MAINTENANCE
NORMAL MAINTENANCE
Prior to any of the following maintenance pro-
cedures, shut off all electric power to the unit to
prevent personal injury.

FILTERS

Inspect once a month. Replace disposable or clean
permanent type as necessary. DO NOT replace per-
manent type with disposable. The dimensional size of
the replacement filter must be the same as the
replaced filter.

MOTORS

Outdoor fan motors are permanently lubricated and
require no maintenance.
Indoor Blower Motor and Drive - The indoor blower
motor features ball bearings that do not require
periodic lubrication. Periodic lubrication of the motor
and bearings can extend the life of components but is
optional.

drive components. Check that all mounting bolts are
tight. Replace defective parts as required.
If desired, every three years remove both pipe plugs at
each end shell and clean out any hardened grease or
foreign matter. Replace one plug on each end with a
clean grease fitting. Using a low pressure grease gun,
pump grease (Chevron SRI-2 or equivalent) into the
bearing cavity until new grease shows at the open port.
Do not over lubricate. Run the motor for ten minutes
until excess grease is purged from the cavity. Replace
the plugs.

BLOWER SHAFT BEARING

Blower shaft bearings should be inspected on a
monthly basis. At a minimum, the bearings should be
relubricated every 6 months using a lithium-based
grease (NLGI grade 2) recommended for ball bearing
service.

OUTDOOR COIL

Dirt should not be allowed to accumulate on the out-
door coil surface or other parts in the air circuit. Clean-
ing should be as often as necessary to keep coil clean.
Use a brush, vacuum cleaner attachment, or other suit-
able means. If water is used to clean coil, be sure elec-
tric power to the unit is shut off prior to cleaning.
Exercise care when cleaning the coil so that
NOTE:
the coil fins are not damaged.
