NOTE

17
Special Remarks
How it works? • Once the room temperature reaches the level that was set, the unit’s
operation frequency is changed automatically.
• During DRY operation, the fan speed is automatically runs at lower speed
for providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 15 °C or less.
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 together 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 OPERATION lamp lights up red and orange
alternately 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.)
Cold draft prevention • For several minutes after the start of heating operation, the indoor fan runs
at lower speed until the indoor heat exchanger coil has warmed up
sufficiently. However, the fan may remain stopped when the room
temperature is low. This is because the COLD DRAFT PREVENTION
SYSTEM is operating.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically within five minutes by the
remote control unit.
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.
• The remote control unit sends the setting condition to the air conditioner
regularly at five minute intervals.
