consult your dealer or service center.
The frequency with which the filter should be cleaned depends on the
environment in which the unit is used.

filter, wash the filter in lukewarm, soapy water, rinse it in clean water, and
dry it.

If the walls and ceiling of the room are warmed by the sun, it will take
longer to cool the room.

other openings closed.
