Warning and safety instructions
This machine meets all statutory
safety requirements. Improper use
may cause accidents and damage
to the machine.
Before installation and before using
the machine for the first time, read
the operating instructions carefully.
This way you will avoid the risk of
accidents and damage to the appliance.
Keep the operating instructions in a
safe place.
Specified use of the machine
This thermal disinfector is only
authorised for the applications
mentioned in the operating instructions.
Do not use for purposes other than
those for which it was designed, as this
might be dangerous.
The manufacturer cannot be held responsible for damage caused by improper use of the machine.
Please note the following in order to
prevent accidents
Commissioning and repairs should
only be carried out by suitably
qualified and competent Miele service
technicians. Repairs by unqualified persons could be dangerous.
Do not install the machine where
there is the risk of explosion.
The electrical safety of this ma-
chine can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system. It is imperative that this basic
safety requirement is tested and, where
there is any doubt, the electrical system should be checked by a qualified
electrician.
The manufacturer cannot be held responsible for damage caused by the
lack or inadequacy of an effective
earthing system (e.g. electric shock).
A damaged machine poses a
safety risk. Disconnect the machine immediately from the mains supply and inform a suitably qualified service technician.
Repair work may only be carried
out by an authorised, suitably competent person. Repairs by unqualified
persons could be dangerous.
Personnel operating the machine
should be trained regularly. Children and untrained personnel should not
be allowed access to the machine or
its controls.

cleaning agents/additives. These
may contain irritants or corrosive substances. Do not use organic solvents
as there may be the danger of explosion.
Carefully follow the relevant safety instructions on packaging and wear protective gloves and goggles.
5
Warning and safety instructions
Avoid inhaling powder dust.
The water in the machine must not
be used as drinking water!
Do not sit or lean on the open
door. This could cause the ma-
chine to tip and be damaged.
Be careful when sorting sharp
pointed instruments not to injure
yourself. If necessary, place the
pointed end downwards with the
handles pointing upwards.
When using the machine at high
temperatures of 70–95°C take care
as the load is extremely hot and may
cause burns. Baskets and inserts must
first be allowed to cool. Empty any
water still remaining in concave items
into the cabinet before removing the
load.
Do not touch the heating elements
after the end of a programme as
this may cause burns.
Never use a hose or a high-press-
ure cleaner on or in the vicinity of
the machine.
Before carrying out repairs, discon-
nect the machine from the mains
supply (switch off at the main socket
and pull out the plug, switch off the
appropriate circuit at the fuse-box or
withdraw the mains fuse).
Please heed the following instructions in order to guarantee the
quality of cleaning performance and
to avoid damage.
The operator is responsible for
monitoring and guaranteeing the
standard of disinfection in the routine
disinfection process. Disinfection parameters should be checked regularly
using chemical indicators and contamination levels checked and documented
periodically using bioindicators.
The thermal disinfection pro-
gramme (DESIN 93°C-3’) – with a
3-minute holding time – is only suitable
as a prophylactic measure to combat
infection if the requirements of each
individual application are closely observed.
Disinfection programmes must not
be interrupted, as this may impair
the disinfection results. Should interruption be unavoidable, the whole programme must be repeated.
Only use detergents which have
been tested and recommended by
Miele for use in cleaner/disinfectors.
Use of other cleaning agents may
cause damage to both the load and the
machine.
Prior treatment (e.g. with detergent
or disinfectant), but also certain
types of soil and some detergents may
cause foaming which may have an adverse effect on the quality of cleaning
and disinfection.
6
Warning and safety instructions
The recommendation of specific
chemical products (e.g. detergent)
for individual applications does not
mean that the appliance manufacturer
accepts responsibility for any effect
these may have on the articles being
processed.
Please note that variations in formulation, storage conditions, etc. which are
not always announced by the detergent manufacturer, may affect the
quality of the cleaning results.
Only use water and cleaning
agents in a thermal disinfector. Do
not use organic solvents as there may
be a danger of explosion (Note: There
are many organic solvents which do
not pose a risk of explosion, but may
cause other problems, such as damage to elastomers and plastic components).
In the case of critical applications
requiring a particularly high standard of cleaning and disinfection, cleaning programmes and parameters
(detergent, quality of water, etc.)
should be coordinated with the Miele
Application Technology Department.
If a particularly high standard of
cleaning and rinsing is required
(e. g. chemical analysis, special industrial production, etc.), regular quality
checks must take place to guarantee
the correct standard of cleaning.
Use special inserts in accordance
with the instructions provided.
Empty all concave items before
placing them in the machine.
Do not allow any acid or solvent
residue, especially hydrochloric
acid and solutions containing chloride
to get into the wash cabinet. This also
applies to ferrous components susceptible to corrosion.
Solvent introduced with the soil should
only be present in traces. This is particularly the case in high-risk areas.
Take care that solutions/vapours
containing hydrochloric acid do
not come into contact with the stainlesssteel casing, as this may cause corrosion.
Please heed installation instruc-
tions and refer to the installation
diagram supplied with the machine.
Accessories
Use special inserts in accordance
with the instructions provided.
The only accessories to be used
with the special commercial machine must be those supplied or approved by MIELE for the specific application. Consult your dealer or the Miele
Professional department for advice.

