A. AIR FILTER
CAUTION: Never operate the unit without a suitable air
filter in the return-air duct system. Always replace the
filter with the same dimensional size and type as origi-
nally installed (See Tables 1 and 2 for recommended filter
sizes).
Inspect air filter(s) at least once each month and replace
(throwaway-type) or clean (cleanable-type) at least twice during
each heating and cooling season or whenever the filter(s) becomes
clogged with dust and/or lint.
B. EVAPORATOR BLOWER AND MOTOR
NOTE: All motors are permanently lubricated. Do not attempt to
lubricate these motors.
For longer life, operating economy, and continuing efficiency,
clean accumulated dirt and grease from the blower wheel and
motor annually.
WARNING: Before cleaning the blower motor and
wheel, disconnect gas supply. Then turn off and tag
electrical power to the unit. Failure to adhere to this
warning could cause serious injury or death.
CLEANING THE BLOWER MOTOR AND WHEEL
1. Remove and disassemble blower assembly as follows:
a. Remove unit access panel.
b. Disconnect motor lead from blower relay (BM). Discon-
nect yellow lead from terminal L2 of the contactor.
c. On all units, remove blower assembly from unit. Re-
move screws securing blower to blower partition and
slide assembly out. Be careful not to tear insulation in
blower compartment.
d. Ensure proper reassembly by marking blower wheel and
motor in relation to blower housing before disassembly.
