Electrical Safety
Electrical Safety
•This appliance must be properly grounded.
To minimize the risk of electric shock, you must alway plug into a grounded oulet.
•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.
• 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. For temporary situations, use only CSA certified and UL listed 3-wire grounded extension cords, rated 15 A, 125 V.
This appliance should be installed in accordance with national wiring regulations. This guide acts as a guide to help to explain product features.

Operating Instructions
Healthy
Dehumidification
Operation
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.
Air
Circulation
Operation
NOTE
This operation circulates the air without cooling or heating. It can be activated by pressing the OPERATION MODE SELECTION BUTTON. Once the air circulation is activated you can select the air speed by pressing the INDOOR FAN SPEED SELECTOR BUTTON.
CHAOS Air economizes power consumption and prevents overcooling. The fan speed is automatically changed from high to low or vice versa, depending on the ambient temperature.
Auto
Operation
(Cooling
Only
Model)
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.
Auto
Changeover
Operation
(Heat
Pump
Model)
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°C with respect to the setting temperature.

Operating Instructions
Jet
Cool/Heat
Operation
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
•Jet cool function cannot be activated during heating or auto changeover operations.
•In case of Inverter, Art Cool and Art Cool Wide(non-Deluxe) model, you can use jet heat function by pressing JET COOL BUTTON for heating operation.
•Art Cool and Art Cool Wide models close the side discharges during jet cool/heat operation, for strong cooling and heating.
Auto
Clean
Operation
During auto clean function, moistures left in indoor units after cooling operation or healthy dehumidification operation can be removed.
• Press the AUTO CLEAN BUTTON to activate this function.
• Now whenever the unit is turned off, the indoor fan is still running for about 30 minutes internally without cooling or dehumidification operation. Also the louver is closed.
•This dries up any remains of moisture & cleans the unit internally.
•If you press AUTO CLEAN BUTTON again during operation, this function is
NOTE cancelled.
During auto clean function, only ON/OFF BUTTON, PLASMA BUTTON and AUTO CLEAN BUTTON can be used.

This plasma kills and destroys the contaminants completely to provide clean and hygienic air.
Plasma purification can be started by pressing the PLASMA BUTTON on the remote controller. Repressing it will deactivate the operation.
NOTE
This feature can be used in any operation mode and any fan speed can be used while plasma filter is functioning.
