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.

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.
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 Fig.
20.
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 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. 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 and the unit base for oil
accumulations annually. Detecting oil generally indicates a
refrigerant leak.
