WIRING

NOTE: All wiring should be made in accordance with the National

Electrical Code.

Consult your local Power Company to determine the availability of

sufficient power to operate the unit. Check the voltage, frequency,

and phase at the power supply to ensure it corresponds to the unit’s

RATED VOLTAGE REQUIREMENT.

In accordance with the N.E.C. or local codes, install a branch cir-

cuit fused disconnect near the unit. Determine wire sizes and

overcurrent protection from the unit nameplate ampacity and in

accordance with the Minimum Filter Size or the N.E.C. The wiring

should never be sized smaller than is recommended by either of

these two sources.

Fuses smaller than that recommended on the rating plate could

result in unnecessary fuse failure or service calls. The use of

protective devices of larger size than indicated could result in ex-

tensive damage to the equipment. The manufacturer bears no

responsibility for damage caused to equipment as result of the

use of larger than is recommended size protective devices.

All units have undergone a run test prior to packaging for ship-

ment. This equipment has been started at minimum rated voltage

and checked for satisfactory operation. Do not attempt to operate

this unit if the voltage is not within the minimum and maximum

voltages shown on nameplate.

All exterior wiring must be within approved weatherproof conduit.

The unit must be permanently grounded in accordance with local

codes, or in absence of local codes, with N.E.C ANSI/ NFPA NO.

70-1984 or latest edition by using ground lug in the control box.

Fuses or HACR type circuit breakers may be used where codes

permit.

*NOTE

*NOTE:

LOW VOLTAGE CONNECTORS do not apply to heat pumps with

electric heat. LOW VOLTAGE CONNECTORS apply ONLY to GPC units

with electric heat.

IMPORTANT NOTE: Some single phase units are equipped with a

single-pole contactor. Exercise caution when servicing as only one

leg of the power supply is broken with the contractor.

To wire the unit, make the following high and low voltage connec-

tions.

HIGH V OLTAGE W IRING

• Single Phase- Two leads should be connected to terminals

L1 & L2 in the electrical control section, using wire sizes

specified in wiring table.

• Three Phase- Three leads should be connected to

terminals L1, L2 and L3 in the electrical section, using

wire sizes specified in wiring table.

LOW V OLTAGE W IRING

• Air Conditioners- Connect 24V wires from the thermostat

to the corresponding wires in the control box using No. 18

AWG as follows:

LEAD THERMOSTAT

Red R (24V)

Green G (Fan)

Yellow Y (Cool)

White W1 (Heat)*

Brown W2 (Heat)*

• Heat Pumps- Connect 24V wires from the thermostat to

the corresponding wires in the control box using No. 18

AWG as follows:

TERMINAL THERMOSTAT

Red R (24V)

Green G (Fan)

Orange O (Rev. Valve)

White W1 (Heat, 2nd)*

Brown W2 (Heat 3rd)*

Yellow Y (Cool)

C (Blue) C (Common)

*Optional field installed heat connections

INTERNAL W IRING

A diagram detailing the internal wiring of this unit is located on the

electrical box cover. If any of the original wire supplied with the ap-

pliance must be replaced, the wire gauge and insulation must be

the same as the original wiring.

Transformer is wired for 230 volts on the 208/230 models. See wir-

ing diagram for 208 volt wiring.

1. For branch circuit wiring (main power supply to unit

disconnect), the minimum wire size for the length of run

can be determined using the circuit ampacity found on the

unit rating plate and the table below. From the unit

disconnect to unit, the smallest wire size allowable may be

used for the ampacity, as the Disconnect must be in sight

of the unit.
