NOTE:

During the JET COOL function at any moment, the A/C starts to blow the cool air at extremely high speed for 30 minutes setting the room temp. automatically to 18^ . It is especially used to cool the room temp. in the shortest time in a hot summer.
In heat pump mode or neuro fuzzy mode, however, the JET COOL function is not available.

☐ In order to return to the normal cooling mode from the JET COOL mode, you just press either the operation mode selection button, airflow volume selection or temp. setting button or the JET COOL button again.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center.

Case	Explanation	See page
The air conditioner does not operate.	·Have you made a mistake in timer operation?	13
	·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 restarted.	·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.	16
	·Has the temperature been set incorrectly?	7, 10
	·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.	-
Remote control display is faint, or no display at all.	·Are the batteries depleted?·Are the batteries inserted in the opposite (+) and (-) directions?	4
Crack sound is heard.	·This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.	-
