- For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal block.

- Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible.

- Over-tightening the terminal screws may break them.

MAINTENANCE

Clean the product regularly to maintain optimal performance and to prevent possible breakdown.

LG UL12FH - MAINTENANCE - 1

CAUTION

  • Turn off the power and unplug the power cord before you perform any maintenance; otherwise it may cause electric shock.
  • Never use water that is hotter than 40 °C when you clean the filters. It may cause deformation or discoloration.
  • Never use volatile substances when you clean the filters. They may damage the surface of the product.

Operation Tips!

  • Do not overcool the room. This is not good for the 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 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. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean 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.

When the air conditioner is not going....

When air conditioner is not going to be used for a long time.

1 Operate the air conditioner at the following settings for 2 to 3 hours.
- Type of operation: Fan operation mode.(Refer to page "Fan Mode")
• This will dry out the internal mechanisms.

2 Turn off the breaker.

LG UL12FH - When the air conditioner is not going.... - 1

CAUTION

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

3 Remove the batteries from the Remote Controller.

Helpful information

The air filters and your electric bill.

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

When the air conditioner is to be used again.

1 Clean the air filter and install it in the indoor unit. (Refer to page "Maintenance and Service")
2 Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
3 Check that the ground wire is connected correctly. It may be connect to the indoor unit side.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the malfunction persist, please contact your dealer.

CaseExplanation
The air conditioner does not operate.Have you made a mistake in timer operation?Has the fuse blown or has the circuit breaker been tripped?
The room has a peculiar odor.Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.
It seems that condensation is leaking from the air conditioner.Condensation occurs when the airflow from the air conditioner cools the warm room air.
Air conditioner does not operate for about 3 minutes when restart.This is the protector of the mechanism.Wait about three minutes and operation will begin.
Does not cool or heat effectively.Is the air filter dirty? See air filter cleaning instructions.The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down.Has the setting temperature been set incorrectly?Are the indoor unit's air inlet or outlet vents obstructed?
The air conditioner operation is noisy.For a noise that sounds like water flowing.- This is the sound of freon flowing inside the air conditioner unit.For a noise that sounds like the compressed air releasing into atmosphere.- This is the sound of the dehumidifying water being processed inside the air conditioning unit.
Crack sound is heard.This sound is generated by the expansion/contraction of the inlet grille, etc. due to changes of temperature.
Remote control display is faint, or no display at all.Has the circuit breaker been tripped?Are the batteries inserted in the opposite (+) and (-) directions?
The error code is occurred after lightning struckThis product has been applied to the over current protection circuit. Error can occur, but it is normal behavior. After few minutes, It will operate normally.
