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 and warmed by the sun, it
will take longer to cool the room.
Do • Always try to keep the air filter clean.
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 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.
