Description of the machine
The G 7883 CD washer-disinfector is a
front loading machine designed
specifically for processing laboratory
utensils and glassware.
In general these include glass, heat
tolerant plastic, stainless steel and
coated metal items such as containers
(e.g. beakers, narrow necked and
conical flasks, Erlenmeyer flasks,
bottles, test tubes, separatory funnels
etc.), measuring vessels (e.g.
volumetric flasks, measuring cylinders,
pipettes etc.), dishes (e.g. Petri dishes,
mortars, watch glasses etc.) and small
components (e.g. stoppers, spatula,
stirrers etc.).
The main aim of processing laboratory
utensils and glassware is to remove
contaminations from both external and
internal surfaces and to rinse off any
cleaning and neutralising agents.
The G 7883 CD is designed to process
one batch at a time. Items are loaded
into inserts and mobile units which are
then pushed into the wash cabinet. The
door is then closed and the programme
is started manually. At the end of the
programme the operator opens the
door, removes the mobile unit and
inserts and unloads the items.
The G 7883 CD is a single cabinet
system in which the whole process
takes place, including the pre-wash,
main wash, neutralisation, interim and
final rinses. Drying can be selected as
an additional function to complete the
process. Each programme stage
follows on automatically after the
previous one.
The main wash, neutralising and rinse
stages are all carried out using water
based agents only. In other words using
cold, hot or fully demineralised water
with the addition of a suitable chemical
agent (cleaning agent or neutralising
agent). Other liquid agents such as
organic solvents or combustible agents
must not be used in this machine.
Before processing anything in this
machine make sure that it is suitable for
machine processing and that it is for
example heat, acid and alkali tolerant.
It is the user’s responsibility to decide
whether items contaminated with
substances such as micro biological
material, pathogenic cells, facultative
pathogenic cells, genetically modified
material etc. should be sterilised before
machine processing.
4
Description of the machine
If sterilisation is not required prior to
machine preparation, the user must
also ascertain whether to use the "vario
TD" programme for cleaning and
disinfection to general hygiene
requirements, or whether to use the
"SPECIAL 93°C/10’" (§ 18 IfSG) for
cleaning and disinfection in
accordance with national Health and
Safety regulations regarding the
containing of epidemics. The
disinfecting programme chosen will
depend on the area of effectiveness
required (bactericidal and/or virucidal)
and on the thermal-stability of the
instruments. Contaminated items, not
requiring initial sterilisation, can be
placed directly in the machine without
pre-treatment (no soaking required).
The parameters for thermal disinfection
in accordance with prEN ISO 15883-1
are 80 °C (+ 5 °C, - 0 °C) with a 10 min.
holding time or 90 °C (+ 5 °C, - 0 °C)
with a 5 min. holding time for the
inactivation of HBV.
The effective areas are defined as
follows:
A = suitable for the destruction of
vegetative bacteria, including
myco-bacteria, fungus and fungal
spores.
B = suitable for the inactivation of
viruses (including HBV and HIV).

sharp pointed ends and
positioning them in the machine that
you do not hurt yourself or create a
danger for others. Sharp knives etc.
should be placed in baskets with the
pointed ends facing downwards.
When using this machine in the
higher temperature ranges, be
especially careful not to scald or burn
yourself or come into contact with
irritant substances when opening the
door! Where disinfecting agents are
used there is a danger of inhaling toxic
fumes. Baskets, inserts and utensils
must be allowed to cool down before
they are unloaded. Any water remaining
in containers could still be very hot.
Empty them into the wash cabinet
before taking them out.
Do not touch the heating elements
if you open the door during or
directly after the end of a programme;
you could burn yourself. They remain
hot for some time after the end of the
programme.
Never clean the machine or near
vicinity with a water hose or a high
pressure hose.
The machine must be
disconnected from the mains
electricity supply before any
maintenance or repair work is carried
out. Do not reconnect it until the

