Tips for Energy Saving
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.
•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.
•Toprevent 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 interrupted the unit will
automatically resume operation (once the power is restored) with the same
settings that were in effect before the power was interrupted.
