Take care to ensure that nobody could step on or fall onto the outdoor unit. This could result in personal injury and product damage.

Always check for gas (refrigerant) leakage after installation or repair of the product. Low refrigerant levels may cause failure of the product.

Install the drain hose to ensure that water is drained away properly. A bad connection may cause water leakage.

Keep level even when installing the product to avoid vibration or water leakage.

Do not install the product where the noise or hot air from the outdoor unit could damage the neighborhoods, as it may cause a problem for your neighbors.

Do not install the product where it will be exposed to sea wind (salt spray) directly. It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

Use two or more people to lift and transport the product to avoid personal injury.

No, do not expose the skin directly to cool air for long periods of time (don’t sit in the draft). This could harm your health.

No, do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.

No, do not block the inlet or outlet of airflow. It may cause product failure.

Use a soft cloth to clean. Do not use harsh detergents, solvents, etc., as there is risk of fire, electric shock, or damage to the plastic parts of the product.

No, do not touch the metal parts of the product when removing the air filter. They are very sharp, and there is risk of personal injury.

No, do not step on or put anything on the outdoor units. There is risk of personal injury and failure of the product.

Always insert the filter securely. Clean the filter every two weeks or more often if necessary. A dirty filter reduces the efficiency of the air conditioner and could cause product malfunction or damage.

No, do not insert hands or other objects through the air inlet or outlet while the product is operated. There are sharp and moving parts that could cause personal injury.

No, do not drink the water drained from the product. It is not sanitary and could cause serious health issues.

If the liquid from the batteries gets onto your skin or clothes, wash it well with clean water. Do not use the remote if the batteries have leaked. The chemicals in batteries could cause burns or other health hazards.

1. Contact an installation specialist for installation.

2. Use a dedicated circuit.

No, being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

Yes, due to the possibility of oxygen deficiency, ventilate the room when the LG LRNU24GS3C0 is used together with stoves or other heating devices.

No, do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.

Be sure that there are no obstructions between the remote controller and the signal receptor.

No, do not drop or throw the remote controller.

Do not place the remote controller 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 etc. so as to prevent abnormal operation (e.g., electronic quick start, ELBA, inverter type fluorescent lamp).

Before performing any maintenance, turn off the main power to the system. Never use any of the followings:

1. Water hotter than 40°C, as it could cause deformation and/or discoloration.

2. Volatile substances, as they could damage the surfaces of the air conditioner.

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

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

Remove the deodorizer filters behind the air filter and expose them to direct sunlight for 2 hours. Then insert these filters into their original position.

To remove filters from the LG LRNU24GS3C0 (Type 1):

1. Open the upside of the panel and lift it up. The hooks of the panel will come off.

2. Remove the air filters.

3. Pull out the plasma filter.

To remove filters from the LG LRNU24GS3C0 (Type 2):

1. Open the front panel.

2. Pull the filter tab slightly forward to remove the air filter.

3. After removing the air filter, remove the plasma and deodorizer filter by slightly pulling forward.

No, do not touch the plasma filter within 10 seconds after opening the inlet grille, as it may cause an electric shock.

Operate the LG LRNU24GS3C0 at the following settings for 2 to 3 hours:

1. Type of operation: Fan operation mode.

This will dry out the internal mechanisms.

Turn off the breaker after preparing the LG LRNU24GS3C0 for a long period of disuse.

Turn off the breaker when the LG LRNU24GS3C0 is not going to be used for a long time. Dirt may collect and may cause a fire.

If the air filters of the LG LRNU24GS3C0 become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

Clean the air filter and install it in the indoor unit.

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

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

No, do not overcool the room. This is not good for health and wastes electricity.

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

Adjust the vertical and horizontal airflow direction 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.

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

Yes, ventilate the room occasionally. Since windows are kept closed, 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.

Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room.

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

This is the protector of the mechanism. Wait about three minutes, and operation will begin.

1. Is the air filter dirty? See air filter cleaning instructions.

2. The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down.

3. Has the temperature been set incorrectly?

4. Are the indoor unit’s air inlet or outlet vents obstructed?

A noise that sounds like water flowing is the sound of freon flowing inside the air conditioner unit.

A noise that sounds like compressed air releasing into the atmosphere is the sound of dehumidifying water being processed inside the air conditioning unit.

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

After cleaning the filter, press the Timer button and the button of the wired remote controller at the same time for 3 seconds.

1. Are the batteries depleted?

2. Are the batteries inserted in the opposite (+) and (-) directions?

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