WIRING
All wires must be sized per NEC (National Electrical Code) or CEC
(Canadian Electrical Code) and local codes. Use the 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.
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.
To minimize communication interference: If installed in a high
Electromagnetic field (EMF) area and communication issues arise, a 14/
2 stranded shielded wire can be used to replace 2 (L2/N) and 3 (S)
between the outdoor and indoor units - landing the shield onto the
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 unit. Connecting
cable with conduit shall be routed through the hole in the conduit
panel.
