Indications for use
High-level disinfection
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 tuberculosis and the
Enterococcus faecium.
IMPORTANT: Only the cycles labeled
‘DISINFECTION’ disinfect! Only use
these cycles when handling contaminated items. All other cycles are designed to clean items without disinfecting them!
The G 7782 Washer/Disinfector
achieves high-level disinfection as
defined by the Spaulding categoriza
tion.

WARNINGS AND SAFETY INSTRUCTIONS
WARNING - PERSONAL INJURY/
EQUIPMENT DAMAGE HAZARD:
Internal cleaning and disinfecting to a
measurable standard can only be
achieved with instruments that can be
dismantled and where the jets, sleeves
and adapters are used appropriately. A
special examination, over and above a
visual one, of the cleanliness of the in
ner area of the instruments should be
made. Minimally invasive surgical (MIS)
instruments should preferably be pro
cessed using the DISIN VARIO 93°C-10
MIN or DISIN 93°C-10 MIN program
with recommended detergents.
WARNING - BURN HAZARD: Allow
accessories to cool to room temperature before unloading. Any water
which may have collected in incorrectly
loaded items will be very hot and
should be emptied into the wash cabinet.
WARNING - BURN HAZARD:
Do not touch the heating elements
in wash cabinet after the end of a cycle.
-
-
WARNING - FALL HAZARD:
To prevent falls, keep floors dry by
immediately wiping up any spilled liq
uids in washer/disinfector loading and
unloading areas.
WARNING - ELECTRIC SHOCK
HAZARD: Washer/disinfector must
be correctly grounded!
WARNING - POTENTIAL
BIOHAZARD: Always use DISIN
FECTION cycles when processing
medical instruments and accessories.
Only DISINFECTION cycles provide
high levels of disinfection.
WARNING - PERSONAL INJURY/
EQUIPMENT DAMAGE HAZARD:
Do not fill container with cleaning detergent! Fill with reactivation salt only! Otherwise the pressurized container may
cause injuries by unscrewing.

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 in
structions provided.
CAUTION: If instruments have to
be dry for further instrument pro
cessing, the drying option of G 7782
may not be sufficient. In these cases
use G 7782 CD with a forced air drying
unit (TA).
CAUTION: The operator is respon-
sible for monitoring and guaranteeing the standard of disinfection in the
routine disinfection cycle. Disinfection
parameters should be checked regularly using chemical indicators, and
contamination levels checked and documented periodically using biological
indicators.

Installation
WARNING - EXPLOSION HAZARD:
Do not install the washer/disinfector
in area where flammable com
pounds/vapors are present.
IMPORTANT: The machine should only
be installed by a competent contractor.
The contractor should be experienced
in installing machines that require elec
trical hook-up as well as plumbing.
-
-
The machine can be installed in the fol
lowing ways:
Free-standing
^
^ Under counter.
The recess should be at least
3
23
/4" (60 cm) wide, 233/4" (60 cm)
deep, and 33
1
/4" (85 cm) high.
Washer/disinfector can be built into a
recess of 32
1
/4" (83 cm) high by remov-
ing the washer/disinfector top.
-
If necessary the washer/disinfector top
can be removed as follows:
^ Open the door.
^ Remove the screws on the left and
right, using a Philips screw driver.
^ Pull the top forward, lift and remove.
12
Installation
To re-assemble:
Replace plastic protective cap,
^
kickplate facing and service panel in
the reverse order which they were re
moved.
Make sure the grounding lead is
^
reconnected.
Do not use silicone sealant to seal
^
the gaps between the machine and
any neighboring units as this will hin
der ventilation to the circulation
pump.
-
-
The machine must be installed and leveled correctly. Any unevenness in the
floor can be compensated for by
screwing the adjustable feet in or out as
necessary. To level this unit, the service
panel and kickplate must first be removed.
To remove the service panel and
kickplate:
^
Take hold of the service panel at the
top of both sides and pull forward.
^
Remove all four kickplate screws.
^
Disconnect grounding lead if neces
sary.
^
Remove plastic protective cap.
-
Depending on the installation require
ments, the following kit is available:
Steam deflector
^ For use where the machine will be in-
stalled under a wooden countertop.
The underside of the work surface is
protected from steam damage by a
plate of stainless steel.

Electrical connection
IMPORTANT: All electrical work must
be carried out by a qualified electrician
and in compliance with all local and na
tional electrical codes.
Before making any connections, check
that the voltage shown on the data
plate corresponds to your power sup
ply. Data plate is located on back of
unit and behind service panel.
The washer/disinfector is supplied as
standard for connection to a 208 V,
60 Hz, single phase power supply and
is fitted with a power supply cord 6 ft
(1.8 m) long with a cross-section of
AWG 10-4. Connect washer/disinfector
to the main power supply (junction box
or electrical cord to outlet) according to
the opposite chart.
-
-
NOTE:
If an electrical cord is used,
make sure cord is the proper size and
voltage/current rating for the washer/
disinfector as identified on the data
plate.
Voltage: 208 V, single phase
Frequency: 60 Hz
Rated load: 6.0 kW
Circuit breaker: 30 A per phase
The washer/disinfector can be con
verted for connection to a 3-phase
power supply.
WARNING - ELECTRICAL SHOCK
HAZARD: Washer/disinfector must
be correctly grounded!

Connection to the cold water inlet
The machine must be connected to
^
the water supply in accordance with
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 "Programming special functions").
^ This machine is designed for cold
water connection only. Both inlet
hoses (water supply and steam condenser) must be connected to the
valves for cold water. Cold water sup
ply must be provided with shutoff
valves (by others).
^
Valves with
3
/4’’ male hose thread
should be provided near the washer
and should be easily accessible.
^
For additional protection of the valves
against impurities in the water supply,
large surface area filters are en
closed in the kit supplied with the
machine (see diagram in "Cleaning
and care, Maintaining the filter as
sembly").

Drainage
The drain system is equipped with a

non-return valve which prevents dirty
water from flowing back into the
washer/disinfector.
^ The machine is supplied with two
5 ft (1.5 m) long flexible drain hoses
with an inner diameter of
They should not be shortened or attached to any fittings that would
cause a reduction in water flow.
^ Longer drain hoses up to a length of
13 ft (3.3 m) are available if required.
-
^
Both hoses can be attached to exist
ing drain lines through the use of a
1
1
/2’’ (3.5 cm) or larger stand pipe /
P-trap combination. Alternately, the
hoses can be connected directly to
existing drain lines, provided any fit
tings or adapters used do not reduce
the water flow.
^
The drain hoses must not exceed
13 ft (3.3 m) in length, or be attached

to the main drain at a point higher
than 3 ft (1m) above the floor.
