GAS UNIT LIGHTING INSTRUCTIONS
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY
RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
A. This appliance does not have a pilot. It is equipped with an
ignition device which automatically lights the burner.
Do not try to light the pilot by hand.
B. BEFORE OPERATING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone
in your building.
• Immediately call your gas supplier from a neighbor's phone.
Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire department.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If the knob will not push in or turn by hand,
don't try to repair it, call a qualified service technician. Force
or attempted repair may result in a fire or explosion.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.

ELECTRIC HEATING SYSTEM
Heating is accomplished by passing electrical current
through a specified amount of resistance heaters which
produce the required heat. The indoor blower motor
energizes at the same time as the heaters.
STEAM OR HOT WATER HEATING SYSTEM
Heating is accomplished by passing steam or hot water
through the steam or hot water coil assembly.
COOLING SECTION • DX
All direct expansion refrigeration systems are factory
assembled, charged with refrigerant, tested and oper-
ated. On all units 8 ton and larger the refrigerant
system includes multiple circuit evaporator and con-
denser coils providing two or more stages of cooling.
These systems are provided with liquid line filter driers,
expansion valves and fully hermetic compressors.
Compressors are equipped with a positive pressure
forced lubrication system.
The air cooled condenser coil(s) are constructed of copper
tubes and mechanically bonded aluminum fins and air
pulled through by propeller fans. The evaporator coil is
draw through type constructed of copper tubes and
mechanically bonded aluminum fins.
The refrigeration section of these appliances has been
found acceptable with applicable provisions of "ANSI /
UL 1995" and current "C.S.A. Standard C22.2" by E.T.L.
NOTE: Crankcase Heater Operation
Some units are equipped with a compressor crankcase
heater, which should be energized at least 24 hours prior
to setting the thermostat for cooling operation.
COOLING SECTION • CHILLED WATER
or NON-COMPRESSORIZED UNIT
Chilled water or non-compressorized units have factory
installed coils. Systems are provided with internal
header connections for field piping. Coils are con-
structed of copper tubes and mechanically bonded alu-
minum fins.
