Miele G 7825 Manual

							Loading the machine
–Arrange the load so that water can
access all surfaces. This ensures
that it gets properly cleaned.
–Do not place items to be cleaned
inside other pieces where they may
be concealed.
–Hollow instruments must be
thoroughly cleaned, internally and
externally.
–Ensure that instruments with long
narrow hollow sections can be
flushed through properly before
placing them in inserts or connecting
them to jets.
– Hollow vessels should be inverted
and placed in the correct mobile
units, modules and inserts to ensure
that water can flow in and out of
them unrestricted.
A cover can be used to reduce the
risk of glass breakage during the
wash process.
–
Lightweight items should be secured
with a cover net (e.g. an A 6) and
small items placed in a mesh tray to
prevent them blocking the spray
arms or being attracted by the
magnetic strip on the automatic
mobile unit recognition system.
–
Deep-sided items should be placed
at an angle to make sure water runs
off them freely.
–
Tall, narrow pieces should be placed
in the centre of the baskets. This
ensures good water coverage.–Mobile units with an adapter must
engage correctly.
–Modules must be correctly
connected in the mobile unit.
–The spray arms must not be blocked
by items which are too tall or which
hang down in their path. If in doubt,
test for free movement by manually
rotating the spray arms.
–It is advisable to use only instruments
made of special application steel
which are not susceptible to
corrosion.
– Instruments which cannot withstand
high temperatures should be
chemically disinfected.
Disposable instruments must not
be put into the machine for
processing.
Preparing the load
Empty all containers before loading into
the machine (paying particular attention
to regulations regarding infectious
diseases and epidemics).
Ensure that acids and residual
solvents, especially hydrochloric
acid or chlorides, cannot get into the
wash cabinet.
Unloading instruments
Instruments should be unloaded dry
ready for further processing.

							Surgical instruments (OP)
Surgical instruments should be stored
for as short a time as possible before
machine processing.
The OXIVARIO programme is
recommended for instruments where
there is a long delay between the time
they are used and the time they can be
reprocessed. See "Special features" at
the end of this booklet.
Disinfection of surgical instruments,
and of those used for minimal invasive
surgery should preferably take place
thermally.
De-ionised water should be used for
the final rinse whenever possible to
ensure no marks are left on the load
and to avoid corrosion. If the water
used contains more than 100 mg
chloride/litre there is danger of
corrosion.
OP-containerscan be disinfected
thermally in the CONTAINER
programme, or chemically. If anodised
aluminium containers are used the final
rinse must be carried out with
de-ionised water. These containers
must notbe processed with an alkaline
cleaning agent in a 93 °C programme
with 10 minutes holding time
(according to § 18 IfSG).
Mobile units for surgical instruments
and containers are supplied with
their own operating instructions.When cleaningnarrow lumen
instruments e.g. those used for
minimally invasive surgery,an
intensive internal cleaning result is
imperative. TheVario-TDand
OXIVARIOprogrammes are the only
ones which offer a thorough enough
level of cleaning for this. It is essential
that instruments are loaded as directed
and that the cleaning agent used is
suitable for the programme and for the
sensitive instruments being processed.
The final rinse must be carried out
using fully demineralised water with a
conductivity level of ~15S/cm
(microsiemens per centimeter).
Instruments with very narrow lumen
must be manually pre-rinsed where
necessary. Follow the instrument
manufacturer's instructions on how
to handle them.
Areas of application

							Ophthalmology
Opthalmic instruments should be
cleaned and disinfected in a special
mobile injector unit.
The top level is fitted with various
connections for hollow instruments, e.g.
rinsing and suction hand pieces, and
cannulae.
Instruments are secured to the hose
connectors in the mobile injector unit
using the silicone holders and
connectors in the rack.
The lower level of the mobile injector
unit is designed to take E 441/1 inserts
or E 142 mesh trays for processing
solid instruments.
Plastic fibre cover nets must not
be used in washer-disinfectors
which are used to process hollow
ophthalmic instruments with narrow
lumen.
The mobile injector unit for
ophthalmic instruments is supplied
with its own operating instructions.
Areas of application
23 
						

