NOTE Should the power fail while the unit is running
If the power supply for this unit is temporarily interrupted the unit will automatically

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 become 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. A clogged filter will impair the performance of the unit.
To prevent conditioned air from escaping, keep windows, doors and any other openings closed.
