8 6 Checking and setting the water
hardness
For registered products, the inflow water hardness
is taken from the hydromaps water hardness da-
tabase. Check that the database value matches the
water hardness at the installation location and adjust
the value for the inflow water hardness if necessary.
►If necessary, press
ENTER VALUE MANUALLY
►Enter the water hardness at the installation
location.
►Select the desired outlet water hardness (luxury
water with approx. 4 °dH), or enter it manually.
After entering, the display automatically skips
forward.
NOTE
► Do not set the outlet water hardness too
low, as this can lead to increased foaming of
soaps (e.g. in the washing machine).
► When setting the outlet water hardness,
ensure that the maximum permissible sodi-
um concentration of 200 mg/l in accordance
with the German Drinking Water Ordinance
is not exceeded.
