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.
