Miele G 7881 Installation And Operating Instructions Manual page 12

Description of the machine
Do not clean fiberoptics or electrical
equipment and components in the
washer-disinfector.
Rhodium coated mirrors must be
arranged so that their surfaces do not
suffer any mechanical damage. Not all
specula with glass are suitable for
machine treatment.
If you have questions regarding
whether an item is suitable for
processing in the washer-disinfector,
please seek the advice of the item
manufacturer.
Water Quality
Good water quality is essential for
processing items in the
washer-disinfector, otherwise, item
corrosion may result.
Poor water quality consists of, but is not
limited to, high concentrations of
chlorides (over 50 ppm). High chloride
levels will cause even high quality
stainless steel items to rust when
processed in the washer-disinfector.
Other effects that may be noticed are
tarnishing or "blueing" of items due to
dissolved minerals in the water.
