• Type of operation: Fan operation
mode.(Refer to page 17.)
• This will dry out the internal mechanisms.
Helpful information
The air filters and your electiric bill.
If the air filters become clogged with dust, the
cooling capacity will drop, and 6% of the
electricity used to operate the air conditioner will
be wasted.

(Refer to page 21 for cleaning it.)
Check that the air inlet and outlet of
the indoor/outdoor unit are not
blocked.

connected correctly. It may be
connect to the indoor unit side.
Do not overcool the room.
This is not good for the health
and wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine

open them and ventilate the
room now and then.
