Special Remarks

• Once the room temperature reaches the level that was set, the unit's operation
frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower speed for
providing a comfortable breeze.
• ''DRY'' operation is not possible if the indoor temperature is 59 °F 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 together 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 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.)
• 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 15 minutes by the remote control unit.
• 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.
