Fuses smaller than that recommended on the wiring diagrams

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

of protective devices of larger size than indicated could result in

extensive 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

shipment. 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: Some single-phase units are equipped with a single-pole

contactor. Caution must be exercised when servicing as only

1 leg of the power supply is broken with the contactor.

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

connections:

High Voltage Wiring

Single Phase—2 leads should be connected to terminals L1 and

L2 in the electrical control section, using wire sizes specified in

the wiring table.

Low Voltage Wiring

■ Air Conditioners—Connect 24V wires from the thermostat to

the corresponding wires in the control box using 18 AWG as

follows:

*Optional field installed heat connections

■ Heat Pumps—Connect 24V wires from the thermostat to the

corresponding wires in the control box using 18 AWG as

follows:

*Optional field installed heat connections

Internal Wiring

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 appliance 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

the wiring diagram for 208-volt wiring.

■ For branch circuit wiring (main power supply to unit

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

can be determined from the Branch Circuit Ampacity chart

using the circuit ampacity found on the unit rating plate. From

the unit disconnect to the unit, the smallest wire size

allowable in the Branch Circuit Ampacity chart may be used

for the ampacity, as the disconnect must be in sight of the

unit.

■ Wire size based on 60ºC rated wire insulation and 86ºF (30ºC)

ambient temperature.

■ For more than 3 conductors in a raceway or cable, see the

N.E.C. for derating the ampacity of each conductor.
