NOTE
The frequency with which the filter should be cleaned depends on the environment in which the
unit is used.
Clean the filter frequently for best performance in the area of dusty or oil spots regardless of filter
status.
<How to clean the filter>
1. Remove the air filter from the air intake grille.
2. Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter, wash the filter in
lukewarm, soapy water, rinse it in clean water, and dry it.
<How to remove the filter>
4-Way Cassette 60 × 60 Type (Y3):

reattach the two bolt screws after cleaning.)
2. Slide the latches of the air intake grille in the direction of the inside to open the grille.
3. The air intake grille opens downward.
CAUTION
● When cleaning the air filter, never remove the safety strap. If it is necessary to remove
it for servicing and maintenance inside, be sure to reinstall the safety strap securely
(hook on the grille side) after the work.
● When the filter has been removed, rotating parts (such as the fan), electrically charged
areas, etc. will be exposed in the unit’s opening. Bear in mind the dangers that these
parts and areas pose, and proceed with the work carefully.
4. Push the bottom of the air filter up and pull it toward you. The air filter will be disengaged.
