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.

■ 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. (See Section "■ 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.
