SAFETY INFORMATION

To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines.

General Safety

• Only use the humidifier as described in this manual.
• Place the humidifier and cord so that the humidifier will not be knocked over.
• When not in use, turn the humidifier off and disconnect from power source by removing the plug from the outlet.
• Do not overfill the water tank, as this may cause electric shock.
• Do not use the humidifier in wet environments.
• Keep the humidifier out of reach from children.
• Do not open the base or remove the water level sensor for self-servicing.
• Always unplug the humidifier from the power outlet before cleaning the humidifier or detaching the water tank from the humidifier base.
• Always make sure the humidifier is placed on a flat, level surface before operation.
• Only fill the water tank with purified or distilled water. Never fill the water tank with any other liquids unless directed by the manual.
• Do not place the humidifier near sources of heat, such as stovetops, ovens, or radiators.
• Do not place the humidifier directly on floors, carpets, or rugs. Only place the humidifier on water-resistant surfaces.
• Do not use attachments that are not recommended by Levoit for the humidifier.
• Do not cover the nozzles while the humidifier is on. Doing so may damage the humidifier.
• Remove the water tank from the base before moving the humidifier.
• Do not immerse the humidifier base, power cord, or plug in water.
• Do not place foreign objects into the humidifier's base or water tank.

Risk of Leaks and Electric Shock

• Do not add essential oils, supplemental water treatment liquids, or third-party water filters into the water tank or base. This will damage the humidifier and cause leaks. Only add essential oils to the aroma pad.
• If the humidifier is damaged or is not functioning properly, stop using it and contact Customer Support immediately.

Power and Cord

• Do not handle the power cord or plug with wet hands. Keep the plug and power cord away from liquids.
• This humidifier has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature.

Not for commercial use. Household use only.

TROUBLESHOOTING

Problem	Possible Solution
No mist comes out of the nozzles.	Plug in the humidifier and turn it on.
	Add at least 2 US cups / 475 mL of purified or distilled water to the water tank.
	Clean the humidifier (see Keeping Things Clean).

Only a small amount of mist comes out of the nozzles.	Clean the humidifier, especially the nozzles, air vent, and transducer (see Keeping Things Clean).
Humidifier uses water too quickly.	The humidifier uses up water based on the environmental temperature and humidity. If your environment is cold and/or dry, the humidifier will run out of water faster.
Humidifier produces an unusual smell.	If the humidifier is new, remove the water cap, and place the water tank in a cool, dry place for 12 hours.
	If essential oils were diffused on the aroma pad, rinse the pad and allow it to dry.
	Clean the humidifier (see Keeping Things Clean).
Humidifier makes a loud or unusual noise.	Make sure the water tank is properly in place (see Getting Started).
	Place humidifier on a flat, level surface.
	Make sure there is at least 2 US cups / 475 mL of purified or distilled water in the water tank.
	When using the warm mist function, the heating element will make a gurgling noise when the water level is low. Add more water to the water tank.
	The humidifier may be malfunctioning. Stop using the humidifier and contact Customer Support.

The humidity level isn't changing in my room.	Use a higher mist level setting.
	Depending on your environment, the humidifier may take longer to humidify your air.
	The humidifier has a maximum effective range of 430–753 ft² / 40–70 m². If the room is larger, the humidifier will not be as effective.
The humidifier does not respond to the remote.	Move remote control to within 16 ft / 4.8 m of the humidifier.
	Remove the plastic tab from the battery compartment.
	Change the battery (see Replacing the Remote Control Battery).
Incorrect humidity percentage is displayed.	The room may be larger than the humidifier's effective range. Move to a room smaller than 430–753 ft² / 40–70 m².
	Moisture may have built up inside of the humidity sensor. Turn off the humidifier and allow the sensor to air dry. Make sure the nozzles are facing away from the sensor.
	If the humidifier is placed within 12 in / 30 cm of a wall or in a corner, the built-in humidity sensor cannot provide a proper reading for the relative humidity in the room.
	The humidity sensor will give an improper reading if it is exposed to dust. Avoid using the humidifier in dusty rooms.
