Water hardness
Contact your local water supplier to find
out your local water hardness range if
necessary.
The degree of hardness can be set
between 1 °dH and 70 °dH.
If you are using bottled drinking water,
such as mineral water, be sure not to
use carbonated water. Select settings
according to the calcium content. The
calcium content is given on the label of
the bottle in mg/l Ca
2+
or ppm
(mg Ca
2+
/l).
