Take care when handling liquids
such as detergents, neutralizing
agents, wetting agents and rinse aids.
These may contain irritant or corrosive
ingredients, acids or alkalis. Never use
any organic solvents, as the danger of
explosion exists. Wear protective
gloves and goggles. The
manufacturer’s safety conditions must
be observed at all times.
The water in the machine must not
be used as drinking water.
Be careful when sorting items with
sharp pointed ends. Position them
in the machine so that you do not hurt
yourself or create a danger for others.
When using this machine regard
the high temperatures and be
especially careful not to scald or burn
yourself. When opening the door
bypassing the electrical lock, a danger
of burning, scalding and corrosion
exist. Let mobile units, inserts and
cleaned items cool before touching
them. Any water which may remain in
containers will be very hot and must be
emptied into the wash cabinet.
After drying with the TA drying unit
open the door to allow the items
and inserts to cool.
Do not touch the heating elements
(under the wide area filter) during
or directly after the end of a program,
you could burn yourself. They remain
hot for some time after the program
end.
If the boiler has been programmed
to "BOILER READY", be particularly
careful of hot water and steam when
opening the door. Danger of burning or
scalding. The water inlet pipe to the
wash cabinet is located, as viewed
from the unclean side, underneath the
basket runner on the left hand side.

The following points should be
observed to assist in maintaining
quality standards, for critical lab
glassware, to protect patients, and to
avoid damage to the loads being
cleaned.
Use only Miele approved cleaning
agents with this machine. Use of
unsuitable cleaning agents could
adversely affect the components of the
machine. Damages resulting from using
unsuitable cleaning agents are not
covered by the warranty.
Pre-treating (e.g. with cleaning
agents), certain soiling and
cleaning agents with a chemical
interaction, can cause foam. For
pre-treatment and/or cleaning only use
low-sudsing detergents which have
been approved by Miele. Suds can
have an adverse effect on the operation
of the machine.
After START has been pressed the
program must not be interrupted
by pressing the I-0 button. A program
should not be interrupted since the
result may be effected. Otherwise the
program must be repeated.
When a chemical additive is
recommended, the manufacturer of
the machine takes no responsibility for
the effect of the chemical on the items
being cleaned.
The machine must only be
operated with water and the
recommended cleaning agents.
Organic solvents must not be used in
the machine as there is the danger,
under certain circumstances, of
explosion and damage to rubber and
synthetic materials. Follow the dosage
recommendations of the cleaning
agent’s manufacturer.
In critical applications where very
high requirements have to be met,
it is strongly recommended that all the
relevant factors for the process, such
as cleaning agent, quality of water, etc.
are discussed with the Miele
Applications Specialists.
If the cleaning result is subject to
particularly stringent requirements
(e.g. chemical analysis, specialized
processes), a regular quality control
test should be carried out by the user to
ensure that the required standards of
cleanliness are being achieved.
The cleaning standard in the
routine use must be verified by the
user. The process should be checked
regularly using thermoelectric and
documented results.
IMPORTANT SAFETY INSTRUCTIONS

In operating level C the AWK (optional)
attributes a fixed program place to a
mobile unit with valid coding.
Program places 1-15 are reserved for
the AWK automatic mobile unit
recognition.
The unit coding (on the mobile unit) and
the program place with the
corresponding program (in the
"Profitronic" electronic control unit) must
match.
^Each mobile unit must be coded
before being used for the first time.
See "Mobile unit coding".
^The wash program through which the
mobile unit is coded has to be
assigned to the relevant program
place.
Program place changes, see the
"System function - Selector switch
organization" section in the
Programming Manual.
Important!
Before starting the program with the
"Start" button 6, check that the
program needed for this mobile unit
is displayed.
Otherwise insufficient wash results
may occur!
Always check that programs for
mobile units with AWK (on fixed
program places) are not exchanged.
Mobile unit coding
The automatic mobile unit recognition
feature assigns a program place to a
mobile unit. The mobile units must be
coded with a magnetic strip, via a bit
combination. In operating level C the
only program available for a coded
mobile unit is the one assigned to the
corresponding program place.
When a coded mobile unit is inserted in
the machine and the door closes, the
automatic mobile unit recognition
selects the assigned program. Be sure
no small items connect to the magnetic
strip.
^Press 6to start the program.
The coding is made up of 5 bits:
–Bits 1 to 4 define the mobile unit
code,
–Bit 5 serves as a control (Parity-Bit).
Bit 6 controls the volume of water intake
and the circulation pump for mobile
units with side coupling. This setting
cannot be changed!
Mobile units without side coupling are
coded with tracks which do not contain
Bit 6!
Automatic mobile unit recognition (AWK)
16

Mobile unit coding strip
15 different codes can be set. They are
assigned to program places 1 to 15.
Under "System function - Selector
switch organization" the matching
programs have to be put into the first
15 program places.

The coded total must be an even
number. Bit 6 is not included in this
calculation.
If the coded total equals an odd number
the message CHECK MOBILE UNIT
RECOGNITION will appear. If the mobile
unit code equals 0, the message NO
MOBILE UNIT RECOGNITION will
appear. In both cases the program
cannot be started. The mobile unit
recognition must be reset.
Setting mobile unit coding
To set or alter the coding of a mobile
unit with automatic recognition (AWK)
proceed as follows:
^Unscrew the track with an AWK (allen
wrench) and remove it from the
retainer.
^Remove the magnetic strip from the
track.
Automatic mobile unit recognition (AWK)
17

^Set the program place coding.
^Put the magnetic strip back in the
track.
Important:
The magnetic strip must be placed
in the track so that the Bit coding,
set according to the chart, is visible
through the round windows of the
track.
^Place the track in the holder of the
mobile unit and screw firmly in place.
Bit 6 is not an integral part of the
modifiable magnetic strip.
Make sure that you code mobile
units with side coupling to a track
where Bit 6 is set to I.
Mobile units without side coupling
must be coded with a track that
does not have Bit 6.
The magnetic strips on the G 7825 /
G 7826 must have gray magnets.
The magnetic strips on the G 7827 /
G 7828 must have black magnets.

Application
19

Loading tips
Select mobile units, baskets and
inserts appropriate for the
application.
^Load the items to be washed so that
water can access all surfaces. This
ensures that they will be properly
cleaned.
^Do not place items to be cleaned
inside other pieces where they may
be concealed.
^Hollow vessels such as beakers,
measuring cylinders, flasks, etc.
should be inverted and placed in the
correct inserts so that water can flow
in and out unrestricted. A cover net
can be used to reduce the risk of
movement during the wash process.
^Use a cover net (e.g. an A 2) or
mesh tray to secure small and/or
lightweight items to prevent them
from blocking the spray arms or
being caught in the magnetic strip on
the automatic mobile unit recognition
system.
^Deep based items should be placed
at an angle to allow water to run off
easily.
^Tall, narrow pieces should be placed
in the center of the baskets. This
ensures good water coverage.
^Mobile units with an adapter must
engage correctly.
^Engage inserts correctly into the
module carts.
^The spray arms must not be blocked
by tall items or items which hang
down in their path. If necessary,
manually rotate the arms to test.
^Petri dishes and the similar should be
placed in the correct insert with the
soiled side facing the center.
^Insert pipettes with the pointed end
downwards.
^Quarter inserts should be placed as
close to the middle of the unit as
possible.
^Glassware should not stick out of the
door area.
