Intended use
8
This Miele washer-disinfector is a Class II medical device in
accordance with Health Canada.
This Miele washer-disinfector can be used to clean, rinse, and
thermally disinfect a wide range of reprocessable medical devices for
dental use. Information issued by the manufacturers of medical
devices (ENISO17664) must be heeded.
Instruments such as dental instruments, suction instruments,
handpieces etc. can be reprocessed in this washer-disinfector.
Reprocessing items 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 program, e.g. the Vario TD program should be
selected.
According to the A0 concept described in EN ISO 15883-1 (CAN/
CSA-Z15883), thermal disinfection occurs at 90°C (+ 5 °C, - 0 °C)
with 5 min holding time (A0 3000), depending on the disinfection
result required. The efficacy standard A0 3000 is suitable for
deactivating the HBV virus (Hepatitis virus).
Regional and/or other official directives may apply (e.g. CSA Z314.8
Decontamination of reusable Medical Devices in Canada). Refer to
your country's local and national health and safety regulations and
guidelines.
The cleaning program must be chosen according to the type of
soiling and load being processed. The processing chemicals used for
reprocessing the products should be selected to suit the level of
cleaning required.
The cleaning result must ensure that items can be disinfected
correctly, that subsequent sterilization can be carried out and that the
items can be used again safely.
Reusable medical devices are best processed using the Vario TD
program where applicable.
The use of a suitable carrier (basket, module, insert, etc.) is important
to ensure the adequate cleaning of the load. Examples are given in
the section “Areas of application”.
This 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. purified water, reverse osmosis water or
demineralized water).
This washer-disinfector complies with EN ISO 15883 (CAN/CSA-
Z15883).

 Never clean the machine or surrounding area with a water hose or
a pressure washer.
 The machine must be disconnected from the mains electricity
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 reprocessing medical devices, in order to
protect patients, and to avoid damage to property.
 If it is necessary to interrupt a program in exceptional
circumstances, this may only be done by authorised personnel.
 The standard of cleaning and disinfection in the disinfection
programs must be routinely confirmed by the user. The process
should be regularly tested and documented, both thermo-electrically
and through inspection.
 For thermal disinfection, use temperatures and holding times to
achieve the required infection prophylaxis in accordance with current
health and safety regulations.
 Make sure items being washed are suitable for machine
processing and are in good condition. Plastic items must be thermally
stable. Nickel plated items and anodised 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.
 Under certain circumstances, process chemicals can cause
damage to the machine. Users are urged to follow the
recommendations issued by manufacturers of process chemicals.
Contact Miele Service in the event of damage and any suspicion of
material incompatibility.
 Instrument care products based on paraffin oils (white oils) can
damage elastomers and plastics in the machine. Such care products
may not be dispensed as chemical agents in these machines even if
they are recommended for machine use by the care product
manufacturer.

Warning and Safety Instructions
16
 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-treating (e.g. with cleaning agents or disinfectants), some
types of soiling and the interaction of certain processing chemicals
can cause foaming. Foam can have an adverse effect on the cleaning
and disinfection results obtained.
 The process must be set so that no foam escapes the wash
compartment. Escaping foam jeopardizes the safe operation of the
machine.
 The process must be checked regularly in order to detect any
foaming.
 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 chemical additive (e.g. cleaning chemical) is
recommended on technical application grounds, the machine
manufacturer takes no responsibility for the effect of such chemicals
on the material of the items being cleaned.
Note that formulation changes, storage conditions, etc., that are not
disclosed by the chemical manufacturer may adversely affect the
cleaning results obtained.
 When using process chemicals, always consult the instructions
issued by individual manufacturers. Process chemicals must only be
used for the purpose for which they are designed by the
manufacturer to avoid any material damage or the occurrence of very
strong chemical reactions.
 Always follow the relevant manufacturer's instructions on storage
and disposal of process chemicals.
 Particles ≥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 (detergent, water quality, etc.) are discussed with Miele.
 The carts, 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.

Warning and Safety Instructions
17
 Empty all containers and hollow utensils before loading them into
the machine.
 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 21°C (70°F).
 Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 To avoid corrosive damage, make sure the stainless steel housing
does not come into contact with solutions or steam containing
hydrochloric acid.
 After any plumbing work the water pipework to the machine will
need to be vented. 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 of the circulation pump.
 Follow the installation instructions in the operating instructions and
in the installation instructions.

Warning and Safety Instructions
18
