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.
Per the caution note, only stranded copper conductors with a 600
volt rating and double insulated copper wire must be used. The use
of BX cable is not recommended.
Recommended Connection Method for Power and
Communication Wiring −
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.
Recommended Connection Method for Power and
Communication Wiring (To minimize communication
wiring interference)
Power Wiring:
The main power is supplied to the outdoor unit. The field supplied
power wiring from the outdoor unit to the indoor unit consists of
three (3) wires and provides the power for the indoor unit. Two
wires are high voltage AC power and one is a ground wire. To
minimize voltage drop, the factory recommended wire size is 14/2
stranded with a ground.
Communication Wiring:
A separate shielded stranded copper conductor only, with a 600
volt rating and double insulated copper wire, must be used as the
communication wire from the outdoor unit to the indoor unit.
Please use a separate shielded 16GA stranded control wire.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
S
Wires should be sized based on NEC and local codes.
S
Use copper conductors only with a minimum 600 volt
rating and double insulated copper wire.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
S
Be sure to comply with local codes while running wire from
the indoor unit to the outdoor unit.
S
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. Therefore, ensure all wiring is
tightly connected.
S
No wire should be allowed to touch the refrigerant tubing,
compressor or any moving parts.
S
Disconnecting means must be provided and shall be located
within sight and readily accessible from the air conditioner.
S
Connecting cable with conduit shall be routed through a hole
in the conduit panel.
