water basin.

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 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
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 water basin, transducer, and inner surface of the water tank.
Scales on the surface of transducer will let the humidier work improperly.
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.
