		malfunctioning.
		(The inspection mark	and the letters E, F,
		H, L, P in combination with numbers appear
		on the LCD of the wired remote control unit.)

Compressor runs but soon stops	1. Obstruction in front of condenser coil			1. Remove obstruction

Poor cooling (or heating) performance	1. Dirty or clogged air filter.			1.	Clean air filter to improve the airflow.
	2.	Heat source or many people in room.		2.	Eliminate heat source if possible.
	3. Doors and/or windows are open.			3. Shut them to keep the heat (or cold) out.
	4.	Obstacle near air intake or air discharge port.		4.	Remove it to ensure good airflow.
	5.	Thermostat is set too high for cooling		5.	Set the temperature lower (or higher).
		(or too low for heating).
	6.	(Defrosting system does not work.)		6.	(Consult your dealer.)

■Tips for Energy Saving

Avoid

Do

•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.

•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.
