Miele G 7825 Operating Instructions Manual page 15


Do not use any abrasive process chemicals in the washer-
disinfector. These can cause damage to machine components, e.g.
the spray arm bearings. If such chemicals are used for manual pre-
treatment of containers or instruments, these must be removed
without trace prior to reprocessing in the washer-disinfector.

Pre-treating (e.g. with cleaning agents or disinfectants), some
types of soiling and the interaction of certain processing chemicals
can cause foaming. Foam can have an adverse effect on the cleaning
and disinfection results obtained.

The process must be set so that no foam escapes the wash
compartment. Escaping foam jeopardizes the safe operation of the
washer-disinfector.

The process must be checked regularly in order to detect any
foaming.

To prevent material damage to the washer-disinfector and
accessories used from the effects of processing chemicals, soiling
and their interaction, follow the notes in chapter "Chemical Processes
and technology".

Even when a chemical additive (e.g. cleaning chemical) is
recommended on technical application grounds, the machine
manufacturer takes no responsibility for the effect of such chemicals
on the material of the items being cleaned.
Note that formulation changes, storage conditions, etc., that are not
disclosed by the chemical manufacturer may adversely affect the
cleaning results obtained.

When using processing chemicals, always follow the instructions
of the chemicals manufacturer. In order to avoid material damage and
possibly violent chemical reactions (such as explosive hydrogen gas
reactions), use processing chemicals only for the applications
intended by the manufacturer.

For critical applications, where very stringent reprocessing
requirements have to be met, it is strongly recommended that all
process-related factors (processing chemicals, water quality, etc.) are
discussed in advance with Miele.

For applications that demand especially stringent cleaning and
rinsing results, the operator must ensure that quality control occurs
on a regular basis to meet the standards involved.

Wash carts, modules and inserts should only be used as intended
by the manufacturer.
Hollow items must be positioned for full exposure to wash water,
internally and externally.

Empty all containers and hollow utensils before loading them into
the machine.
