The G 7782 Washer/Disinfector is suit-
able for automatic treatment of medical
instruments and accessories. It cleans
and, when using the disinfection cycles
simultaneously, thermally disinfects at
200°F (93°C) instruments and accesso-
ries.
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 tubercu osis and the
Enterococcus faecium.
IMPORTANT: Only the cycles labeled
‘DISINFECTION’ disinfect! Only use
these cycles when handling contami-
nated items. All other cycles are de-
signed to clean items without disinfect-
ing them!

all local and national plumbing
codes.
^The machine is constructed with an
air gap/anti-siphoning device on both
the intake and the drain sides. No
such additional devices are neces-
sary or recommended, as they will
impede the water inflow into and out
of the washer.
^The water pressure must be between
35 and 145 psi (2.5 - 10.0 bar). If the
water pressure is not within this
range, the Miele Technical Service
Department can advise you of the
measures to be taken (see "Pro-
gramming special functions").
^This machine is designed for cold

To avoid the build-up of calcium depos-
its on items being cleaned and disin-
fected in the washer/disinfector, the
water may need to be softened (where
the supply hardness exceeds 107 ppm
CaCO3).
To ensure a steady supply of soft water,
the water softener must always be:
–correctly set
–regenerated with salt as soon as the
REACTIVATION indicator light comes
on.
The water softener should be set to cor-
respond with the water hardness upon
installation of the washer/ disinfector.
Your local water authority can advise
you on the water hardness in your area.
Setting the water softener
The hardness range is divided into 18
units and a zero position. The washer/
disinfector is set at the factory for a
water hardness setting of 8, corre-
sponding to 339 ppm CaCO3. If your
water supply is harder or softer than
this, change the setting as follows:
