■ Tips for Energy Saving
Avoid
● 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.

Air filter
The air filter collects dust and other particles from the air and
should be cleaned at regular intervals as indicated in the table
below or when the filter indication ( ) on the display of the
remote control unit (wired type) shows that the filter needs
cleaning. If the filter gets blocked, the efficiency of the air
conditioner drops greatly.
