5. TROUBLESHOOTING

Below is a list of some of the possible malfunctions.

If the problem cannot be resolved as described, contact Customer Service.

PROBLEM	CAUSE	SOLUTION
No discharge of air	Cord is not plugged in	Make sure power cord is plugged in and the swi-tch is ON
	Power is not ON	Turn the unit ON by pressing the ➊ button (B1 on the control panel or D1 on the remote control)
The appliance switches off	The auto shutoff timer was set	Turn the appliance ON and check that the auto shutoff symbol is off
Excessive humidity in the room	In Cooler/Humidifying function, the ap- pliance produces moisture as a result of evaporative cooling. This is normal	The appliance cools best in dry climates. If the ambient humidity level is high (60% or above) re-frain from using the cooler/humidifying function
		Make sure the window/doors are open and there is adequate cross ventilation in the room so that the air can circulate better. Utilize the “fan” function
Odors and colored water	When the appliance is new	At first use, the appliance will have an odor, which will dissipate within a few hours of initial use. The color in the water will also dissipate after a few uses.
	Algae or mold due to moisture. In very damp conditions, algae may form due to moisture	Check the Honeycomb Cooling Pad (A12), water tank (A7) and other cooler parts. If you see mold spots or algae issue, use a damp cloth to wipe away the algae until all spots have disappeared. Make sure all parts are clean and dry before storage. Contact Customer Service if problem persists. If the Honeycomb Cooling Pad (A11) has algae or mold, change it with a new one
Remote control does not work	Remote control battery is incorrectly inserted in the battery compartment	Check the battery is correctly inserted following the polarity guide inside the battery compartment.
	Remote control battery is exhausted	Replace with a new battery
	Damaged remote control	If replacing new battery in the correct position does not work, contact Customer Service
The unit does not respond	Damaged control panel on unit	Try to activate the unit with the remote control If the unit responds, then the control panel on the unit may be experiencing problems: contact Customer Service
		If neither the remote control or the control panel is working, contact Customer Service
If “Cooler/Humidifier” indicator flashes and unit beeps	Because of no water in the tank	Fill tank above MIN mark with water
