This Miele washer-disinfector is designed to clean, rinse, disinfect
and dry re-usable medical devices, laboratory equipment and
accessories from these areas. Always comply with the manufacturer's
instructions for the particular medical devices (EN ISO 17664; CAN/
CSA-Z17664) as well as for the laboratory equipment.
Typical applications include:
– surgical instruments,
– minimally invasive instruments,
– instruments for anaesthetics and intensive care,
– baby bottles and teats,
– OR shoes
– rigid sterilization containers made of stainless steel and aluminum
(including colour anodized aluminum),
– laboratory equipment used in research and production
– laboratory equipment for analytical and preparation applications
– microbiology and biotechnology laboratory equipment
Laboratory equipment includes devices from beakers, bottles,
centrifuge tubes, Erlenmeyer flasks, funnels, pipettes, Petri dishes
and round bottom flasks.
Medical devices, laboratory glassware and laboratory utensils for
reprocessing are referred to as the wash load if they are not more
closely defined.
Reprocessing instruments or laboratory equipment by machine
achieves reproducible results and should be used in preference to
processing by hand. Where disinfection is required to protect staff
and/or patients, a thermal disinfection program, e. g. the DES-VAR-
TD program, should be selected.
According to the A0 concept described in EN ISO 15883-1 (CAN/
CSA-Z15883-1-09), thermal disinfection occurs at 80°C (+ 5 °C, - 0
°C) with 10 min holding time (A0 600), or 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 includes the inactivation of
the Hepatitis Virus.
Regional and/or other official directives may apply (e. g., CSA Z314.8
Decontamination of reusable Medical Devices).
The cleaning parameters should be optimally matched to the type of
soiling and load being processed.
The processing chemicals used for reprocessing the products should
be selected to suit the particular cleaning needs, and where
applicable, to the analysis / analytical methods involved.

Intended use
6
The cleaning result must ensure that the load can be disinfected
correctly, that no residues are left behind, that subsequent
sterilization can be carried out and that the instruments can be used
again safely.
Re-usable medical devices are best reprocessed using the DES-VAR-
TD process, or where applicable, the OXIVARIO process.
The use of a suitable carrier (wash carts, modules, insert, etc.) is
important to ensure the adequate cleaning of the load. Examples are
given in the section "Areas of application".
The washer-disinfector is designed to rinse with tap water or
processed water (e.g., distilled water, pure water, demineralized
water, partially demineralized water) depending on the quality
required for your application(s). The water quality selected is
especially important for laboratory equipment intended for analytical
uses.
This washer-disinfector complies with EN ISO 15883 (CAN/CSA-
Z15883).
User profiles
Daily-routine
operators
For daily-routine operation of the washer-disinfector, operators must
be instructed and receive regular training in the basic functions and
loading of the washer-disinfector. They require a basic knowledge of
machine reprocessing of medical devices.
Tasks for daily-routine work are located in operating levels A and C.
Daily-routine
supervisors
Advanced knowledge of the machine-based reprocessing of medical
devices is required for more complex tasks such as program
interruption or program cancellation.
These tasks take place on operating level B.
Service tasks and
administration
Additional expertise is required for changing the processes or
adjusting the washer-disinfector, e.g. to suit accessories that are
used or the site conditions.
This requires special expertise in the machine-based reprocessing of
medical devices, in the reprocessing technology and the applicable
standards and legislation.
Service tasks and alterations are carried out on operating level D.
