 Use of the machine is only permitted for the applications expressly
approved in the operating instructions. Alterations or conversion of
the machine, or using it for purposes other than those for which it
was intended, are not permitted and could be dangerous.
The cleaning and disinfection processes are only designed for labor-
atory glassware and utensils which are designated as reprocessable
by the manufacturer. The information provided by the manufacturer of
the load items must be observed.
 This washer-disinfector is intended for indoor use only.
 The machine is equipped with a special lamp to cope with particu-
lar conditions (e.g. temperature, moisture, chemical resistance, abra-
sion resistance and vibration). This special lamp must only be used
for the purpose for which it is intended. It is not suitable for room
lighting. Replacement lamps may only be fitted by the Miele Cus-
tomer Service Department.
Risk of injury
Please pay attention to the following notes to avoid injury
 This machine must be commissioned, serviced and repaired by a
Miele authorised and trained service technician only. To ensure com-
pliance with Good Laboratory Practice guidelines, Miele repair and
maintenance contracts are recommended. Unauthorised repairs can
pose considerable risks to the user.
 Do not install the machine in an area where there is any risk of ex-
plosion or of freezing conditions.
 The electrical safety of the machine can only be guaranteed when
it is correctly earthed. It is essential that this standard safety require-
ment is observed and regularly tested. If in any doubt, please have
the electrical installation inspected by a qualified electrician.
 A damaged or leaking machine could be dangerous and comprom-
ise your safety. Disconnect the machine from the mains immediately
and call the Miele Service Department.

Warning and Safety instructions
17
 Label machines which have been taken out of operation and se-
cure them from being switched on again without authorisation. The
machine may only be put back into operation once it has been suc-
cessfully repaired by the Miele Customer Service Department.
 Personnel operating the machine should be trained regularly. Un-
trained personnel must not be allowed access to the machine or its
controls.
 Take care when handling chemical agents. These may contain irrit-
ant, corrosive or toxic ingredients.
Please observe the chemical agent manufacturer's safety instructions
and safety data sheets.
Wear protective gloves and goggles.
 Only use process chemicals which have been approved by their
manufacturer for the relevant application. The manufacturer of the
process chemicals is liable for any negative influences on the material
of the load and the machine.
 The machine is designed for operation with water and recommen-
ded additive chemical agents only. Organic solvents and flammable
liquid agents must not be used in it.
This could cause an explosion, damage rubber or plastic components
in the machine and cause liquids to leak out of it.
 The water in the cabinet must not be used as drinking water.
 Be careful when sorting items with pointed ends. Position them in
the machine so that you will not hurt yourself or create a danger for
others.
 Broken glass can result in serious injury when loading or unload-
ing. Damaged glass items must not be reprocessed in the machine.
 When using this machine in the higher temperature ranges, be es-
pecially careful not to scald or burn yourself or come into contact with
irritant substances when opening the door. Where disinfecting agents
are used there is a danger of inhaling toxic fumes.
 Where there is a risk of toxic or chemical substances occurring in
or leaking into the suds solution (e.g. aldehyde in the disinfecting
agent), it is essential to regularly check door seals and make sure that
the steam condenser is functioning correctly. Opening the machine
door during a programme interruption carries particular risks in such
circumstances.
 Should personnel accidentally come into contact with toxic va-
pours or chemical agents, follow the emergency instructions given in
the manufacturer's safety data sheets.
 After using the hot air drying unit, open the door to allow the
everything in the cabinet from the load itself to the mobile units, mod-
ules and inserts to cool down.

Warning and Safety instructions
18
 Mobile units, modules, inserts and the load must be allowed to
cool down before they are unloaded. Any water remaining in contain-
ers could still be very hot. Empty them into the wash cabinet before
taking them out.
 Steam heating is permissible up to a pressure of 1000kPa. This
corresponds to a water steam temperature of 180°C.
 Never clean the machine or near vicinity with a water hose or a
pressure washer.
 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 processing laboratory glassware and
utensils to avoid damage to the loads being cleaned.
 If it is necessary to interrupt a programme in exceptional circum-
stances, this may only be done by authorised personnel.
 The standard of cleaning and disinfection must be routinely con-
firmed 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 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.
 Cleaning agents containing chlorine can damage the elastomers of
the machine.
If the use of cleaning agents containing chlorine is required, a max-
imum temperature of 75°C in the “Main wash” programme phases is
recommended (see programme chart).
Cleaning agents containing chlorine must not be used in machines
supplied (ex works) with special oil-resistant elastomers for oil and
grease applications.

Warning and Safety instructions
19
 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”.
 Even when a process chemical, e.g. cleaning agent, is recommen-
ded, the machine manufacturer takes no responsibility for the effect
of such process chemicals on the load.
Please note that changes in product formulation, storage conditions,
etc. which are not announced by manufacturers of process chemicals
may impair the quality of cleaning results.
 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.
 Particles≥200μm are removed by the filters in the wash chamber.
Smaller particles may find their way into the circulation system.
 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 chemical agents, water quality etc. are discussed
with the Miele Application Technology specialists.
 If the cleaning result is subject to particularly stringent require-
ments, e.g. in chemical analysis, the operator must carry out regular
quality control to ensure that required standards of cleanliness are
being achieved.
 Mobile units, modules and inserts should only be used for the pur-
pose they are designed for.
Hollow instruments must be thoroughly cleaned, internally and ex-
ternally.
 Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
 Empty any containers or utensils before loading them.

Warning and Safety instructions
20
 The amount of residual solvents and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21°C.
 Chlorous solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 Ensure that solutions or steam containing chlorides or hydrochloric
acid do not come into contact with the stainless steel outer casing of
the machine in order to avoid any damage through corrosion.
 After any plumbing work the water pipework to the machine will
need to be vented. If this is not done, components can be damaged.
 Follow the installation instructions in the operating and installation
instructions.
Using accessories
 Only Miele accessories should be connected to this machine. They
must be suitable for the application they are required for. Consult
Miele for details on the type of accessories that can be used.
 Only use Miele mobile units, baskets and inserts with this washer-
disinfector. Using mobile units and inserts made by other manufac-
turers, or making modifications to Miele accessories can cause un-
satisfactory cleaning results, for which Miele cannot be held liable.
Any resultant damage would not be covered by the guarantee.
 Only use process chemicals which have been approved by their
manufacturer for the relevant application. The manufacturer of the
process chemicals is liable for any negative influences on the material
of the load and the machine.
