If thermal disinfection is required
(93 °C / 10 min.), the process
needs to be checked and documented
regularly. This can be done by check-
ing the disinfection control diode on the
machine. Alternatively, a chemical indi-
cator may be used (e.g. the Disinfec-
tion Control Tubes by A. Browen Ltd.,
supplied by Miele). These disinfection
control tubes should be placed in the
filter combination. After the disinfection
cycle, they may be inspected by re-
moving the coarse filter.
CAUTION: Washer/disinfector must
not be used without all filters in
place.
CAUTION: Use only accessories
specifically designed for this
equipment. Load accessories into
washer/disinfector in accordance with
the instructions provided.
CAUTION: The operator is respon-
sible for monitoring and guarantee-
ing the standard of disinfection in the
routine disinfection cycle. Disinfection
parameters should be checked regu-
larly using chemical indicators, and
contamination levels checked and doc-
umented periodically using biological
indicators.

The G 7782 CD Washer/Disinfector is
intended for cleaning and disinfection
of dental and general medical instru-
ments and accessories. It cleans and,
when using the disinfection cycles, si-
multaneously thermally disinfects at
(93 °C) instruments and accessories.
Areas of effectiveness are physical re-
moval or thermal inactivation of vegeta-
tive bacteria including mycobacteria,
fungi, fungal spores, and viruses.
These categories include the Mycobac-
terium tuberculosis and the
Enterococcus faecium.
The intended use is identical for pro-
cessing medical and dental instrumen-
tation. Miele, Inc. considers general
medical instruments to be only insignifi-
cantly different from detal instruments.
Materials used are identical (mostly
stainless steel); architectures are sim-
ple and very similar.
Important: Only the cycles labeled
‘DISINFECTION’ disinfect! Always use
these cycles when handling contami-
nated items. All other cycles are de-
signed to clean items without disinfect-
ing them!
IMPORTANT: Centers for Disease Con-
trol Publication PB85-923404,
Guideline
for Handwashing and Hospital Environ-
mental Control, 1985,
defines the pro-
cessing requirements for critical,
semi-critical and non-critical instru-
ments. Refer to these definitions to de-
termine when and under what condi-
tions the G 7782 CD Washer/Disinfector
can be used.
