V. FUNCTIONS

- Auto-Restart

If the unit loses power, it will automatically restart with the prior settings once power has been restored.

- Wi-Fi Control

Wi-Fi control allows you to control your air conditioner using your mobile phone and a Wi-Fi connection.

For the USB device access, replacement, maintenance operations must be carried out by professional staff.

• Louver Angle Memory

When turning on your unit, the louver will automatically resume its former angle.

• Refrigerant Leakage Detection

The indoor unit will automatically display "EC" or "ELOC" when it detects refrigerant leakage.

- Setting Angle Of Air Flow

Setting vertical angle of air flow

While the unit is on, use the SWING /DIRECT button to set the direction (vertical angle) of airflow.

AUTO operation

When you set the air conditioner in AUTO mode, it will automatically select cooling, heating (cooling/heating models only), or fan only operation depending on set temperature and the room temperature.

The air conditioner will control room temperature automatically to the temperature point you set.

If you feel uncomfortable in the AUTO mode, you can set your desired temperature.

DRYING operation

The temperature is regulated while dehumidifying by repeating turning on and off of the cooling operation or fan only. The fan speed is LOW.

HEATING operation

This air conditioner operates on the heat-pump principle, absorbing heat from air outdoors and transferring that heat to the indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that the heating performance is insufficient, we recommend you to use this air conditioner in conjunction with other kinds of heating appliance.

Setting horizontal angle of air flow

The horizontal angle of the airflow must be set manually. Grip the deflector rod and manually adjust it to your preferred direction.

For some units, the horizontal angle of the airflow can be set by remote control. please refer to the Remote Control Manual.

Note on louver angles

When using COOL or DRY mode, do not set louver at too vertical an angle for long periods of time. This can cause water to condense on the louver blade, which will drop on your floor or furnishings.

When using COOL or HEAT mode, setting the louver at too vertical an angle can reduce the performance of the unit due to restricted air flow.

Do not move louver by hand. This will cause the louver to become out of sync. If this occurs, turn off the unit and unplug it for a few seconds, then restart the unit. This will reset the louver.

Deflector rod

CAUTION

Do not put your fingers in or near the blower and suction side of the unit. The high-speed fan inside the unit may cause injury.
