Remote Control Sensor
Clean Filter
The Clean Filter LED lights up to notify you that the filter needs to be cleaned. After cleaning the filter, press Temp and together on the control panel to turn off the Clean Filter light.
- NOTE
- The filter reset must be done using the control panel, not the remote control.
- This feature is a reminder to clean the air filter for more efficient operation. The LED light turns on after 250 hours of operation.
- NOTE
- Auto Restart : If the air conditioner turns off due to a power outage, it will restart automatically once the power is restored, with the same settings as were set before the unit turned off.
- Energy Saver : The unit defaults to the Energy Saver mode each time the unit is switched on except in Fan mode or when power is restored after an electrical power outage.
- The remote control will not function properly if the AC infrared sensor is exposed to direct light or if there are obstacles between the remote controller and the air conditioner.

Remote Control

Energy Saver – In this mode the compressor and fan turn off when the set temperature is achieved. Approximately every 3 minutes the fan turns on to allow the unit sensor to accurately determine if more cooling is needed.
Cool – This mode is ideal on hot days to cool and dehumidify the room quickly. Use the Temp buttons to set the desired room temperature and use the Fan Speed button to set the desired fan circulation speed.
Fan – In this mode the fan circulates air but the compressor does not run. Use the Fan Speed button to set fan speed to High, Medium or Low. In this mode, you cannot adjust the set temperature.
Dry – This mode is ideal for rainy and damp days to dehumidify the room rather than cooling it significantly. Humidity is removed from the room by the combination of compressor operation and the fan speed fixed at Low. The compressor and fan turn off once the set temperature is reached. Fan speed cannot be adjusted in Dry mode.

Wireless Remote Control

Inserting Batteries

Push out the cover on the back of the remote control with your thumb.
With the plus and minus poles facing as marked, and insert two new AAA 1.5 V batteries.
Reattach the cover
- NOTE
- New batteries are supplied with the air conditioner for use in the remote control.
- Do not use a rechargeable battery. Make sure that the battery is new.
- In order to prevent discharge, remove the battery from the remote control if the air conditioner is not going to be used for an extended period of time.
- Keep the remote control away from extremely hot or humid places.
- To maintain optimal operation of the remote control, the remote sensor should not be exposed to direct sunlight.

Air Direction
Airflow can be adjusted by changing the direction of the air conditioner’s louvers.

Adjusting Horizontal Airflow Direction
The horizontal airflow is adjusted by moving the levers of the vertical louvers to the left or right.

Adjusting Vertical Airflow Direction
Touch the horizontal louvers to adjust the airflow up or down.

NOTE
When the weather is extremely hot, the unit may turn off automatically to protect the compressor.

Slinger Fan
This air conditioner is equipped with a slinger fan. (See drawing.)
The fan’s outer ring picks up the condensed water from the base pan if the water level gets high enough. The water is then picked up by the fan and expelled through the condenser, making the air conditioner more efficient.

MAINTENANCE

WARNING
Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops.

Air Filter
Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator.

Cleaning the Air Filter

Remove the air filter from the front grille by pulling the filter forward and then up slightly.
Wash the filter using lukewarm water below 40 °C (104 °F).
Gently shake the excess water from the filter.
Dry the filter in the shade.
Insert the filter into the Front grille.

Cleaning the Air Conditioner

Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution.
Wash the cabinet with mild soap or detergent and lukewarm water, then polish using liquid appliance wax.
NOTE
- To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air.
- For repair and maintenance, contact a LG Electronics Customer Information Center. See the warranty card for details. Have your model number and serial number available.
