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