Specifications subject to change without notice.
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 caution note, only Stranded copper conductors with a 600 volt
rating and double insulated copper wire must be used.
NOTE: 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)
PowerWiring:
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 minimum
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.
Wires should be sized based on NEC and local codes.
Use copper conductors only with a 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 indoor unit to outdoor unit.
S Every wire must be connected firmly. Loose wiring may
cause terminal to overheat or result in unit malfunction.
A fire hazard may also exist. Therefore, be sure all
wiring is tightly connected.
S No wire should be allowed to touch 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
hole in the conduit panel.
