13
 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.
 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 application you are using. The manufacturer of
the process chemicals is responsible for any negative influences on
the material of the load is made from and for any damage they may
cause to 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
recommended process chemicals only. Organic solvents or
flammable liquid agents must not be used in it!
This could cause an explosion, property damage due to the
destruction of rubber and plastic components, and the resulting
leakage of liquids.
 The water in the cabinet must not be used as drinking water.
 Take care not to inhale powder cleaning detergents. Swallowing
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
machine to tip or become damaged.
 Be careful when sorting items with sharp, 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
unloading. Broken glass items must not be processed in the machine.
 The machine can get hot when in use. Be careful 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
vapours or processing chemicals, consult the manufacturer's safety
data sheets for emergency procedures.

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.

Warning and Safety Instructions
15
 To prevent material damage to the machine and accessories used
from the effects of process chemicals, soiling and their interaction,
follow the notes in chapter "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 follow the instructions of
the chemical's manufacturer. The process chemicals must only be
used for the application it is designed for and in the situation
specified to avoid material damage and such dangers as a severe
chemical reaction (e.g. an explosive oxyhydrogen gas reaction).
 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.
 For applications that demand especially stringent cleaning and
rinsing results, the operator must ensure that quality control occurs
on a regular basis to meet the standards involved.
 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.
 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.
 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.

Warning and Safety Instructions
16
 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
