Keep the operating instructions in a safe place.

Correct application

 Use of the machine is only permitted for the applications expressly

approved in the operating instructions. Alterations or conversion of
the machine, or using it for purposes other than those for which it
was intended, are not permitted and could be dangerous.
The cleaning and disinfection processes are only designed for labor­atory glassware and utensils which are designated as reprocessable
by the manufacturer. The information provided by the manufacturer of
the load items must be observed.

 This washer-disinfector is intended for indoor use only.
 The machine is equipped with a special lamp to cope with particu-

lar conditions (e.g. temperature, moisture, chemical resistance, abra­sion resistance and vibration). This special lamp must only be used
for the purpose for which it is intended. It is not suitable for room
lighting. Replacement lamps may only be fitted by the Miele Cus­tomer Service Department.

Risk of injury

Please pay attention to the following notes to avoid injury

 This machine must be commissioned, serviced and repaired by a

Miele authorised and trained service technician only. To ensure com­pliance with Good Laboratory Practice guidelines, Miele repair and
maintenance contracts are recommended. Unauthorised repairs can
pose considerable risks to the user.

 Do not install the machine in an area where there is any risk of ex-

plosion or of freezing conditions.

 The electrical safety of the machine can only be guaranteed when

it is correctly earthed. It is essential that this standard safety require­ment is observed and regularly tested. If in any doubt, please have
the electrical installation inspected by a qualified electrician.

16

 A damaged or leaking machine could be dangerous and comprom-

ise your safety. Disconnect the machine from the mains immediately
and call the Miele Service Department.

Warning and Safety instructions

 Label machines which have been taken out of operation and se-

cure them from being switched on again without authorisation. The
machine may only be put back into operation once it has been suc­cessfully repaired by the Miele Customer Service Department.

 Personnel operating the machine should be trained regularly. Un-

trained personnel must not be allowed access to the machine or its
controls.

 Take care when handling chemical agents. These may contain irrit-

ant, corrosive or toxic ingredients.
Please observe the chemical agent manufacturer's safety instructions
and safety data sheets.
Wear protective gloves and goggles.

 Only use process chemicals which have been approved by their

manufacturer for the relevant application. The manufacturer of the
process chemicals is liable for any negative influences on the material
of the load and the machine.

 The machine is designed for operation with water and recommen-

ded additive chemical agents only. Organic solvents and flammable
liquid agents must not be used in it.
This could cause an explosion, damage rubber or plastic components
in the machine and cause liquids to leak out of it.

 The water in the cabinet must not be used as drinking water.
 Be careful when sorting items with 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 unload-

ing. Damaged glass items must not be reprocessed in the machine.

 When using this machine in the higher temperature ranges, be es-

pecially careful not to scald or burn yourself or come into contact with
irritant substances when opening the door. Where disinfecting agents
are used there is a danger of inhaling toxic fumes.

 Where there is a risk of toxic or chemical substances occurring in

or leaking into the suds solution (e.g. aldehyde in the disinfecting
agent), it is essential to regularly check door seals and make sure that
the steam condenser is functioning correctly. Opening the machine
door during a programme interruption carries particular risks in such
circumstances.

 Should personnel accidentally come into contact with toxic va-

pours or chemical agents, follow the emergency instructions given in
the manufacturer's safety data sheets.

 After using the hot air drying unit, open the door to allow the

everything in the cabinet from the load itself to the mobile units, mod­ules and inserts to cool down.

17

Warning and Safety instructions

 Mobile units, modules, inserts and the load must be allowed to

cool down before they are unloaded. Any water remaining in contain­ers could still be very hot. Empty them into the wash cabinet before
taking them out.

 Steam heating is permissible up to a pressure of 1000kPa. This

corresponds to a water steam temperature of 180°C.

 Never clean the machine or near vicinity with a water hose or a

pressure washer.

 The machine must be disconnected from the mains electricity sup-

ply before any maintenance or repair work is carried out.

Quality assurance

The following points should be observed to assist in maintaining
quality standards when processing laboratory glassware and
utensils to avoid damage to the loads being cleaned.

