Special Remarks
‘‘DRY’’ ( ) Operation
How it works?
•
If the room temperature is higher than the setting temperature, the
air conditioner operates in the same way as during cooling
operation. When the room temperature approaches the setting
temperature, the air conditioner switches to DRY operation and the
indoor fans operate irregularly.
In addition, the outdoor unit continues operation at lowered
capacity, and repeats the cycle of operation and shutdown if the
room temperature drops further.
If the outdoor unit stops when the room temperature is less than
20 °C, the indoor fan also stops. If the room temperature is less than
15 °C, both the indoor fan and outdoor unit stop.
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
in conjunction 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. Heating operation restarts
after several minutes. (This interval will vary slightly depending
upon the outdoor temperature and the way in which frost forms).
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 control unit
•
The remote control unit sends the setting condition to the air
conditioner regularly at five minute intervals.
