							This washer disinfector is suitable for
cleaning and disinfecting instruments
and accessories in medical surgeries
and clinics, as well as gynaecology,
urology, ENT, anaesthetic and ortho
-
paedic instruments etc.
It is capable of cleaning and thermally
disinfecting instruments to general hy
-
giene requirements using the vario TD
(AN) programme and for standards re
-
quiring the containing of epidemics
(§ 18 IfSG) there is the SPECIAL (AN)
93°C/10’ programme as well as the
combiCHEM 60°C-5’ and CHEM
60°C-5’ programmes for thermal disin-
fection with the addition of a chemical
disinfecting agent.
The disinfection programme chosen will
depend on the area of effectiveness re-
quired  (bactericidal and/or virucidal)
and the thermal stabitily of the instru-
ments.
Where possible preference should be
given to thermal disinfection as this pro-
vides a better standard of disinfection.
The parameters for thermal disinfection
in accordance with EN ISO 15883-1 are
80 °C (+ 5 °C, - 0 °C) with a 10 min.
holding time or 90 °C (+ 5 °C, - 0 °C)
with a 5 min. holding time for the inacti-
vation of HBV.
Contaminated instruments can be
placed directly in the machine without
pre-treatment (no soaking required).In Germany, the parameters for disin
-
fection of a temperature of 93 °C, with a
holding time of 10 minutes, correspond
-
ing to effective areas A and B, have
been adopted into the official list for
disinfection of instruments in
disinfectors and decontamination units,
according to section 3.2.4. § 18 IfSG by
the Robert Koch Institute (RKI) in Berlin
(German Institute for infectious dis
-
eases and non-communicable ill
-
nesses).
The effective areas are defined as fol
-
lows:
A = suitable for the destruction of vege-
tative bacteria, including myco-bacte-
ria, fungus and fungal spores.
B = suitable for the inactivation of vi-
ruses (including HBV and HIV).
Chemo thermal disinfection takes place
at 60°C with a 5 minute holding time
and 1% concentration of disinfecting
agent. The standard of disinfection is in
accordance with the disinfecting agent
manufacturer’s instructions.
The machine is programmed to carry
out the final rinse with mains water or
AD water (aqua destillata) = purified or
de-ionised water (VE), H
2O pure, de-
mineralised water, aqua purificata or
distilled water where the application re-
quires this standard.
The washer-disinfector is equipped as
standard with a steam condenser (DK)
and water softener.

notes, to maintain safe procedures.
Do not install the machine in an
area where a danger of explosion
or of freezing conditions may be pres-
ent.
The electrical safety of this ma-
chine can only be guaranteed if
connected to a correctly installed
earthing system on site. It is most im-
portant that this basic safety require-
ment is met and complies with local
and national regulations. It should be
checked by an expert if necessary.
The manufacturer cannot be held liable
for the consequences of an inadequate
earthing system (e.g. electric shock).
A damaged machine is dangerous.
Switch off at the mains immediately
and call the Miele Service Department
or an authorised and trained Miele Ser-
vice Dealer.

							Personnel operating the machine
should be trained regularly.
Children and untrained personnel must
not be allowed access to the machine
or its controls.
Take care when handling liquid
agents and additives. These may
contain irritant or corrosive ingredients.
Do not use organic solvents as these
could cause an explosion.
Follow all relevant safety procedures
carefully. Wear protective gloves and
goggles. With all chemical agents the
manufacturer’s safety conditions must
be observed.
Avoid inhalation of powder
cleaners. They can cause burning
in the mouth and throat if swallowed, or
inhibit breathing.
The water in the machine must not
be used as drinking water.
Do not sit or lean on an open door.
The machine could tip up and be
damaged or cause an injury.
Be careful when sorting items with
sharp pointed ends and position-
ing them in the machine that you do not
hurt yourself or create danger for other
operators.
When using this machine in the
higher temperature ranges be es
-
pecially careful not to scald or burn
yourself when opening the door! Bas
-
kets, inserts and utensils must be al
-
lowed to cool down before they are un
-
loaded. Any water remaining in contain
-
ers could still be very hot. Empty them
into the wash cabinet before taking
them out.
Do not touch the heating elements
if you open the door during or di
-
rectly after the end of a programme,
you could burn yourself. They remain
hot for some time after the end of the
programme.
Never clean the machine or near
vicinity with a water hose  or a high
pressure hose.
Before any maintenance or repair
work is undertaken, the machine
must be disconnected from the mains
supply, by switching off at the mains
isolator, or withdrawing the mains fuse.
The following points should be ob-
served to assist in maintaining qual-
ity standards for special medical in-
struments, to protect patients, and to
avoid damage to the loads being
cleaned.
If the machine is being used for
disinfection in accordance with offi-
cial regulations on the control of epi-
demics, the steam condenser and its
connections to and from the wash cabi-
net must be cleaned and disinfected
whenever any repairs are carried out or
parts replaced.

