5.3 Water connection
CAUTION: The water in the wash tank is not drinkable.
The quality of the water used must be compatible with the
manufacturing materials of the machine, with the chemicals and
with the process needs in the various stages of the procedure.
To have good washing results, the water must be soft and low in
limestone. With hard water white patinas deposit on the objects
to be treated and on the walls of the wash tank.
Starting from a water hardness of 0.7 mmol/l (4 °dH) it is nec-
essary to soften the water. Water hardness is set by technical
assistance.
The water used should at least have the characteristics of
drinking water according to the relevant European legislation
in force. A high iron content can cause rust on the load and in
the special washing and disinfecting machine. If industrial water
contains a higher amount of chlorides than 100 mg/l, the risk
ofcorrosionsignicantlyincreases.
The special washing and disinfecting machine is standard
