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).
    Install the Unit

Warning Icon CAUTION The external grille must be exposed outside for air discharge.

Drain Pipe

In humid weather, excess water may cause the base pan to overflow. To drain the water, remove the drain cap and secure the drain pipe to the rear hole of the base pan.

Press the drain pipe into the hole by pushing down and away from the fins to avoid injury.
Drain Pipe

Warning Icon CAUTION

Be careful when inserting the drain pipe. Push away from the sharp fin area to avoid slipping injuring yourself.

Space for Outside Air Flow

Unit Installation

Warning Icon CAUTION

The power cord must be connected to an independent circuit. The green wire must be grounded.

Stuff the foam between the top of the unit and the wall to prevent air and insects from getting into the room.

OPERATION

Control Panel
Control Panel

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

  1. Power
    Turns the air conditioner on or off.
  2. Fan Speed
    Use to set the fan speed to LOW or HI.
  3. Mode/Temp Control Knob
    Use to set the air conditioner to the Fan Only (VENT.) or the Cool (FRIO) mode.
    Fan Only (VENT.) – Use Fan Only (VENT.) at HI or LOW Fan Speed (Velocidad) to provide air circlulation and filtering without cooling.
    Cool (FRIO) – Use Cool (FRIO) with HI or LOW Fan Speed (Velocidad) for cooling. Turn the knob toward the Cooler (Max.) area for the indoor air to become cooler. Turn the knob toward the Cool (FRIO) area for the indoor air to to become warmer. The Mode/Temp control is used to maintain the room temperature. When set in the Cool (FRIO) mode, the compressor will cycle on and off to keep the room at the same level of comfort.

NOTE

If you move the Mode/Temp control knob from the Cool (FRIO) setting to the Fan Only (VENT.) setting, wait at least 3 minutes before swiching back to a Cool (FRIO) setting.

Air Direction

Air Direction

Adjusting the air direction using the horizontal air deflector control.

Using the control tabs, the air flow can be directed to the left, right, straight ahead, or any combination of these directions.
Air Direction

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.
Slinger Fan

MAINTENANCE

Warning Icon 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

  1. Remove the air filter from the front grille by pulling the filter forward and then up slightly.
    Cleaning the Air Filter
  2. Wash the filter using lukewarm water below 40 °C (104 °F).
    Cleaning the Air Filter
  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.
    Cleaning the Air Conditioner

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 or call 55-5321-1919. Have your model number and serial number available.

TROUBLESHOOTING

Before Calling for Service

The appliance is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the appliance does not function properly or does not function at all, check the following before you call for service.

Normal Sounds You May Hear
Normal Sounds

  1. High Pitched Chatter
    Today’s high efficiency compressors may have a high pitched chatter during the cooling cycle.
  2. Sound of Rushing Air
    At the front of the unit, you may hear the sound of rushing air being moved by the fan.
  3. Gurgle/Hiss
    Gurgling or hissing noise may be heard due to refrigerant passing through evaporator during normal operation.
  4. Vibration
    Unit may vibrate and make noise because of poor wall or window construction or incorrect installation.
  5. Pinging or Swishing
    Droplets of water hitting condenser during normal operation may cause pinging or swishing sounds.

Problem

Possible Causes & Corrective Action

Air conditioner does not start. The air conditioner is unplugged.
Make sure the air conditioner plug is pushed completely into the outlet.
The fuse is blown/circuit breaker is tripped.
Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
Power failure.
If power failure occurs, turn the mode control to off. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
Air conditioner does not cool as it should. Airflow is restricted.
Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
The temp control may not be set correctly.
Set the desired temperature to a level lower than the current temperature.
The air filter is dirty.
Clean the filter at least every 2 weeks. See the ‘MAINTENANCE (Cleaning the Air Filter)’ section.
The room may have been hot.
When the air conditioner is first turned on, you need to allow time for the room to cool down.
Cold air is escaping.
Check for open fumace floor registers and cold air returns.
Cooling coils have iced up.
See ‘Air conditioner freezing up’ below.
Air conditioner freezing up. The cooling coils are iced over.
Ice may block the air flow and obstruct the air conditioner from properly cooling the room. Set the Fan Speed High at Fan or Cool mode.
Water drips outside. Hot, humid weather.
This is normal.
Water drips Indoors. The air conditioner is not tilted to the outside.
For proper water disposal, make sure the air conditioner slants slightly from the cabinet front to the rear.
Water collects in base pan. Moisture removed from air and drains into base pan.
  • This is normal for a short period in areas with little humidity; normal for a longer period in very humid areas.
Air conditioner turns on and off rapidly. Dirty air filter – air restricted.
  • Clean air filter.
  Outside temperature extremely hot.
  • Refer to installation instructions or check with installer.
Noise when unit is cooling. Air movement sound.
  • This is normal. If too loud, set to lower FAN Speed.
  Window vibration – poor installation.
  • Refer to installation instructions or check with installer.
Room too cold. Set temperature too low.
  • Increase set temperature.
