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 international stan-
dard EN ISO 15883-1
(CAN/CSA-Z15883).

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
washer-disinfector and on the
baskets and inserts,
– the wash cabinet and the door seals,
– the mobile units, baskets, and
inserts.
