Tips for Energy Saving
Avoid
Do
• 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.
• 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.
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.
