WALL-MOUNT UNIT SUPPLY WIRING
Refer to the unit rating plate or Table 1.1 for wire
sizing information and maximum fuse or circuit breaker
size. Each outdoor unit is marked with a “Minimum
Circuit Ampacity”. The field wiring used must be sized
to carry that amount of current. All models are suitable
only for connection with copper wire. Each unit and/or
wiring diagram will be marked “Use Copper Conductors
Only”. These instructions
must be adhered to. Refer
to the National Electrical Code (NEC) for complete
current carrying capacity data on the various insulation
grades of wiring material. All wiring must conform to
NEC and all local codes.
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest
version), Article 310 for power conductor sizing.
CAUTION: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to
note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a
raceway.
Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
Based on 75°C copper wire. All wiring must conform to the National Electric Code and all local codes.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuse and conductor
wires in accordance with the National Electrical Code and all local codes.

Electrical Specifications
All models covered by this installation
instruction require
VAC utility power to run
the compressor, heat, outdoor fan motor,
indoor blower and free cooling damper.
Electrical shock hazard.
Have a properly trained individual perform
these tasks.
Failure to do so could result in electric shock
or death.
