WIRING INSTRUCTIONS
GENERAL
All wiring must be installed in accordance with the
National Electrical Code and local codes. In Canada, all
wiring must be installed in accordance with the Canadian
Electrical Code and in accordance with the regulations of
the authorities having jurisdiction. Power supply voltage
must conform to the voltage shown on the unit serial
plate. A wiring diagram of the unit is attached to the
inside of the electrical cover. The power supply shall be
sized and fused according to the specifications supplied.
A ground lug is supplied in the control compartment for
equipment ground.
The unit rating plate lists a Maximum Time Delay Fuse”
or “HACR” type circuit breaker that is to be used with
the equipment. The correct size must be used for proper
circuit protection and also to assure that there will be no
nuisance tripping due to the momentary high starting
current of the compressor motor.
CONTROL CIRCUIT WIRING
The minimum control circuit wiring gauge needed to
insure proper operation of all controls in the unit will
depend on two factors.
1. The rated VA of the control circuit transformer.
2. The maximum total distance of the control circuit
wiring.

CONTROL CIRCUIT WIRING
Example: 1. Control Circuit transformer rated at 50 VA
2.Maximum total distance of control circuit
wiring 85 feet.
From Table 5, minimum of 16 gauge wire should
be used in the control circuit wiring.
WALL THERMOSTATS
The following all thermostats and subbases should be
used as indicated, depending on the application.
