Special Remarks
•
In the event of power failure, the unit will stop. Though the power is
resumed, the unit will not restart automatically.
Press the ON/OFF operation button and restart the unit again.

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.
