!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Disconnect and install lockout tag on electrical power to the unit before cleaning and lubricating the blower motor and wheel.

To clean the blower motor and wheel:

1.Remove and disassemble blower assembly as follows:

a.Remove blower access panel (see Fig. 20).

b.Disconnect 5 pin plug and 4 pin plug from indoor blower motor. Remove capacitor if required.

c.On all units remove blower assembly from unit. Remove 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.

e.Loosen setscrew(s) that secures wheel to motor shaft, remove screws that secure motor mount brackets to housing, and slide motor and motor mount out of housing.

2.Remove and clean blower wheel as follows:

a.Ensure proper reassembly by marking wheel orientation.

b.Lift wheel from housing. When handling and/or cleaning blower wheel, be sure not to disturb balance weights (clips) on blower wheel vanes.

c.Remove caked-on dirt from wheel and housing with a brush. Remove lint and/or dirt accumulations from wheel and housing with vacuum cleaner, using soft brush attachment. Remove grease and oil with mild solvent.

d.Reassemble wheel into housing.

e.Reassemble motor into housing. Be sure setscrews are tightened on motor shaft flats and not on round part of shaft. Reinstall blower into unit. Reinstall capacitor if required.

f.Connect 5 pin plug and 4 pin plug to indoor blower motor.

g.Reinstall blower access panel (see Fig. 20).

3.Restore electrical power to unit. Start unit and check for proper blower rotation and motor speeds during cooling cycles.

Step 2 — Outdoor Coil, Indoor Coil, and Condensate 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.

Step 3 — Outdoor Fan

Keep the condenser fan free from all obstructions 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 back to same posi- tion as before.

6.Ensure that setscrew engages the flat area on the motor shaft when tightening.

7.Replace grille.
