to the machine or its controls.
� Take care when handling chemical
agents such as cleaning agent,
neutralising agent, rinsing agent etc.
These may contain irritant or corrosive
ingredients.
Please follow the manufacturer's safety
instructions. Wear protective gloves
and goggles. With all chemical agents,
the manufacturer's safety instructions
and safety data sheets must be
observed.
� The washer-disinfector is designed
for operation with water and
appropriate chemical agents only.
Organic solvents and flammable liquid
agents must not be used in this
machine.
These could cause an explosion,
damage rubber and plastic
components in the machine, and cause
liquids to leak out of the machine.
� The water in the cabinet must not be
used as drinking water.
� 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.
� Please be aware that the
washer-disinfector may be operating at
high temperatures. If the door is
opened by circumventing the lock there
is the danger of burning, scalding or
chemical burning. If 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 chemical agent
manufacturer's safety data sheets.
� Mobile units, modules, inserts and
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.
Warning and safety instructions
7
� 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 right 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 hose or a pressure
washer.
� 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 reprocessing
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 for medical devices must
be routinely confirmed by the user. The
process must be thermo-electrically
validated on a regular basis, and
checked against documented control
results. Chemical disinfecting
procedures must also be validated
using chemical or 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.
� Medical devices are reprocessed by
thermal disinfection. Items which are
not heat-resistant, e.g. operating
theatre (OP) shoes, can be
reprocessed with the CHEM-DISIN
programme with the addition of a
chemical disinfection agent.
The range of effective disinfection is
based on claims made by the producer
of the disinfecting agent, whose advice
regarding handling, use and
effectiveness must be observed. This
type of chemo-thermal procedure is not
suitable for reprocessing medical
devices.
� Chemical agents could, under
certain conditions, cause damage to
the washer-disinfector. Follow the
recommendations of the chemical
agent manufacturer. In the event of any
damage or material deterioration
please contact Miele.
Warning and safety instructions
8
� Do not use any abrasive chemical
agents in washer-disinfectors as these
will cause erosion to machine
components (e.g. spray arm bearings).
If using abrasive chemical agents in the
manual pre-preparation of containers or
instruments, ensure that no trace of
these remain prior to reprocessing in
the washer-disinfector.
� 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.
� The process used should be
checked regularly by the supervisor 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 a chemical agent it is
essential that the manufacturer's
instructions are followed. The chemical
agent 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
explosive chemical reaction (e.g. an
explosive oxyhydrogen gas reaction).
� 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 Miele.
� If cleaning and rinsing results are
subject to particularly stringent
requirements (e.g. chemical analysis),
a regular quality control test must be
carried out by the supervisor 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.
� The amount of residual solvents and
acids on items going into the cabinet
should be minimal. This applies in
particular to hydrochloric acid or
chloride solutions and to items
containing iron that can rust or corrode.
The presence in soiling of any solvents
should be minimal (especially those in
hazard class A1).
Warning and safety instructions

Warning and safety instructions
10
Re-usable medical devices, laboratory
equipment and accessories can be
cleaned, rinsed, disinfected and dried
in this Miele washer-disinfector.
Follow the medical device and
laboratory equipment manufacturer's
instructions (according to EN ISO
17664) and local and national
regulations and guidelines, on how to
reprocess their items by machine.
Examples of application areas:
– surgical instruments,
– minimally invasive surgical
instruments,
– anaesthetic and intensive care
instruments,
– baby bottles and teats,
– maintenance and waste containers,
– operating theatre shoes,
or
– laboratory equipment used in
research and development,
– laboratory equipment used in areas
of analysis and specimen taking,
– laboratory equipment used in
micro-biology and biotechnology.
The type of laboratory equipment which
can be reprocessed ranges from
evaporating dishes to centrifugal test
tubes.
Reprocessing medical devices and
laboratory equipment by machine
achieves reproducible results, and
should be used in preference to
reprocessing 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.
