Maintenance

Normal Maintenance

Prior to any of the following maintenance procedures,
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 permanent 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.
Damage can occur if the bearings are over-lubricated.
Use grease sparingly.
Johnson Controls Unitary Products
Perform all maintenance operations on the blower motor
with electric power disconnected from the unit. Do not
attempt to lubricate bearings with the unit in operation.
On an annual basis, check the motor for accumulations of dust,
etc. that may block the cooling slots in the motor shell. Check
for loose, damaged or misaligned 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 re-lubricated 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 outdoor coil
surface or other parts in the air circuit. Cleaning should be as
often as necessary to keep coil clean. Use a brush, vacuum
cleaner attachment, or other suitable means. If water is used to
clean coil, be sure electric power to the unit is shut off prior to
cleaning.
NOTE: Exercise care when cleaning the coil so that the coil fins
are not damaged.