 If it is necessary to interrupt a programme in exceptional circum-

stances, this may only be done by authorised personnel.

 The standard of cleaning and disinfection must be routinely con-

firmed by the user. The process should be validated on a regular
basis, and checked against documented control results.

 For thermal disinfection, use temperatures and temperature holding

times to achieve the required infection prophylaxis in accordance with
current health and safety regulations.

 Make sure items being washed are suitable for machine repro-

cessing and are in good condition. Plastic items must be thermally
stable. Nickel plated items and aluminium items can be machine pro­cessed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.

 Chemical agents can, in certain circumstances, cause damage to

the machine. Always follow the recommendations of the chemical
agent manufacturer.
In case of damage or doubt about compatibility, please contact
Miele.

 Cleaning agents containing chlorine can damage the elastomers of

the machine.
If the use of cleaning agents containing chlorine is required, a max­imum temperature of 75°C in the “Main wash” programme phases is
recommended (see programme chart).
Cleaning agents containing chlorine must not be used in machines
supplied (ex works) with special oil-resistant elastomers for oil and
grease applications.

18

Warning and Safety instructions

 Pre-treatments with cleaning or disinfecting agents can create

foam, as can certain types of soiling and chemical agents. Foam can
have an adverse effect on the cleaning and disinfection 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 su-

pervisor to check foaming levels.

 To avoid the risk of damage to the machine and any accessories

used with it caused by chemical agents, soiling and any reaction
between the two please read the notes in “Chemical processes and
technology”.

 Even when a process chemical, e.g. cleaning agent, is recommen-

ded, the machine manufacturer takes no responsibility for the effect
of such process chemicals on the load.
Please note that changes in product formulation, storage conditions,
etc. which are not announced by manufacturers of process chemicals
may impair the quality of cleaning results.

 When using process chemicals, always consult the instructions is-

sued by individual manufacturers. Process chemicals must only be
used for the purpose they are designed for by the manufacturer to
avoid any material damage or the occurrence of very strong chemical
reactions (e.g. oxyhydrogen explosion).

 Always follow the relevant manufacturer's instructions on storage

and disposal of chemical agents.

 Particles≥200μm are removed by the filters in the wash chamber.

Smaller particles may find their way into the circulation system.

 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 chemical agents, water quality etc. are discussed
with the Miele Application Technology specialists.

 If the cleaning result is subject to particularly stringent require-

ments, e.g. in chemical analysis, the operator must carry out regular
quality control to ensure that required standards of cleanliness are
being achieved.

 Mobile units, modules and inserts should only be used for the pur-

pose they are designed for.
Hollow instruments 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.

19

Warning and Safety instructions

 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.

 Chlorous 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 vented. If this is not done, components can be damaged.

 Follow the installation instructions in the operating and installation

instructions.

Using accessories

 Only Miele accessories should be connected to this machine. They

must be suitable for the application they are required for. Consult
Miele for details on the type of accessories that can be used.

 Only use Miele mobile units, baskets and inserts with this washer-

disinfector. Using mobile units and inserts made by other manufac­turers, or making modifications to Miele accessories can cause un­satisfactory cleaning results, for which Miele cannot be held liable.
Any resultant damage would not be covered by the guarantee.

 Only use process chemicals which have been approved by their

manufacturer for the relevant application. The manufacturer of the
process chemicals is liable for any negative influences on the material
of the load and the machine.

General information

Areas of application

Load carriers

E9xx load carriers
from older model
ranges

Pictograms for manual programme selection

The machine can be fitted with a variety of load carriers, which can
be combined with a variety of modules and inserts depending on the
type and shape of load items requiring cleaning and disinfection.

Select load carriers and other equipment, e.g. irrigation connect­ors, which are appropriate for the application.

Information on the individual areas of application can be found on the
following pages, as well as in the operating instructions for the load
carriers.

Miele offers suitable load carriers for all areas of application defined
in “Appropriate use”, such as mobile units, modules, inserts and spe­cial irrigation connectors. More information can be obtained from
Miele.

Load carriers from older model ranges with the designation E9xx can
be used in the machine.
A857 retrofit kits for the mobile units are available from Miele.

