If the machine is built under, it must only be installed under acontinuous worktop run which is firmly secured to adjacent units toimprove stability.


15

The electrical safety of this machine can only be guaranteed whencorrectly earthed. It is essential that this standard safety requirementis met. If in any doubt, please have the on-site wiring system testedby a qualified electrician. Miele cannot be held liable for theconsequences of an inadequate earthing system (e.g. electric shock).

A damaged or leaking machine could be dangerous andcompromise your safety. Disconnect the machine from the mainsimmediately and call the Miele Service Department.

Personnel operating the machine should be trained regularly.Untrained personnel must not be allowed access to the machine orits controls.

Only use chemical agents which have been approved by theirmanufacturer for use in the application you are using. The chemicalagent manufacturer is responsible for any negative influences on thematerial the load is made from and for any damage they may causeto the machine.

Take care when handling chemical agents. These may containirritant, corrosive or toxic ingredients. Please observe the chemical agent manufacturer's safety instructionsand safety data sheets. Wear protective gloves and goggles.

The machine is designed for operation with water andrecommended additive chemical agents only. Organic solvents andflammable liquid agents must not be used in it.This could cause an explosion, damage rubber or plastic componentsin the machine and cause liquids to leak out of it.

The water in the cabinet must not be used as drinking water. Do not lift the machine by protruding parts such as the controlpanel or the opened service flap as these could be damaged or tornoff.

Do not sit or lean on the opened door. This could cause themachine to tip up and be damaged or cause an injury.

Be careful when sorting items with sharp pointed ends andpositioning them in the machine that you do not hurt yourself orcreate a danger for others.

Broken glass can result in serious injury when loading orunloading. Broken glass items must not be processed in the machine.

When using this machine in the higher temperature ranges, beespecially careful not to scald or burn yourself or come into contactwith irritant substances when opening the door. Where disinfectingagents are used there is a danger of inhaling toxic fumes.


16

Where there is a risk of toxic or chemical substances occurring inor leaking into the suds solution (e.g. aldehyde in the disinfectingagent), it is essential to regularly check door seals and make sure thatthe steam condenser is functioning correctly. Opening the machinedoor during a programme interruption carries particular risks in suchcircumstances.

Should personnel accidentally come into contact with toxicvapours or chemical agents, follow the emergency instructions givenin the manufacturer's safety data sheets.

Mobile units, baskets, modules, inserts and the load must beallowed to cool down before they are unloaded. Any water remainingin containers could still be very hot. Empty them into the washcabinet before taking them out.

Never clean the machine or near vicinity with a water hose or apressure washer.

The machine must be disconnected from the mains electricitysupply before any maintenance or repair work is carried out.


17

Quality assuranceThe following points should be observed to assist in maintainingquality standards when processing medical devices, in order toprotect patients, and to avoid damage to the loads beingcleaned.

If it is necessary to interrupt a programme in exceptionalcircumstances, this may only be done by authorised personnel.

The standard of cleaning and disinfection in the disinfectionprogrammes must be routinely confirmed by the user. The processmust be thermo-electrically validated on a regular basis, and checkedagainst documented control results. Chemical disinfection procedures should also be validated using bioindicators.

For thermal disinfection, use temperatures and temperature holdingtimes to achieve the required infection prophylaxis in accordance withcurrent health and safety regulations.

Make sure items being washed are suitable for machinereprocessing and are in good condition. Plastic items must bethermally stable. Nickel plated items and aluminium items can bemachine processed using special procedures only.Items containing iron, and soiling containing residual rust must not beplaced in the cabinet.

Medical products are processed by means of thermal disinfection. Disinfection of heat-sensitive items, e.g. theatre shoes, can be carriedout using a chemical disinfecting agent. Miele Service will set up aspecial programme for this purpose. The range of effectivedisinfection is based on claims made by the producer of thedisinfecting agent. Their instructions on handling, use andeffectiveness must be observed. The use of chemical disinfectionprocedures is the responsibility of the operator.Chemical disinfection processes are not suitable for the reprocessingof medical products.

Chemical agents can, in certain circumstances, cause damage tothe machine. Always follow the recommendations of the chemicalagent manufacturer. In case of damage or doubt about compatibility, please contactMiele.

Instrument care products based on paraffin oils (white oils) candamage the elastomers and plastic in the machine. Such careproducts must not be dispensed as chemical agents in this machineeven if they are recommended for machine use by the care productmanufacturer.


18

Abrasive substances must not be placed in the machine as theycould cause damage to the mechanical components of the watersupply. Any residues of abrasive substances on items to be washedmust be removed without trace before reprocessing in the machine.

