FILTER CARTRIDGE AND WATER HARDNESS
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 mist coming out from the unit for a few seconds. If a white deposit has been left
on the mirror (a sign of lime scale), the cartridge needs to be replaced.
CLEAN CUBE
Before attaching the water tank, insert the "Clean Cube" in the base in the position indicated.
The Clean 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 Clean Cube, you should replace the water on a daily basis.
USEFUL INFORMATION:
Information on how an ultrasonic humidifier works:
How does the ultrasonic humidifier 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.
White dust:
The ultrasonic humidifier 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 possible, the water is fed through the filter 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
filter cartridge needs replacing (see the chapter on "Filter Cartridge and Water Hardness").
