MOTORS

Outdoor fan motors are permanently lubricated and
require no maintenance.

Ventor motor is factory lubricated for an estimated 10
year life.

Indoor Blower Motor and Drive - The indoor blower
motor features ball bearings that do not require peri-
odic lubrication. However, if the motor has grease 
fittings, periodic lubrication of the motor bearings can
extend the life of components but is optional.

If desired, every three years, using a low pressure
grease gun, pump grease into the bearing grease fit-
ting until grease just begins to show at the seals. Do
not over lubricate. Use any lithium base grease recom-
mended for ball bearing service.

CONDENSER COIL

An annual check and cleaning, if necessary, of the out-
door coil should be done. Cleaning should be as often
as necessary to keep the coil clean. Clean any debris
and dirt from the outside coil face with a brush being
careful not to damage the fins. If extremely dirty, a hose
can be used to wash the coil from the inside out while
brushing a soapy solution on the outside. 

REGISTERS

Supply and return air registers must be open when the
unit is in operation. Obstructions must not be allowed
to block airflow in or out of the registers.

TROUBLESHOOTING

BEFORE CALLING A SERVICE TECHNICIAN:

A. Check thermostat setting and insure thermostat is 

calling for heat or cooling.

B. Check thermostat for lint, etc.

C. Check fuses or circuit breakers.

D. Check filters for excessive dust accumulation.

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.

Damage can occur if the bearings are overlubricated.
Use grease sparingly.
