Miele G 7893 Manual

							The cleaning result must ensure that
the instruments have been disinfected
correctly, that no residues are left
behind, that subsequent sterilisation
can be carried out and that the
instruments can be used again safely.
Medical products are best reprocessed
using the DESIN vario TD programme.
The use of a suitable carrier (mobile
unit, module, insert etc.) is important to
ensure the adequate cleaning of
instruments and products. Examples
are given in the section "Areas of
application".
The washer-disinfector is programmed
to carry out the final rinse with mains
water or with processed water of a
quality to suit the application (e.g. aqua
destillata, purified water, de-ionised
water, demineralised water). The water
quality is of particular importance for
applications requiring analytically clean
laboratory glassware.
This machine complies with EN ISO
15883 for validation purposes.

							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 machine
Electrical and electronic
machines 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 machine. 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.

							Electric door lock
This machine is equipped with an
electric door lock.
The door can only be opened when:
^the electricity supply to the machine
is switched on and
^the On-Off switchI-0is pressed in.
To open the doora
^Press the door release switch in as
far as it will go, and at the same time
grip the handle and open the door.
,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.
The door cannot be opened after a
programme has been started, and it
remains locked until the end of the
programme. It is still possible to open
the door during the PRE-RINSEDand
DRAIN6programmes.
The machine can be programmed (by a
Miele approved service technician) to
open during "Drying".
To close the door
Lift the door upwards and push until it
clicks shut. Do not press the door
release button whilst shutting the door.
To open the door with the
emergency release
The emergency release should only
be used when the door cannot be
opened normally, e.g. in the event of
a power failure.
Important note for SPECIAL
programmes - read the notes in the
Warning and Safety instructions.
^Turn the programme selector tof.
^Switch the machine off with theI-0
switch.
^
The emergency release cord is
located at the bottom of the machine
behind the service panel. Pull it
downwards to open the door.

							In order to achieve good cleaning
results, the washer-disinfector needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on instruments etc. and in the
washer-disinfector.
Mains water with a hardness level
higher than 0.7 mmol/l (4° d – German
scale) needs to be softened. This takes
place automatically in the integrated
water softener.
–The water softener requires
reactivation salt.
–The washer-disinfector must be
programmed to correspond to the
water hardness in your area.
– Your local water authority will be able
to advise you on the water hardness
in your area.
Where the water hardness fluctuates
e.g. between 1.4 - 3.1 mmol/l (8 - 17 °d
German scale) always programme the
washer-disinfector to the higher value
(3.1 mmol/l in this example).
The built-in water softener has
settings from 1 °d - 60 °d (0.2 -
10.8 mmol/l).
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
Enter the water hardness below:

							Filling the salt reservoir
Only use special coarse grained
reactivation salt with granules of
approx.1-4mm.Donotuseother
types of salt such as cooking salt,
agricultural grade or gritting salt. These
may contain insoluble additives which
can impair the functioning of the water
softener. If in doubt consult the Miele
Professional Department.
The salt reservoir holds approx. 2.5
kg of salt.
,Inadvertently filling the salt
reservoir with cleaning agent will
damage the water softener.
Before filling the salt reservoir make
sure that you have picked up the
right packet of reactivation salt.
^Remove the bottom basket from the
machine.
^
Unscrew the salt reservoir cap.
Before filling the salt reservoir with
reactivation salt for the first time, you
must fill it with approx. 2.5 litres of
water to enable the salt to dissolve.
Once the washer-disinfector has
been used, there is always sufficient
water in the reservoir.^Place the funnel provided in position.
^Fill carefully with salt.
As it is poured in, displaced water will
run out.
^Remove the funnel and wipe any
residual salt off the screw threads on
the socket.
^Screw the cap back on firmly.
^Run the PRE-RINSEDprogramme to
remove any traces of salt from the
cabinet.
The programme sequence may be
delayed for a few minutes after the
start of the PRE-RINSED
programme. This is not a fault. The
water softener is being reactivated.

happening.
^Add salt when the Add saltbk
indicator lights up.

							This washer-disinfector can be fitted
with a top and bottom basket or a
mobile unit. Various inserts and special
baskets are also available for a wide
variety of instruments and utensils.
Select baskets and inserts which are
appropriate for the application.
Notes on the individual areas of
application and examples of loading
are given on the following pages.
Before starting a programme you
should carry out a visual check on
the following:
– Is everything correctly
loaded/connected for cleaning?
– Are the lumen or necks of hollow
instruments positioned so that water
can access them unhindered?
– Are the spray arms clean and do
they rotate freely?
–
Are the filters clean? Remove any
coarse soiling and clean them
properly if necessary.
–
Is the adapter connecting the water
supply to the spray arms/jets
correctly connected?
–
Are all chemical containers filled
sufficiently?At the end of each programme:
–Carry out a visual check of the load
for cleanliness.
–Check that all hollow instruments are
still securely located on their jets.
,Any instruments that have
become disconnected from the
adapters during processing must be
re-processed.
–Are the lumen of hollow instruments
completely clean and clear of
contamination?
– Check that jets and connectors are
securely connected to the baskets or
inserts.