- Except for operating theatre (OP)
shoes which are not heat-resistant, for
which the CHEM-DISIN programme
should be used.
The parameters for thermal disinfection
according to EN ISO 15883-1 (A0
concept) vary depending on the
disinfection standard required. They
are 80 °C (+ 5 °C, - 0 °C) with a 10 min
holding time (A0 600) or 90 °C (+ 5 °C,
- 0 °C) with a 5 min holding time (A0
3000). An A0 value of 3000 is suitable
for deactivating the HBV virus.
National health and safety regulations
regarding disinfection must also be
observed (CfPP 01-01, Part D and
Harmonised EU Norm EN 15883-2 in
the UK).
The cleaning programme as well as any
chemical agents must be chosen
according to the type of soiling and
load being reprocessed.
The agents used for reprocessing the
products should be selected to suit the
level of cleaning required as well as the
method of analysis used.
Intended Use
11
The cleaning result must ensure that
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 reprocessed
using the DESIN vario TD programme,
or the ORTHOVARIO or OXIVARIO
programme where applicable.
The use of a suitable carrier (mobile
unit, module, insert etc.) is important to
ensure the adequate cleaning of
instruments and medical devices.
Examples are given in the section
"Areas of application".
The washer-disinfector is programmed
to carry out the final rinse with mains
water or processed water (e.g. Aqua
destillata, pure water, de-ionised water,
demineralised water in the quality
required by the application). The water
quality is of particular importance for
applications requiring analytically clean
laboratory glassware.
The machine qualifies for the validating
of processes in accordance with EN
ISO 15883.
User profile
Daily operatives
Operatives using the machine daily
should be familiar with the basic
functions of the machine and its loads
and trained on a regular basis. They
require basic knowledge about how to
reprocess medical devices by
machine.
Generally they would be using the
machine in Operating levels A and C.
Supervisory level
More advanced functions such as
interrupting or cancelling a programme
requires more in-depth knowledge
about machine reprocessing of medical
devices.
This level of functionality is carried out
in Operating level B.
Service and Administration
Changes to reprocessing methods and
alterations to the washer-disinfector,
e.g. concerning the type of accessories
used in it or the conditions in which the
machine is used require additional
knowledge about the machine.
Validation also requires additional
knowledge about how to reprocess
medical devices, which procedure to
use and any Standards and regulations
that may apply.
Service and validation work is carried
out using Operating level D.

The automatic mobile unit recognition
system allocates a programme to a
mobile unit. The mobile units must be
coded with a magnetic strip (via a Bit
combination).
The programme allocated for a coded
mobile unit is available in operating
level C.
After a coded mobile unit has been put
into the machine and the door closed,
the automatic mobile unit recognition
system will select the allocated
programme.
The coding of the mobile units and
the allocation of programmes in the
Profitronic control unit are described
in the Programming manual for the
washer-disinfector.
Make sure that there are no
small metallic objects or instrument
parts attracted to the magnetic strip,
in particular to the underside of it.
Any metallic objects on the strip can
result in the coding being incorrectly
read.
Make sure that you code mobile
units with side coupling with a track
where the sixth magnet is set to 1.
Mobile units without side coupling
must be coded with a track without
the sixth magnet.
The magnet strips for PG 8527 / PG
8528 washer-disinfectors must have
black magnets.
Automatic mobile unit recognition
27
This washer-disinfector can be fitted
with a variety of mobile units, which can
be equipped with a variety of modules
and inserts depending on the type and
shape of items requiring cleaning and
disinfection.
Select mobile units, modules and
inserts which are appropriate for the
application.
Notes on the individual areas of
application and examples of loading
are given on the following pages.
Before starting a programme you
should carry out a visual check on
the following:
– Is everything correctly
loaded/connected for cleaning?
– Are the spray arms clean and do
they rotate freely?
