Process validation

It is the responsibility of the operator to
routinely check that the required
cleaning and disinfection processes
are functioning properly.
In some countries, this is also required
by national legislation, regulations or
recommendations.
Operators are also required to conduct
such checks under the international
standard EN ISO 15883.

Routine checks

Before each day's use, the operator
must conduct a series of routine
checks. A routine checklist is supplied
with the washer-disinfector.
The following items must be checked:
– the filters in the wash cabinet,
– the spray arms in the chamber and
on the baskets and inserts,
– the wash cabinet and the door seals
and
– the mobile units, baskets and inserts.
