IMPORTANT SAFETY INSTRUCTIONS
12

Cleaning detergents containing chlorine can damage the
elastomers of the machine.
If the use of process chemicals containing chlorine is required, a
maximum temperature of 167°F (75°C) in the "Cleaning" program
phases is recommended (see program chart).
In machines equipped with special oil-resistant elastomers (from the
factory) for oil and grease applications, cleaning detergents
containing chlorine may not be used!

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 agents can create foam, as can
certain types of soiling and process chemicals. 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 its accessories
caused by process chemicals, soiling, and any reaction between the
two, please read the notes in "Chemical processes and technology".

Even when a process chemical is recommended on technical
application grounds, it does not imply that the manufacturer of the
machine accepts liability for the effect of the chemical on the items
being cleaned.
Please be aware that changes in formulation, storage conditions etc.
which may not be publicized by the chemical manufacturer, can have
a negative effect on the cleaning result.

When using process chemicals, always consult the instructions
issued 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, such as an oxyhydrogen explosion.

Always follow the manufacturer's instructions on storage and
disposal of process chemicals.

In critical applications where very stringent requirements have to
be met, it is strongly recommended that all the relevant factors for the
process, such as process chemicals, water quality, etc., are
discussed with Miele.

If the cleaning result is subject to particularly stringent
requirements, e.g., in chemical analysis, regular quality control should
be carried out by the operator to ensure that required standards of
cleanliness are being achieved.
