Warning and Safety instructions
14

Never clean the machine or near vicinity with a water hose or a
pressure washer.

The washer-disinfector must be disconnected from the mains elec-
tricity supply before any maintenance or repair work is carried out.
The following points should be observed to assist in main-
taining quality standards when reprocessing laboratory
equipment and medical devices, in order to protect patients,
and to avoid damage to the loads being cleaned.

If the machine is being used for disinfection in accordance with of-
ficial 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 re-
placed.

If it is necessary to interrupt a programme in exceptional circum-
stances, this may only be done by authorised personnel.

The standard of cleaning and disinfection in the disinfection pro-
grammes for medical devices must be routinely confirmed by the
user. The process should be validated on a regular basis, and
checked against documented control results.
Chemical disinfection procedures should also be validated using
chemical or bio indicators.

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 means of thermal disinfection.
Disinfection of heat-sensitive items, e.g. theatre shoes, can be carried
out using the CHEM-DESIN programme with the addition of a chem-
ical disinfecting agent. The range of effective disinfection is based on
claims made by the producer of the disinfecting agent. Their instruc-
tions on handling, use and effectiveness must be observed. The use
of chemical disinfection procedures is the responsibility of the oper-
ator.
Chemical disinfection processes of this type are not suitable for the
reprocessing of medical products.

Chemical agents can in certain circumstances cause damage to
the machine. Always follow the recommendations of the chemical
agent manufacturer.
In case of damage or doubt about compatibility, please contact
Miele.

Do not use any abrasive chemical agents in the washer-disinfector.
These can cause damage to machine components, e.g. the spray
arm bearings. If such agents are used for manual pre-treatment of
containers or instruments, these must be removed without trace prior
to processing in the washer-disinfector.
