Miele PG 8063 Operating Instructions Manual page 15


The machine must be disconnected from the mains electricity sup-
ply before any maintenance or repair work is carried out.
Quality assurance
The following points should be observed to assist in maintaining
quality standards when reprocessing air regulators and breathing
masks and to avoid damage to the load items being cleaned.

If it is necessary to interrupt a programme in exceptional circum-
stances, this may only be done by authorised personnel.

Make sure items being washed are suitable for machine repro-
cessing and are in good condition. Plastic items must be thermally
stable. Nickel plated items and aluminium items can be machine pro-
cessed 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 and disinfection 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 su-
pervisor 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".

When using process chemicals, always consult the instructions is-
sued by individual manufacturers. Process chemicals must only be
used for the purpose they are designed for by the manufacturer to
avoid any material damage or the occurrence of very strong chemical
reactions (e.g. oxyhydrogen explosion).

Always follow the relevant manufacturer's instructions on storage
and disposal of chemical agents.
