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.
