15
 A damaged or leaking machine is dangerous and poses a safety
hazard. Immediately disconnect the machine at the power switch and
contact the Miele Service Department.
 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 by an appropriately qualified
specialist.
 Personnel operating the machine should be trained on a regular
basis. Untrained 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 load items and the machine.
 Always exercise caution when handling the process chemicals for
this machine. These products may contain irritant, corrosive or toxic
ingredients.
Always comply with safety requirements and the manufacturer's
safety instructions (see safety data sheets)!
Use protective eyewear and gloves!
 The machine is designed to operate with water and the

Warning and Safety Instructions
16
 Should personnel accidentally come into contact with toxic
vapours or processing chemicals, consult the manufacturer's safety
data sheets for emergency procedures.
 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.
 For thermal disinfection, use temperatures and 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
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.
 Cleaning detergents containing chlorine can damage the
elastomers of the machine.
If the use of cleaning detergents containing chlorine is required, a
maximum temperature of 167°F (75°C) in the “Main wash” 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
containing chlorine may not be used!

Warning and Safety Instructions
17
 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 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
machine.
 The process must be checked regularly in order to detect any
foaming.
 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 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 process chemicals, always consult the instructions
issued by individual manufacturers. Process chemicals must only be
used for the purpose for which they are designed by the
manufacturer to avoid any material damage or the occurrence of very
strong chemical reactions.
 Always follow the relevant manufacturer's instructions on storage
and disposal of process chemicals.
 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.
 If the cleaning result is subject to particularly stringent
requirements, 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 carts, 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.

Warning and Safety Instructions
18
 Empty all containers and hollow utensils before loading them into
the machine.
 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 (70°F).
 Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 To avoid corrosive damage, make sure the stainless steel housing
does not come into contact with solutions or steam containing
hydrochloric acid.
 After any plumbing work the water pipework to the machine will
need to be vented. If this is not done, components can be damaged.
 The gaps between a built-in machine and adjacent cabinetry must
not be filled with silicone sealant as this could compromise the
ventilation of the circulation pump.
 Follow the installation instructions in the operating instructions and
in the installation instructions.
Safety with children
 Children must be supervised in the vicinity of the machine. Do not
allow children to play with the machine. Among other hazards, they
could get locked inside it.
 Children must not use the machine.
 Keep children away from process chemicals! These can cause
burning in the mouth, nose and throat if swallowed, or inhibit
breathing. Keep children away from the machine when the door is
open. There could still be residual process chemicals in the cabinet.
Observe the safety data sheets for the process chemicals and seek
medical advise immediately if a child has swallowed process
chemical or got it in the eyes.
Using components and accessories
 Only Miele accessories should be connected to this machine for
the appropriate application. Consult Miele for details on the type of
equipment to use.
 Only use Miele wash carts, baskets, modules and inserts with this
machine. Using wash carts, baskets and inserts made by other
