Safety instructions and warnings
5 
						

							~A damaged appliance can
endanger your safety. Immediately turn
off the machine at the power switch and
contact the Miele Service Department.
~Machine operators must be trained
on a regular basis. Untrained personnel
must not be allowed access to the
machine or its controls.
~Always exercise caution when
handling chemicals for this machine
(cleaner, neutralizer, rinsing agent,
etc.). Some of these products contain
corrosive and irritating substances.
NEVER use organic solvents or
flammable liquids due to the risk of
explosion.
Always follow proper safety technique.
Use protective glasses and gloves.
Always follow the manufacturer's safety
recommendations when using process
chemicals (see material safety data
sheets).
~Avoid inhaling powdered products.
Swallowing process chemicals can
result in chemical burns to the mouth
and throat and suffocation.
~The water in the wash cabinet is
NOT safe to drink.
~Do not stand, sit or lean on the open
door. The appliance might tip over or
be damaged.
~Take care when sorting standing
items with sharp pointed ends. Position
them in the machine so that you will not
hurt yourself or create a danger for
others.
~When operating this machine,
beware of the high temperatures
involved. If you bypass the electrical
lock to open the door, there is the
danger of scalding and heat or
chemical burns. If disinfectants have
been used, there is also the danger of
inhaling toxic vapour.
~If you are exposed to toxic vapours
or processing chemicals, consult the

sheets for emergency procedures.
~Always allow baskets, inserts and
the washload to cool down. Empty any
water from hollow items into the wash
cabinet.
~Do not touch the heating elements
when you open the door at the end of a
program. They remain hot for quite a
few minutes after the program has
ended and can cause burns.
~NEVER hose down the machine or
the immediate vicinity, e.g., with a water
hose or pressure washer.
~Before servicing the machine,
disconnect it from the power supply by
either removing the fuse, unplugging
the unit or manually tripping the circuit
breaker.
Safety instructions and warnings

							The following points should always
be observed to assist in maintaining
quality standards when processing
medical devices and critical items, to
protect patients and to avoid damage
to property.
~Only authorized persons may
interrupt a program and only in
exceptional cases.
~It is the responsibility of the operator
to routinely check that the required
cleaning and disinfection standards are
being met, therefore, process results
need to be regularly tested and
documented, both thermoelectrically
and through inspection. For
thermochemical processes, additional
testing is required using chemical or
biological indicators.
~For thermal disinfection, the
appropriate temperatures and holding
times, as required by microbiological
and public health standards and
guidelines, must be used to achieve the
required degree of infection control.
~If toxic chemicals may be present in
the wash cabinet (e. g. aldehydes in
the disinfectant), beware of this risk
when interrupting a program and
opening the machine. The door seal
and steam condensor must always be
checked for soundness.
~Under certain circumstances, the
processing chemicals can cause
damage to the appliance. Consult Miele
Customer Service for
recommendations. For concerns
involving possible damage to the
appliance or materials, please consult a
Miele Application Specialist.
~Pre-treating (e. g. with cleaning
agents or disinfectants), some types of
soiling and the interaction of certain
processing chemicals can cause
foaming. Suds can have an adverse
effect on the results obtained. For
pre-treatment and/or cleaning only use
low-sudsing detergents which have
been approved by Miele.
~The recommendation to use process
chemicals (for example, detergents)
does not mean that the machine
manufacturer accepts liability for how
these process chemicals may affect the
items involved. Note that formulation
changes, storage conditions, etc., that
are not disclosed by the manufacturer
may alter the cleaning results obtained.
Safety instructions and warnings
7 
						

							~When using cleaning agents and
special-purpose products, comply
strictly with the product manufacturer's
instructions. Use cleaning agents only
for the applications intended by the
manufacturer so as to avoid possible
chemical reactions (such as explosive
oxyhydrogen gas reactions).
~The appliance is designed only for
operation with water and additive
cleaning agents. Organic solvents must
NOT be used, as there is the danger of
explosion and/or damage (Note: while
certain organic solvents do not carry a
risk of explosion, they may nonetheless
cause other problems, such as damage
to rubber and synthetic parts).
~For critical applications, where very
high processing-quality requirements
have to be met, it is strongly
recommended that all process-related
factors (cleaning agents, water quality,
etc.) be discussed in advance with
Miele's Application Specialist.
~Only use mobile units, modules and
inserts as intended by the
manufacturer.
Hollow items must be positioned for full
exposure to wash water.
~Empty all containers and hollow
utensils before loading them.
~Ensure that no acid or solvent
residues, especially hydrochloric acid
or chloride solutions, get inside the
wash cabinet. This also applies for
corrosive ferrous material.
Solvents combined with contaminants
(especially from hazard class A1)
should be present in trace amounts
only.
~To avoid corrosion damage, make
sure the stainless steel housing does
not come into contact with
solutions/steam containing hydrochloric
acid.
~Whenever work is conducted on the
tap water network, the water supply line
to the machine must be cleared of air.
Failure to do so can result in damage to
the water softener.
~Please be sure to follow the
installation instructions in this manual
and in the separate installation manual.

							Using accessories
~Whatever the application, only Miele
accessories should be connected to
this machine.
~Only Miele mobile units, modules
and inserts should be used. If Miele
accessories are altered in any way, or
equipment from another manufacturer
is used, Miele cannot ensure the
cleaning and disinfection results.
Damage or injury caused in this way
are excluded from the warranty.
~Only use process chemicals that are
approved by their manufacturer for the
application involved. Any negative
effects on items and the machine itself
are the liability of the chemical
manufacturer.

							The Miele washer-disinfector is
designed to clean, rinse and thermally
disinfect re-usable equipment.
Always comply with the particular
manufacturer's instructions
(EN ISO 17664).
Examples of items that can be
processed in this appliance are
instruments, suction equipment,
transfer instruments, etc.
For standardized results, it is preferable
to machine-wash equipment.
When disinfection is required, the
preference is for thermal disinfection,
e. g., using the Disinfection vario
program.
According to the A
0concept under
EN ISO 15883-1, thermal disinfection
occurs at 90 °C (+ 5 °C, - 0 °C) and a
holding time of 5 min (A
03000). The
efficacy standard A
03000 includes the
inactivation of HBV.
Regional and/or other official directives
may apply (e. g., §18 of the IfSG for
Germany).The cleaning parameters should always
be optimally matched to the type of
soiling and items involved.
Processing chemicals are to be
selected to suit the particular cleaning
needs involved.
For re-usable items to be safe for
continued use, the cleaning result must
meet certain minimum standards for
disinfection, sterilization and residue
levels.
Re-usable products are best cleaned
using the Disinfection vario program.
Also important for acceptable cleaning
results on equipment is the use of
suitable loading accessories (baskets,
modules, inserts). See the section on
"Applications" for examples.
The washer-disinfector is designed to
rinse with tap water or processed water
(e.g., distilled water, pure water,
deionized water, demineralized water)
depending on the quality required for
your application(s).
Under EN ISO 15883, this
washer-disinfector is suitable for
process validation.
