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 qualied 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.

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.
Durin
g the healthy dehumidification fu nc ti on, t he airflow volume i s
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.

Operating Instructions
Artificial intelligence function judges and operates the set temperature
and fan level based room temperature to provide pleasant environment
to the user. Artificial intelligence can be categorized largely into cool and
dehumidifier artificial intelligence. If the user selects artificial intelligence
function during cool operation, it operates in cool artificial intelligence.
if the user selects during dehumidifier operation, it operates in dehumidifier
artificial intelligence.

Jet Cool/Heat Operation
NEO PLASMA Purification Operation (Optional)
During auto clean function, only START/STOP BUTTON, PLASMA BUTTON and AUTO CLEAN BUTTON
can be used.
During auto clean function, moistures left in indoor units after cooling operation or healthy dehumidification
operation can be removed.
1. Press the AUTO CLEAN BUTTON to activate this function.
2. 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.
3. This dries up any remains of moisture & cleans the unit internally.
4. If you press AUTO CLEAN BUTTON again during operation, this function is
cancelled.
Auto Clean (Optional)
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.
Plasma filter is a technology developed by LG to get rid of microscopic
contaminants in the intake air by generating a plasma of high charge electrons.
This plasma kills and destroys the contaminants completely to provide clean and
hygienic air.
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.
• 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.
Plasma purification can be started by pressing the PLASMA BUTTON on the remote controller.
Repressing it will deactivate the operation.
This feature can be used in any operation mode and any fan speed can be used while
plasma filter is functioning.
