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

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.



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andthediaphragmrinseaidpumpshouldbechecked.

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.

Theeffectivetemperatureintheboilerwillbe5°CabovethesetP2


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.
