cause liquids to leak out of it.
 The water in the wash cabinet is NOT safe to drink!
 Do not lift the machine by protruding parts such as the control
panel or the opened service flap as these could be damaged or torn
off.
 Do not sit or lean on the opened door. This could cause the
machine to tip and get damaged or cause injury.
 Use caution when sorting items with sharp pointed ends and
positioning them in the machine.
 Broken glass can result in serious injury during loading or
unloading. Broken glass items must not be processed in the machine.

IMPORTANT SAFETY INSTRUCTIONS
10
 When operating the washer-disinfector, bear in mind the possibility
of high temperatures. If the door is opened while bypassing the safety
lock, there is a danger of burning, scalding and chemical burns.
 Should personnel accidentally come into contact with toxic vapors
or process chemicals, follow the emergency instructions given in the
manufacturer's safety data sheets.
 Mobile units, baskets, 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.
 Never clean the machine with a water hose or a pressure washer.
 The machine must be disconnected from the electrical supply
before any maintenance or repair work is carried out.
Quality assurance
The following points should be observed to assist in maintaining
quality standards when processing medical instruments and
devices, in order to protect patients, and to avoid damage to the
loads being cleaned.
 If it is necessary to interrupt a program, as an exception only, this
may only be done by authorized personnel.
 The standard of cleaning and disinfection in the disinfection
programs must be routinely confirmed by the user.
 For intermediate-level thermal disinfection, use temperatures and
temperature holding times to achieve the required infection
prophylaxis in accordance with health and safety regulations.
 Make sure items being washed are suitable for machine
reprocessing and are in good condition. Plastic items must be
thermally stable. Nickel plated items and aluminum items can be
machine processed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.
 Process chemicals can, in certain circumstances, cause damage to
the machine. Always follow the recommendations of the process
chemical manufacturer.
In case of damage or doubt about compatibility, please contact
Miele.
 Instrument care products based on paraffin oils (white oils) can
damage the elastomers and plastics of the washer-disinfector. Such
care products may not be dispensed as chemical agents in these
washer-disinfectors even if they are recommended for machine use
by the instrument care product manufacturer.

IMPORTANT SAFETY INSTRUCTIONS
11
 Abrasive substances must not be placed in the machine as they
could cause damage to the mechanical components of the water
supply. Any residues of abrasive substances on items to be washed
must be removed without trace before reprocessing in the machine.
 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 cleaning and disinfection result.
 Processes must be set up such that foam cannot escape from the
wash cabinet. It would hinder the correct functioning of the machine.
 The process used must be monitored on a regular basis by the
supervisor to check foaming levels.
 To avoid the risk of damage to the machine and its accessories
caused by process chemicals, soiling and any reaction between the
two, please read the notes in "Chemical Processes and Technology."
 Even when a process chemical is recommended on technical
application grounds, it 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 publicized by the chemical manufacturer, can have
a negative effect on the cleaning result.
 When using a process chemical it is essential that the
manufacturer's instructions are followed. The process chemical 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).
 Always follow the manufacturer's instructions on storage and
disposal of process chemicals.
 Particles ≥1/16" (0.8mm) are removed by the filters in the wash
chamber. Smaller particles may find their way into the circulation
system. For this reason, processing of wash loads with narrow
openings requires additional filtering of the wash water.
 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 process chemicals, water quality, etc., are
discussed with Miele.
 The mobile units, baskets, modules and inserts that hold the wash
load must be used only as intended.
Hollow items must be thoroughly cleaned, internally and externally.
 Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
 Empty any containers or utensils before loading them.

IMPORTANT SAFETY INSTRUCTIONS
12
 The amount of residual solvents and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 70°F (21°C).
 Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 Ensure that solutions or steam containing chlorides or hydrochloric
acid do not come into contact with the stainless steel outer casing of
the machine in order to avoid any damage through corrosion.
 After any plumbing work, the water pipework to the machine will
need to be primed. If this is not done, components can be damaged.
 The gaps between a built-in machine and adjacent cabinetry must
not be filled with silicone sealant as this could compromise the
ventilation to the circulation pump.
 Follow the installation instructions in the operating and installation
instructions.

IMPORTANT SAFETY INSTRUCTIONS
13

Intended use of the machine
14
Proper use
Together with the use of the proper accessories and baskets, the
Miele washer-disinfector provides an automated process for the
cleaning and thermal, intermediate-level disinfection of re-usable
dental instruments prior to sterlization.
Fields of application
The Miele washer-disinfector has been designed for installation and
operation in the following fields of application:
– dental offices
– clinics for dental applications
– oral and maxillofacial surgery
Incorrect use
Do not use the Miele washer-disinfector as a machine for
reprocessing
– instruments for single use only
– hand pieces and dental turbines

General information for proper use
15
When processing instruments in the Miele washer-disinfector you
shall
– follow the instrument manufacturer's instructions for cleaning and
disinfection. Instruments must be disassembled according to the
manufacturer's instructions.
– follow Miele instructions for proper loading (included with specific
accessories of the machine and in the section "Applications" of this
manual) and instructions of the manufacturer of the instruments.
Proper instrument loading and connection of lumened instruments
to injection ports is required.
Any instruments that contact blood or compromised tissues shall
be sterilized prior to reuse following best practices such as AAMI
ST79.
Processing instruments in the machine facilitates repeatable results
with less opportunity for human error compared to manual cleaning.
Thermal disinfection can be carried out using the Vario TD programs
which meet the parameters to achieve intermediate-level, thermal
disinfection.
The cleaning program as well as chemical agents must be chosen
according to the type of soiling and load being processed. The final
result will be instruments that are clean, intermediate-level, thermally
disinfected, free of residue, and ready for subsequent sterilization.
Only then can the instruments be safely used.
Dental instruments are best processed using the Vario TD Dental
program. The use of a suitable load carriers (basket, module, insert
etc.) is important to ensure the adequate cleaning of the load.
Examples are given in the section "Applications". The washer-
disinfector can be programmed to perform the final rinse with tap
water (for utensils like trays), or with purified water of a quality to suit
the application (de-ionized, de-mineralized, reverse osmosis (RO),
distilled).
All instruments cleaned and thermally intermediate-level disinfected in
the washer-disinfector (with the exception of non-critical items, in
accordance to the Guideline for Disinfection and Sterilization in
Healthcare Facilities, 2008 of the Centers for Disease Control and
Prevention, USA) must be sterilized before use.