– Is the flat filter clean? Remove any
coarse soiling and clean it, if
necessary.
– Is the flat filter positioned horizontally
so that it forms a flush seal with the
wash cabinet?
– Is the adapter connecting the water
supply to the spray arms/jets
correctly connected?
– Are all chemical containers
sufficiently filled?
At the end of each programme:
– Carry out a visual check of the load
for cleanliness.
– Check that all hollow shafted
instruments are still securely located
on their jets.
Any hollow instruments that have
become disconnected from their
adapters during reprocessing must
be reprocessed again.
– Check that the lumen of hollow
instruments are free of obstruction.
– Check that jets and connectors are
securely held in position in the
baskets or inserts.
Protein test
Cleaning results should be subjected to
periodic protein tests, e.g. with the
Miele test kit.
Areas of application
28
Loading the machine
– Arrange the load so that water can
access all surfaces. This ensures
that it gets properly cleaned.
– Do not place items to be cleaned
inside other pieces where they may
be concealed.
– Hollow instruments must be
thoroughly cleaned, internally and
externally.
– Ensure that instruments with long
narrow hollow sections can be
flushed through properly before
placing them in inserts or connecting
them to jets.
– Hollow vessels should be inverted
and placed in the correct mobile
units, modules and inserts to ensure
that water can flow in and out of
them unrestricted.
A cover can be used to reduce the
risk of glass breakage during the
wash process.
– Lightweight items should be secured
with a cover net (e.g. an A 6) and
small items placed in a mesh tray to
prevent them blocking the spray
arms or being attracted by the
magnetic strip on the automatic
mobile unit recognition system.
– Deep-sided items should be placed
at an angle to make sure water runs
off them freely.
– Tall, narrow pieces should be placed
in the centre of the baskets. This
ensures good water coverage.
– Mobile units with an adapter must
engage correctly.
– Modules must be correctly
connected in the mobile unit.
– The spray arms must not be blocked
by items which are too tall or which
hang down in their path. If in doubt,
test for free movement by manually
rotating the spray arms.
– It is advisable to use only instruments
made of special application steel
which are not susceptible to
corrosion.
– Instruments which cannot withstand
high temperatures should be
chemically cleaned and disinfected.
Disposable instruments must not
be put into the machine for
reprocessing.
For validation purposes it is
essential to follow the loading
instructions given on the template.
Preparing the load
Empty all containers before loading into
the machine (paying particular attention
to regulations regarding infectious
diseases and epidemics).
Ensure that acids and residual
solvents, especially hydrochloric
acid or chlorides, cannot get into the
wash cabinet.
Unloading instruments
Instruments should be unloaded dry
ready for further processing.
Areas of application
29
Surgical instruments (OP)
Surgical instruments should be stored
for as short a time as possible before
machine reprocessing - and for no
longer than 2 hours.
It is best to reprocess surgical
instruments using the DES-VAR-TD
programme.
The OXIVARIO or ORTHOVARIO
programme should be used for
instruments where there is a long delay
between the time they are used and the
time they can be reprocessed. See
"Special processes" at the end of this
booklet.
Disinfection of surgical instruments and
of those used for minimally invasive
surgery should take place thermally.
De-ionised water with a conductivity
level of ~ 15 �S/cm (microsiemens per
centimetre) should be used for the final
rinse whenever possible to ensure no
marks are left on the load and to avoid
corrosion. If the water used contains
more than 100 mg chloride/litre there is
a risk of corrosion.
When reprocessing narrow lumen
instruments e.g. those used in
minimally invasive surgery, an
intensive internal cleaning result is
imperative. The DES-VAR-TD and
OXIVARIO programmes are the only
ones which offer a thorough enough
level of cleaning for this. It is essential
that instruments are loaded as directed
and that the cleaning agent used is
suitable for the programme and for the
sensitive instruments being
reprocessed.
