How to Install the Unit

1. Measure the space for installation to assure a good fit. The air conditioner must be installed firmly into place to prevent vibration and noise.
2. Avoid exposure to direct sunlight.
3. Remove all obstacles from the rear of the unit. There must be at least 50 cm (20 in.) of cleared space around the rear of the unit. Obstacles restricting the airflow may reduce the cooling efficiency of the unit.
4. The unit should be installed with a slight tilt towards the outside to allow condensed water to drain. (About 10~15 mm or 1/4 bubble with Level)
   

CAUTION

• The external grille must be exposed outside for air discharge.
• As the minimum installation height is 75cm. Please be aware the requirement of installation height

Drainage (Optional)

The base-pan may overflow due to high humidity. To drain the excess water, remove the drain cap from the base pan of the unit and secure the Drain Pan.

OPERATION

Control Panel and Remote Control

NOTE

• The feature may be changed according to the type of model.

1. Power
   Press to turn the air conditioner ON or OFF.

2. Sleep Mode
   This mode keeps operating noise to a minimum and turns the air conditioner off after a set time. The timer can be set from 1 to 12 hours
   ● In the Cool, Energy Saver, Dry Mode setting temperature increases by 1 °C after 30 minutes and additional 1 °C after another 30 minutes for a more comfortable sleep.
   ● The setting temperature increases up to 2 °C from the preset temperature.

3. Delay ON/OFF Timer
   Delay ON – When the air conditioner is off, set it to automatically turn on from 1 to 24 hours later, at its previous mode and fan settings.
   Delay OFF – When the air conditioner is on, set it to automatically turn off from 1 to 24 hours later.
   NOTE
   ● Each press of the Timer button advances the timer by 1 hour. After the last press the display returns to the temperature setting.

4. Operation Mode Press the Mode button to cycle between 4 types of air conditioner operation: Energy Saver / Cool / Fan / Dry. 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.

2. Wash the filter using lukewarm water below 40 °C (104 °F).

3. Gently shake the excess water from the filter.

4. Dry the filter in the shade.

5. 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 Service Hotline. Have your model number and serial number available.
