Setting the water softener
The water softener removes minerals and salts from the water supply. Minerals and salts
can have a bad effect on the operation of the appliance.
Equivalent scales measure the water hardness:
• German degrees (dH°).
• French degrees (°TH).
• mmol/l (millimol for each litre - international unit for the hardness of water).
• Clarke degrees.
Adjust the water softener to the water hardness in your area. If necessary, contact your
local water authority.
