Warning and Safety Instructions
14

Always allow wash carts, baskets, modules, inserts, and loads to
cool down before unloading. Any water remaining in concave items
could still be very hot. Empty them into the wash cabinet before
taking them out.

Never clean the machine or surrounding area 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 reprocessing laboratory glassware and
accessories and to avoid damage to the loads being cleaned.

If it is necessary to interrupt a program in exceptional
circumstances, this may only be done by authorised personnel.

The standard of reprocessing 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
processing and are in good condition. Plastic items must be thermally
stable. Nickel plated items and anodised aluminum items can be
machine processed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.

Under certain circumstances process chemicals can cause
damage to the machine. Always follow the recommendations of the
process chemical manufacturers.
In case of damage or doubt about compatibility, please consult with
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-treating (e.g. with cleaning agents or disinfectants), some
types of soiling and the interaction of certain process chemicals can
cause foaming. Foam can have an adverse effect on the cleaning
result.

The process must be set so that no foam escapes the wash
compartment. Escaping foam jeopardizes the safe operation of the
machine.

The process must be checked regularly in order to detect any
foaming.