Warning and safety instructions
Disposal of an old machine
When disposing of an old machine
first make it unusable. Disconnect,
cut off the cable and any plug from the
cable. For environmental and safety
reasons ensure the machine is completely drained of any residue water
and cleaning agent. (Observe safety
regulations and wear safety goggles
and gloves). Make the door lock inoperative, so that children cannot accidentally shut themselves in. The simplest
way to do this is to remove the locking
pin (2 philips screws above the door).
Make appropriate arrangements for the
safe disposal of the machine. For tank
system machines ensure that any water
is emptied out of the tank.
In countries where there are areas
which may be subject to infestation by cockroaches or other vermin,
pay particular attention to keeping the
machine and its surroundings in a
clean condition at all times. Any damage which may be caused by cockroaches or other vermin will not be
covered by the machine guarantee.
The manufacturer cannot be held responsible for any damage caused
through non-observance of these
Warning and Safety instructions.

cycle (set ex works).
The cleaner/disinfector can be used for
a variety of medical applications.
Baskets and inserts should be selected
to suit individual requirements.
Description of the machine
The cleaner/disinfector is
a water softener as standard.
A water softener is required in areas
with a water supply hardness of more
than 6 °d (1.07 mmol/l).

To avoid the build up of calcareous deposits on both the load and the machine, the water needs to be softened if
supply hardness is over 6°d
(1.07 mmol/l).
To ensure a steady supply of soft
water, the built-in water softener must
always be:
1. Correctly set
2. Topped up with salt as soon as the
k indicator light goes on.
When commissioning a machine, the
water softener must be set to correspond with the water supply hardness.
Your local water authority will advise
you on the water supply hardness in
your area.
Setting the water softener
The hardness range is divided into 18
increments and a zero position. The
thermal disinfector is set at the factory
for a water hardness time setting "8",
corresponding to 19°d (3.38 mmol/l).
If your water supply is harder or softer
than this, then:
Change the setting at the controls
(see table).

Application technology
Loading the machine
Prior to loading
Empty all items before placing them
in the machine (if applicable, observe regulations on preventing the
spread of contagious diseases).
Application technology
Loading the top basket
Insert small, lightweight and delicate
items and heat-resistant plastic.
Loading the bottom basket
Insert large, heavy items.
Do not allow any acid or solvent
residue, especially hydrochloric
acid and solutions containing
chloride to get into the wash
cabinet.
Notes
Load utensils so that water can access all surfaces. This ensures that
items will be thoroughly cleaned.
Do not place items inside each other
where they may be concealed.
Hollow items must be inverted.
Deep-based items should be placed
at an angle to enable water to run off
freely.
Tall hollow items should be placed in
the centre of the basket to allow
water easier access.
Mobile units or baskets with a watercircuit adapter must connect
properly.
Cutlery
Unsorted cutlery should be placed in
a cutlery basket, handles pointing
downwards.
Important note:
When a basket or mobile injector unit
with a spring-loaded water-circuit
adapter is used, it must connect
properly when inserted in the thermal
disinfector, i.e. it must be set 4-5 mm
higher so that it is forced downwards
by the connection in the roof of the machine.
If this is not the case, adjust the adapter as follows:
Loosen the clamping ring.
Push the adapter up (4-5 mm higher
than the water connection in the machine) and then tighten the clamping
ring again.
The rotation of the spray arms must
not be obstructed by items which
are too high for the basket or which
hang down in their path. If necessary, manually rotate the arms to test.