							When running a disinfecting
programme in accordance with offi
-
cial regulations on the control of epidem
-
ics, the programme must not be inter
-
rupted once it has been started (see Can
-
celling a programme in an emergency).
The standard of disinfection in the
disinfection programmes must be
routinely confirmed by the user. The
process should be regularly monitored
using chemical indicators, and bacteri
-
ologically at intervals using bio-indica
-
tors, with full documentation.
Disinfection programmes must not
be interrupted, as this can have a
limiting effect on the disinfection result.
However, should this be necessary, the
complete programme must be re-
peated.
For thermal disinfection, use tem-
peratures and operating parameters
to achieve the required infection prophy-
laxis in accordance with current health
and safety regulations.
Thermal disinfection should be
used in preference to chemo-ther-
mal disinfection. Adequate cleaning re-
sults are essential in order to achieve
satisfactory disinfection results.
The CHEM and combiCHEM
programmes which need the addi-
tion of a chemical disinfection agent are
not recognised by IfSG and should only
be used if the items being cleaned and
disinfected cannot withstand high tem-
peratures. The range of effective disin-
fection is based on claims made by the
producer of the disinfecting agent.
Their instructions on handling, use and
effectiveness much be observed. Theuse of chemo thermal disinfection pro
-
cedures is the responsibility of the op
-
erator. The standard of disinfection
must be routinely checked.
Only use Miele approved cleaning
agents formulated for use in
washer disinfectors in this machine.
Using unsuitable cleaning agents could
adversely affect items being cleaned as
well as the components of the machine.
Pre-treatments with cleaning or dis
-
infecting agents can create foam,
as can certain types of soiling and rins
-
ing agents. Foam can have an adverse
effect on the disinfection and cleaning
process.
Where a chemical additive is rec-
ommended on technical applica-
tion grounds (e.g. a cleaning agent),
this does not imply that the manufac-
turer of the machine takes responsibility
for the effect of the chemical on the
items being cleaned.
Please be aware that changes in formu-
lation, storage conditions etc. which
may not be publicised by the chemical
manufacturer, can have a negative ef-
fect 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 ex-
clusion of other chemicals, to avoid
such dangers as chemical reactions
and material damage.
Warning and Safety instructions

							The machine is designed for oper
-
ation with water and additive clean
-
ing agents only. Organic solvents must
not be used in the machine, as there is
the danger under certain circum
-
stances of explosion. Although this is
not the case with all organic solvents,
other problems could arise with their
use, for example damage to rubber and
synthetic materials.
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 cleaning agent, quality of water
etc. are discussed with the Miele Appli-
cation Technology specialists.
The mobile units and special in-
serts should only be used for their
specific application. Hollow instruments
must be throughly cleaned, internally
and externally.
Empty any containers or utensils
before arranging them in the ma-
chine.
Do not allow any remains of acids
or solvents, and in particular hydro-
chloric acid or chloride solutions to get
into the wash cabinet. Similarly avoid
any materials with a corrosive effect.
The presence in compounds of any sol-
vents should be minimal, (especially
those in hazard class A1).
Ensure that solutions or steam con
-
taining hydrochloric acid do not
come into contact with the steel outer
casing of the machine, to avoid any
corrosion damage.
Please follow the advice on instal
-
lation in these instructions and the
separate Installation Instructions.
Using accessories
Only use genuine Miele accesso
-
ries with this machine. Consult
Miele on the type and application of
such equipment.
Disposal of your old machine
Before disposing of your old ma-
chine first make it unusable. Dis-
connect, cut off the cable and any plug
from the cable.
For environmental and safety reasons
ensure the machine is completely
drained of any residual water and
cleaning agent. (Observe safety regula-
tions and wear safety goggles and
gloves).
Make the door lock inoperative, so that
children cannot accidentally shut them-
selves in. Then make appropriate ar-
rangements for the safe disposal of the
machine.
The manufacturer cannot be held lia-
ble for damage caused by non-com-
pliance with these Warning and
Safety instructions.
