NOTE: DO NOT OVER OIL
FILTER CARE
Inspect the air filter(s) at least once a month. If they are dirty, wash reusable filters with a mild detergent per manu- facturer's recommendations. Replace disposable filters with new filters.
Install the clean filters with air flow" arrow in the same direction as the air flow in your duct. Filters should be clean to assure maximum efficiency and adequate air circulation. Drapes, furniture or other obstructions blocking your supply and return air grilles will also decrease efficiency.
OUTDOOR UNIT FINISH
If you wish to maintain the finish of the outdoor unit, it can be polished with car wax. It is recommended the unit be cleaned with soap and water prior to waxing.
