VII. Condenser Fan
WARNING: Do not poke sticks, screwdrivers, or
any other object into revolving fan blades. Severe
bodily injury may result.
The fan must be kept free of all obstructions to ensure proper
cooling. Contact your dealer for any required service.
VIII. Electrical Controls and Wiring
Electrical controls are difficult to check without proper
instrumentation; therefore, if there are any discrepancies in
the operating cycle, contact your dealer and request service.
IX. Refrigerant Circuit
The refrigerant circuit is difficult to check for leaks without
the proper equipment; therefore, if inadequate cooling is sus-
pected, contact your local dealer for service.
X. Combustion Area and Vent System
The combustion area and vent system should be visually
inspected before each heating season. The normal accumula-
tion of dirt, soot, rust, and scale can result in loss of effi-
ciency and improper performance if allowed to build up.
CAUTION: If your unit makes an unusual or espe-
cially loud noises during heating, shut down the heat-
ing section and call your dealer.
See Fig. 1A, 1B and 5 and proceed as follows to inspect the
combustion area and power-venting system of your unit.
1. Turn off gas supply to your unit.
2. Turn off electrical power to your unit and install lock-
out tag.
3. Remove burner access panel.
4. Using a flashlight, carefully inspect the burner areas
for dirt, soot, rust or scale.
CAUTION: If dirt, soot, rust, or scale accumula-
tions are found, call your dealer and do not operate
your heating section.

5. When you have completed your inspection, follow the
start-up procedures in this manual to restore your
unit to operation.

WARNING: Components in heat section may be
hot after unit has been started up. When observing
flame, be careful not to get to close to or touch heating
components. Serious personal injury may result.
Watch the burner flame to see if it is bright blue. If
you observe a suspected malfunction or that the
burner flame is not bright blue, call your dealer.
7. Replace burner access panel.
XI. Unit Panels
After performing any maintenance or service on the unit, be
sure all panels are securely fastened in place to prevent rain
from entering unit cabinet and to prevent disruption of the
correct unit airflow pattern.

REGULAR DEALER MAINTENANCE

In addition to the type of routine maintenance you might be
willing to perform, your unit should be inspected regularly
by a properly trained service technician. An inspection (pref-
erably each year, but at least every other year) should
include the following:
1. Inspection of all flue product passages — including
the burner, heat exchanger, and flue collector box.
2. Inspection of all combustion- and ventilation-air
passages and openings.
3. Close inspection of all gas pipes leading to and inside
your unit.
4. Inspection, and if required, cleaning of the condenser
and evaporator coils.
5. Inspection, and if required, cleaning of the conden-
sate drain pan and trap.
6. Inspection of all supply- and return-air ducts for
leaks, obstructions, and insulation integrity. Any
problems found should be resolved at the time of
inspection.
7. Inspection of the unit base for cracks, gaps, etc.,
which may cause a hazardous condition.
8. Inspection of
deterioration.
9. Inspection of all electrical wiring and components to
ensure proper connection.
10. Inspection for leaks in the refrigerant circuit.
Pressure-check to determine appropriate refrigerant
charge.
11. Inspection and cleaning of fan wheels and housings,
belt tension, and fan motor, shaft bearings, and pul-
ley alignment.
12. Operational check of the unit to determine working
conditions. Repair or adjustment should be made at
the time of inspection.
Your servicing dealer may offer an economical service con-
tract that covers seasonal inspections. Ask for further
details.
