If your air conditioner still does not work properly although you checked the points as described above, fi rst 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

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 fi lter clean. (Refer to "CARE AND CLEANING".) A clogged fi lter 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.
