Special Remarks

‘‘DRY’’ ( ) Operation

How it works? • Once the room temperature reaches the level that was set, the unit’s operation frequency is changed automatically.

• During DRY operation, the fan speed is automatically runs at lower speed for providing a comfortable breeze.

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

Heating ( ) Operation

Heating performance

• Because this air conditioner heats a room by drawing in 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 air conditioner, use another heating appliance together with it.

Defrosting

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

 

exchanger coil, reducing heating performance. When this happens, a

 

microcomputer defrosting system operates. At the same time, the fan on

 

the indoor unit stops and the OPERATION lamp lights up red and orange

 

alternately until defrosting is completed. Heating operation restarts after

 

several minutes. (This interval will vary slightly depending upon the

 

outdoor temperature and the way in which frost forms.)

Cold draft prevention

• For several minutes after the start of heating operation, the indoor fan runs

 

at lower speed until the indoor heat exchanger coil has warmed up

 

sufficiently. However, the fan may remain stopped when the room

 

temperature is low. This is because the COLD DRAFT PREVENTION

 

SYSTEM is operating.

Power failure during operation

Clicking Sound

•In the event of power failure, the unit will stop. When the power is resumed, the unit will restart automatically within five minutes by the remote control unit.

Clicking sound is heard from the air conditioner

Remote Control Unit

•In heating or cooling operation, any plastic parts may expand or shrink due to a sudden temperature change. In this event, a clicking sound may occur. This is normal, and the sound will soon disappear.

•The remote control unit sends the setting condition to the air conditioner regularly at five minute intervals.
