3. Setting up your HYDRIM

3.3 Water quality

The quality of the water being used in the HYDRIM to clean the instruments is very critical
to achieving satisfactory cleaning results and to protecting the instruments and the internal
parts of the unit from deterioration.
Drinking water typically contains many dissolved solids. The amount of dissolved solids
greatly depends on the local natural geological conditions and they can cause stains, spots
and corrosion on instruments and on the internal parts of the HYDRIM. Among others, Iron,
Manganese, Chloride, and Calcium Carbonate (CaCO ) are the dominant dissolved solids
3
that affect the cleaning results when using a washer.
Iron and Manganese can cause orange and brown or black stains on the instruments and
on the internal parts of the HYDRIM. Chloride is usually responsible for causing stains,
spotting, pitting and scaling. If the instruments or the inner parts of the HYDRIM C61w,
such as the chamber, show any of these spots or stains, a water test may be required to
determine the cause. The installation of a water treatment system may be required to
reduce the amount of dissolved solids in the water and to improve the cleaning
performance of the HYDRIM.
Calcium Carbonate is the principle cause of water hardness and leaves white spots or
scales. The HYDRIM is equipped with a built-in water softening system that must be
adjusted according to the local water hardness. Please see section 3.4 of this manual for
recommended regeneration settings.
Before using the HYDRIM, SciCan recommends testing the water and recording the results
for water hardness, pH value, and water conductivity for future references in the pre-
installation and installation documents.
IMPORTANT: The HYDRIM's water softening system reduces the water hardness by
taking out Calcium Carbonate. If your water testing results show that your water hardness
is outside the unit's range of adjustment, or if other dissolved solids in the water cause
stains or deposits on the instruments or chamber, an external water treatment system may
be required.
