DAILY INSPECTION & MAINTENANCE
Empty the Drain Tank
To empty the drain tank, refer to instructions on page 24.
Clean the Air Filters
Clean the air filters once a week. If the unit is used in a dusty environment, more
frequent cleaning may be required. A dirty air filter can reduce air output resulting
in a decrease in the cooling capacity.
Filter Removal Method
1. Turn the unit off by pressing the COOL ON/OFF button.
If a program is running, you must first press the PROGRAM RUN button.
2. Remove the two air filters.
Note: To remove the filter 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 wire frame.
Filter Cleaning Method
1. Remove dust from the element with a vacuum
cleaner, or rinse in cold or lukewarm water. If the
element is extremely dirty, wash with a neutral
detergent.
2. After the element has been cleaned, rinse with
clean running water, allow to dry, then reinstall.
