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.

➀ Turn the unit off by pressing the COOL ON/OFF button. If a pro-

gram is running, you must first press the Program “RUN” button.

➁ Remove 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.
