Water softenerIn order to achieve good cleaningresults, the washer-disinfector needs tooperate with soft water. Hard waterresults in the build-up of calciumdeposits on instruments etc. and in thewasher-disinfector.Mains water with a hardness levelhigher than 0.7 mmol/l (4° d – Germanscale) needs to be softened. This takesplace automatically in the integratedwater softener.– The water softener requiresreactivation salt.– The washer-disinfector must beprogrammed to correspond to thewater hardness in your area.– Your local water authority will be ableto advise you on the water hardnessin your area.Where the water hardness fluctuatese.g. between 1.4 - 3.1 mmol/l (8 - 17 °dGerman scale) always programme thewasher-disinfector to the higher value(3.1 mmol/l in this example).The built-in water softener hassettings from 1 °d - 60 °d (0.2 -10.8 mmol/l).In the event of a fault, it will help theservice technician if you know thehardness of your local water supply.16Enter the water hardness below:°d / mmol/lProgramming the watersoftener^ Switch off the machine.^ Turn the programme selector to f.^ Press ß and 6 at the same time,hold them in and, whilst doing so,switch the machine on with the I-0switch.The current programme status P.... willappear in the display.The indicator light p / 6 will come on.^ Press 0 once.E01 will appear in the display.^ Turn the programme selector oneswitch position clockwise (1 o'clockposition).The number 19 will appear in thedisplay (the factory water hardnessdefault setting in °d, equivalent to3.4 mmol/l).^ Press ß as many times asnecessary, or hold it in until therequired value (degree of hardnessin °d) appears in the display.See table on the next page for waterhardness settings in °d, mmol/l and °f.Once the number 60 has beenreached, the counter will begin again at0.^ Press 6.SP will appear in the display.^ Press 6 again.The setting will now be stored inmemory.

Water softenerFilling the salt reservoirOnly use special coarse grainedreactivation salt with granules ofapprox. 1-4mm.Donotuseothertypes of salt such as cooking salt,agricultural grade or gritting salt. Thesemay contain insoluble additives whichcan impair the functioning of the watersoftener. If in doubt consult the MieleProfessional Department.The salt reservoir holds approx. 2.5kg of salt.,Inadvertently filling the saltreservoir with cleaning agent willdamage the water softener.Before filling the salt reservoir makesure that you have picked up theright packet of reactivation salt.^ Remove the bottom basket from themachine.^ Unscrew the salt reservoir cap.Before filling the salt reservoir withreactivation salt for the first time, youmust fill it with approx. 2.5 litres ofwater to enable the salt to dissolve.Once the washer-disinfector hasbeen used, there is always sufficientwater in the reservoir.^ Place the funnel provided in position.^ Fill carefully with salt.As it is poured in, displaced water willrun out.^ Remove the funnel and wipe anyresidual salt off the screw threads onthe socket.^ Screw the cap back on firmly.^ Run the PRE-RINSE D programme toremove any traces of salt from thecabinet.The programme sequence may bedelayed for a few minutes after thestart of the PRE-RINSE Dprogramme. This is not a fault. Thewater softener is being reactivated.18

Water softenerAdd salt indicatorReactivation takes place automaticallyduring a programme.The programme sequence indicatorlight a k lights up whilst this ishappening.^ Add salt when the Add salt b kindicator lights up.19

Areas of applicationThis washer-disinfector normallyrequires a top and bottom basket.Various inserts and special baskets arealso available for a wide variety ofinstruments and utensils.Select baskets and inserts which areappropriate for the application.Notes on the individual areas ofapplication and examples of loadingare given on the following pages.Before starting a programme youshould carry out a visual check onthe following:– Is everything correctlyloaded/connected for cleaning?– Are the lumen or necks of hollowinstruments positioned so that watercan access them unhindered?– Are the spray arms clean and dothey rotate freely?– Are the filters clean? Remove anycoarse soiling and clean themproperly if necessary.– Is the adapter connecting the watersupply to the spray arms/jetscorrectly connected?– Are all chemical containers filledsufficiently?At the end of each programme:– Carry out a visual check of the loadfor cleanliness.– Carry out a protein test on a samplebatch of items, e.g. with the Mieletest kit.– Check that all hollow shaftedinstruments are still securely locatedon their jets.,Any hollow instruments that havebecome disconnected from theiradapters during processing must bere-processed.– Check that the lumen of hollowinstruments are free of obstruction.– Check that jets and connectors aresecurely held in position in thebaskets or inserts.20

