How to maintain the roof air conditioner of the RV?

1、AIR FILTER:
Periodically remove the return air filter located above the removablepanel in the air box. Wash the filter with soap and warm water, let dry and then reinstall.
Note:Never run the air conditioner without return air filter in place.This may plug the unit evaporator coil with dirt and may substantially affect the performance of the unit.
2、AIR BOX HOUSING:
Clean air box housing and control panel with a soft cloth dampened with a mild detergent. Never use furniture polish or scouring powders.
3. FAN MOTOR:
Factory lubricated and requires no service under normal use.
4. FROST FORMATION ON COOLING COIL:
Under certain conditions, frost may form on the evaporator coil. If this should occur, inspect the filter and clean if dirty. Make sure air louvers are not obstructed. Air conditioners have a greater tendency to frostwhen the outside temperature is relatively low. This may be preventedby adjusting the thermostat control knob to a warmer setting(counter clockwise). Should frosting continue, operate on LOW, MED. orHIGH FAN setting until the cooling coil is free of frost.
