Special Remarks

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.
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. Heating operation restarts
after several minutes. (This interval will vary slightly depending
upon the outdoor temperature and the way in which frost forms).
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.
