DAILY INSPECTION & MAINTENANCE
Emptying the Drain Tank
To empty the drain tank, refer to instructions on page 14.
Cleaning the Air Filters
Clean the air filters once a week. If the unit is used in a dusty environ- ment, more frequent cleaning may be required.
A dirty air filter reduces air output resulting in a decrease of the cooling capacity.
➀Turn the unit off by pressing the COOL ON/OFF button. If a pro- gram is running, you must first press the Program “RUN” button.
➁Remove the two air filters.
NOTE: To remove the filters from the Office Pro models, open the front panel and side panel filter doors. On the front panel door, carefully remove the filter retainer from its clips by pulling on the retainer at those two points. On the side panel door, carefully remove the filter element from the Velcro® attachment points.
