Electrical Safety

▲ WARNING

• This appliance must be properly grounded.
To minimize the risk of electric shock, you must alway plug into a grounded outlet.
- Do not cut or remove the grounding prong from the power plug.
- Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated, and the wall receptacle is grounded through the house wiring.
- If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and circuit checked by a qualified electrician.

Temporary Use of an Adapter

We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections, use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection.

To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage.

▲ WARNING

- Never use the appliance with a broken adapter.

Temporary Use of an Extension Cord

We strongly discourage the use of an extension cord due to potential safety hazards.

▲ WARNING

This appliance should be installed in accordance with national wiring regulations. This guide acts as a guide to help to explain product features.

Simple line drawing of a device interface with Wi-Fi, water drop, and battery symbols (no text or labels)

During Healthy Dehumidification Operation

☐If you select the dehumidification mode on the OPERATION MODE SELECTION BUTTON, the product starts to run the dehumidification function. It automatically sets the room temperature and airflow volume to the best condition for dehumidification, based on the sensed current room temperature.

In this case, however, the setting temperature is not displayed on the remote controller and you are not able to control the room temperature either.

☐During the healthy dehumidification function, the airflow volume is automatically set according to the optimization algorithm responding to the current room temperature status, so that the room condition is kept healthy and comfortable even in the very humid season.

To run the healthy dehumidification mode follow steps 1, and 2 and 4 (See operation mode)

Auto Operation (Cooling Only Model)

Diagram showing Wi-Fi interface with temperature and alarm icons above a screen

In this operation mode the actual setting temperature and the fan speed are automatically set by the electronic control logic based on the current room temperature. If you feel hot or cold press the temperature setting buttons respectively for more cooling or heating effect.

NOTE : You cannot set the actual setting temperature and the indoor fan speed in this operation mode. But you can use the Chaos swing in this operation. If the system is not operating as desired, switch manually to another mode.

To run the auto operation follow steps 1, and 2. (See operation mode)

Auto Changeover Operation (Heat Pump Model)

A 22°C

Auto operation basically is heating or cooling function of the air conditioner.

But during this operation the controller changes the operation mode automatically to keep the temperature within ±2^ with respect to the setting temperature.

To run this operation follow steps 1, 2, 3, and 4. (See operation mode)

Jet Cool/Heat Operation

P0 JET

Jet cool function can be used to cool the room quickly in hot summer. When this function is turned on, the air conditioner runs in cooling operation mode with super high fan speed and 18^ C setting temperature for 30 minutes for fast and effective cooling.

Similarly, jet heat function (available only in some models) warms up the room quickly by operating at super high fan speed and 30^ C setting temperature for 60 minutes.

You can activate this operation by pressing the JET COOL BUTTON.

To change from jet cool mode to high fan speed cooling mode, press the JET COOL BUTTON or INIDOOR FAN SPEED SELECTOR BUTTON or the ROOM TERPERATURE SETTING BUTTON again.

NOTE

4. If you press AUTO CLEAN BUTTON again during operation, this function is cancelled.

NOTE

During auto clean function, only START/STOP BUTTON, PLASMA BUTTON and AUTO CLEAN BUTTON can be used.

Energy-Saving Cooling Mode (Optional)

Energy-saving cooling mode can save energy in cooling and healthy dehumidification operation, because it can operate efficiently by setting body-adaptation time according to the change of time and temperature and adjusting automatically desired temperature.

1. Press the START/STOP BUTTON to start the unit.
2. Open the door on the remote controller. Select cooling operation or healthy dehumidification operation.
3. Press the ENERGY-SAVING COOLING MODE BUTTON.
