damage to rubber and plastic
components, which in turn allows liquid
substances to leak out.
~ Do not stand, sit or lean on the
opened machine door.
~ Do not touch the heating elements
during or directly after the end of a
program, burns could result. The
elements remain hot for some time after
the end of the program.
~ The water in the machine must not
be used as drinking water.
~ Be careful when sorting items with
sharp, pointed ends. Carefully position
these items in the machine, so that you
will not hurt yourself or create a danger
for other operators.
~ 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.
~
If toxic chemical substances can
form in the wash water during
processing (e.g. aldehydes in the
disinfection agent), the door seal and, if
applicable, the function of the steam
condensor must be checked regularly.
In that case, opening the lab washer
door during a program interruption can
be dangerous.
~ If you are exposed to toxic vapors or
processing chemicals, consult the
manufacturer's material safety data
sheets for emergency procedures.
~ Always allow mobile units, modules,
inserts, and loads to cool before
removing. Be sure to empty any water
from concave items into the wash
cabinet before removing.
~ After drying with the TA drying unit
open the door to allow the items and
inserts to cool.
5
IMPORTANT SAFETY INSTRUCTIONS
~ 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.
~ Steam heating is permissible up to a
pressure of 145 psi. This corresponds
to a water steam temperature of 354°F
(179 °C).
~ Never clean the machine or near its
vicinity with a water or high pressure
hose.
~ Avoid inhaling powder products.
They can cause burning in the mouth
and throat if swallowed, and can inhibit
breathing.
~ Before servicing, disconnect the
power supply by either removing the
fuse, unplugging the unit or manually
"tripping" the circuit breaker.
~ Whenever work is conducted on the
tap water network, the water supply line
to the washer must be cleared of air.
Failure to do so can result in damage to
the water softener.
The following points should be
observed to assist in maintaining
quality standards for critical labware
and to avoid damage to the loads
being cleaned.
6
~ For this type of cleaning, the
program must not be interrupted until
completion. In other words, the On/Off
Button must not be used. Interruptions
should also be avoided for all other
programs, such as during performance
testing, because this can negatively
affect the cleaning and rinsing results.
After any interruption, the program
should be restarted from the beginning.
~ Only use cleaning agents
formulated for special processes and
approved by Miele for use with this
machine. Use of unsuitable cleaning
agents could adversely affect the

can create suds, as can certain rinsing
agents. 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 cleaning process.
~ 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.
IMPORTANT SAFETY INSTRUCTIONS
~ It is the responsibility of the operator
to routinely check that the required
cleaning standards are being met.
Therefore, results need to be regularly
tested and documented, both thermo
electrically and through inspection. For
thermo chemical processes, additional
testing is required using chemical or
biological indicators.
~ The performance of the cycles was
tested using Neodisher products. The
use of other products is not
discouraged but may not yield identical
results. Please be aware that changes
in formulation, storage conditions, etc.
which may not be publicized by the
chemical manufacturer can have a
negative effect on cleaning results. and
are not the responsibility of the machine
manufacturer.
~ The process must be set so that no
foam escapes the wash compartment.
Escaping foam jeopardizes the safe
operation of the lab washer.
~ The process must be checked
regularly in order to detect any
foaming.
~ In order to prevent damage to the
lab washer and any accessories
through processing chemicals or dirt as
well as any interaction between them,

Automatic mobile unit recognition (AWK)
In operating level C the AWK 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.
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 6 to start the program.
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.
16
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)

15 different codes can be set. They are
assigned to program places 1 to 15.
To set or alter the coding of a mobile
unit with automatic recognition (AWK)
proceed as follows:
Under "System function - Selector
switch organization" the matching
programs have to be put into the first
15 program places.

Effects of Processing Chemicals
General information
Effects
Action
Damage to elastomer (seals and hoses)
or plastic components of the lab
washer may cause the materials to
swell, shrink, harden or become brittle,
possibly causing cracks to form in the
materials. This will impair their function,
which will generally lead to leaks.
– Find and correct the causes of the
damage.
See "Connected processing
chemicals", "Soiling" and "Reactions
between processing chemicals and
soils" for more information.
Strong foaming during the program
prevents proper cleaning and rinsing of
the load. Foam escaping from the wash
compartment can result in damage to
the lab washer.
If foaming occurs, the cleaning process
is not standardized and not validated.
– Find and correct the cause of the
foaming.
– The process must be checked
regularly in order to detect any
foaming.
See "Connected processing
chemicals", "Soiling" and "Reactions
between processing chemicals and
soils" for more information..
Stainless steel corrosion in the wash
compartment and/or accessories may
appear in various ways:
– rust formation (red spots / stains),
– black spots / stains,
– white spots / stains (smooth surface
is slightly corroded).
Corrosion that forms holes can result in
leaks in the lab washer. Depending on
the application, the corrosion may
impair the cleaning and rinsing results
(laboratory analysis) or cause corrosion
of the load (stainless steel).
