This Miele laboratory glassware washer can be used to reprocess
laboratory glassware and laboratory utensils with water based media.
The process includes cleaning, rinsing and where required
disinfection and drying. Due to the wide variety of laboratory
glassware and laboratory utensils on the market, it may be necessary
in some cases to establish whether it is suitable for reprocessing in a
laboratory glassware washer. This will depend on its use and the type
of soiling present as well as disinfection parameters. Please also
observe information provided by the manufacturer of the laboratory
glassware and laboratory utensils.
Laboratory glassware and laboratory utensils suitable for
reprocessing are for example:
– Vessels such as test tubes, beakers, flasks, cylinders, etc.
– Measuring vessels such as measuring cylinders, pipettes,
volumetric flasks, etc.
– Dishes such as petri dishes, watch glasses, etc.
– Plates such as slides, sequencing plates, etc.
– Small items such as lids, spatulas, magnetic stirring rods, stoppers,
etc.
– Other items such as funnels, pipe/hose pieces, etc.
Examples of application areas:
– Laboratories in schools, colleges and universities,
– Research, quality assurance, development, technology and
production.
– Different areas of inorganic, organic, analytical and physical
chemistry,
– Biology, microbiology and biotechnology,
– Hospital laboratories.
Laboratory glassware and laboratory utensils for reprocessing are
referred to as the wash load if they are not more closely defined.
Processing conditions must be suitable for the wash load and for the
type of soiling. Process chemicals must be suitable for the type of
soiling and for methods of analysis being used.
The use of a suitable carrier (wash carts, baskets, modules, inserts,
etc.) is important to ensure the adequate cleaning of the load.
Examples are given in the section "Areas of application".
This machine is programmed to carry out the final rinse with mains
water or with processed water of a quality to suit the application (e.g.
purified water, fully demineralized water or demineralized water).
It is particularly important to ensure the appropriate water quality for
the rinse and final rinse of items for analytical purposes.

Intended use
9
The machine can be qualified for process validation.
Spray pressure and spray arm monitoring
The machine has a sensor for monitoring spray pressure in order, for
example, to detect pressure fluctuations due to misloading or foam in
the water circulation system. Spray pressure monitoring is set at the
factory to be active in the "Cleaning" and "Final rinse" wash blocks.
The spray pressure monitoring result is documented together with an
optional process documentation.
Spray arm speed can also be monitored, e.g. for prompt detection of
blockages due to misloading or foam in the water circulation system.
Spray arm speed monitoring can be activated or deactivated via the
programmable settings.

 The machine is designed to operate with water and the
recommended process chemicals only. Organic solvents or
flammable liquid agents must not be used in it!
This could cause an explosion, property damage due to the
destruction of rubber and plastic components, and the resulting
leakage of liquids.
 The water in the cabinet must not be used as drinking water.
 Do not lift the machine by protruding parts such as the control
panel or the opened service flap as these could be damaged or torn
off.
 Do not sit or lean on the opened door. This could cause the
machine to tip or become damaged.
 Be careful when sorting items with sharp, pointed ends. Position
them in the machine so that you will not hurt yourself or create a
danger for others.
 Broken glass can result in serious injury when loading or
unloading. Broken glass items must not be processed in the machine.
 When operating the machine, beware of the high temperatures
involved. If you bypass the electrical lock to open the door, there is a
danger of scalding and heat or chemical burns. If disinfectants have
been used, there is also the danger of inhaling toxic vapour.
 Should personnel accidentally come into contact with toxic
vapours or processing chemicals, consult the manufacturer's safety
data sheets for emergency procedures.

Warning and Safety Instructions
16
 Always allow wash carts, baskets, modules, inserts, and loads to
cool down before unloading. Any water remaining in concave items
could still be very hot. Empty them into the wash cabinet before
taking them out.
 Never clean the machine or surrounding area with a water hose or
a pressure washer.
 The machine must be disconnected from the mains electricity
supply before any maintenance or repair work is carried out.
Quality assurance
 If it is necessary to interrupt a program in exceptional
circumstances, this may only be done by authorised personnel.
 The standard of reprocessing must be routinely confirmed by the
user. The process should be validated on a regular basis, and
checked against documented control results.
 For thermal disinfection, the appropriate temperatures and holding
times, as required by microbiological and public health standards and
guidelines, must be used to achieve the required degree of infection
control.
 Make sure items being washed are suitable for machine
processing and are in good condition. Plastic items must be thermally
stable. Nickel plated items and anodised aluminum items can be
machine processed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.
 Under certain circumstances process chemicals can cause
damage to the machine. Always follow the recommendations of the
process chemical manufacturers.
In case of damage or doubt about compatibility, please consult with
Miele.
 Process chemicals containing chlorine can damage the elastomers
of the machine.
If the use of process chemicals containing chlorine is required, a
maximum temperature of 70°C in the program block "Main wash" is
recommended (see program overview).
In machines equipped with special oil-resistant elastomers (ex works)
for oil and grease applications process chemicals containing
chlorides may not be used!
 Abrasive substances must not be placed in the machine as they
could cause damage to the mechanical components of the water
supply. Any residues of abrasive substances on items to be washed
must be removed without trace before reprocessing in the machine.

Warning and Safety Instructions
17
 Pre-treating (e.g. with cleaning agents or disinfectants), some
types of soiling and the interaction of certain process chemicals can
cause foaming. Foam can have an adverse effect on the cleaning and
disinfection results obtained.
 The process must be set so that no foam escapes the wash
compartment. Escaping foam jeopardizes the safe operation of the
machine.
 The process must be checked regularly in order to detect any
foaming.
 To prevent material damage to the machine and accessories used
from the effects of process chemicals, soiling and their interaction,
follow the notes in chapter "Chemical Processes and technology".
 Even when a chemical additive (e.g. cleaning chemical) is
recommended on technical application grounds, the machine
manufacturer takes no responsibility for the effect of such chemicals
on the material of the items being cleaned.
Note that formulation changes, storage conditions, etc., that are not
disclosed by the chemical manufacturer may adversely affect the
cleaning results obtained.
 When using process chemicals, always follow the instructions of
the chemical's manufacturer. The process chemicals must only be
used for the application it is designed for and in the situation
specified to avoid material damage and such dangers as a severe
chemical reaction (e.g. an explosive oxyhydrogen gas reaction).
 Always follow the relevant manufacturer's instructions on storage
and disposal of process chemicals.
 For critical applications, where very stringent reprocessing
requirements have to be met, it is strongly recommended that all
process-related factors (processing chemicals, water quality, etc.) are
discussed in advance with Miele.
 For applications that demand especially stringent cleaning and
rinsing results, the operator must ensure that quality control occurs
on a regular basis to meet the standards involved.
 Wash carts, baskets, modules and inserts should only be used for
the purpose for which they are designed for.
Hollow items must be thoroghly cleaned, internally and externally.
 Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
 Empty all containers and hollow utensils before loading them into
the machine.

Warning and Safety Instructions
18
 The amount of residual solvents and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21°C.
 Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 To avoid corrosive damage, make sure the stainless steel housing
does not come into contact with solutions or steam containing
hydrochloric acid.
 After any plumbing work the water pipework to the machine will
need to be vented. If this is not done, components can be damaged.
 The gaps between a built-in machine and adjacent cabinetry must
not be filled with silicone sealant as this could compromise the
ventilation of the circulation pump.
