4.1 Plumbingconnection

Watersupplyanddrainconnection
Thewaterpipelinesandelectricitysupplycableleadoutofthebottomright‐
handcorneroftheappliance.Connectthewaterintakehosetoaconnector
with¾”gasthreadedfitting,fittingthefilterAprovided(inmodelswith
aquastop,thefilterandring‐nutformasingleunit).
Theconnectiontothewatermainsmustonlybemadewithnewhoses;the
useofoldorwornhosesisnotpermitted.
Thedynamicwatersupplypressuremustbebetween1and6bar;ifitishigherapressurereducer
mustbeinstalled.
Itisessentialtofitamainstoptaponthewaterintakedeliverpipeline;thetapmustbeaccessible
afterinstallationoftheappliance,sodonotinstallitbehindthewarewasher.Thestatedcycle
durationappliestoappliancessuppliedwithhotwater>50°C<60°CIfthewarewasherissupplied
withcoldwater,thecycledurationmightincreasedependingontheintakewatertemperature.


Caution:theindoorsystemandpremisesinwhichequipmentforinstitutionsisinstalled
mustcomplywiththerelevantregulations.
Themanufacturerdeclinesallliabilityfordirectorindirectinjuryordamagederivingfromfailure
tocomplywiththeseregulations.
Beforeinstallation,checkthattherearenoobjectsormaterialsinthevicinitywhichmaybe
damagedbysteamorsplashesofwashingsolution,orthatanysuchitemsaresuitablyprotected.
Placethewarewasherinthechosenpointandremovetheprotectivefilm.
Levelthewarewasher(withtheaidofaspiritlevel)onitsadjustablefeettoensurethatitis
stable;allothermountingsolutionsmustbeapprovedbythemanufacturer.

Refertotheconnectiondiagramforthemaximumpermittedheightofwalldrains–(seeTECHNICAL
DATA)


Caution:makesurethattheintakeanddrainhosesarenotbent,constrictedorcrushed
afterinstallation.

Wheninstallingthedrainhosetoasiphonwithvalve,themaximumheightofthedrainoutletis
reducedto600mm.
4.2 Electricalconnection


Thewarewasherandanyadditionalequipmentmustbeconnectedtotheelectrical
systembyauthorised,skilledstaff,inaccordancewiththerelevantregulations;also
complywiththetechnicalinstructionsfortheconnection.
Thetotalratedpowerisstatedontheappliance’stechnicaldataplate.
Theelectricalprotectiondevicesfittedforthewarewashermustservethisappliance
only.
Theusermusthaveamasterswitchandadifferentialsafetybreaker,withrating
suitablefortheappliance’scharacteristics,installedontheelectricitysupplylinein
accordancewiththerelevantregulations.
Theseswitchesmustbeinstalledclosetothewarewasher,beeasilyaccessibleafter
installation,andprovidecompletedisconnectionfromtheelectricalmainsin
overvoltageclassIIIconditions.

Warning!!!
Thewarewasherisalwayspoweredupunlessthemasterswitchisturnedoff.

Connecttheappliancetotheuser’searthsystem.Theterminalfortheconnectionis
inthebottomright‐handcorneroftheappliance.
Theearthwire(PE)isyellow‐greenincolour,theneutralwire(N)isblueandthelive
wires(L1,L2,L3)areblack,greyandbrown.
Intheeventofsingle‐phaseconnection(230V‐1N~),theconnectiontotheelectrical
mainsmustbemadeusingacablewithplugcompliantwiththerelevantregulations.


Firststart‐up
Theelectricalprotectionsystemmustundergoafunctionaltestbeforetheapplianceisputinto
operation.
Theappliancemustbeinstalledand/orinspectedbyqualifiedstaff,whowillstartitupforthefirst
timeandprovidetherelevantoperatinginstructions.


