Revised 07/2015
KGA UNITS
Service Literature 7.5 to 12.5 ton
26.3 to 42 kW
KGA092 through 150
The KGA 7.5, 8.5, 10 and 12.5 ton (092, 102, 120, 150)
packaged gas units are available in standard cooling effi
ciency. Units are available in 130,000, 180,000 or
240,000Btuh (38.1, 52.7 or 70.3 kW) heating inputs. Gas
heat sections are designed with aluminized steel tube heat
exchangers.
All KGA units are designed to accept any of several different
energy management thermostat control systems with mini
mum field wiring. Factory- or field-provided control options
connect to the unit with jack plugs. When ”plugged in” the
controls become an integral part of the unit wiring.
Information contained in this manual is intended for use by
qualified service technicians only. All specifications are sub
ject to change. Procedures outlined in this manual are pre
sented as a recommendation only and do not supersede 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 qualified installer or service
agency.
CAUTION
Electrostatic discharge can affect electronic
components. Take precautions during unit instal
lation and service to protect the unit's electronic
controls. Precautions will help to avoid control
exposure to electrostatic discharge by putting
the furnace, the control and the technician at the
same electrostatic potential. Neutralize electro
static charge by touching hand and all tools on an
unpainted unit surface, such as the gas valve or
blower deck, before performing any service pro
cedure.
ELECTROSTATIC DISCHARGE (ESD)
Precautions and Procedures
CAUTION
Danger of sharp metallic edges. Can cause injury.
Take care when servicing unit to avoid accidental
contact with sharp edges.
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.

BLOWER DATA
150 BELT DRIVE BLOWER − BASE UNIT
BLOWER TABLE INCLUDES RESISTANCE FOR BASE UNIT ONLY (NO HEAT SECTION) WITH DRY INDOOR COIL AND AIR
FILTERS IN PLACE. FOR ALL UNITS ADD:
1 − Wet indoor coil air resistance of selected unit.
2 − Any factory installed options air resistance (heat section, economizer, etc.)
3 − Any eld installed accessories air resistance (duct resistance, diffuser, etc.)
Then determine from blower table blower motor output required.
See page 10 for blower motors and drives.
See page 10 for wet coil and option/accessory air resistance data.
