CHECK BEFORE REQUIRING SERVICES
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

unit.
• To prevent conditioned air from escaping, keep windows, doors and any other openings closed.
