Children shall not play with the humidifier. Cleaning and user maintenance shall not be done by children without supervision.
Before using this humidifier ensure that the voltage of your electricity supply is the same as that indicated on the rating plate of the humidifier.
Always place the humidifier on a hard, flat, and level surface. Avoid exposure to direct sunlight and always keep it away from walls and heat sources such as stoves, radiators, etc. Warning: The humidifier may not work correctly if it is not placed on a level surface.
Do not insert or remove the electric plug on the humidifier with wet hands.
If the mains cable is damaged it must be replaced by the manufacturer, its service agent, or a similarly qualified person to avoid a hazard.
To reduce the risk of electric shock, do not remove screws. The humidifier does not contain any user-serviceable parts. Please leave all maintenance work to qualified personnel.
Fill the tank with fresh, distilled, or demineralized water. Do not drop any other liquid into a water tank or water basin. Do not run the humidifier when there is no water in the tank or the water basin.
Do not shake the humidifier as this might cause the water to spill over into the base of the humidifier.
Never touch the water or components while the humidifier is in operation.
If there is an unusual smell when it is being used as described in this manual, switch the humidifier off, unplug it, and have it examined by your dealer.
Do not pour hot water into the tank, i.e. at a temperature over 40°C.
Do not immerse the humidifier or the mains cable or plug in water or other liquids.

The following is not considered faulty operation:

If your water is very hard (containing abnormally high levels of minerals) the humidifier may produce white dust. This is not a malfunction. The solution would be to clean the filter more often or use softer water.
If you stand very close to the humidifier, you will hear the gurgling sound of water. This is normal.
The humidifier operates very quietly but it is not completely silent. Noise levels less than 35dB(A) are considered normal.

MAINTENANCE

In case the water is hard, meaning the water contains too much calcium and magnesium, it can cause a “white powder” problem and leave heavy scales on the surface of the water basin, transducer, and inner surface of the water tank. Scales on the surface of the transducer will let the humidifier work improperly. Empty the tank and refill every third day. Before refilling, clean it with fresh tap water. Remove any scale, deposits, or film that has formed on the sides of the tank or interior surfaces, and wipe all surfaces dry. Empty and clean the humidifier before storage.
