<h3 class="sub-tit">Auto drying function</h3>
<p>
When you stop the cooling or dehumidification operations, the drying function will begin automatically.<br/>
When the automatic drying function begins, the air conditioner operates in air blowing status for a set
period of time in order to remove any moisture remaining in the evaporator.<br/>
Moisture produces a favorable habitat condition for mold and bacteria, so, it is recommended to set and use
the automatic drying function for a clean air conditioner.<br/>
The inside drying status may vary depending on the temperature of indoor air and humidity conditions.
