6 Room Air Conditioner 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. 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. We strongly discourage the use of an extension cord due to potential safety hazards. Temporary Use of an Adapter Temporary Use of an Extension Cord This symbol alerts you to the risk of electric shock. This symbol alerts you to hazards that may cause harm to the air conditioner. This symbol indicates special notes. NOTE Symbols used in this Manual This appliance should be installed in accordance with national wiring regulations.

12 Room Air Conditioner 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. 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 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 Operation (Cooling Only Model) Auto Changeover Operation (Heat Pump Model) Healthy Dehumidification Operation 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. NOTE Air Circulation Operation
ENGLISH Owner's Manual 13 Operating Instructions Jet Cool/Heat Operation NEO PLASMA Purification Operation (Optional) ❏ During auto clean function, only ON/OFF BUTTON, PLASMA BUTTON and AUTO CLEAN BUTTON can be used.
