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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

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.
