4 INSTALLATION INSTRUCTIONS FOR THE AFTER-
SALES SERVICE
4.1 Plumbinghookup

Watersupplyanddrainhookup
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 Aprovided.
The connection to the water mains must only be made with new hoses; the use
of old or worn hoses is not permitted.
FOR MODELS WITH WATER SOFTENER:
An `approved` double check valve or some other no less effective device
providing backflow prevention protection to at least fluid category three
shall be fitted at the point of connection between the water supply and the
fitting or appliance.
FOR MODELS WITHOUT WATER SOFTENER:
An `approved` single check valve or some other no less effective device
providing backflow prevention protection to at least fluid category two
shall be fitted at the point of connection between the water supply and the
fitting or appliance.

Thedynamicwatersupplypressuremustbebetween1and6bar;ifitishigher,installationofa
pressurereducerisnecessary.
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dishwasher.Thestatedcycle
durationappliestoappliancessuppliedwithhotwater>50°C<60°C.Ifthedishwasherissupplied
withcoldwater,thecycledurationmightincreasedependingontheintakewatertemperature.The
dishwasherisfittedwithadrainpumpandcanoperatewithdrainconnectionsonthefloororwall.

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dishwasherinthechosenpointandremovetheprotectivefilm.
Levelthedishwasher(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.


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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
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.


THEPOWERSUPPLYCABLEMUSTBEREPLACEDBYTHEMANUFACTURERORAN

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.


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
