If your air conditioner still does not work properly although you checked the points as described above, first stop the operation and

turn off the power switch. Then contact your dealer and report the serial number and symptom. Never repair your air conditioner

by yourself since it is very dangerous for you to do so. You also report if the inspection mark and the letters E, F, H, L, P in

combination with the numbers appear on the LCD of the remote control unit.

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 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.

• 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 cut off, the unit will automatically resume operation once power is restored using the

same settings before the power was interrupted.
