 A damaged or leaking machine could be dangerous and compro-
mise your safety. Disconnect the machine from the electrical supply
immediately and contact Miele Service.

IMPORTANT SAFETY INSTRUCTIONS
9
 Label machines which have been taken out of operation and lock
them to prevent them being switched on again without authorization.
The machine may only be put back into operation once it has been
successfully repaired by Miele Service or an authorized technician.
 Personnel operating the machine should be trained regularly. Un-
trained personnel must not be allowed access to the machine or its
controls.
 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 wash items and the machine.
 Use caution when handling process chemicals. These may contain
irritant, corrosive or toxic ingredients.
Please observe the process chemical manufacturer's safety instruc-
tions and safety data sheets.
Wear protective gloves and goggles.
 The machine is designed for operation with water and recom-
mended additive process chemicals only. Organic solvents and
flammable liquid agents must not be used as this could cause an ex-
plosion, damage rubber or plastic components in the machine and
cause liquids to leak out of it.
 The water in the wash cabinet is NOT safe to drink!
 Use caution not to inhale powder process chemicals. Process
chemicals can cause chemical burns in the mouth and throat or lead
to asphyxiation.
 Do not lift the machine by protruding parts such as the control
panel or the opened service flap as these could be damaged or torn
off.
 Do not sit or lean on the opened door. This could cause the ma-
chine to tip and get damaged or cause injury.
 Be careful when sorting wash items with sharp, pointed ends. Po-
sition them in the machine so that you will not hurt yourself or create
a danger for others.
 Broken glass can result in serious injury during loading or unload-
ing. Broken glass items must not be processed in the machine.
 The machine can get hot when in use. Use caution not to scald or
burn yourself or come into contact with irritant substances when
opening the door.
 Should personnel accidentally come into contact with toxic vapors
or process chemicals, follow the emergency instructions given in the
manufacturer's safety data sheets.

IMPORTANT SAFETY INSTRUCTIONS
10
 Mobile units, baskets, modules, inserts and the load must be al-
lowed to cool down before they are unloaded. Any water remaining in
containers could still be very hot. Empty them into the wash cabinet
before taking them out.
 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.
 Depending on the properties of the flooring and footwear worn on
it, liquids can cause a slipping hazard. Keep the floor dry where pos-
sible and take care to clean up any liquid spills straight away. Take
the necessary precautions when cleaning up hazardous substances
and hot liquids.
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.
 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.
 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 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 su-
pervisor to check foaming levels.

IMPORTANT SAFETY INSTRUCTIONS
11
 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 ap-
plication grounds, it does not imply that the manufacturer of the ma-
chine accepts liability for the effect of the chemical on the items be-
ing 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 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, such as an oxyhydrogen explosion.
 Always follow the manufacturer's instructions on storage and dis-
posal 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 dis-
cussed with Miele.
 If the cleaning result is subject to particularly stringent require-
ments, 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.
 The mobile units, baskets, modules and inserts that hold the wash
load must be used only as intended.
Hollow items must be thoroughly cleaned, internally and externally.
 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.
 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 70°F (21°C).
 Chloride 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 primed. If this is not done, components can be damaged.

IMPORTANT SAFETY INSTRUCTIONS
12
 The gaps between a built-in machine and adjacent cabinetry must
not be filled with silicone sealant as this could compromise the venti-
lation to the circulation pump.
 Follow the installation instructions in the operating and installation
instructions.
