Operation Details

2) Soft Dry Mode Operation

• The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote

Control, and then Soft Dry operation will start.

• During Soft Dry operation, the Indoor Fan operates with SLo speed.
• Once room temperature reaches below Soft Dry OFF temperature. Indoor Fan, Compressor and Outdoor Fan

Stop for 6 minutes.

• Once the compressor stops, it will not start for 3 minutes during Cooling operation.

• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during

compressor stops.)

When Automatic Fan Speed is selected at Remote Control during Soft Dry Operation.
• Fan speed rotates at SLo speed.
• Deodorizing Control.
