work.)
• Do not block the air intake and outlet of the unit. If either is obstructed, the
unit will not work well, and may be damaged.
• Do not let direct sunlight into the room. Use sunshades, 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.
