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 Fig. 21. 
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. 22) 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  Fig. 22).  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

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.
