


Theappliance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glasswashermustservethisappliance

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


‐NWG410 ‐

12


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glasswasher.
Thedispensermustoperateon230V/50Hzwithmaximumpowerabsorptionof15W.
Connecttothedetergentdispenseroutsidetheglasswasher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white
marksondrydishesanddishesalsotendtolosetheirshineovertime.
Theglasswasher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glasswasher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glasswasher.

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.




Aseriesofoperationscanbecarriedoutwhentheglasswasherisfirstinstalledtocustomiseittothe
user'srequirements.Tomodifytheparameters,proceedasfollows.

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

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.



Useonlydetergentsandrinseaidsforindustrialglasswashers.
Donotusedetergentsintendedforhandwashing.
WerecommendtheuseofNelsonproducts,speciallydevelopedforthisglasswasher.

Whentoppingupthedetergentandrinse‐aidcontainers,takecarenottoswapthe
products;thismightdamagetheglasswasherandcausemalfunctions.

Donotmixdifferentdetergents;thiswoulddamagethedispenserdevice.Failuretocomplywiththis
recommendationleadstoforfeitureofthewarrantyentitlementontheappliance’swatersystem.
Industrialglasswasherdetergentsmaycauseseriousirritation.Complycarefullywiththeinstructions
providedbythedetergentproduceronthepack.
