TIPS FOR ENERGY SAVING

• Do not block neither the air intake nor the air outlet. It may cause less performance,
and may lead malfunctions.
• Do not let direct sunlight into the room. Use sunshades, blinds or curtains. If the walls, and
floor and the 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 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.
