TO AVOID PERSONAL INJURY OR DEATH DUE TO EXPLOSION OR FIRE, THE
FOLLOWING PROCEDURES MUST BE FOLLOWED EXACTLY IN SEQUENCE
BEFORE INSPECTING THE UNIT:
• TURN OFF GAS BY CLOSING EXTERNAL GAS SHUTOFF VALVE TO THE UNIT
• TURN OFF ELECTRICAL POWER BY OPENING UNIT POWER DISCONNECT.
• IF THE UNIT HAS BEEN OPERATING, WAIT 15 MINUTES FOR IT TO COOL.
ANNUAL INSPECTION
Your package unit should be inspected by a qualified installer, or
service agency at least twice every year. This check should be
performed before the heating and cooling seasons begin. This will
ensure that adequate combustion air is being drawn and the vent
system is working properly. Particular attention should be paid to
the following items. Repair as necessary.
• Check physical support of the unit. Ensure it is sound without
any sagging, cracks, or gaps, around the base.
• Check for obvious signs of deterioration of the unit.
• Flue Hood. Check for blockage (wasp nest, etc.) and corro-
sion.
Flue Hood
• Return Air Connection. Check for physical soundness and
ensure that the connection is firmly sealed to the package unit
casing.
• Heat exchanger. Check for corrosion and/or obstructions within
the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and flame
sense.
• Wiring. Check electrical connections for tightness and/or cor-
rosion. Check wires for damage.
• Filters. Check that filters are clean and in the proper place-
ment in the unit or duct system.
• Louvers. Inspect air inlet louvers inside the heat exchanger
compartments. Ensure the area is clean and free of dirt and
debris.
REPLACING OR CLEANING FILTER
IMPORTANT NOTE: Never operate unit without a filter installed
as dust and lint will build up on internal parts resulting in loss of
efficiency, equipment damage and possible fire.
A return air filter is not supplied with this unit; however, there must
be a means of filtering the return air. The filter{s) may be located
in the return air duct(s). Consult with your installing dealer for the
actual location of the return air filter(s) in your unit.
A dirty filter is the most common cause of inadequate heating or
cooling performance. Filter inspection should be made at least every two
months; more often if necessary because of local conditions and usage.
Dirty throw away filters should be discarded and replaced with a new,
clean filter. Dirty permanent filters should be washed with water, thor-
oughly dried and sprayed with a filter adhesive before being reinstalled.
(Filter adhesives may be found at many hardware stores.) Permanent
filters should last several years. However, should one become forn or
uncleanable, it should be replaced.
When installing a new filter or reinstalling an old one, always make certain
the air flow arrows on the filter point in the proper direction.
CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)
TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK,
DISCONNECT THE ELECTRICAL SWITCH BEFORE CLEANING THE COIL(S).
The coil with the outside air flowing over it should be inspected annually
and cleaned as frequently as necessary to keep the finned areas free of
leaves, grass, seeds, and debris.
CONDENSER, EVAPORATOR, AND INDUCED DRAFT MOTORS
Bearings on the air circulating blower motor, condenser motor and the
combustion fan motor are permanently lubricated. No additional oiling is
required.
COMPRESSOR
The compressor motor is hermetically sealed and does not require
additional oiling.