							Anaesthetic instruments (AN)
Anaesthetic instruments should be
thermally disinfected using the
DES-VAR-TD-AN programme.
If this is not possible, they can be
processed using a chemical
disinfection programme. The water
level in the machine should be
increased when using a chemical
disinfection programme. To establish
the effectiveness of disinfection, consult
the manufacturer of the disinfecting
agent being used.
If the process is not to be followed
by sterilisation, the load should be
dried completely to avoid the
development of water-borne
bacteria.
A sufficient drying time is, therefore,
absolutely essential.
Mobile units for anaesthetic
instruments are supplied with their
own operating instructions.
Areas of application
24 
						

							Baby bottles (BC)
Baby bottles can be processed in
E 135 containers in both bottom levels
of an E 735/1 mobile unit. An E 364
container with wide-necked teats or an
E 458 container with screw connection
teats can be processed at the same
time on the top level of the mobile unit.
–Ensure the level marker on the
bottles is machine-washable.
–If there is a delay of 4 hours or more
before bottles can be washed, fill
them with water to prevent residues
from drying on.
If the process is not to be followed
by sterilisation, the load should be
dried completely to avoid the
development of water-borne
bacteria.
A sufficient drying time is therefore
absolutely essential.
Inserts for baby bottles and teats are
supplied with their own operating
instructions.

							Frame E 750
Place the frame centrally in the top
level of the E 735/1 mobile unit.
Hook one E 135 container onto each
side of the frame.
The angled positioning of the
containers ensures that the jets of water
reach right into the bottles.
The two blocked corners in the
inserts should be located over the
positions marked with an X on the
drawing. The jets of water cannot
get into the bottles properly in these
positions to clean them.
Areas of application

							Operating theatre shoes (OS)
Polyurethane operating theatre shoes,
and/or insoles should be cleaned and
chemically disinfected at 60 °C. These
can only be thermally disinfected (using
programme SHOE-TD-75/2) if the
manufacturer states that they are made
of a suitably heat-resistant material.
To establish the effectiveness of
chemical disinfecting agents for
disinfection consult the manufacturer.
Theatre shoes should be cleaned
and disinfectedin a machine
installed specifically for this
purpose only.
Moble unit E 775-2 with a suitable insert
e. g. E 930, can be used for this
purpose.
A large amount of fluff can build up
in the machine when cleaning
theatre shoes. The filters in the wash
cabinet should therefore be
checked regularly, and cleaned
when necessary. See "Cleaning and
care".

							Laboratory glassware (LG)
Wide-necked laboratory glassware,
e. g. beakers, wide-necked Erlenmeyer
flasks and Petri dishes, and cylindrical
shaped items e. g. test tubes, can be
cleaned and rinsed, internally and
externally, by the action of the rotating
spray arms. They can be arranged in
full, half and quarter inserts in an empty
bottom or top basket with spray arms.
Narrow-necked items such as narrow-
necked Erlenmeyer flasks, conical
flasks, measuring flasks and pipettes,
require mobile injector units or injector
modules.
The following instructions relate only to
basic preparation and loading of
glassware.
Loading the machine
Removing excess soiling
Empty all glassware before loading
into the machine (paying particular
attention to regulations regarding
epidemics).
Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides, get into the wash
cabinet.

Remove all agar residues from Petri
dishes.

Remove blood clots and residues
from test tubes, etc.Remove all stoppers, corks, labels,
sealing wax residues, etc.
Small parts - such as stoppers and
taps - should be secured in suitable
basket inserts.
Please note
Petri dishes and similar should be
placed in the correct insert with the
soiled side facing the centre.
Pipettes should be placed with the
mouthpiece facing upwards.
Quarter inserts should be placed in
the mobile unit with at least 3 cm
between them and the edge of the
mobile unit.

							Transfer trolley for loading and
unloading the machine
When a disinfection process is
being carried out according to
nationally laid down hygiene
standards (e.g. § 18 IfSG), the
contaminated surfaces of the trolley
must be disinfected, after the
machine has been loaded, using a
spray disinfectant in accordance
with national health and safety
regulations and § 18 IfSG.
Disinfecting agents listed by DGHM
(German institute for microbiology
and hygiene) are also suitable.
The height of the transfer trolley can be
adjusted using the feet.
The height should be set so that the
open machine door is held underneath
the side catches on the transfer trolley.
If the machine is not fitted on a plinth
the position of the foot pedal on the
transfer trolley may need to be
changed.Unscrew foot pedal.
Loosen counter nuton adjusting
screw.
Screw adjusting screwfurther into
the foot pedal, so that the stopping
point is reached earlier.
Re-secure the adjusting screw.
Screw the foot pedal back on.
