at the beginning of every humidifying season. The Silver Cube starts work-
ing as soon as it comes into contact with water, and also works when the
unit is switched off.
Anticalc cartridge (optional accessory)
The anticalc cartridge (7) decreases the limescale in the water and thus
reduces the decalcification intervals. The cartridge has to be replaced every
one to three months, depending on the water hardness (see table).
With a water hardness above 21 °dH, we recommend the use of the anticalc
cartridge.
Important:
Soak the anticalc cartridge in a water bath for 24 hours before
the first use (not in the water tank!). The resin has to absorb water to reach
high performance.
The period of time that the cartridge is effective for depends on the hard-
ness of the water. This can be tested using the testing strips provided (see
page 4).
1. Dip the testing strips into the water for a second.
2. After around one minute, the results can be seen on the testing strips.
Some of the green boxes change colour into pink. The water hardness is
shown by how many boxes turn pink. Example: If three boxes are pink, then
the water hardness is > 14 °dH.

The cartridge is screwed onto the inside of the water tank lid (6). First, screw
the tank lid (6) off of the water tank (5) and then affix the cartridge to the
inside of the tank lid. Dispose of used cartridges in the household waste. Do
not throw away the water tank lid when changing the cartridge!
