•
Descale the humidifier as appropriate for the hardness of the water, but at least once a week:
First remove the water tank (the upper section) and clean it with a brush. Descale the device
with a standard descaler and then rinse it thoroughly. Reassemble the device completely be-
fore use.
•
Thoroughly rinse out the water tank on a regular basis.
•
Replace filter cartridge (9) every 1-2 months as appropriate for the hardness of the water.

•
The life-span of the cartridge is dependent on the hardness of the water. This can be tested
using the test strip supplied (The test strip is adhered to the reverse side of this instruction
manual).
•
Dip the test strip into the water for one second.
•
After approx. one minute, the result can be seen on the measuring strip. Some of the green
areas will change their colour to pink. The number of pink areas corresponds to the hardness
of the water.
•
Example: If there are three pink areas, the water has a hardness of "3".

A simple test can be carried out to determine whether the cartridge is functioning correctly: hold a
small mirror in the steam for a few seconds. If a white deposit has been left on the mirror (a sign of
lime scale), the cartridge needs replacing.
IonIc SILVER cuBE™ (optIonAL)
Before attaching the water tank, insert the "Ionic Silver Cube™" in the base in the position indi-
cated.
The Ionic Silver Cube™ with its patented technology prevents the growth of bacteria and germs. It
can be used for a maximum of one season, and must be replaced at the start of the next heating
season (i.e. when the weather becomes cold).
Despite using the Ionic Silver Cube™, you should replace the water on a daily basis.

Information on how an ultrasonic vaporiser works
How does the ultrasonic vaporiser work? An ultrasonic membrane in the interior of the device
causes the water to oscillate, causing very fine droplets of water to be "catapulted off" from the
water surface. These droplets mix with the air in the spray chamber and are then blown into the
room through a ventilator as a visible spray. This fine spray evaporates in the warm air in the room,
moistening the air that people breathe.