Warning and Safety instructions
The following points should be
observed to assist in maintaining
quality standards for processing
medical instruments and senstitive
laboratory glassware, and to avoid
injury to patients or damage to
equipment.
If the machine (depending on mo
del) is being used for disinfection
in accordance with official regulations
on the control of epidemics, the steam
condenser and its connections to and
from the wash cabinet must be cleaned
and disinfected whenever any repairs
are carried out or parts replaced.
For decontamination in
accordance with official
regulations, the programme must not
be interrupted by pressing the I-0
button to switch off after START has
been pressed . Interrupting any other
programmes should also be avoided as
this will reduce cleaning, disinfection
and the final rinse results. If it is opened
the programme should be completely
repeated.
The standard of cleaning and
disinfection in the disinfection
programmes must be routinely
confirmed by the user. The process
should be regularly monitored using
thermo-electrical, chemical or
bio-indicators, and this should be fully
documented.
-
For thermal disinfection, use
temperatures and temperature
holding times to achieve the required
infection prophylaxis in accordance
with current health and safety
regulations.
Only use chemical agents
formulated for special processes
and approved by Miele for use with this
machine. Use of unsuitable agents
could adversely affect the components
of the machine. Any resultant damage
would invalidate the machine
guarantee.
Pre-treatments with cleaning or
disinfecting agents can create
foam, as can certain types of soiling
and chemical agents. Foam can have
an adverse effect on the disinfection
and cleaning process.
Where a chemical additive is
recommended on technical
application grounds (e.g. a cleaning
agent), this does not imply that the
manufacturer of the machine takes
responsibility for the effect of the
chemical on the items being cleaned.
Please be aware that changes in
formulation, storage conditions etc,
which may not be publicised by the
chemical manufacturer, can have a
negative effect on the cleaning result.
10
Warning and Safety instructions
When using cleaning agents and
specialised products, it is essential
that the manufacturer's instructions are
followed. Chemicals must only be used
for the purpose they are designed for
and in the situation specifed, to the
exclusion of other chemicals, to avoid
such dangers as chemical reactions
and material damage.
The machine is designed for
operation with water and
recommended additive chemical
agents only. Organic solvents must not
be used in this machine, as there is the
danger under certain circumstances of
fire or explosion. Although this is not the
case with all organic solvents, other
problems could arise with their use, for
example damage to rubber and
synthetic materials.
In critical applications where very
stringent requirements have to be
met, it is strongly recommended that all
the relevant factors for the process,
such as cleaning agent, water quality
etc. are discussed with the Miele
Application Technology specialists.
The special inserts should only be
used for the purpose they are
designed for. Hollow instruments must
be throughly cleaned, internally and
externally.
Empty any containers or utensils
before arranging them in the
machine.
Do not allow any remains of acids
or solvents, and in particular
hydrochloric acid or chloride solutions,
to get into the wash cabinet. Similarly
avoid any materials with a corrosive
effect.
The presence in compounds of any
solvents should be minimal (especially
those in hazard class A1).
Ensure that solutions or steam
containing hydrochloric acid do not
come into contact with the steel outer
casing of the machine, to avoid any
corrosion damage.
Please follow the advice on
installation in these instructions
and the separate Installation
Instructions.
If cleaning and rinsing results are
subject to particularly stringent
requirements (e.g. chemical analysis,
specialised industrial processes etc.), a
regular quality control test must be
carried out by the user to ensure that
the required standards of cleanliness
are being achieved.
11
Warning and Safety instructions
Using accessories
Only use genuine Miele
accessories with this machine.
Consult Miele on the type and
application of such equipment.
Only use Miele mobile units,
baskets and inserts in this
machine. Using accessories made by
other manufacturers, or making
modifications to Miele accessories can
result in unsatisfactory cleaning and
disinfecting results, for which Miele
cannot be held liable. Any resultant
damage would also invalidate the
machine guarantee.
Disposal of your old machine
Before throwing an old machine
away, it must first be made
unusable. Disconnect it from the mains
and cut off the cable as close to the
machine as possible.
Please note that the machine may have
contamination from blood or other
bodily fluids in it and must be
decontaminated before disposal.
For environmental and safety reasons
ensure the machine is completely
drained of any residual water, chemical
residues and cleaning agent. Observe
safety regulations and wear safety
goggles and gloves.
Make the door lock inoperable, so that
children cannot accidentally shut
themselves in. Then make appropriate
arrangements for the safe disposal of
the machine.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.
12
Caring for the environment
Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and can normally be recycled.
Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation.
Rather than just throwing these
materials away, please ensure that they
are recycled.
Disposal of your old appliance
Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.
Please do not therefore dispose of it
with your household waste.
Please dispose of it at your local
community waste collection / recycling
centre and ensure that it presents no
danger to children while being stored
for disposal.
It should be unplugged or disconnected
from the mains electricity supply by a
competent person. Any plug must be
rendered useless and the cable cut off
directly behind it to prevent misuse.

Water softener
The water needs to be softened to
avoid calcium deposits building up on
instruments and utensils and in the
machine itself.
To ensure a steady supply of soft water
the water softener unit must always be:
1. correctly set (programmed) and
2. the salt reservoir must be filled.
(If the water hardness level is below
0.7 mmol/l (4 °d - German scale) the
reservoir does not need to be filled
with reactivation salt.)
The machine is set at the factory for a
water hardness level of 3.4 mmol/l
(19 °d).
If the water supply is harder or softer
than this (including below 0.7 mmol/l
or 4 °d) the factory setting will need
to be changed following the
instructions in "Setting the water
softener". See chart on the next
page for settings.
Your local water authority will advise
you on the water hardness in your area.
For fluctuating levels (e.g. 1.4 - 3.1
mmol/l or 8 - 17 °d) set the water
softener to the highest setting (in this
example to 3.1 mmol/l or 17 °d).

Rinsing agent
If rinsing agent is required the
rinsing agent reservoir in the
machine will first need to be
activated by a Miele Service
technician.
Rinsing agent helps water run off items
so that no droplets are left behind and
improves drying results. However,
because rinsing agent is dispensed
during the final rinse some of its
ingredients will remain on the surfaces
of your laboratory glassware etc. It
should therefore only be used if it does
not have an adverse effect on the
application the glassware or utensils
are being used for.
If used, it is poured into the rinsing
agent reservoir in the door and the
amount set is then automatically
dispensed during the final rinse.
The rinsing agent reservoir holds
approx. 180 ml.

There is also a level indicator for the
