SPECIAL REMARKS

‘‘DRY’’ Operation

How it works • Once the room temperature reaches the level that was set, the unit repeats the cycle of

turning on and off automatically.

• In order to prevent the humidity in the room from rising again, the indoor fan also turns off

when the unit stops operating.

• The fan speed is set to ‘‘LO.’’ automatically, and cannot be adjusted.

• ‘‘DRY’’ operation is not possible if the outdoor temperature is 15 °C or less.

Heating Operation

Heating performance • Because this appliance heats a room by utilizing the heat of the outside air (heat pump

system), the heating efficiency will fall off when the outdoor temperature is very low. If

sufficient heat cannot be obtained with this heat pump, use another heating appliance in

conjunction with this unit.

Defrosting • When the outdoor temperature is low, frost or ice may form on the outdoor heat exchanger

coil, reducing the heating performance. When this happens, a microcomputer-controlled

defrosting system operates. At the same time, the fan on the indoor unit stops (or runs at

very low speed in some cases) and the ‘‘STANDBY’’ indicator appears on the display until

defrosting is completed. Heating operation then restarts after several minutes. (This interval

will vary slightly depending upon the outdoor temperature and the way in which frost forms.)

(standby) on the

• For several minutes after the start of heating operation, the indoor fan will not start running

display

(or it will run at very low speed in some cases) until the indoor heat exchanger coil has

warmed up sufficiently. This is because a cold draft prevention system is operating. During

this period, the ‘‘ ’’ (standby) indicator remains displayed.

• ‘‘ ’’ (standby) remains displayed during defrosting or when the compressor has been

turned off (or when the unit is running at very low speed) by the thermostat when the

system is in the heating mode.

• Upon completion of defrosting and when the compressor is turned on again, ‘‘ ’’

(standby) will turn off automatically as heating operation resumes.

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 the power is restored) using the same settings before the power was cut off.

CARE AND CLEANING

1. For safety, be sure to turn the air conditioner off and also to disconnect the power

before cleaning.

2. Do not pour water on the indoor unit to clean it. This will damage the internal

components and cause an electric shock hazard.

Air intake and outlet side

Clean the air intake and outlet side of the indoor unit with a vacuum cleaner brush, or wipe

(Indoor unit)

them with a clean, soft cloth.

If these parts are stained, use a clean cloth moistened with water. When cleaning the air outlet

side, be careful not to force the vanes out of place.

1. Never use solvents or harsh chemicals when cleaning the indoor unit. Do not wipe

plastic parts using very hot water.

2. Some metal edges and the fins are sharp and may cause injury if handled

improperly; be especially careful when you clean these parts.

3. The internal coil and other components of the outdoor unit must be cleaned

periodically. Consult your dealer or service center.