When you select a programme manually on the machine, you must
select the relevant mobile unit first. Pictograms representing the mo­bile units are shown on the display. The pictograms assigned to the
mobile units in the A5xx model range are listed in the operating in­structions for the mobile units.

Mobile unit/module combinations from the A5xx model range

The pictogram and name of the mobile unit can be found on a strut
on the front of the mobile unit. The model shown is the mobile unit
without modules inserted.
For different module combinations in the A500 and A503 mobile
units, several pictograms can be displayed (see operating instructions
for the mobile unit).

Fixed mobile units from the A5xx model range

The pictogram and name of the mobile unit can be found on the front
of the mobile unit.

Areas of application

Preparing the load

Only load items which have been declared by their manufacturer as
suitable for machine reprocessing may be processed. The manu­facturer’s specific reprocessing instructions must be observed.

 Contaminated load items pose a health risk.
Contaminated load items can result in various hazards to the

health, which can lead to infections, poisoning, injuries and more
depending on the type of contamination.

When working with contaminated load items, ensure that all neces­sary measures are taken to protect personnel.

Wear protective gloves and use suitable aids.

– Arrange the load so that wash water can access all surfaces. This

ensures thorough and proper cleaning.

– Do not place load items inside other items where they may be con-

cealed.

– Do not place load items so close together that cleaning is

hampered.

– Lumened load items must be thoroughly cleaned, internally and ex-

ternally, by the wash water. Depending on the load, special irriga­tion connectors may be required here, e.g. nozzles, irrigation
sleeves or adapters.

– Ensure that load items with long, narrow, hollow sections can be

flushed through properly before placing them in inserts or connect­ing them to an irrigation connector.

– Lumened instruments should be inverted and placed in the correct

mobile units, modules and inserts to ensure that wash water can
flow in and out of them unrestricted.

– Deep-sided load items should be placed at an angle to make sure

the wash water runs off them freely.

– Tall, narrow lumened instruments should be placed in the centre of

the mobile units if they are not going to be sprayed directly. This
ensures the insides of the lumened instruments are more easily ac­cessed by the water jets.

– Take apart any load items which can be dismantled according to

the manufacturer’s instructions and reprocess the individual parts
separately from each other.

– Lightweight load items should be secured with a cover net such as

theA 6 to prevent them from spinning around in the wash chamber
and blocking the spray arms.

26

– Only reprocess small items and micro components in special in-

serts, mesh trays with lids or mesh inserts.

– The spray arms must not be blocked by load items which are too

tall or which hang down in their path.

Areas of application

– Broken glass can result in serious injury when loading or unloading.

Damaged glass load items must not be reprocessed in the ma­chine.

– Nickel and chrome-plated load items, and load items made of alu-

minium, require special procedures and are not generally suitable
for machine reprocessing. Special process conditions are required
for these load items.

– With items which are made entirely or partly of plastic, observe the

maximum thermal stability for the items and select an appropriate
programme or adjust the temperature of the programme.

Preparing the load

 Danger of explosion due to flammable gases.
Flammable solvents with a flash point below 21°C outgas and can

generate a flammable mix of gases.
Only load the machine with load items which are wetted with traces

of solvents at most.
Start the reprocessing programme as soon as the machine has

been loaded with the wetted load items.

 Risk of damage due to solvents.
Solvents with a flash point above 21°C can damage elastomers

and plastics. The machine could leak as a result of this.
Only load the machine with load items which are wetted with traces

of solvents at most.
Start the reprocessing programme as soon as the machine has

been loaded with the wetted load items.

 Risk of damage due to corrosion.
Chloride solutions, particularly hydrochloric acid, and ferrous ma-

terials that can rust or corrode cause corrosion on the stainless
steel of the machine and the load carrier.

Do not introduce any chloride solutions into the machine.
Do not introduce any ferrous materials that can rust or corrode into

the machine.

 Risk of infection.
Microbiological material, pathogens and facultative pathogens, and

genetically modified material can cause infections or environmental
damage.

Before reprocessing by machine, decide whether the load contam­inated in this way needs to be sterilised.
