White dust:
The ultrasonic humidifier’s method of action causes all substances contained in the water to be
sprayed, including calcium carbonate (a cause of limescale) and minerals. In order to prevent this
as far as possible, the water is fed through the anticalc cartridge before being sprayed. The cartridge
retains a large percentage of the substances contained in the water. Tap water varies greatly from
region to region in terms of its calcium and mineral content. Some minerals cannot be sufficiently
filtered by the descaling resin used. In this case, a white, dust-like deposit is left in the room, which is
first visible on electro-statically charged surfaces (such as TV sets). This deposit also occurs when the
anticalc cartridge needs replacing (see the chapter on “Anticalc Cartridge and Water Hardness”).
Tips for water:
Clean water must always be used to ensure that the air remains hygienic to breathe. The device, and
the water tank in particular, must always be hygienically clean.
Recommendation: always use the Clean Cube, as this reduces the formation of germs in the water.
Hygrostat:
The standard-tolerance of an integrated hygrostat is +/- 10%. That means the effective relative
humidity level can deviate accordingly.
TROUBLE-SHOOTING
Red control display does not go out after tank has been filled with water:
The device switches off automatically if there is insufficient water. The colour of the light diode (on
the front) then changes from blue to red. To restart the generation of spray, the device must first
be switched off and then switched back on again (this resets the device). This is a protective function
for the ultrasonic humidifier .
Device does not switch on although the water tank has been attached and the on-button has been
pressed:
This is not a malfunction. It can take several minutes before sufficient water for operation has run
from the water tank through the cartridge and into the base. Wait and then press the on-button again.
The water tank is leaking:
Unscrew the lid, screw the cartridge in firmly and screw the lid back on to the tank.
Low performance, no steam output, device not functional:
Perform maintenance as described in the chapter on “Cleaning Procedure”.