Pre-treatments with cleaning or disinfecting agents can createfoam, as can certain types of soiling and chemical agents. Foam canhave an adverse effect on the disinfection and cleaning result.

Processes must be set up such that foam cannot escape from thewash cabinet. It would hinder the correct functioning of the machine.

The process used must be monitored on a regular basis by thesupervisor to check foaming levels.

To avoid the risk of damage to the machine and any accessoriesused with it caused by chemical agents, soiling and any reactionbetween the two please read the notes in "Chemical processes andtechnology".

Where a chemical agent is recommended on technical applicationgrounds (e.g. a cleaning agent), this does not imply that themanufacturer of the machine accepts liability for the effect of thechemical on the items being cleaned. Please be aware that changes in formulation, storage conditions etc.which may not be publicised by the chemical manufacturer, can havea negative effect on the cleaning result.

When using a chemical agent it is essential that the manufacturer'sinstructions are followed. The chemical agent must only be used forthe application it is designed for and in the situation specified, toavoid material damage and such dangers as a severe explosivechemical reaction (e.g. an explosive oxyhydrogen gas reaction).

Always follow the relevant manufacturer's instructions on storageand disposal of chemical agents.

Particles ≥ 0.8 mm are removed by the filters in the wash cabinet.Smaller particles may find their way into the circulation system. Forthis reason, processing of loads with narrow openings requiresadditional filtering of the wash water.

In critical applications where very stringent requirements have tobe met, it is strongly recommended that all the relevant factors for theprocess, such as chemical agents, water quality etc. are discussedwith the Miele Application Technology specialists.

If the cleaning result is subject to particularly stringentrequirements, a regular quality control test should be carried out bythe user to ensure that required standards of cleanliness are beingachieved.

The mobile units, baskets, modules and inserts that hold the loadmust be used only as intended.Hollow items must be thoroughly cleaned, internally and externally.


19

Secure small and light items with cover nets or place in a meshtray 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 thecabinet should be minimal.There should be no more than a trace of any solvents with a flashpoint of below 21 °C.

Chlorous solutions, in particular hydrochloric acid, must not beplaced in the cabinet.

Ensure that solutions or steam containing chlorides or hydrochloricacid do not come into contact with the stainless steel outer casing ofthe machine in order to avoid any damage through corrosion.

After any plumbing work the water pipework to the machine willneed to be vented. If this is not done, components can be damaged.

The gaps between a built-in machine and adjacent cabinetry mustnot be filled e.g. with silicone sealant as this could compromise theventilation to the circulation pump.

Follow the installation instructions in the operating and installationinstructions.


20

Using accessories

Only Miele accessories should be connected to this machine. Theymust be suitable for the application they are required for. ConsultMiele for details on the type of accessories that can be used.

Only use Miele mobile units, baskets, modules and inserts with thiswasher-disinfector. Using mobile units, baskets, modules and insertsmade by other manufacturers, or making modifications to Mieleaccessories can cause unsatisfactory cleaning results, for whichMiele cannot be held liable. Any resultant damage would not becovered by the guarantee.

Water softener

29

Water hardnessIn order to achieve good cleaning results, the machine needs tooperate with soft water. Hard water results in the build-up of calciumdeposits on the load and in the machine.

Mains water with a water hardness of 0.7 mmol/l (4 °dH) must besoftened. This occurs automatically in the built-in water softener. The water softener must be set to the exact hardness of the mainswater (see "Water softener/Setting the water hardness").

Your local water authority will be able to tell you the exact degree ofhardness in the mains water supply.For future servicing it is useful to make a note of your waterhardness level. Enter your water hardness level here:

________________________mmol/l or °dH

The water softener must be reactivated at regular intervals. Thisrequires special reactivation salt (see "Water softener/Filling the saltreservoir"). Reactivation is carried out automatically during aprogramme sequence.

If the hardness level of your water is constantly less than 0.7 mmol/l (= 4 °dH), salt is not required for the water softener. The waterhardness level must, however, still be set.

Filling the salt reservoirUse only special, coarse-grained reactivation salt with a granule sizeof approx. 1 - 4 mm.Do not under any circumstances use other types of salt such as tablesalt, agricultural or gritting salt. These may contain insoluble additiveswhich can impair the functioning of the water softener.

Inadvertently filling the salt reservoir with cleaning agent willcause serious damage to the water softener.Before filling the salt container make sure that you have picked upthe right packet of reactivation salt.

