Water Softener; Programming The Water Softener - Miele G 7883 Operating Instructions Manual

In order to achieve good cleaning
results, the lab washer needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on laboratory glassware and
utensils etc. and in the lab washer.

higher than 4 gr/gal (70 ppm CaCO
needs to be softened. This takes place
automatically in the integrated water
softener.
– The water softener requires
reactivation salt.
– The lab washer must be
programmed to correspond to the
water hardness in your area.
– Your local water authority will be able
to advise you on the water hardness
in your area.