The final rinse must be carried out with
de-ionised water with a conductivity
level of ~15 �S/cm (microsiemens per
centimetre).
Instruments with very narrow lumen
must be manually pre-rinsed where
necessary. Follow the instrument
manufacturer's instructions on how
to handle them.
Most OP containers can be disinfected
thermally in the CONTAINER
programme. If anodised aluminium
containers are being reprocessed,
de-ionised water must be used for the
wash cycles and the final rinse.
These containers must not be
reprocessed with an alkaline cleaning
agent in a 93 °C programme with 10
minutes holding time (according to
§ 18 IfSG).
For reprocessing OP containers to an
A0=600 disinfection standard, the
CONTAINER-600 programme must be
programmed in retrospectively by
Miele.
Mobile surgical insturments and
containers are supplied with their
own operating instructions.
Areas of application
30
Ophthalmology
The E 929/1 mobile injector unit is
designed for the cleaning and
disinfecting of opthalmic instruments.
The final rinse should be carried out
using de-ionised water with a
conductivity of ~15 �S/cm
(Microsiemens per centimetre). In terms
of quality, the water used for the final
rinse must contain minimal amounts of
endotoxins and pyrogens.
The top level is fitted with various
connections for hollow instruments, e.g.
rinsing and suction hand pieces, and
cannulae.
Instruments are secured to the hose
connectors in the mobile injector unit
using the silicone holders and
connectors in the rack.
The lower level of the mobile injector
unit is designed to take E 441/1 inserts
or E 142 mesh trays for reprocessing
solid instruments.
Plastic fibre cover nets must not
be used in washer-disinfectors
which are used to reprocess hollow
opthalmic instruments with narrow
lumens.
The mobile injector unit for
ophthalmic instruments is supplied
with its own operating instructions.
The E 929/1 mobile injector unit
for opthalmic instruments may only
be used in washer-disinfectors
which do not have a built-in
dispensing system with a flow rate of
465 ml/min.
Washer-disinfectors fitted with
DK+WRG must not be used for
reprocessing opthalmic instruments.
Areas of application
31
Anaesthetic instruments (AN)
Anaesthetic instruments should be
thermally disinfected using the
DES-VAR-TD-AN programme.
If the process is not to be followed
by sterilisation, the load should be
dried completely to avoid the
development of water-borne
bacteria.
A sufficient drying time is, therefore,
absolutely essential.
Mobile units for anaesthetic
instruments are supplied with their
own operating instructions.
Areas of application
32
Baby bottles (BC)
Baby bottles in E 135 containers can be
placed in the two lower levels of mobile
unit E 935/1 and then cleaned and
disinfected in this washer-disinfector. In
addition, E 364 containers with
wide-necked teats and E 458
containers with screw-cap teats can be
placed in the upper level of the mobile
unit.
– Ensure the level marker on the
bottles is machine-washable.
– If there is a delay of 4 hours or more
before bottles can be washed, fill
them with water to prevent residues
from drying on.
If the process is not to be followed
by sterilisation, the load should be
dried completely to avoid the
development of water-borne
bacteria.
A sufficient drying time is, therefore,
absolutely essential.
Inserts for baby bottles and teats are
supplied with their own operating
instructions.
Loading in E 935/1 mobile unit
Lower level with 4 x E 135 containers
Upper level with 3 x E 135 containers
The containers must be arranged so
that the two blocked off corners are
in the positions marked with
crosses, as shown.
If bottles were to be placed in these
positions, water would not be able to
access the inside of the bottles
properly and cleaning results would
be impaired.
Areas of application
33
Operating theatre shoes (OS)
OP shoes made of thermolabile
material and/or insoles can be cleaned
and disinfected chemo-thermally at
60 °C with the CHEM-DISIN
programme.
A thermal disinfection process
(SHOE-TD-75/2 programme) can be
used if thermostability has been
confirmed by the manufacturer.
