Indoor Blower Motor and Drive - The indoor blower motor fea-
tures ball bearings that do not require periodic 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 fitting until grease
just begins to show at the seals. Do not over lubricate. Use
any lithium base grease recommended for ball bearing ser-
vice.
CONDENSER COIL
An annual check and cleaning, if necessary, of the outdoor
coil should be done. Cleaning should be as often as neces-
sary 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 air-
flow in or out of the registers.
