Operation Details
1) Cooling Mode Operation
Cooling in operation according to Remote Control setting.
• When the compressor is stopped by Power Switch or Remote Control, it restarts after 3 minutes when the Power
Switch or Remote Control is turned ON.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3
minutes.
• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is below the
compressor ON temperature.
• When the compressor, outdoor fan motor & indoor fan motor are simultaneously started, the indoor fan motor will
operate 1.6 second later.
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake
air and indoor heat exchanger is 2.5˚C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid).
∆ T = Intake air temperature – Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
Time Delay Safety Control (3 minutes)
7 minutes Time Saved Control
Starting Current Control
Anti-Freezing Control
• If the temperature of the indoor heat exchanger
falls continously below 2°C for 4 minutes or more,
the compressor turns off to protect the indoor heat
exchanger from freezing. The fan speed setting
remains the same.
• Compressor recommences when the indoor heat
exchanger temperature rises to 10°C (Recovery).
*3 minutes waiting of Time Delay Safety Control
is valid for Cooling Operation.

Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during cooling operation.
• Fan speed rotates in the range of Hi to Me.
• Deodorizing Control.
Operation Details
Cooling Operation Time Diagram
* 1 Fan Speed is Hi until the compressor stops (when the room temperature reaches
setting temperature).
* 2 Fan Speed is Me after the compressor restarts.
* SLo: Indoor Fan rotates at 4 second intervals at low speed.

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 will operate and stop at 4-second intervals at low speed.
• The operation will be switched on and off for up to 10 minutes “ON” and 6 minutes “OFF”. Once Soft Dry opera-
tion is turned off, it stops for 6 minutes.
• Once the compressor stops, it will not start for 3 minutes during Cooling operation.
• Same as Starting Current Control for Cooling Mode operation.
• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during
compressor stops.)
• Same as Compressor Reverse Rotation Protection 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 and Lo speed.
• Deodorizing Control.
* SLo: Indoor Fan rotates at 4-second intervals at low speed.
