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.


Failuretocomplywiththisrecommendationleadstoforfeitureofthewarrantyentitlementon


TheinternalpipesofthedetergentandrinseaidpumpsshouldbereplacedbytheAfter‐Sales