Open the door to an angle of approx. 45°. This ensures that the saltflows into the reservoir more easily.

Press the yellow button on the salt reservoir with the symbol onit in the direction of the arrow. The flap will spring open.

Lift up the funnel.

The reservoir takes approx. 1.4 - 2 kg of salt, depending on the typeof salt and how much is left in.

Water softener

33

Do not fill the reservoir with water.The reservoir could overflow when filled with salt.

Add salt only until the funnel of the salt reservoir is full, so that itcan close properly. Do not add more than 2 kg of salt.

As the salt reservoir is being filled, displaced water (saline solution)may run out.

Clean any excess salt from the area around the salt reservoir andespecially from the seal. Do not use running water as this cancause the salt reservoir to overflow.

Close the funnel.

Run the Rinsing programme after refilling salt.

This will ensure that any traces of salt and saline solution aredissolved and rinsed away.

Salt and saline solution which has overflowed can cause corrosiondamage if they are not rinsed away.

Test point formeasuring waterpressure

On mobile units and baskets with spray arms and additional injectorbars or other wash connections, there is a connection on the injectorbar or a wash connection for water pressure measurement. The exactlocation is described in the respective operating instructions for themobile units / baskets.

On mobile units and baskets with spray arms and no additional washconnections, access for the wash pressure measurement is providedon the side of the water supply pipe.

To measure water pressure, replace the blind stopper with a LuerLock adapter, e.g. E 447.

Under no circumstances may items to be washed, washingattachments etc. be connected to the test point. After themeasurement, the test point must be closed again with the blindstopper.


39

Preparing the load

Only items which have been declared by their manufacturer assuitable for machine reprocessing may be processed. Themanufacturer's specific reprocessing instructions must beobserved. Processing of disposable items is not allowed.

Special injector nozzles, irrigation sleeves or adapters may berequired for appropriate internal cleaning, depending on the load.These, together with other accessories, are available from Miele.

Protective measures for personal safety must be observed.Wear protective gloves when handling contaminated loads or useappropriate tools, e.g. tweezers.

– Arrange the load so that water can access all surfaces. Thisensures that it gets properly cleaned.

– Do not place items to be cleaned inside other pieces where theymay be concealed. Do not place items so close together thatcleaning is hampered.

– Hollow items must be thoroughly cleaned, internally and externally.

– Ensure that items with long narrow hollow sections can be flushedthrough properly before placing them in a fitting or whenconnecting them to a water connection.

– Hollow containers should be inverted and placed in the correctmobile units, baskets, modules and inserts, to ensure that watercan flow in and out of them unrestricted.

– Deep-sided items, e.g. trays, should be placed at an angle to makesure water runs off them freely.

– Take apart any items which can be dismantled according to themanufacturer's instructions and process the individual partsseparately from each other.

– Lightweight items should be secured with a cover net (e.g. a A 6 orA 810) and small items placed in a mesh tray to prevent them fromblocking the spray arms.

– The spray arms must not be blocked by items which are too tall orwhich hang down in their path.

– Broken glass can result in serious injury when loading or unloading.Broken glass items must not be processed in the machine.

– Nickel and chrome-plated items, and items made of aluminium,require special procedures and are not generally suitable formachine reprocessing. They require special processing conditions.

– It is advisable to use only instruments made of special applicationsteel which are not susceptible to corrosion.


40

– Only reprocess small items and micro components in specialinserts, mesh trays with lids or mesh inserts.

– Heat-sensitive items must only be reprocessed using a chemo-thermal programme.

For validation purposes it is essential to follow the loadinginstructions given on the template.

Observe the further information given in the following sections asnecessary depending on area of application.

Preparing theload

Empty the load before sorting

Ensure that no acid or solvent residues, especially hydrochloricacid or chlorides, get inside the wash cabinet.

Dismantle the items for washing where possible according to themanufacturer's instructions and open any valves or taps.

Follow the instructions of the manufacturer regarding pre-cleaningand pre-treatment as necessary.

Thoroughly rinse items which have been pre-treated with chemicals(see "Wet loading")

Dry loading Contaminated medical products should be placed directly intobaskets and inserts in the washer-disinfector after use without pre-treatment

Dry loading is preferable for contaminated medical items.

Wet loading Chemically pre-treated items must be rinsed thoroughly by hand orusing the Rinsing programme before reprocessing in the washer-disinfector to avoid a significant build-up of foam.


41

Carry out a visual check before starting every programme:

– Is everything correctly loaded/connected for cleaning?

– Was the recommended loading template followed?

