■ 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.
NOTE
Should the power fail while the unit is running
If the power supply for this unit is temporarily cut off, the unit will
automatically resume operation once power is restored using
the same settings before the power was interrupted.
