Be careful when sorting items with
sharp pointed ends and positioning
them in the machine that you do not
hurt yourself or create a danger for
others. Sharp knives etc. should be
placed in baskets with the pointed ends
facing downwards.
When using this machine in the
higher temperature ranges, be
especially careful not to scald or burn
yourself or come into contact with
irritant substances when opening the
door. Where disinfecting agents are
used there is a danger of inhaling toxic
vapours.
Where there is a risk of toxic or
chemical substances occuring in the
suds solution (e.g. aldehyde in the
disinfecting agent), it is essential to
regularly check door seals and make
sure that the steam condensor is
functioning correctly.
Opening the machine door during a
programme interruption carries
particular risks in such circumstances.
Should personnel accidentally come
into contact with toxic vapours or
chemical agents, follow the emergency
instructions given in the manufacturer's
safety data sheets.

the load must be allowed 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.
After using the hot air drying unit,
open the door to allow the everything in
the cabinet from the load itself to the
mobile units, modules and inserts to
cool down.
Do not touch the heating elements
(under the wide area filter) during or
directly after the end of a programme,
you could burn yourself. They remain
hot for some time after the end of the
programme.
Warning and safety instructions

							If the boiler has been programmed
to "BOILER READY", be particularly
careful of hot water and steam when
opening the door. Danger of burning or
scalding. The inlet to the wash cabinet
is located, as viewed from the unclean
side, underneath the basket runner on
the left hand side.
Steam heating is permissible up to a
pressure of 1000 kPa (10 bar). This
corresponds to a water steam
temperature of 179°C.
Never clean the machine or near
vicinity with a water hose or a high
pressure hose.
The machine must be disconnected
from the mains electricity supply before
any maintenance or repair work is
carried out. Do not reconnect it until the
maintenance or repair work has been
successfully completed.
The following points should be
observed to assist in maintaining
quality standards for processing
medical devices and sensitive
laboratory glassware, and to avoid
injury to patients or damage to
equipment.
If the machine is being used for
disinfection in accordance with official
regulations on the control of epidemics,
the steam condenser and its
connections to and from the wash
cabinet must be cleaned and
disinfected whenever any repairs are
carried out or parts replaced.
If it is necessary to interrupt a
programme in exceptional
circumstances, this may only be done
by authorised personnel.
The standard of cleaning and
disinfection in the disinfection
programmes must be routinely
confirmed by the user. The process
should be validated on a regular basis,
and checked against documented
control results.Chemical disinfection
procedures should also be validated
usingchemicalor bio indicators.
For thermal disinfection, use
temperatures and temperature holding
times to achieve the required infection
prophylaxis in accordance with current
health and safety regulations.
Disinfection programmes which use
a chemical disinfecting agent at
moderate temperatures such as 65 °C
or lower are not recognised by §18 IfSG
for disinfection. They should only be
used for items which cannot withstand
the higher temperatures used by
thermal disinfection. The range of
effective disinfection is based on claims
made by the producer of the
disinfecting agent. Their instructions on
handling, use and effectiveness must
be observed. The use ofchemical
disinfection procedures is the
responsibility of the operator.
Theatre (OP) shoes should only be
cleaned and disinfected in a machine
installed specifically for this purpose.
Warning and safety instructions

							Only use chemical agents
formulated for special processes and
approved by Miele for use with this
machine. Use of unsuitable agents
could adversely affect the components
of the machine. In the event of any
damage or material deterioration
please contact your Miele application
specialist.
Pre-treatments with cleaning or
disinfecting agents can create foam, as
can certain types of soiling and
chemical agents. Foam can have an
adverse effect on the disinfection and
cleaning result.
Foam must not be able to escape
from the wash cabinet. It would hinder
the correct functioning of the machine.
Check the process used regularly to
monitor foaming levels.
To avoid the risk of damage to the
machine and any accessories used
with it caused by chemical agents,
soiling and any reaction between the
two please read the notes in "Chemical
Processes and Technology".
Where a chemical agent is
recommended on technical application
grounds (e.g. a cleaning agent), this
does not imply that the manufacturer of
the machine accepts liability for the
effect of the chemical on the items
being cleaned.
Please be aware that changes in
formulation, storage conditions etc.
which may not be publicised by the
chemical manufacturer, can have a
negative effect on the cleaning result.
When using cleaning agents and
specialised products it is essential that
the manufacturer's instructions are
followed. Chemicals must only be used
for the purpose they are designed for
and in the situation specified, to the
exclusion of other chemicals, to avoid
such dangers as chemical reactions
and material damage.
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 chemical agents, water quality etc.
are discussed with the Miele
Application Technology specialists.
If cleaning and rinsing results are
subject to particularly stringent
requirements (e.g. chemical analysis,
specialised industrial processes etc.), a
regular quality control test must be
carried out by the user to ensure that
the required standards of cleanliness
are being achieved.
Mobile units, modules and inserts
should only be used for the purpose
they are designed for.
Hollow instruments must be thoroughly
cleaned, internally and externally.
Empty any containers or utensils
before arranging them in the machine.
Do not allow any remains of acids or
solvents, and in particular hydrochloric
acid or chloride solutions, to get into
the wash cabinet. Similarly avoid any
materials with a corrosive effect. The
presence in compounds of any solvents
should be minimal (especially those in
hazard class A1).
Warning and safety instructions

							Ensure that solutions or steam
containing hydrochloric acid do not
come into contact with the steel outer
casing of the machine, to avoid any
corrosion damage.
After carrying out any work on the
mains water system, the water supply
system to the washer-disinfector must
be vented.
Otherwise, the components in the
machine may become damaged.
Please follow the advice on
installation in these instructions and the
separate Installation Instructions.
Using accessories
Only use genuine Miele original
accessories with this machine. Consult
Miele on the type and application of

–
laboratory equipment used in
micro-biology and biotechnology.
The type of laboratory equipment which
can be processed ranges from
evaporating dishes to centrifugal test
tubes.Processing medical devices and
laboratory equipment by machine
achieves reproducible results, and
should be used in preference to
processing them by hand.
Where disinfection is required for the
protection of staff and/or patients, a
thermal disinfection programme, e.g.
the DESIN vario TD programme, should
be selected.
The parameters for thermal disinfection
according to EN ISO 15883-1 (A
0concept) vary depending on the
disinfection standard required. They
are 80 °C (+ 5 °C, - 0 °C) with a 10 min
holding time (A
0600) or 90 °C (+ 5 °C,
- 0 °C) with a 5 min holding time (A
03000). An A0value of 3000 is suitable
for deactivating the HBV virus.
National health and safety regulations
regarding disinfection must also be
observed.
The cleaning programme as well as any
chemical agents must be chosen
according to the type of soiling and
load being processed.
The agents used for processing the
products should be selected to suit the
level of cleaning required as well as the
method of analysis used.
Intended Use
9 
						

							The cleaning result must ensure that
the instruments can be disinfected
correctly, that no residues are left
behind, that subsequent sterilisation
can be carried out and that the
instruments can be used again safely.
Medical devices are best processed
using the DESIN vario TD programme,
or the OXIVARIO programme where
applicable.
The use of a suitable carrier (mobile
unit, module, insert etc.) is important to
ensure the adequate cleaning of the
load. Examples are given in the section
"Areas of application".
The washer-disinfector is programmed
to carry out the final rinse with mains
water or with processed water of a
quality to suit the application (e.g. aqua
destillata, purified water, de-ionised
water, demineralised water). The water
quality is of particular importance for
applications requiring analytically clean
laboratory glassware.
This machine complies with EN ISO
15883 for validation purposes.
