Heat Exchanger —
To ensure dependable and efficient
heating operation, the heat exchanger should be checked by a
qualified maintenance person before each heating season, and
cleaned when necessary. This checkout should not be attempt-
ed by anyone not having the required expertise and equipment
to do the job properly. Checking and/or cleaning the heat ex-
changer involves removing the gas controls assembly and the
flue collector box cover and, when completed, reinstalling the
gas controls assembly for proper operation. Also, the flue col-
lector box cover must be replaced correctly so that a proper
seal is maintained. Contact your dealer for the required period-
ic maintenance.
Fans and Belts —
Periodically check the condition of
fan wheels and housings, and belt tension. When service is nec-
essary, call your dealer.
Evaporator-, Condenser-, and Combustion
Fan Motors —
Lubrication is not recommended. Bearings
will not require lubrication for at least 5 years of normal opera-
tion. After 5 years, motor life can be extended by having the
motors serviced at an authorized motor service shop.
Fan Shaft Bearings —
Lubrication should only be done
by qualified service personnel. Contact your dealer for the re-
quired annual maintenance.
Evaporator and Condenser Coils —
Cleaning of the
coils should only be done by qualified service personnel. Con-
tact your dealer for the required annual maintenance.
Condensate Drain —
The drain pan and condensate
drain line should be checked and cleaned at the same time the
cooling coils are checked by your dealer.
Compressors —
All compressors are factory shipped
with a normal charge of the correct type refrigerant grade oil in
them and should rarely require additional oil. The service tech-
nician must be certain the proper oil level is maintained in the
compressor when it is installed and running.
