obstructed, the unit will not work well, and may be damaged.

blinds or curtains. If the walls and ceiling of the room are
warmed by the sun, it will take longer to cool the room.
Do
● Always try to keep the air filter clean. (Refer to "Care and
Cleaning.") A clogged filter will impair the performance of the
unit.
● To prevent conditioned air from escaping, keep windows,
doors and any other openings closed.
