ELECTRIC SHOCK HAZARD. To prevent injury or death due
to electrical shock or contact with moving parts. Lock unit
disconnect switch in open position before servicing unit.
Cooling Season
To keep your unit operating safely and efficiently, a qualified
service technician should check the entire system seasonally,
and any other time that you feel a check is needed. Your
service technician may examine these areas of the unit:
1. filters (for possible cleaning)
2. motors (condenser and evaporator motors are perma-
nently lubricated)
3. gaskets (for possible replacement)
4. refrigerant coils (for possible cleaning)
5. safety controls (for mechanical cleaning)
6. electrical components and wiring (for possible replace-
ment and connection tightness)
7. condensate drain (for possible cleaning)
8. inspect the unit duet connections to see that they are
physically sound and sealed to the unit casing.
9. inspect the unit mounting support to see that it is sound.
10.inspect the unit to see that there is no obvious unit
deterioration.
Heating Season
At the beginning of each heating season complete the unit
inspections and service routines described in this section.
These steps should be performed ONLY by a qualified service
technician.
1. Inspect the control panel wiring and heating controls to
make sure connections are tight and wiring insulation is
intact.
2. Cheek the operation of the gas ignition system.
a. Turn the unit on and off at the thermostat to be sure
the ignition control and spark electrode are operating.
b. Turn off the gas supply with the unit operating to
verify that the gas valve closes and that a re-ignition
cycle is initiated by the ignition control.
3. Check the burner manifold pressure. A pressure tap is
provided in the gas valve for this purpose.
4. Visually inspect all of the unit's flue product passageways
for excessive deposit buildup or corrosion. If buildup or
corrosion is apparent, perform the necessary repairs.
5. Arrange for a qualified service technician to inspect the
unit every heating season to maintain safe and efficient
operation.
6. Visually check the main burner flames. They should be
bright blue flames extending up to the heat exchanger
sections.
