MAINTENANCE
EVAPORATOR COIL
Do not allow dirt to accumulate on the evaporator coil
or other parts of the evaporator air circuit. Clean as
often as necessary to assure good system perfor-
mance. Use a brush, vacuum cleaner attachment or
other suitable means.
FILTERS
The filters must be replaced as often as necessary to
assure good air flow and filtering action.
Refer to Figure 10 for filter access panel location.
DRAIN PAN
The drain pan should be inspected regularly to assure
proper drainage.
LUBRICATION
The bearings for the blower shaft and the blower
motors are permanently lubricated and should not
require additional lubricant.
BELTS
Maintain belt tension to extend belt life. Replace when
signs of failure begin to appear.