For reprocessing operating theatre
(OP) shoes to an A0=60 disinfection
standard, the SHOE-60 programme
must be programmed in retrospectively
by Miele.
To establish the effectiveness of
chemical disinfecting agents for
disinfection consult the manufacturer.
Theatre (OP) shoes should only be
cleaned and disinfected in a
machine installed specifically for
this purpose.
A risk evaluation should be carried
out by the user when using other
applications in addition to the
preparation of OP (Theatre) shoes in
the washer-disinfector.
Mobile unit E 975/1 with a suitable
insert can be used for this purpose,
e.g.
– Insert E 930 for up to shoe size 43
can be placed in the lower level of
mobile unit E 975/1,
– Insert E 931 for up to shoe size 48.
A large amount of fluff can build up
in the machine when cleaning
theatre shoes. The filters in the wash
cabinet should therefore be
checked regularly, and cleaned
when necessary. See "Maintenance,
Cleaning the filters in the wash
cabinet".
Areas of application
34
Laboratory glassware (LG)
Wide-necked laboratory glassware, e.g.
beakers, wide-necked Erlenmeyer
flasks and Petri dishes, and cylindrical
shaped items e.g. test tubes, can be
cleaned and rinsed, internally and
externally, by the action of the rotating
spray arms. They can be arranged in
full, half and quarter inserts in an empty
mobile unit with spray arms.
Narrow-necked items e.g. narrow-
necked Erlenmeyer flasks, conical
flasks, measuring flasks and pipettes,
require mobile injector units or injector
modules.
The following instructions relate only to
basic preparation and loading of
glassware.
Loading the machine
– Petri dishes and similar should be
placed in the correct insert with the
soiled side facing the centre.
– Pipettes should be placed with the
tip facing downwards.
– Quarter inserts should be placed as
close to the middle of the unit as
possible.
– Glass items must not get in the way
of the door opening.
Preparing the load
� Empty all glassware before loading
into the machine (paying particular
attention to regulations regarding
epidemics).
Ensure that acids and residual
solvents, especially hydrochloric
acid or chlorides, cannot get into the
wash cabinet.
� Remove all agar residues from Petri
dishes.
� Remove blood clots and residues
from test tubes, etc.
� Remove all stoppers, corks, labels,
sealing wax residues, etc.
� Small parts - such as stoppers and

General notes
Problem How to resolve it
If seals, hoses and plastics in the
washer-disinfector suffer damage they
will not be water-tight and will not
function correctly.
– Establish the cause of the damage
and rectify it.
See information regarding "Chemical
agents“, "Soiling“ and "Reaction
between chemical agents and soiling“.
Heavy foaming during a programme
affects cleaning and rinsing results.
Foam escaping from the wash cabinet
can cause damage to the
washer-disinfector.
Cleaning processes cannot be
regulated and validated where there
has been a build-up of foam.
– Establish the cause of the foam and
rectify it.
– Check the process used regularly to
monitor foaming levels.
See information regarding "Chemical
agents“, "Soiling“ and "Reaction
between chemical agents and soiling“.
Corrosion to stainless steel in the wash
cabinet and to accessories can give
them a different appearance:
– Rust (red marks / discolouration),
– black marks / discolouration,
– white marks / discolouration (etched
surface).
Corrosive pitting can lead to the
washer-disinfector not being
water-tight. Depending on application
corrosion can influence cleaning and
rinsing results (laboratory analysis) or
cause corrosion to stainless steel items
in the cabinet.
– Establish the cause of the corrosion
and rectify it.
See information regarding "Chemical
agents“, "Soiling“ and "Reaction
between chemical agents and soiling“.

Chemical agents
Problem How to resolve it
The ingredients in chemical agents
have a strong influence on the longevity
and functionality (throughput) of the
dispensing system. The dispensing
system (hoses and pumps) should be
set up for a particular type of chemical
agent.
