Electric Heat Installation and Adjustment

This series of electric cooling and heat pump package equipment

is designed to accept a field installed electric heat kit. The unit is

equipped to easily install the HKR Series Electric Heat Kit. Full

installation instructions are included in this kit. Please use this

document for guidance in field equipping the package unit with

electric heat.

Choose the heat kit that fits the application for the specific

installation. Permanently mark the unit’s nameplate with the

model being installed. High and low voltage connections are

detailed in the heat kit instructions.

Indoor blower motor speed tap selection may need to be

modified to accommodate normal continuous operation to

prevent a nuisance trip. See the following charts.

All models are factory-shipped at T3 speed.

Make Electrical Connections

Wiring

All wiring should be made in accordance with the National

Electrical Code (N.E.C). The local power company should be

consulted to determine the availability of sufficient power to

operate the unit. The voltage, frequency and phase at the power

supply should be checked to make sure it corresponds to the

unit’s rated voltage requirement.

Install a branch circuit fused disconnect near the unit, in

accordance with the N.E.C. or local codes. Wire sizes and over-

current protection should be determined from the unit nameplate

ampacity and in accordance with Branch Circuit Ampacity chart

or the N.E.C. Under no circumstances should wiring be sized

smaller than is recommended by either of these 2 sources.

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.

High Voltage Wiring

Single Phase—Connect the 2 leads to terminals L1 and L2 in the

electrical control section, using wire sizes specified in the wiring

table.
