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°For
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
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 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).
STANDBY lamp
•
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.
Power failure
during operation
•
In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically after five minutes.
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.
