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.

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.
7
Safety instructions and warnings
When using cleaning agents and

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.

Description of the machine
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
concept under
0
EN ISO 15883-1, thermal disinfection
occurs at 90 °C (+ 5 °C, - 0 °C) and a
holding time of 5 min (A
efficacy standard A
3000). The
0
3000 includes the
0
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.
10
Description of the machine
High -level disinfection
The washer-disinfector cleans items,
and in the disinfection program,
simultaneously thermally disinfects at
93°C/200°F.
Areas of effectiveness are physical
removal or thermal inactivation of
vegetative bacteria including
mycobacteria, fungi, fungal spores and
viruses. These catergories include the
Mycobacterium tuberculosis and the
Enterococcus faecium.
Important: Only the program labelled
"disinfection" disinfects! Only use this
program when handling contaminated
items. All other programs are designed
to clean items without disinfecting.
The washer-disinfector achieves
high-level disinfection as defined by
the Spaulding categorization.
The Spaulding category high-level
disinfection is the same type of means
as in the sterilant category except that
the use pattern is different. The sterilant
is used as a high-level disinfectant by
e.g. reducing the exposure time within
its effective range of tuberculocidal,
virucidal and bactericidal action.
Instruments suitable for processing
in the washer-disinfector
In general, only high quality stainless
steel items are suitable for processing
in the washer-disinfector. All items to be
cleaned and disinfected in the
washer-disinfector should have the
following properties:
heat resistance to a temperature of
–
95°C/203°F
corrosion resistance in the presence
–
of heat and alkalinity.
The heat retention capacity of stainless
steel allows for fast drying. Plastic has a
lower heat retention capacity, thus
requiring a longer drying time. In this
case, a slightly extended waiting period
of 5-15 minutes may be necessary after
the disinfection cycle.
Aluminum items may discolour during
the cleaning process. Aluminum has
only a limited suitability for processing
in the washer-disinfector.
Carbon steel and chrome-plated items
may corrode during the cleaning
process. Processing these types of
items in the washer-disinfector is NOT
recommended.
Hand pieces, drill bits, grinders, root
canal instruments or other rotating
items are not suitable for the
washer-disinfector. Do not process
them in the washer-disinfector.
11
Description of the machine
Do not clean fiberoptics or electrical
equipment and components in the
washer-disinfector.
Rhodium coated mirrors must be
arranged so that their surfaces do not
suffer any mechanical damage. Not all
specula with glass are suitable for
machine treatment.
If you have questions regarding
whether an item is suitable for
processing in the washer-disinfector,
please seek the advice of the item
manufacturer.
Water Quality
Good water quality is essential for
processing items in the
washer-disinfector, otherwise, item
corrosion may result.
Poor water quality consists of, but is not
limited to, high concentrations of
chlorides (over 50 ppm). High chloride
levels will cause even high quality
stainless steel items to rust when
processed in the washer-disinfector.
Other effects that may be noticed are
tarnishing or "blueing" of items due to
dissolved minerals in the water.

Caring for the environment
Disposal of packing materials
The packing materials help protect the
appliance during transport. They have
been selected with an eye to
environmental compatibility and
efficient disposal and should be
recycled.
Returning packaging to the materials
cycle saves raw material and reduces
waste.
Disposing of your old
appliance
Old electric and electronic equipment
often contains valuable materials but
they may also contain harmful
substances that were necessary for
safe use. Improperly disposing of these
items in your household waste can
harm human health and the
environment. This is why it is important
to NEVER dispose of your old
appliance with the regular household
garbage.
Instead, please contact your local
community waste collection point to
return and recycle electric and
electronic appliances.
If the appliance is being stored for
disposal, please make sure it has been
child-proofed.

Before using for the first time
Before using the machine for the first
time please pay special attention to
the following points:
Detailed information on these points
can be found in the relevant section
of the Operating Instructions.
Load the machine carefully.
Arrange the load so that water will
come into contact with all surfaces.
Concealed surfaces will not be
cleaned.
The spray arms must not be blocked by
any items.
Set the water softener
The water softener must be set to the
water hardness level of your area.
Contact your local water authority to
find your water hardness level in parts
per million (ppm) or grains per gallon
(gr/gal).
The salt reservoir must be filled first
with water and then with reactivation
salt.
Filling the salt reservoir with cleaning
agent by mistake will cause serious
damage to the water softener. Please
check every time before refilling that
the package contains reactivation salt.
Add rinsing agent
Inadvertently filling the rinsing agent
reservoir with cleaning agent
(including liquid cleaning agents
and dishwashing soap) will cause
serious damage to the reservoir.
Adding detergent
Follow the dosage recommendations of
the cleaning agent manufacturer.
The filter combination at the base of
the wash cabinet and the spray arms
must be clean.
Regular checking and cleaning is
essential.
Only use detergents suitable for use
in disinfecting washers.
Do not use detergents formulated for
use in domestic dishwashers.

Water softener
In order to provide good cleaning
results, the machine requires a supply
of soft water (water that is low in
calcium and magnesium). If hard tap
water is used, it can leave a white
mineral deposit build-up on the items
and the machine itself, therefore, tap
water with a hardness of 4 °d
(0.7 mmol/l) or more must be softened.
The built-in water softener is designed
for this purpose.
In order to function properly, the
–
water softener requires a supply of
reactivation salt.
– The cleaner must be correctly
programmed to match the hardness
of the tap water supply.
– Your local water authority will provide
information about the hardness of the
tap water in your area.
If the water hardness is known to
fluctuate (e. g., 8 - 17 °d), always
program for the highest value (in this
instance 17 °d).
How to program the water
softener
Use the "ON/OFF" button to switch off
^
the machine.
Turn the program selector to the
^
12 o'clock position f.
Simultaneously press and hold the
^
"Display" ß and "Start" 6 buttons,
while turning the machine on with the
"ON/OFF" button.

Water softener
How to fill the salt reservoir
Only use special, coarse-grained, Miele
reactivation salt with a grain size of
1 - 4 mm. NEVER use other types of
salt, such as table salt, cattle salt or
de-icing salt. These salts can contain
components that are insoluble in water
and could damage the water softener.
The salt reservoir holds
approximately 2.5 kg salt.
Inadvertently filling the salt
,
reservoir with detergent WILL
damage the water softener.
Before filling the reservoir, always
make sure that you are using
reactivation salt.
^ Remove the bottom basket from the
machine.
^ Unscrew the salt reservoir cap.
Before filling the salt reservoir for the
first time:
fill the reservoir with approximately
2.5 liters of water, so that the salt
can dissolve properly. Once the
washer-disinfector has been
operated, there will always be
enough water in the reservoir.
Place the provided funnel accessory
^
over the salt reservoir.
^ Carefully fill the reservoir with
reactivation salt.
Some displaced water will run out - this
is normal.
^ Wipe any residual salt off the screw
threads on the reservoir.
^ Screw the cap back on completely.
^
Immediately after this step, start the
"Rinse" program, to remove any
traces of salt from the inside of the
machine.
Note: There may be a delay of a few
minutes before the "Rinse" program
starts - this is normal. It simply
means the water softener is being
reactivated as needed.

cycle.
