Definition of terms
Cleaning machine In these operating instructions, the washer-disinfector is referred to
as “the cleaning machine”.
Load items The term “load items” is used wherever the items to be processed are
not defined in any further detail.
Wash water The term “wash water” is used for the mixture of water and process
chemicals.

Intended use
8
This Miele washer-disinfector is a Class IIb medical device (Directive
93/42/EEC).
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,
transmission instruments etc. can be reprocessed in this washer-
disinfector.
UK only: This washer-disinfector is NOT intended for reprocessing
transmission instruments such as turbines, hand-pieces and
contra-angles.
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 programme, e.g. the Vario TD programme should
be selected.
According to the A0 concept described in EN ISO 15883-1, 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.
Regional and/or other official directives may apply (CFPP, HTM or
relevant technical memorandums in the UK). Refer to your country's
local and national health and safety regulations and guidelines.
The cleaning programme must be chosen according to the type of
soiling and load being processed.
The agents 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 sterilisation can be carried out and that the
items can be used again safely.
Medical devices are best processed using the Vario TD programme
where applicable.
The use of a suitable carrier (mobile unit, module, insert, etc.) is
important to ensure the adequate cleaning of the load. Examples are
given in the section “Areas of application”.
This machine 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, fully demineralised water or demineralised water).
This machine complies with EN ISO 15883 for validation purposes.
This device is designed to wash and disinfect surgical instruments
before endpoint sterilisation.
