LG LG Air Conditioner (downloadFile_fileId_)

Operate the air conditioner in Air Circulation mode for 2 to 3 hours to dry out the internal parts, then turn off the circuit breaker. The manual cautions that turning off the circuit breaker is important because dirt may collect and cause a fire if the unit is left unused without doing so. (Page 22)

If strange sounds, smell, or smoke come from the product, turn the breaker off or disconnect the power supply cable immediately. There is a risk of electric shock or fire in such situations. Contact an authorized service center for inspection and repair. (Page 5)

The wireless remote controller can receive signals at a distance of up to approximately 7 meters. You should aim at the signal receiver on the wired remote controller and ensure there are no obstructions between the remote controller and the signal receptor. Avoid placing the remote controller in direct sunlight or near heat sources. (Page 9)

The 'Preheat' indicator appears because the air conditioner uses a hot start control to prevent cold air from being discharged at the beginning of heating operation. The 'Defrost' indicator appears when the outdoor temperature is too low, triggering a defrosting operation to maintain performance. Both are normal operating states for the heat pump model.

'CH' flashing on the remote controller display indicates a problem has occurred with the air conditioner. You should contact your dealer when this self-diagnosis code appears. Do not attempt to repair the unit yourself.

The air filters should be checked and cleaned once every 2 weeks or more often if necessary. To clean, use a vacuum or wash with warm, soapy water using a mild detergent in lukewarm water. After washing, dry well in the shade before re-installing — do not use hot water of 50°C or more as it may deform the filter.

The air conditioner will not operate for about 3 minutes when restarted because of a built-in mechanism protector. Simply wait about three minutes and operation will begin automatically. This is normal behavior and not a malfunction.

Dial the number connected to the air conditioner and wait for it to ring 5 times. You will hear a 'Beep' sound (when the unit is off), then press '0', '0', '7', '8' in order. The air conditioner will start and you will hear 'Beep, Beep' to confirm. Note that if someone picks up the phone before 5 rings, the telephone control function will not work.

Press the Timer button and Minute Set button simultaneously for three seconds to activate the Child Lock function. The display will show 'CL' to indicate child lock mode is active. When any button is pressed in this mode, the remote controller will not respond and 'CL' will be displayed for about three seconds.

During Cooling Operation mode, the temperature can be set within a range of 18°C to 30°C in 1°C increments. You should set the temperature lower than the current room temperature for effective cooling. Fan speed can also be selected in three steps: high, medium, or low.

Before leaving the unit unused for an extended period, operate the air conditioner in Air Circulation mode for 2 to 3 hours to dry out the internal parts. Then turn off the circuit breaker, as dirt may collect and cause a fire if the breaker is left on. When ready to use again, check that the air inlet and outlet of the indoor and outdoor units are not blocked.

Before performing any maintenance, turn off the main power to the system and turn off the circuit breaker. When removing the air filter, do not touch the metal parts of the indoor unit as this may cause injury. Do not clean the air conditioner with water as water may enter the unit, degrade insulation, and cause electric shock.

The 'Preheat' indicator appears because the air conditioner uses a hot start control to prevent cold air from being discharged during heating operation startup. The 'Defrost' indicator appears when the outdoor temperature is too low, causing the unit to switch to a defrosting operation cycle. Both are normal operational states during heating mode.

The PLASMA filter should be checked and cleaned once every month or more often if necessary. To clean, dip the filter in water mixed with mild detergent for 20–30 minutes, then dry in the shade for a full day, ensuring all humidity is completely removed. Do not touch the PLASMA filter within 10 seconds after drawing out the Air Cleaner Bracket, as it may cause electric shock, and be careful not to cut the electric discharge lines while washing.
