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.
18.
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 Fig. 19) 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.
