GENERAL INFORMATION
H5HK Heater Kits are approved for use in the
packaged Air Conditioners and Packaged Heat
Pumps as listed when applied and installed
according to these instructions. See Table 1
for the approved H5HK combinations. Refer
to the National Electric Code (ANSI/NFPA 70)
or in Canada the Canadian Electric Code Part
1 (CSA C.22.1) and applicable local codes for
over-current protection and disconnect require-
ments.
If any of the original wiring as supplied with the
unit must be replaced, it must be replaced with
material of the same gauge and temperature
rating.
ELECTRICAL SUPPLY
WARNING:
To avoid the risk of electric shock,
personal injury, or death, disconnect
all electrical power to the unit before
performing any maintenance or
service. The unit may have more
than one electrical power supply.
If the unit was previously installed without electric
heat, the existing supply wiring may not be
sufficient to handle the increased load. See the
unit ratings label in Table 2 for minimum circuit
ampacities and maximum over-current protection
ratings. The units with installed electric heat may
be supplied by a single circuit or dual circuits.
An additional accessory kit is required if dual
electrical circuit installation is desired. See Table
1 for accessory description and part number.
INSTALLATION PREPARATIONS
Before proceeding with the electrical connec-
tions, make certain that the voltage, frequency,
and phase of the supply source are the same
as those specified on the unit rating label. Also
verify that the service provided by the utility is
sufficient to handle the additional load imposed
by this equipment.
CIRCUIT OPTIONS
Units installed with electric heat may be wired for
single or multiple circuit supply connections.
Single Circuit - Units are factory ready for
addition of heater kits. See unit rating label
for Minimum Circuit Ampacity and Maximum
OverCurrent Protection of supply wiring.
Multiple Circuit - For Dual Electrical Supply
connections see the unit rating plate or Table
2, Electrical Data for proper high voltage wiring
requirements. Use NORDYNE P/N-917468, 3
Pole Dual Circuit Adaptor for converting to dual
supply connections. Refer to the instructions
included with the 3 Pole Dual Circuit Adaptor kit
for details on how to configure the adaptor for
proper Cooling operation hookup.
NOTE: Circuit Breakers installed in the unit
with the addition of heater kits are for short
circuit protection of the internal heater ele-
ment circuit wiring and DO NOT serve as a
disconnect. The circuit breakers DO NOT
provide over-current protection of the sup-
ply wiring.
