Instruction manual
II. INDOOR BLOWER AND MOTOR
NOTE: All motors are prelubricated. 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: Disconnect and tag electrical power to the
unit before cleaning and lubricating the blower motor and
wheel. Failure to adhere to this warning could cause
personal injury or death.
III. OUTDOOR COIL, INDOOR COIL, AND CONDEN-
SATE DRAIN PAN
Inspect the condenser coil, evaporator coil, and condensate drain
pan at least once each year.
The coils are easily cleaned when dry; therefore, inspect and clean
the coils either before or after each cooling season. Remove all
obstructions, including weeds and shrubs, that interfere with the
airflow through the condenser coil.
Straighten bent fins with a fin comb. If coated with dirt or lint,
clean the coils with a vacuum cleaner, using the soft brush
attachment. Be careful not to bend the fins. If coated with oil or
grease, clean the coils with a mild detergent-and-water solution.
Rinse coils with clear water, using a garden hose. Be careful not to
splash water on motors, insulation, wiring, or air filter(s). For best
results, spray condenser coil fins from inside to outside the unit.
On units with an outer and inner condenser coil, be sure to clean
between the coils. Be sure to flush all dirt and debris from the unit
base.
Inspect the drain pan and condensate drain line when inspecting
the coils. Clean the drain pan and condensate drain by removing all
foreign matter from the pan. Flush the pan and drain trough with
clear water. Do not splash water on the insulation, motor, wiring,
or air filter(s). If the drain trough is restricted, clear it with a
“plumbers snake” or similar probe device.
IV. OUTDOOR FAN
CAUTION: Keep the condenser fan free from all ob-
structions to ensure proper cooling operation. Never place
articles on top of the unit. Damage to unit may result.
1. Remove 6 screws holding outdoor grille and motor to top
cover.
2. Turn motor/grille assembly upside down on top cover to
expose fan blade.
3. Inspect the fan blades for cracks or bends.
4. If fan needs to be removed, loosen setscrew and slide fan
off motor shaft.
5. When replacing fan blade, position blade so that the hub is
1/8 in. away from the motor end (1/8 in. of motor shaft will
be visible). (See Fig. 21)
