Special Remarks
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 15 °C
•
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 PREVEN-
TION 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.
In the event of power failure, the unit will stop. When the power is
•
resumed, the unit will restart automatically after three minutes.
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 disap-
pear.
The remote control unit sends the setting condition to the air
•
conditioner regularly at three minute intervals.
