MAINTENANCE

WARNING

- Turn off the power and unplug the power cord before you perform any maintenance; otherwise it may cause electric shock.

If the air conditioner will not be used for an extended period of time, dry the air conditioner to maintain it in best condition. Clean the product regularly to maintain optimal performance and to prevent possible breakdown.

• Dry the air conditioner in Fan mode for 3 to 4 hours and disconnect the power. There may be internal damage if moisture is left in its components.
• Before using the air conditioner again, dry the inner components of the air conditioner in Fan mode for 3 to 4 hours. This will help to remove the odor generated from moisture.

TROUBLESHOOTING

Self-diagnosis Function

This product has a built-in self-diagnosis function. If an error occurs, the lamp of the indoor unit will blink in 2 second intervals. If this occurs, contact your local dealer or service center.

Before Calling for Service

Please check the following before you contact the service center. If the problem persists, contact your local service center.

Problem Possible Causes Corrective Action
The air conditioner does not work normally.	Burning smell and strange sounds are coming from the unit.	Turn off the air conditioner, unplug the power cable or disconnect the power supply, and contact the service center.
	Water leaks from the indoor unit even when the humidity level is low.
	The power cable is damaged or it is generating excessive heat.
	A switch, a circuit breaker (safety, ground), or a fuse is not operated properly.
	The unit generates an error code from its self-diagnosis.
The air conditioner does not work.	The air conditioner is unplugged.	Check whether the power cord is plugged into the outlet or the power isolators are switched on.
	A fuse exploded, or the power supply is blocked.	Replace the fuse or check if the circuit breaker has tripped.
	A power failure has occurred.	Turn off the air conditioner when a power failure occurs.When the power is restored, wait 3 minutes and then turn on the air conditioner.
	The voltage is too high or too low.	Check if the circuit breaker has tripped.
	The air conditioner was turned off automatically at a preset time.	Turn the air conditioner on.
	The battery setting in the remote controller is incorrect.	Make sure that the batteries are inserted correctly in your remote controller.If the batteries are placed correctly, but the air conditioner still does not operate, replace the batteries and try again.
The air conditioner does not emit cool air.	Air is not circulating properly.	Make sure that there are no curtains, blinds, or pieces of furniture blocking the front of the air conditioner.
	The air filter is dirty.	Clean the air filter once every 2 weeks.See “Cleaning Air Filter” for more information.
	The room temperature is too high.	In summer, cooling the indoor air fully may take some time. In this case, select the Jet Mode to cool the indoor air quickly.
	Cold air is escaping from the room.	Make sure that no cold air is escaping through the ventilation points in the room.
	The desired temperature is higher than the set temperature.	Set the desired temperature to a level lower than the current temperature.
	There is a heating source nearby.	Avoid using heat generators like electric ovens or gas burners while the air conditioner is in operation.
	Fan Mode is selected.	During Fan Mode, air blows from the air conditioner without cooling or heating the indoor air.Switch the operation mode to cooling operation.
	Outside temperature is too high.	The cooling effect may not be sufficient.
The fan speed cannot be adjusted.	The Jet Mode, or Auto Operation Mode is selected.	In some operation modes, you cannot adjust the fan speed. Select an operation mode in which you can adjust the fan speed.
The temperature cannot be adjusted.	The Fan Mode or Jet Mode is selected.	In some operation modes, you cannot adjust the temperature. Select an operation mode in which you can adjust the temperature.
The air conditioner stops during operation.	The air conditioner is suddenly turned off.	The Timer Function may have timed out, which turns the unit off. Check the timer settings.
	A power failure has occurred during operation.	Wait for the power to come back. If you have the Auto Restart function enabled, your unit will resume its last operation several minutes after power is restored.
The indoor unit is still operating even when power has been turned off.	The Auto Clean function is being operated.	Allow the Auto Clean function to continue since it removes any remaining moisture inside the indoor unit. If you do not want this feature, you can turn the unit off.
Problem Possible Causes		Corrective Action
The air outlet on the indoor unit is discharging mist.	The cooled air from the air conditioner makes mist.	·When the room temperature decreases, this phenomenon will disappear
Water leaks from the outdoor unit.	In the heating operations, condensed water drops from the heat exchanger.	·This symptom requires installing a drain hose under the base pan. Contact the installer.
There is noise or vibration.	A clicking sound can be heard when the unit starts or stops due to movement of the reversing valve. Creaking sound: The plastic parts of the indoor unit creak when they shrink or expand due to sudden temperature changes. Flowing or Blowing sound: This is the flow of refrigerant through the air conditioner.	·These are normal symptoms. The noise will stop.
The indoor unit gives off an odor.	Odors (such as cigarette smoke) may be absorbed into the indoor unit and discharged with airflow.	·If the smell does not disappear, you need to wash the filter. If this does not work, contact the service center to clean your heat exchanger.
The air conditioner does not emit warm air.	When Heating Mode starts, the vane is almost closed, and no air comes out, even though the outdoor unit is operating.	·This symptom is normal. Please wait until the unit has generated enough warm air to blow through the indoor unit.
	The outdoor unit is in Defrosting Mode.	·In Heating Mode, ice/frost is built up on the coils when the outside temperature falls. This function removes a layer of frost on the coil, and it should finish in approximately 15 minutes.
	Outside temperature is too low.	·The heating effect may not be sufficient.
The air conditioner changes generated airflow during operation.	When the air conditioner reaches the desired temperature, the airflow rate reduces in order to avoid generating cool airflow during heating, or to minimize energy consumption and indoor humidity change during cooling.	·This symptom is normal.

NOTE

- Some functions may not be supported, depending on the model.
