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.
Outdoor Fan
1. Remove 6 screws holding condenser grille and motor to top cover.
2. Turn motor/grille assembly upside down on top cover to expose the
fan blade.
3. Inspect the fan blades for cracks or bends.
4. If fan needs to be removed, loosen the setscrew and slide the fan off
the motor shaft.
5. When replacing fan blade, position blade as shown in
6. Ensure that setscrew engages the flat area on the motor shaft when
tightening
7. Replace grille.
Electrical Controls and Wiring
Inspect and check the electrical controls and wiring annually. Be sure to
turn off the electrical power to the unit.
Remove access panels (see
) to locate all the electrical controls
and wiring. Check all electrical connections for tightness. Tighten all
screw connections. If any smoky or burned connections are noticed,
disassemble the connection, clean all the parts, restrip the wire end and
reassemble the connection properly and securely.
After inspecting the electrical controls and wiring, replace the access
panels (see
). Start the unit, and observe at least one complete
heating cycle and one complete cooling cycle to ensure proper operation.
If discrepancies are observed in either or both operating cycles, or if a
suspected malfunction has occurred, check each electrical component
with the proper electrical instrumentation. Refer to the unit wiring label
when making these checkouts.
NOTE:
Refer to the heating and/or cooling sequence of operation in
this publication as an aid in determining proper control operation
Refrigerant Circuit
Inspect all refrigerant tubing connections.

UNIT OPERATION HAZARD
Failure to follow this caution may result in damage to unit components.
Keep the condenser fan free from all obstructions to ensure proper
cooling operation. Never place articles on top of the unit.