Areas of applicationLoading the machine– Arrange the load so that water canaccess all surfaces. This ensuresthat they get properly cleaned.– Do not place items to be cleanedinside other pieces where they maybe concealed.– Hollow instruments must bethroughly cleaned, internally andexternally.– Hollow vessels should be invertedand placed in the correct basketsand inserts to ensure that water canflow in and out of them unrestricted.– Deep-sided items should be placedat an angle to make sure water runsoff them freely.– Tall, narrow, hollow items should beplaced in the centre of the baskets toensure better water coverage.– Mobile units or baskets with anadapter must engage correctly.– The spray arms must not be blockedby items which are too tall or whichhang down in their path.– It is advisable to use instrumentsmade of surgical steel only, as theseare not susceptible to corrosion.– Nickel plated instruments andcoloured anodised aluminiuminstruments are not suitable formachine processing.– Use the CHEM 60°C-5' andcombiCHEM 60°C-5' programme forinstruments which cannot withstandheat.– Disposable instruments must not beput into the machine for processing.Preparing the load^ Empty all containers before loadinginto the machine (paying particularattention to regulations regardinginfectious diseases and epidemics).,Ensure that acids and residualsolvents, especially hydrochloricacid or chlorides, do not get into thewash cabinet.Loading instrumentsContaminated instruments can beplaced directly in the machine withoutpre-treatment (no soaking required).21

Areas of applicationWater connection springadapterMake sure that the spring adapter forwater connection engages correctlywhen a basket or injector unit isinserted in the machine. It must be 4-5mm higher than the water connectioninlet in the machine.If it is not, adjust the adapteraccordingly.Height adjustable top basketThe top basket can be adjusted aboveand below the middle position by 2 cm.Different height items can beprocessed in this machine dependingon the position the top basket is set atand the inserts used.To adjust the top basket:^ Pull out the top basket until aresistance is felt; lift from the runnersand remove.^ Unscrew the roller bearings on bothsides of the basket with a 7mmspanner and reposition as required.^ Loosen lock ring a.^ Push up adaptor b.^ Tighten lock ring c.22

Areas of application(OP) Surgical instrumentsSurgical instruments should be storedfor as short a time as possible beforemachine processing.Disinfection of surgical instruments andof those used for minimally invasivesurgery should preferably take placethermally. De-mineralised water shouldbe used for the final rinse whenpossible to ensure no marks are left onthe load and to avoid corrosion. If thewater used contains more than 100 mgchloride/litre there is danger ofcorrosion.Open up hinged instruments and placethem in mesh trays so that they are nottouching each other.Operating theatre shoesPolyurethane operating theatre shoes,and/or insoles should be cleaned andchemo-thermally disinfected at 60 °C.These can only be thermally disinfectedif the manufacturer states that they aremade of a suitably heat-resistantmaterial.To establish the effectiveness ofchemical disinfecting agents forchemo-thermal disinfection, consult themanufacturer.Theatre shoes should be cleanedand disinfected in a machineinstalled specifically for thispurpose only.Use the following baskets:– O 167 for theatre shoes up to size40,– O 173 for theatre shoes up to size41, and– U 168/1 for theatre shoes up to size45 .Alternatively insert E 484 can be usedin a suitable bottom basket, e. g.U 874/2, together with holder E 487for shoes or E 489 for insoles.A large amount of fluff can build upin the machine when cleaningtheatre shoes. The filters in the washcabinet should be checked regularlyand cleaned when necessary. See"Maintenance, Cleaning the filters inthe wash cabinet".23

