To avoid the build-up of calcium depos-
its on items being cleaned and disin-
fected in the washer/disinfector, the
water may need to be softened (where
the supply hardness exceeds 107 ppm
CaCO3).
To ensure a steady supply of soft water,
the water softener must always be:
– correctly set
– regenerated with salt as soon as the
REACTIVATION indicator light comes
on.
The water softener should be set to cor-
respond with the water hardness upon
installation of the washer/ disinfector.
Your local water authority can advise
you on the water hardness in your area.
Setting the water softener
The hardness range is divided into 18
units and a zero position. The washer/
disinfector is set at the factory for a
water hardness setting of 8, corre-
sponding to 339 ppm CaCO3. If your
water supply is harder or softer than
this, change the setting as follows:
