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 167°F/75°C in the "Cleaning" program
blocks is recommended (see program chart).
In machines equipped with special oil-resistant elastomers (from the
factory) 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.
 Pre-treatments with cleaning agents can create foam, as can
certain types of soiling and process chemicals. Foam can have an
adverse effect on the cleaning result.
 Processes must be set up such that foam cannot escape from the
wash cabinet. It would hinder the correct functioning of the machine.
 The process used must be monitored on a regular basis by the
supervisor to check foaming levels.
 To avoid the risk of damage to the machine and its accessories
caused by process chemicals, soiling and any reaction between the
two, please read the notes in "Chemical Processes and Technology."
 Even when a process chemical is recommended on technical
application grounds, it does not imply that the manufacturer of the
machine accepts liability for the effect of the chemical on the items
being cleaned.
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 the cleaning result.

IMPORTANT SAFETY INSTRUCTIONS
12
 When using a process chemical it is essential that the
manufacturer's instructions are followed. The process chemical 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
explosive chemical reaction (e.g. an explosive oxyhydrogen gas
reaction).
 Always follow the manufacturer's instructions on storage and
disposal of process chemicals.
 In critical applications where very stringent requirements have to
be met, it is strongly recommended that all the relevant factors for the
process, such as process chemicals, water quality, etc., are
discussed 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.
 The mobile units, baskets, modules and inserts that hold the wash
load must be used only as intended.
Hollow items must be thoroughly 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 any containers or utensils before loading them.
 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 70°F (21°C).
 Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 Ensure that solutions or steam containing chlorides or hydrochloric
acid do not come into contact with the stainless steel outer casing of
the machine in order to avoid any damage through corrosion.
 After any plumbing work, the water pipework to the machine will
need to be primed. 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 to the circulation pump.
 Follow the installation instructions in the operating and installation
instructions.

Laboratory glassware and laboratory utensils suitable for
reprocessing include a wide range of items, for example:
– Vessels such as test tubes, beakers, flasks, etc.
– Measuring vessels such as measuring cylinders, pipettes,
volumetric flasks, etc.
– Dishes such as petri dishes, watch glasses, etc.
– Small items such as lids, spatulas, magnetic stirring rods, stoppers,
etc.
– Other items such as funnels, 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,
– 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 (mobile unit, basket, module, insert, etc.)
is important to ensure adequate processing 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 used for analytical purposes.
Miele can provide IQ and OQ validation support.
The machine fulfills the requirements of the EU Machinery Directive
