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.
During DRY operation, the fan speed is automatically set to LOW or
VERY LOW; the fan speed then switches back and forth between
LOW (for 20 seconds) and VERY LOW (for 10 seconds).
“DRY” operation is not possible if the indoor temperature is 59
°
F or less.

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 in conjunction with it.
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 STANDBY lamp remains lit 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).
For several minutes after the start of heating operation, the indoor fan will not start running until the indoor heat exchanger coil has warmed up sufficiently. This is because the COLD DRAFT
PREVENTION SYSTEM is operating. During this period, the
STANDBY lamp remains lit.
The STANDBY lamp also remains lit during defrosting or when the compressor has been turned off by the thermostat when the system is in the heating mode.
Upon completion of defrosting and when the compressor is turned on again, for heating operation, the STANDBY lamp will go off automatically.

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.
