In the machine water is heated up. As a result, calcification
occurs during normal use and is indicated automatically.
Before using the machine for the first time the hardness of
the water used must be adjusted. Use the supplied test sticks
for this.
1° German hardness is equivalent to 1.79° French hardness.
The machine has 5 hardness degrees which can be used and are
