Miele PG 8504 Operating Instructions Manual page 15


Mobile units, baskets, modules, inserts and the load must be
allowed to cool down before they are unloaded. Any water remaining
in containers could still be very hot. Empty them into the wash
cabinet before taking them out.

Never clean the machine or near vicinity with a water hose or a
pressure washer.

The machine must be disconnected from the mains electricity
supply before any maintenance or repair work is carried out.
Quality assurance
The following points should be observed to assist in maintaining
quality standards when processing laboratory glassware and
utensils to avoid damage to the loads being cleaned.

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 must be routinely
confirmed by the user. The process should be validated on a regular
basis, and checked against documented control results.

Make sure items being washed are suitable for machine
reprocessing and are in good condition. Plastic items must be
thermally stable. Nickel plated items and aluminium items can be
machine processed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.

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.

Abrasive substances must not be placed in the machine as they
could cause damage to the mechanical components of the water
supply. Any residues of abrasive substances on items to be washed
must be removed without trace before reprocessing in the machine.

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 cleaning result.

Processes must be set up such that foam cannot escape from the
wash cabinet. It would hinder the correct functioning of the machine.

The process used must be monitored on a regular basis by the
supervisor to check foaming levels.

To avoid the risk of damage to the machine and any accessories
used with it caused by chemical agents, soiling and any reaction
between the two please read the notes in "Chemical processes and
technology".
