During heating operation, frost might occur onthe outdoor unit and decrease the heating capacity. In that case,the system automatically switches to defrosting operation toremove the frost. During defrosting operation, hot air is NOTblown from the indoor unit.▪ Humidity sensor. Control the humidity by decreasing thehumidity during cooling process.4.3.1 To start/stop operation and to set thetemperature: Unit is operating.: Operation mode = Automatic: Operation mode = Drying: Operation mode = Cooling: Operation mode = Heating: Operation mode = Fan only: Shows the set temperature.1 Press one or more times to select the operation mode.Result: The mode will be set as follows:2 Press to start operation.Result: and the selected mode are displayed on the LCD.3 Press or one or more times to lower or raise thetemperature.CoolingoperationHeatingoperationAutomaticoperationDrying or Fanonly operation18~32°C 10~30°C 18~30°C —Note: When using drying or fan only mode, you cannot adjust thetemperature.4 Press to stop operation.Result: disappears from the LCD.

Adjust the airflow direction as desired.What. The system directs the airflow differently, depending on theuser selection (swinging or fixed position). It does so by movinghorizontal blades (flaps) or vertical blades (louvers).Setting Airflow directionVertical automaticswingMoves up and down.Horizontalautomatic swingMoves from side to side.+ 3-D airflowdirectionMoves simultaneously up and down andfrom side to side[—] Stays in a fixed position.CAUTION▪ ALWAYS use a user interface to adjust the position ofthe flaps and louvers. When the flaps and louvers areswinging and you move them forcibly by hand, themechanism will break.▪ Be careful when adjusting the flaps and louvers. Insidethe air outlet, a fan is rotating at high speed.Note: The movable range of the flap varies according to theoperation mode. The flap will stop at the upper position when theairflow rate is changed to low during the up and down swing setting.aba Flap range in cooling or drying operationb Flap range in heating or fan only operationTo adjust vertical airflow direction1 Press .Result: appears on the LCD.
