Symptom
Air conditioner does not run at
all although power is turned
on.
Poor cooling or heating
performance
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
combination with the numbers appear on the LCD of the remote controller.
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.