Preparingforuse(important)
Therinseaiddispenserisfittedonallmodels,thedetergentdispenseronlyonsome.
Ifbothdispensersarepresentputtheexternaldetergentandrinseaidcontainersinplaceand
inserttherespectiveintakehosesontherearoftheapplianceintothem.
Redhose:detergent
bluehose:rinseaid



Beforeinsertingthehosesintothecontainers,fittheweights(needed
toensurethattheyalwaysdrawinliquidfromthebottomsofthe
containers)andthefiltersontotheirendsasshown.
Ifthedetergentdispenserisnotfactory‐fitted,itcanberetrofitted
afterorderingtherelativekit.



Asanalternativeanexternaldispensercanbefitted,makingtheelectricalconnectionbymeansof
anH05RN‐F2x0.5mmelectricalcable,whichcanbelaidalongtherouteshownintheTECHNICAL
DATAdiagramandconnectedasshowninthewiringdiagramsuppliedwiththewarewasher.
Thedispensermustoperateon230V/50Hzwithmaximumpowerabsorptionof15W.
Connecttothedetergentdispenseroutsidethewarewasherusingtheredhosementionedabove.

4.3 Usingthewatersoftener(onmodelswiththisfeatureonly)


Thequantityoflimeinthewater(whichindicatesitshardness)causeswhite
marksondrydishesanddishesalsotendtolosetheirshineovertime.
Thewarewasherisequippedwithanautomaticwatersoftenerwhichremoves
thesubstancesthatcausehardnessfromthewaterwiththeaidofregenerating
salt.







NW511

14


Thefirsttimethewarewasherisused,alitreofwatermustbepouredintothe
tankwiththesalt.
Wheneverthetankisfilled,alwaystakecaretoensurethatthecapisfirmly
closed.
Themixtureofwateranddetergentmustnotgetintothesalttank,asthiswould
impairoperationoftheregenerationsystem.
Inthiscasewarrantycoverwillbeforfeited.





IMPORTANT: 

Wheneverthetypeofdetergentorrinseaidischanged,itisABSOLUTELYESSENTIALtoflushout
theperistalticpumpsbyplacingtheexternalintakepipesinwaterforafewcycles.

Alwaysuseonlyproductsspecificallyrecommendedforuseinawarewasher.

Failuretocomplywiththisrecommendationleadstoforfeitureofthewarrantyentitlementon
theappliance’swatersystem.

TheinternalpipesofthedetergentandrinseaidpumpsshouldbereplacedbytheAfter‐Sales
Serviceevery12monthsor15,000washcyclesandoperationofthediaphragmrinseaidpump
shouldbechecked.

5 SET-UP



Aseriesofoperationscanbecarriedoutwhenthewarewasherisfirstinstalledtocustomiseittothe
user'srequirements.Tomodifytheparameters,proceedasfollows.
5.1 DisplayContents

Thetwogreendigitsprovidethefollowinginformation:


5.2 Noteondisplayoftemperatures
BoththeBoilerandtheTanktemperaturesprovideinstantaneousreadingsofthecurrentvaluepicked
upbytheprobe,butduetothethermalinertiaoftheprobeoritsseat,waitabout1minuteafterthe
heatingelementpowerabsorptionreadingtoobtaintherealtemperature.
5.3 Parameterprogrammingprocedure
Toaccesstheprogrammingmenu,proceedasfollows:
1) switchtheapplianceoffwiththe(OnOff)key
2) Within6seconds,presskeyP1(SHORTwash)7times.Waitforthe6secondstopass;attheend
P0appearsonthedisplay
3) UsekeyP1toselecttheparametertobemodified
4) PressthePUMP‐OUTKEYtodisplaytheparameterformodification
5) ModifytheparameterbypressingkeyP1
6) ConfirmthechangebypressingthePUMP‐OUTkey
7) Selecttheotherparametersformodificationinthesamewayandproceedasdescribedabove
8) Aftersettingalltheapplianceparameters,presstheOnOffkeytoquit.
