The following is not considered faulty operation:
• If your water is very hard (containing abnormally high levels of minerals) the
humidier may produce white dust. This is not a malfunction. The solution
would be to clean the lter more often or use softer water.
• If you stand very close to the humidier, you will hear the gurgling sound of

17
EN
MOIST C ·HU-430CW
water. This is normal.
• The humidier 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 humidier work improperly.
Use cold boiled water or distilled water.
Empty the tank and rell every third day. Before relling, clean it with fresh tap
water or cleaning agents if required by the manufacture. Remove any scale,
deposits, or lm that has formed on the sides of the tank or on interior surfaces
and wipe all surfaces dry.
Empty and clean the humidier before storage. Make sure all parts are died
completely. Clean the humidier 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
• Clean the water basin with a soft cloth or use citric acid if there is scale in it.
• If the scale covers the security switch, drop some citric acid on it and let it sit
for 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
• Clean and activate the ceramic ball after using 1000L water. Depending on
the water quality. If the ceramic ball is dirty it needs to be cleaned more
frequently.
• It can be dipped into vinegar for 5 minutes, then rinse it with water.
• Put the lter under the sun for 4-6 hours to dry.
