Aim at the signal receptor on the wired remote controller so as to operate your LG LRNU24GS3M0.

The remote control signal can be received at a distance of up to about 7m.

Be sure that there are no obstructions between the remote controller and the signal receptor of your LG LRNU24GS3M0.

Do not drop or throw the remote controller for your LG LRNU24GS3M0.

Do not place the remote controller for your LG LRNU24GS3M0 in a location exposed to direct sunlight, or near the heating unit, or any other heat source.

Block a strong light over the signal receptor with a curtain or other means to prevent abnormal operation (e.g., from electronic quick start, ELBA, inverter type fluorescent lamps).

Before performing any maintenance, turn off the main power to the LG LRNU24GS3M0 system.

Never use water hotter than 40°C or volatile substances when cleaning your LG LRNU24GS3M0. Water hotter than 40°C could cause deformation and/or discoloration, and volatile substances could damage the surfaces of the air conditioner.

The air filters behind the front panel/grill of your LG LRNU24GS3M0 should be checked and cleaned once every 2 weeks or more often if necessary. To clean, use a vacuum cleaner or warm soapy water. If dirt is not easily removed, wash with a solution of detergent in lukewarm water. Dry the filters well in shade after washing and reinstall them.

The plasma filters behind the air filter of your LG LRNU24GS3M0 should be checked and cleaned once every 3 months or more often if necessary. To clean, use a vacuum cleaner. If it is dirty, wash it with water and dry well in shade, then install it back in place.

Remove the deodorizer filters behind the air filter of your LG LRNU24GS3M0 and expose them in direct sunlight for 2 hours. Then, insert these filters back into their original position.

For LG LRNU24GS3M0 (Art Cool Mirror Type 1), open the upside of the panel and lift it up. The hooks of the panel will come off. Then, remove the air filters and pull out the plasma filter.

For LG LRNU24GS3M0 (Art Cool Mirror Type 2), open the front panel. Then, pull the filter tab slightly forward to remove the air filter. After removing the air filter, remove the plasma and deodorizer filter by slightly pulling them forward.

Do not touch the plasma filter of your LG LRNU24GS3M0 within 10 seconds after opening the inlet grille, as it may cause an electric shock.

Operate the LG LRNU24GS3M0 air conditioner at the following settings for 2 to 3 hours:

• Type of operation: Fan operation mode.

This will dry out the internal mechanisms.

Turn off the breaker for the LG LRNU24GS3M0.

Turn off the breaker when the LG LRNU24GS3M0 air conditioner is not going to be used for a long time because dirt may collect and may cause a fire.

Clean the air filter of your LG LRNU24GS3M0 and install it in the indoor unit.

Check that the air inlet and outlet of the LG LRNU24GS3M0 indoor/outdoor unit are not blocked.

Check that the ground wire for your LG LRNU24GS3M0 is connected correctly. It may be connected to the indoor unit side.

If the air filters of your LG LRNU24GS3M0 become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

Do not overcool the room with your LG LRNU24GS3M0, as this is not good for your health and wastes electricity.

Keep blinds or curtains closed. Do not let direct sunshine enter the room when the LG LRNU24GS3M0 air conditioner is in operation.

Adjust the vertical and horizontal airflow direction of your LG LRNU24GS3M0 to ensure a uniform temperature in the room.

Make sure that the doors and windows are shut tight. Avoid opening doors and windows as much as possible to keep the cool air in the room when your LG LRNU24GS3M0 is operating.

Clean the air filter of your LG LRNU24GS3M0 regularly, at least once every two weeks. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects.

Since windows are kept closed when operating your LG LRNU24GS3M0, it is a good idea to open them and ventilate the room now and then.

Check if you have made a mistake in timer operation.

Check if the fuse has blown or if the circuit breaker has been tripped for your LG LRNU24GS3M0.

Check that the peculiar odor is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room, unrelated to the LG LRNU24GS3M0.

Condensation occurs when the airflow from the LG LRNU24GS3M0 air conditioner cools the warm room air.

This is due to the protector of the mechanism.

Wait about three minutes, and operation will begin.

Check if the air filter is dirty. Refer to the air filter cleaning instructions.

If the room was very hot when the LG LRNU24GS3M0 air conditioner was first turned on, allow time for it to cool down.

Check if the temperature has been set incorrectly.

Check if the indoor unit’s air inlet or outlet vents are obstructed.

This is the sound of freon flowing inside the LG LRNU24GS3M0 air conditioner unit.

This is the sound of the dehumidifying water being processed inside the LG LRNU24GS3M0 air conditioning unit.

This sound is generated by the expansion/constriction of the front panel, etc., due to changes in temperature within the LG LRNU24GS3M0.

After cleaning the filter, press the Timer button and the ‘down arrow’ button of the wired remote controller at the same time for 3 seconds to reset the indicator for your LG LRNU24GS3M0.

Check if the batteries are depleted.

Check if the batteries are inserted in the correct (+) and (-) directions.

The outdoor side of the LG LRNU24GS3M0 appliance is water resistant. The indoor side is not water resistant and should not be exposed to excess water.