General types:
– alkaline to pH neutral products,
– acidic to pH neutral products,
– hydrogen peroxide.
– Observe the chemical agent
manufacturer's instructions and
recommendations.
– Carry out a regular visual check of
the dispensing system for any
damage.
– Regularly check the flow rate of the
dispensing system.
Chemical agents can damage
elastomers and plastics in the
washer-disinfector and accessories.
– Observe the chemical agent
manufacturer's instructions and
recommendations.
– Carry out a regular visual check of
any accessible elastomers and
plastics for damage.
Hydrogen peroxide can release large
quantities of oxygen.
– Only use approved processes such
as OXIVARIO or OXIVARIO PLUS.
– The wash temperature must be less
than 70 °C when using hydrogen

Chemical agents
Problem How to resolve it
De-foaming agents, especially silicone
based ones can cause the following:
– deposits to build up in the cabinet,
– deposits to build up on the load,
– damage to elastomers and plastics
in the washer-disinfector,
– damage to certain plastics (e.g.
polycarbonate and plexiglass) in the
load being reprocessed.
– De-foaming agents should be used
in exceptional cases only, for
instance when absolutely essential
for the process.
– The wash cabinet and accessories
should be periodically cleaned
without a load and without
de-foaming agent using the
ORGANIC programme.
– Please contact Miele for advice.
Soiling
Problem How to resolve it
The following substances can damage
elastomers (hoses and seals) and
plastics in the washer-disinfector:
– oil, wax, aromatic and unsaturated

Reaction between chemical agents and soiling
Problem How to resolve it
Natural oils and fats can be emulsified
with alkaline chemical agents. This can
lead to a heavy build-up of foam.
– Where available use the "OIL"
programme.
– This special programme dispenses
cleaning agents containing tensides
(pH neutral) in the pre-rinse.
– Depending on application use
de-foaming agents that do not
contain silicone oils.
Soiling containing high protein levels
such as blood can cause a heavy
build-up of foam when processed with
alkaline chemical agents.
– Select a cleaning programme with at
least one short pre-rinse in cold
water.

in any mobile units or modules
– The wash cabinet and the door seal
– Mobile units, modules and inserts
Maintenance
65
Cleaning the filters in the wash
cabinet
The flat filter in the wash cabinet and
the circulation pump filters prevent
coarse soiling getting into the
circulation system.
The machine must not be used
without all the filters in place.
Watch out for glass splinters,
needles etc. on the flat filter in the
wash cabinet. Danger of injury.
Cleaning the flat filter
The flat filter can become clogged with
residual soiling. It must therefore be
cleaned at least once a day.
If heavy soiling is visible at the end of a
programme cycle the flat filter must be
cleaned before starting the next
programme.
Any visible residues remaining on the
flat filter after manual cleaning can be
removed by processing in the
washer-disinfector. The exact method
depends on the layout of the mobile

Intended Use
This washer-disinfector can be set up
or retro-fitted to use the OXIVARIO
process by adding two additional
dispenser pumps together with a buffer
tank for hydrogen peroxide solution
(H2O2). The DOS 2 dispenser is used
for the H2O2 solution.
To use the ORTHOVARIO process the
DOS 4 dispensing system has to be
replaced by a dispenser pump for a
tenside based cleaning agent.
The OXIVARIO, OXIVARIO PLUS and
ORTHOVARIO programmes are
available for these requirements.
The OXIVARIO process releases active
oxygen under alkaline conditions. The
cleaning agent used must be tenside
free and have a pH value of between
11 and 11.5.
The ORTHOVARIO process uses a
special tenside based cleaning agent
in the first cleaning phase and then
releases active oxygen in the second
phase with a pH value of between 10.0
and 11.0 and a slightly higher
temperature of 65 °C.
Areas of application
The OXIVARIO procedure has an
alkaline main wash making it
particularly suitable for the
reprocessing of surgical instruments
where existing procedures are not
satisfactory.
