F. ChecktheAirFilter
A dirty air filter will cause excessive strain on the compressor and blower motor. This can cause the components to overheat and autonmtically
shut down. In the worst case, the components will fail and need to be replaced. To avoid inefficient or failed operation of your unit, CHECK THE
FILTER(S) EVERY 3 MONTHS. Replace filter(s) when necessary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, pernlanent filters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER
MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid prolonged shutdown of your unit while a filter is drying, you
should have an extra filter on hand. This allows you to rotate between the two with minimal downtime %r your com%rt system. Extra filters may
be purchased /born your dealer.