– Can the lumen / narrow sections of hollow items be accessed bythe wash fluid?

– Are the spray arms clean and do they rotate freely?

– Are the filters clean? Remove any coarse soiling and clean them if necessary.

– Are the removable modules, injector nozzles, irrigation sleeves andother rinsing fittings securely connected?

– Are the baskets and modules or mobile units correctly connected tothe water supply and are the water connectors undamaged?

– Are all chemical containers sufficiently filled?

The following must be checked at the end of every programme:

– Carry out a visual check of the load for cleanliness.

– Check that all hollow items are still securely located on their injectornozzles.

Any hollow items that have become disconnected from theirfittings during reprocessing must be reprocessed.

– Check that the lumen of hollow items are free of obstruction.

– Check that injector nozzles and connectors are securely held inposition in the baskets or inserts.

Recontamination Take appropriate measures to prevent recontamination of processeditems, e.g.:

Wear clean gloves when removing the wash load.

Remove the entire wash load from the carriers before reloadingthem.

Protein test Cleaning results should be subjected to periodic protein tests, e.g.weekly with the Miele test kit or the Miele ProCare Protein Check(Depending on country, not available in all countries).


42

Surgical instruments (OP)The duration between using instruments and reprocessing themshould be kept as short as possible, and must not exceed 6 hours.

Surgical instruments including those used in minimally invasivesurgery should be thermally disinfected. Fully demineralised watershould be used for the final rinse whenever possible to ensure nomarks are left on the load and to avoid corrosion. If the water usedcontains more than 100 mg chloride/litre there is a risk of corrosion.

Hinged instruments should be opened up and placed in mesh trays.They must not cover each other.

To avoid injury from instruments with upward-facing probes, thewasher-disinfector should be loaded from rear to front, andunloaded from front to rear.

Instruments should be dismantled in accordance with theirmanufacturer's instructions and any caps or seals removed and tapsopened to ensure that suds solution can access lumen and hollowsections.

Instruments with narrow lumen must be manually pre-rinsed wherenecessary. Follow the instrument manufacturer's instructions onhow to handle them.

Rigid fibre optics To avoid mechanical damage only process rigid fibre optics ininserts made by the rigid fibre optic manufacturer or in a specialinsert such as the E 460.


43

Operating theatre shoes

Theatre shoes should be cleaned and disinfected in a machineinstalled specifically for this purpose only. This is to ensure, forexample, that any fluff or soiling cannot settle inside the lumen ofhollow instruments.Theatre shoes can only be reprocessed together with other items ifa risk assessment has been carried out by the user.

Heat-sensitive theatre shoes and insoles should be cleaned andchemo-thermally disinfected at 60 °C. A special programme has to beuploaded by Miele Service, and an additional dispensing system fordispensing chemical disinfectant must be retrofitted. To establish the effectiveness of chemical disinfection agents fordisinfection please consult the manufacturer of the chemical agent.

A thermal disinfection programme Theatre shoes can be used as longas the manufacturer has confirmed that the theatre shoes are thermo-stable to 80 °C.

Remove insoles before reprocessing theatre shoes.

Please equip the upper and lower carriers with the following insertsfor reprocessing theatre shoes:

– A 151 with A 307 insert for theatre shoes up to size 48 (Eur).

– A 101 with A 308 insert for insoles up to size 45 (Eur).

A large amount of fluff can build up in the machine when cleaningtheatre shoes. The filters in the wash cabinet should therefore bechecked regularly, and cleaned when necessary. See "Cleaningand care".


44

Ophthalmology

Ophthalmic instruments should only by reprocessed in awasher-disinfector specifically dedicated for this application.This way there is no risk of residues from other disciplines beingdeposited in narrow lumened hollow instruments.Synthetic cover nets, e.g. Miele A2 or A3 cover nets, must not beused in this washer-disinfector.

When reprocessing ophthalmic instruments do not dispenserinsing agent.

Ophthalmological instruments should only be reprocessed in mobileinjector units designed for them.

Baby bottles can be cleaned and disinfected in containers e.g. the E 135 and teats in special inserts e.g. the E 364 for wide necked teatsand the E 458 for screw cap teats.

– Highly alkaline cleaning agents can etch and erase the graduatedmarkings on baby bottles. Please only use baby bottles withdishwasher-proof level markings.

– If there is a delay of 4 hours or more before bottles can beprocessed, fill them with water to prevent residues from drying on.

If the process is not to be followed by sterilisation, the load shouldbe dried completely before storage to avoid the development ofwater-borne bacteria.An adequate drying time must be selected to ensure this and thedrying result must be checked at the end of every programme.