Areas of applicationENTE 417For ear funnels and ear and nasalspecula. Insert can be placed in the topor bottom basket.^ Load the specula opened to allow allsurfaces to be accessed.E 373For ENT instruments, e.g. ear funnels.Insert can be placed in the top basket.The thin chome plating on earfunnels can be very sensitive toneutralising agents.24

Areas of application,To minimise the risk of injuryfrom instruments that are sharp ateach end, and when arranginginstruments that have a probepointing upwards, instrumentsshould be loaded starting at theback and working forwards, andunloaded starting at the front andworking backwards.Top basket/injector unit O 177/1Left hand side of the basket: holder and28 jets in silicone holders for the directinjection of hollow instruments. Thisensures adequate cleaning anddisinfection both internally andexternally.Right hand side of the basket: free e.g.for E 337 insert for upright instruments.26

Areas of applicationEndoscopy,To minimise the risk of injuryfrom instruments that have a probepointing upwards, instrumentsshould be loaded starting at theback and working forwards, andunloaded starting at the front andworking backwards.There are 10 injector jets with springclamps for e.g. catheters or hoses onthe middle axis.Top basket/injector unit O 176Right hand side of the basket: 14holders for rigid endoscopicinstruments up to 50 cm long in total.To ensure that water can flow in and outof the hollow parts of instrumentsunrestricted, remove caps and seals,open valves and arrange according tothe manufacturer's instructions.The left hand side is left free for inserts,e.g. E 379.27

Areas of applicationOphthalmologyThe E 429 mobile injector unit isdesigned for the cleaning anddisinfecting of ophthalmic instruments.The top level is fitted with variousconnections for hollow instruments, e.g.rinsing and suction hand pieces, andcannulae.Instruments are secured to the hoseconnectors in the mobile injector unitusing the silicone holders andconnectors in the rack.The lower level of the mobile injectorunit is designed to take E 441/1 insertsor E 142 mesh trays for processingsolid instruments.,When the E 429 is used, thelower water supply to thewasher-disinfector has to bechanged in accordance with theguidelines in the operatinginstructions for the E 429.For this reason it is not possible touse the E 429 alternately with otherunits/baskets.,Plastic fibre cover nets must notbe used in washer-disinfectorswhich are used to process hollowophthalmic instruments with narrowlumen.The mobile injector unit forophthalmic instruments is suppliedwith its own operating instructions.28

Areas of applicationAnaesthetic instruments (AN)Anaesthetic instruments should bethermally disinfected using thevarioTD AN programme.If the process is not to be followedby sterilisation, the load should bedried completely to avoid thedevelopment of water-bornebacteria.A sufficient drying time is thereforeabsolutely essential.Baby bottlesBaby bottles should be thermallydisinfected using the varioTDprogramme.If the process is not to be followedby sterilisation, the load should bedried completely to avoid thedevelopment of water-bornebacteria.A sufficient drying time is thereforeabsolutely essential.The mobile injector unit foranaesthetic instruments is suppliedwith its own operating instructions.Containers for baby bottles andteats are supplied with their ownoperating instructions.29

Dispensing chemical agentsAdding rinsing agent^ Open the door fully.To dispense rinsing agent in the finalrinse, the DOS 2 programme blockhas to be activated by a Miele servicetechnician.The dispensing of rinsing agent shouldbe activated if deionised water is notused in the final rinse programmeblock.Rinsing agent is necessary to ensurewater does not cling and leave markson items, and to help items dry fasterafter they have been washed.Rinsing agent is poured into thestorage reservoir and the amount set isdispensed automatically.^ Undo the screw cap.The rinsing agent reservoir holdsapprox. 180 ml.,Only fill the rinsing agentreservoir with rinsing agentformulated for washer-disinfectors.Do not fill it with cleaning agent.This would damage the reservoir.^ Add rinsing agent until the levelindicator is dark (see arrow in theillustration). Use a funnel ifnecessary.^ Screw the cap back on.^ Mop up any spilt rinsing agent. Thisprevents over-foaming occurringduring the next programme.30
