MAINTENANCE
INDOOR COIL
Do not allow dirt to accumulate on the indoor coil or
other parts of the supply/return air circuit. Clean as
often as necessary to assure good system perfor-
mance. Use a brush, vacuum cleaner attachment or
other suitable means.
If the coil becomes extremely dirty, it may be neces-
sary to use an industrial grade detergent and a hose to
clean the finned surfaces. This is recommended to pre-
vent any loss in capacity and efficiency.
FILTERS
The filters must be replaced as often as necessary to
assure good air flow and filtering action. Clean filters
will prevent any loss in capacity and efficiency.
Refer to the unit drawing in Figure 14 for the location of
the filter access panel.
DRAIN PAN
The condensate drain pan should be inspected regu-
larly to assure proper drainage.
LUBRICATION
The bearings for the blower shaft and the blower motor
are permanently lubricated and should not require any
additional lubricant.
BELTS
Maintain belt tension to extend belt life. Replace when
signs of failure begin to appear.
