Cleaning The Air Filter; Troubleshooting Guide - Fedders A6U10W2A Operating Instructions Manual

Cleaning the air filter

EVERY TWO WEEKS: Clean the filter.
1. Turn Power OFF.
2. Remove the air filter by grasping the top corners and pulling
it up and out of the unit. (Fig. 15)
3. Wash in hot soapy water, rinse and shake dry.
4. Replace the filter with the front of the filter toward you.
5. To dry the filter thoroughly, run your unit in fan mode for a
few minutes. Remember, only a clean filter works properly
and delivers top efficiency at every setting.
Note: Failure to keep air filter clean will result in poor air
circulation. DO NOT operate without filter. This can render the
unit inoperative.
Proper use and care of your air conditioner will help ensure
longer life of the unit. It is recommended to have a
professional annually inspect and clean the coils and
condensate water passages. Expense of annual inspection is
the consumer's responsibility.
