Miele G 7893 Operating Instructions Manual page 7

The washer-disinfector must be
disconnected from the mains electricity
supply before any maintenance or
repair work is carried out. Do not
reconnect it until the maintenance or
repair work has been successfully
completed.
The following points should be
observed to assist in maintaining
quality standards when processing
laboratory equipment and medical
devices, in order to protect patients
and to avoid damage to the loads
being cleaned.
If the washer-disinfector is being
used for disinfection in accordance with
official regulations on the control of
epidemics, the steam condenser and
its connections to and from the wash
cabinet must be cleaned and
disinfected whenever any repairs are
carried out or parts replaced.
If it is necessary to interrupt a
programme in exceptional
circumstances, this may only be done
by authorised personnel.
The standard of cleaning and
disinfection in the disinfection
programmes must be routinely
confirmed by the user. The process
must be thermo-electrically validated
on a regular basis, and checked
against documented control results.
Chemical disinfecting procedures
should also be monitored using
chemical or bio indicators.
Warning and Safety instructions
For thermal disinfection, use
temperatures and temperature holding
times to achieve the required infection
prophylaxis in accordance with current
health and safety regulations.
Medical products are processed by
thermal disinfection. Items such as
theatre shoes which are not heat
resistant can be processed using a
chemical disinfection agent. The range
of effective disinfection is based on
claims made by the producer of the
disinfecting agent. Their instructions on
handling, use and effectiveness must
be observed. Chemo-thermal
disinfection is not suitable for
reprocessing medical devices.
Chemical agents could, under
certain conditions, cause damage to
the washer-disinfector. Follow the
recommendations of the chemical
agent manufacturer. In the event of any
damage or material deterioration
please contact Miele.
Pre-treatments with cleaning or
disinfecting agents can create foam, as
can certain types of soiling and
chemical agents. Foam can have an
adverse effect on the disinfection and
cleaning result.
Foam must not be able to escape
from the wash cabinet. It would hinder
the correct functioning of the machine.
Check the process used regularly to
monitor foaming levels.
