IMPORTANT SAFETY INSTRUCTIONS

Steam heating is permissible up to a pressure of 145 psi
(1000 kPa). This corresponds to a water steam temperature of 355°F
(180°C).

Never clean the machine with a water hose or a pressure washer.

The machine must be disconnected from the electrical supply be-
fore 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 and avoid damage to the loads being cleaned.

If it is necessary to interrupt a program, as an exception only, this
may only be done by authorized personnel.

The cleaning standard must be routinely confirmed by the user.
The process should be validated on a regular basis, and checked
against documented control results.

For thermal disinfection, use temperatures and temperature holding
times to achieve the required infection prophylaxis in accordance with
current health and safety regulations.

Make sure items being washed are suitable for machine reprocess-
ing and are in good condition. Plastic items must be thermally stable.
Nickel plated items and 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.

Process chemicals can, in certain circumstances, cause damage to
the machine. Always follow the recommendations of the process
chemical manufacturer.
In case of damage or doubt about compatibility, please contact
Miele.

Cleaning detergents containing chlorine can damage the elas-
tomers 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 contain-
ing chlorine may not be used!

Pre-treatments with cleaning agents can create foam, as can cer-
tain types of soiling and process chemicals. Foam can have an ad-
verse 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.
