KHA SERIES
The KHA commercial heat pump is available in 2, 2.5, 3, 4
and 5 ton capacities. The KHA024/060 refrigerant systems
utilize one compressor, one reversing valve and other parts
common to a heat pump. Optional auxiliary electric heat is
field installed in KHA units. Electric heat operates in single
stage. 7.5kW through 22.5kW heat sections are available
for the KHA heat pump.
Information contained in this manual is intended for use by
qualified service technicians only. All specifications are
subject to change. Procedures outlined in this manual are
presented as a recommendation only and do not super-
sede or replace local or state codes.
If the unit must be lifted for service, rig unit by attaching four
cables to the holes located in the unit base rail (two holes at
each corner). Refer to the installation instructions for the
proper rigging technique.
WARNING
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, person-
al injury or loss of life. Installation and service must
be performed by a licensed professional installer (or
equivalent), service agency or the gas supplier.
CAUTION
Danger of sharp metallic edges. Can cause injury.
Take care when servicing unit to avoid accidental
contact with sharp edges.
ELECTROSTATIC DISCHARGE (ESD)
Precautions and Procedures
CAUTION
Electrostatic discharge can affect electronic com-
ponents. Take precautions during unit installation
and service to protect the unit’s electronic con-
trols. Precautions will help to avoid control expo-
sure to electrostatic discharge by putting the unit,
the control and the technician at the same electro-
static potential. Neutralize electrostatic charge by
touching hand and all tools on an unpainted unit
surface before performing any service procedure.
WARNING
Electric shock hazard. Can cause injury
or death. Before attempting to perform
any service or maintenance, turn the
electrical power to unit OFF at discon-
nect switch(es). Unit may have multiple
power supplies.

1 2 hp blower motor is not available for 208/230V-1ph applications.
2 Lamps operate on 110-230V single-phase power supply. Step-down transformer may be ordered separately for 460V and 575V units. Alternately, 110V power supply
may be used to directly power the UVC ballast(s).