It is particularly suitable for instruments
such as those used in high frequency
surgery, orthopaedic surgery as well as
for instruments which have dried out
because of the length of time between
using them and reprocessing them.
It is also suitable for antiseptic
circumstances.
The OXIVARIO PLUS process is
designed to prevent transmission of
iatrogenic prions (vCJD).
The cleaning processes are gentle
enough for instruments used in
minimally invasive surgery, including
fibre optics, where the manufacturer
has declared that they are suitable for
reprocessing with an alkaline cleaning
agent.
They are not suitable for anodised
aluminium.
Be aware that items made from alloys
containing titanium such as some
implants, do not always state the
material's compatibility. Reprocessing
such items can result in colour
changes, rendering any coding on
them ineffective. If in doubt please
consult the manufacturer of the item.
Special processes - OXIVARIO and ORTHOVARIO
77
The ORTHOVARIO procedure is
suitable for reprocessing aluminium
instruments which are sensitive to
alkalines. It is particularly suitable for
orthopaedic instruments including
motor systems.
Because of its oxidising effect it
must not be used for titanium
implants, and in particular colour
coded ones.
Due to the high efficacy of the
Oxivario and Orthovario processes,
it is important to lubricate joints and
contact parts on instruments
pre-sterilisation. Please refer to the
instrument manufacturer for
guidance.
Warning and Safety
instructions
These warning and safety
instructions are in addition to those

Connecting the H2O
2solution
container
The connection hose for the H2O2
solution container is identified by a
black label. The connection hose is
supplied without a safety cap as the
container for hydrogen peroxide will
vary depending on supplier.
� Connect the supplier's safety cap to
the connection hose (black).
� Then connect this to the H2O2
solution container.
� Then start the DOS2-FILL
programme.
Unlike with other chemical agents the
H2O2 solution container must be fully
emptied before it is exchanged for a
new one.
� Do not replace the H2O2 solution
container with a new one until the Fill
DOS2 container message is
displayed. After connecting the new
container, you must run the
DOS2-FILL programme.
� If the Check dispensing system 2
message appears you should check
the container as well as the
dispensing system. The programme
will stop automatically.

Description
Washer-disinfectors fitted with a steam
condenser with heat recovery
(DK+WRG) are identified by the
following symbol.
DK+WRG variant machines can only be
used with a built-in boiler.
On these machines the steam
condenser is connected to an AD water
supply instead of to cold water. The AD
water used as a coolant flows through
the steam condenser into the boiler in
the washer-disinfector.
This pre-warming process reduces the
amount of energy required to heat up
water in the boiler. It also uses less
water than a steam condenser
connected to a fresh water system.
Because the water paths used in the
washer-disinfector are different the
water intake durations are longer in
those blocks that use hot AD water.
Areas of application
Washer-disinfectors with DK+WRG
must only be used for medical
applications.
To benefit fully from the heat recovery
system the washer-disinfector should
be operated without long pauses.
If the machine has not been
used for a longer period of time, e.g.
over a weekend the FILL BOILER
service programme must be run
before using the machine again.
For reasons of hygiene, this
programme replaces AD water from
the steam condenser and the boiler
with fresh cold AD water.
Special version with DK + WRG

Warning and Safety instructions
These Warning and Safety instructions are in addition
to those given at the beginning of this instruction manual.
� This washer-disinfector with DK+WRG must not be used
for reprocessing opthalmic instruments.
� With the Heat recovery system the boiler temperature of
90 °C must not be reduced. To prevent heat shock, thermally
sensitive items, e.g. fibre optic instruments should be
reprocessed using a procedure that is suitable for thermally
sensitive items. For example the last rinse before thermal
disinfection could be carried out with hot water.
� Particularly sensitive items should be checked for
suitability before reprocessing them in a programme that has
fluctuating temperature ranges.
Observe the manufacturer's instructions.
