
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

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dishwasher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dishwasher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dishwasher,beeasilyaccessibleafter
installation,andprovidecompletedisconnectionfromtheelectricalmainsin
overvoltageclassIIIconditions.

Warning!!!
Thedishwasher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

5 FIRST START-UP

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dishwasher.
Thedispensermustoperateon230V/50Hzwithmaximumpowerabsorptionof15W.
Connecttothedetergentdispenseroutsidethedishwasherusingtheredhosementionedabove.
5.1 Usingthewatersoftener(onmodelswiththisfeatureonly)

Thequantityoflimeinthewater(whichindicatesitshardness)causeswhitish
marksondrydishesanddishesalsotendtolosetheirshineovertime.
Thedishwasherisequippedwithanautomaticwatersoftenerwhichremoves
thesubstancesthatcausehardnessfromthewaterwiththeaidofregenerating
salt.



Thefirsttimethedishwasher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dishwasher.

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.

6 SET-UP



Aseriesofoperationscanbecarriedoutwhenthedishwasherisfirstinstalledtocustomiseittothe
user'srequirements.Tomodifytheparameters,proceedasfollows.
6.1 DisplayContents


elementswitchesoff
toobtaintherealtemperature.
6.3 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.