Containers and inserts for baby bottles and teats are supplied withtheir own operating instructions.

Chemical processes and technology

49

In this section you will find a description of the causes of common chemical reactionswhich can occur between different types of soiling, chemical agents and the componentsof the machine, along with their remedies as necessary.

This section is intended as a guide. If unforeseen interactions occur during reprocessing,or if you have any queries on this subject, please seek advice from Miele.

General notes

Problem How to resolve it

If elastomers (hoses and seals) and plasticsin the machine are damaged, for exampleby swelling, shrinking, hardening orbrittleness of materials, tears and cracks,components will not function correctly andthis generally leads to leaks.

– Establish the cause of the damage andrectify it.

See information regarding "Chemicalagents", "Soiling" and "Reaction betweenchemical agents and soiling".

Heavy foaming during a programme affectscleaning and rinsing results. Foam escapingfrom the wash cabinet can cause damageto the washer-disinfector. Cleaning processes cannot be regulatedand validated where there has been a build-up of foam.

– Establish the cause of the foam andrectify it.

– Check the process used regularly tomonitor foaming levels.


Corrosion to stainless steel in the washcabinet and to accessories can give them adifferent appearance:

– rust (red marks / discolouration),

– black marks / discolouration,

– white marks / discolouration (etchedsurface).

Corrosive pitting can lead to the washer-disinfector not being water-tight. Dependingon application corrosion can influencecleaning and rinsing results or causecorrosion to stainless steel items in thecabinet.

– Establish the cause of the corrosion andrectify it.



50

Chemical agents


The ingredients in chemical agents have astrong influence on the longevity andfunctionality (throughput) of the dispensingsystem.

– Follow the chemical agent manufacturer'sinstructions and recommendations.

– Carry out a regular visual check of thedispensing system (siphons, hoses,dispensing containers etc.) for anydamage.

– Regularly check the flow rate of thedispensing system.

– Ensure that the regular cycle ofmaintenance is observed.

– Please contact Miele Service for advice.

Chemical agents can damage elastomersand plastics in the machine andaccessories.

– Follow the chemical agent manufacturer'sinstructions and recommendations.

– Carry out a regular visual check of anyaccessible elastomers and plastics fordamage.

The following chemical agents can causelarge amounts of foam to build up:

– Cleaning agents and rinsing agentscontaining tensides.

Foam can occur:

– in the programme block in which thechemical agent is dispensed,

– in the following programme block if it hasbeen spilt,

– in the following programme with rinsingagent if it has been spilt.

– Process parameters in the washprogramme, such as dispensingtemperature, dosage concentration etc.must be set to ensure the whole processis foam free or very low foaming.

– Please observe chemical agentmanufacturer's instructions.

De-foaming agents, especially siliconebased ones can cause the following:

– deposits to build up in the cabinet,

– deposits to build up on the load,

– elastomers and plastics in the washer-disinfector can be damaged,

– damage to certain plastics (e.g.polycarbonate and plexiglass) in the loadbeing processed.

– De-foaming agents should be used inexceptional cases only, for instance whenabsolutely essential for the process.

– The wash cabinet and accessories shouldbe periodically cleaned without a load andwithout de-foaming agent using theSpecial 93°C-10' programme.

– Please contact Miele Service for advice.


51

Soiling


The following substances can lead to aheavy build-up of foam during washing andrinsing:

– some disinfecting agents anddishwashing detergents,

– active foaming agents such as tensides.

– Thoroughly rinse items in waterbeforehand.

– Select a cleaning programme with at leastone short pre-rinse in cold or hot water.

The following substances cause corrosionto stainless steel in the wash cabinet onaccessories:

– hydrochloric acid,

– other substances containing chloridessuch as sodium chloride etc.,

– concentrated sulphuric acid,

– chromic acid,

– particles of iron and swarf.

– Thoroughly rinse items in waterbeforehand.

– Put the drip-dry items to be washed intothe mobile units, baskets, modules andinserts and start a programme as soon aspossible after placing in the washer-disinfector.

Reaction between chemical agents and soiling


Soiling containing high protein levels suchas blood can cause a heavy build-up offoam when processed with alkalinechemical agents.

– Select a cleaning programme with at leastone short pre-rinse in cold water.

Non-precious metals such as aluminium,magnesium and zinc can release hydrogenwhen processed with very acidic or alkalinechemical agents (oxyhydrogen reaction).

– Please observe chemical agentmanufacturer's instructions.
