• Plasma (Three wave-like icons): The function illustrates its dynamic mode by using a multiple lighting system.

• Power Display (88): Indicates the setting temperature and operation mode (Cooling, heating, auto operation, dehumidification mode).

*Hot start operation: Stops the indoor fan in heating operation for a few minutes to prevent cold air from blowing out from the unit.

*In defrost mode: The unit stops heating operation for a few minutes to remove the formation of ice on the heat exchanger coils to maintain efficiency.

The optional wireless remote controller for your LG LRNU07GSEB0 has the following functions:

When handling the remote controller, please observe the following:

• Aim at the signal receptor on the unit to operate. The 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.

• Do not drop or throw the remote controller.

• Do not place the remote controller in a location exposed to direct sunlight, or near a heating unit or other heat source.

• Block strong light (e.g., electronic quick start, ELBA, inverter type fluorescent lamp) over the signal receptor with a curtain to prevent abnormal operation.

• Replace all batteries in the remote control with new ones of the same type. Do not mix old and new batteries, or different types of batteries.

• Do not recharge or disassemble the batteries. Do not dispose of batteries in a fire.

• 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.

Before performing any maintenance, turn off the main power to the system. Never use water hotter than 40°C or volatile substances like gasoline or benzene, as they could damage the surfaces of the air conditioner.

Air Filters (Clean every 2 weeks or more often if necessary):

1. Open the front panel to access the filters. There are two methods depending on your model type:

• Type 1: Open the upside of the panel and lift it up. The hooks of the panel will come off. Remove the air filters.

• Type 2: Open the front panel. Then pull the filter tab slightly forward to remove the air filter.

2. Clean the filters with a vacuum cleaner or warm soapy water.

3. If dirt is not easily removed, wash with a solution of detergent in lukewarm water.

4. Dry well in the shade after washing.

5. Reinstall the filters back in place.

Plasma and Deodorizer Filters (Clean plasma filters every 3 months or more often if necessary):

1. After removing the air filter, you can access the plasma and deodorizer filters.

2. Remove the plasma and deodorizer filter by slightly pulling forward.

3. To clean the plasma filter, use a vacuum cleaner. If it is very dirty, wash it with water and dry well in the shade before reinstalling.

4. To clean the deodorizer filters, expose them to direct sunlight for 2 hours, then insert them back into their original position.

CAUTION: Do not touch the plasma filter within 10 seconds after opening the inlet grille, as it may cause an electric shock.

If you are not going to use your LG LRNU07GSEB0 for an extended period, follow these steps to prepare it:

1. Operate the air conditioner in Fan operation mode for 2 to 3 hours. This will dry out the internal mechanisms.

2. Turn off the circuit breaker. Dirt may collect and cause a fire if left on.

When you are ready to use the air conditioner again, perform the following checks:

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

2. Check that the air inlet and outlet of the indoor and outdoor units are not blocked.

3. Check that the ground wire is connected correctly.

To get the most efficient performance from your LG LRNU07GSEB0, follow these tips:

• Do not overcool the room. 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 air conditioner is in operation.

• Keep the room temperature uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.

• Make sure that doors and windows are shut tight. Avoid opening them as much as possible to keep the cool air in the room.

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

• Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

If your LG LRNU07GSEB0 does not operate, check the following:

• Have you made a mistake in the timer operation?

• Has the fuse blown or has the circuit breaker been tripped?

If you notice a peculiar odor, check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room. The air conditioner circulates the existing air and does not typically generate odors on its own.

It may seem that water is leaking, but this is likely condensation. Condensation occurs when the airflow from the air conditioner cools the warm room air. This is a normal part of the cooling process.

This is normal. The delay is a protective feature of the mechanism. You should wait about three minutes, and the operation will begin.

If your LG LRNU07GSEB0 is not cooling or heating effectively, please check these points:

• Is the air filter dirty? Refer to the air filter cleaning instructions.

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

• Has the temperature been set incorrectly?

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

The sounds you hear during operation are likely normal. Here’s what they could be:

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

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

This sound is generated by the expansion and constriction of the front panel and other plastic parts due to changes in temperature. This is a normal sound.

If the remote control display is faint or has no display at all, check the batteries:

• Are the batteries depleted? Try replacing them with new ones.

• Are the batteries inserted in the opposite (+) and (-) directions? Check the battery orientation.

The filter sign lamp is a reminder to clean the air filter. After cleaning the filter, you need to reset the reminder. To do this, press the Timer button and the down arrow (▼) button on the wired remote controller at the same time for 3 seconds.

No, the indoor unit is not water resistant and should not be exposed to excess water. The outdoor side of the appliance is water resistant.
