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Wires should be sized based on NEC and local codes.
CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Be sure to comply with local codes while running wire from
the indoor unit to the outdoor unit.
Every wire must be connected firmly. Loose wiring may
cause the terminal to overheat or result in unit malfunction. A
fire hazard may also exist. Ensure all wiring is tightly
connected.
No wire should touch the refrigerant tubing, compressor or
any moving parts.
Disconnecting means must be provided and shall be located
within sight and readily accessible from the air conditioner.
Connecting cable with conduit shall be routed through the
hole in the conduit panel.
