• Do not use the humidifier if the air in the room is already sufficiently humid.

• The ideal relative humidity level for human comfort is in fact between 45% and 65%. Excess humidity shows up in the form of condensation on cold surfaces or cold walls in the room. To measure the room’s humidity correctly, use a hygrometer available in most specialist shops and hypermarkets.

• This product is intended for indoor, nonindustrial, non-commercial, household use only.

• Micro-organisms that may be present in the water or in the environment where the appliance is used or stored, can grow in the water reservoir and be blown in the air causing very serious health risks when the water is not renewed and the tank is not cleaned properly every 3 days.

• Keep the appliance out of reach of children. Steam and boiling water may cause burns.

• Clean the water every three days.

• Be aware that high humidity levels may encourage the growth of biological organisms in the environment.

• Do not permit the area around the humidifier to become damp or wet. If dampness occurs, turn the output of the humidifier down. If the humidifier output volume cannot be turned down, use the humidifier intermittently. Do not allow absorbent materials, such as carpeting, curtains, drapes, or tablecloths, to become damp.

The following is not considered faulty operation:

• 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) is considered normal.

MAINTENANCE

If the water is hard, meaning that the water contains too much calcium and magnesium, it can cause a “white powder” problem and leave heavy scales on the surface of water basin, transducer, and inner surface of the water tank. Scales on the surface of transducer will let the humidifier work improperly.

Use cold boiled water or distilled water.

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 on interior surfaces and wipe all surfaces dry.

Empty and clean the humidifier before storage. Make sure all parts are died completely. Clean the humidifier before next use.

HOW TO CLEAN THE TRANSDUCER

• Clean with clean water of citric acid if there is scale in it.
• Brush off the scale from the surface.
• Rinse the transducer with clean water.

HOW TO CLEAN THE BASIN

• If the scale covers the security switch, drop some citric acid on it and let it sitfor 2-5 minutes on the scale and clean it with a brush.
• Rinse the water tank with clean water.

HOW TO CLEAN THE CERAMIC FILTER
