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 automatically runs at lower speed for providing a comfortable breeze.

•‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F 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 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 a 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 in operation.

Cooling () operation

•Sometimes the indoor unit may not get to the set fan speed such as LOW under cool operation at very low outdoor temperatures due to the indoor unit being protected from ice or frost.

Power failure during operation

•In the event of power failure, the unit will stop. When the power is resumed, the unit will restart automatically in approximately

15 minutes by the remote controller.

Clicking Sound

Clicking sound is heard from the air conditioner

•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.

Remote Controller

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