Water Softener - Miele PG 8536 Operating Instructions Manual

Water softener

In order to provide good cleaning
results, the washer-disinfector requires
a supply of soft water (water that is low
in calcium/limescale). If hard tap water
is used, it can leave a white mineral
deposit build-up on the labware,
instruments and the machine itself.
Therefore, tap water with a hardness of
4 gr/gal (70 ppm CaCO3) or more must
be softened. The built-in water softener
is designed for this purpose.
– In order to function properly, the
water softener requires a supply of
reactivation salt.
– The washer-disinfector must be
correctly programmed to match the
hardness of the tap water supply.
– Your local water authority will provide
information about the hardness of the
tap water in your area.
The factory default for the water
softener is set to a hardness of
19 gr/gal (340 ppm CaCO3).
If the actual water hardness is
different (even if it is below 4 gr/gal),
the factory default setting will need
to be changed using the electronic
control.
If the water hardness is known to
fluctuate (e.g. 8 - 17 gr/gal), always
program for the highest value (in this
instance 17 gr/gal).

The built-in water softener can be
programmed to settings from 1
gr/gal to 60 gr/gal (1 gr/gal is
equivalent to 1 °dH, 60 gr/gal is
equivalent to 60 °dH).
It is useful to make a note of the water
hardness so that you can provide the
service technician with this information
in the event of any service calls.
