This W&H washer-disinfector is a Class IIb medical device (Directive
93/42/EEC).
This W&H 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, trans-
mission instruments etc. can be reprocessed in this washer-disin-
fector.
UK only: This washer-disinfector is NOT intended for reprocessing
transmission instruments such as turbines, hand-pieces and con-
tra-angles.
The washer-disinfector is generally referred to as "the machine" in
these operating instructions. Reprocessable medical devices are re-
ferred to as "items" if they are not more closely defined.
Reprocessing items by machine achieves reproducible results and
should be used in preference to processing them by hand. Where dis-
infection 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 A

Regional and/or other official directives may apply (CFPP, HTM or rel-
evant 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 cor-
rectly, 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.
