2 Safety Information
Pleaserememberthatdualcomponentsystemsworkwithextremelyhighpres-
suresandmaycauselifethreateninginjuriesifusedinappropriately.
Alwayspayattentiontoandfollowallnotesintheusermanualsfortheoptionally
offeredaccessoryequipment.Payparticularattentiontothechapteronsafety
notesforthecorrespondingcomponents.
Please comply with the following instructions:
➤Neverpointthespraygunatyourself,otherpersonsorotherlivingbeings!
➤Neverholdyourngersorhandinfrontofthespraygunandneverreachinto
thejetspray.
➤Materialhosesmustbeabletowithstandpressuresbeyondthemaximum
workingpressure.
➤Materialhosesmustneverberepaired!
➤Nevertrytosealleakagesonconnectionsandhighpressurehosesbyhand
orbywrappingfabricaroundthem.Incaseofleakagesimmediatelydepres-
surizetheentiresystem(spraygun,hose,pump,etc.).Defectivepartsmust
bereplaced.
➤Securethespraygun(s)eachtimeworkisinterrupted,evenforshortbreaks,
andcheckthatitisproperlysecured,(Figure 2.1).
➤Switchoffthemachinebeforestartingmaintenanceandcleaningworkonthe
unitandthesprayingaccessories,(Figure 2.2).
➤Incaseofmaterialcongestionoragglomerationofmaterialinthespraying
system,residualpressurescanstillbepresentdespitepressuredischarge.
Payfullattentiontothiswhenperformingrepairwork!
➤Materialhosesandsprayguninparticularmustbedisassembledwithgreat-
estcaretoavoidaccidentscausedbyreleasedresidualpressures.
➤Whendisconnectingmaterialhoseswerecommendtocoverthescrewtting
withaclothtocatchanyescapingmaterialsprays.

SafetyInformation
➤Inclosedroomsorwithpressurizedsystems,inwhichaluminiumcomponents
orgalvanizedpartshavecontactwiththesolvent,hazardouschemicalreac-
tionsmayoccurwhenusing1.1.1-trichloroethane(TCE),methylenechloride
orothersolventscontainingchlorinatedhydrocarbons(CFCs).Ifyouwish
tousetheaforementionedsolventsorvarnishesandpaintscontainingsuch
solvents,weadviseyoutoconsultthe -customerserviceor
directly.
➤Wewouldliketopointoutthatwehaveaseriesofdualcomponentsys-
temsinrustandacidproofdesignavailableforsuchmaterials.
➤DANGEROFBURNING!
Dependingonthesettemperature,theoutersurfaceoftheadaptercanheat
upconsiderably.Youshouldthereforealwayswearprotectivegloveswhen
havingtoworkontheadapter!
➤Changingthemixingratiomaycauseachangeinpressureratioandthus
requiretheadaptationofthemax.permissibleairinletpressure.Inthiscase
theexistingsafetyvalvemustbereplaced.Consultationwith is highly
recommended.
➤Thesystemshouldneverbeoperatedwithoutsafetyvalve!
Ifthesafetyvalveneedstobereplaced,youcanndthecorrespondingorder
numberonthemachinecard.
➤Themaximumoperatingpressurespeciedbyusmustgenerallybeadhered
to for all parts(e.g.pump,heater,hoses,spraygun,safetyvalve).
Atvaryingoperatingpressuresthelowestvalueisalwaysvalidasthemaximum
admissibleoperatingpressurefortheentiresystem.
➤Generalexample:
Pump upto250bar/3625psi
Materialhose upto600bar/8700psi
Spraygun upto240bar/3480psi
Themaximumpermissibleoperatingpressurefortheentiresysteminthisexam-
pleis240bar.
➤Whenusinginatmospherescontainingsolventsthereisthedangerthatthe
powercablecouldbecomeawedorporous.
➤Thereforethepowercablemustbecheckedforexternallyvisibledamage
beforeeachstart-up.
➤Neverrepairapowercable.Damagedpowercablesmustalwaysbecom-
pletelyreplaced.
➤Thisworkmustbecarriedoutbyaprofessionalelectrician.

➤Alwaysuseopencontainers.Standthecontainersonagroundedsurface.
Whenusingmetalcontainersavoidcontactbetweenspraygunandcontainer
wall,becauseofpossibleelectrostaticcharging.
ThehighowvelocitiesassociatedwiththeAirlesssprayingmethodmay

ofthehosesmustbehigherthanorequalthemaximumoperatingpressureof
thecorrespondingdualcomponentsystem.
➤Switchoffallheaterswhenworkingwithcleaningagentsinthematerialcircuit
(e.g.completecleaning).
Completecleaningmustonlybeperformedafterthesystemhascooleddown.
➤The system must NOT be operated in explosion protection zones!
Sprayingequipmentdesignedwithoutexplosionprotectionmustnotbeusedin
workshopsthatcomeundertheexplosionprotectionordinance.
Juvenilesundertheageof16havenopermissiontooperatethisequipment.

3 Machine Description
The DUOMIXPU280ismostsuitablefortheapplicationofsolventfree
dual-componentplasticmaterials(polyurea).Thissystemenablestheseamless
andjointlessapplicationofcoatingsandlinings
Yourdualcomponentsystemwasdesignedtomeetyourspecialrequirements
(materialtobeapplied,mixingratio,transferquantity,etc.).
Exactmeteringofbothcomponentsisassuredbythexedmixingratio.Themix-
ingratiocanonlybechangedbyexchangingthematerialpumps.
Anyotheruseisdeemedtonotbeinaccordancewithregulations.
Themanufacturer'sapprovalmustbeobtainedbefore unitsareusedfor
anyotherpurposeorwithothermaterials,i.e.notinaccordancewiththeintended
use,otherwisethewarrantywillbecomenullandvoid.
Intendedusealsoincludescompliancewiththetechnicaldocumentationand
adherencetotheprescribedoperating,servicingandmaintenanceguidelines.
Unauthorizedconversionsoralterationsshouldnotbeundertakenonsafety
grounds.
Protectiveequipmentshouldnotbedismantled,convertedorbypassed.
Useofcomponentswhichhavenotbeenmanufacturedordeliveredby
rendersanywarrantynullandvoid.
Theunitshouldonlybeoperatedwithintheprescriptivelimitvaluesandmachine
parameters.
Iforiginalaccessoriesandsparesof WilhelmWagnerGmbH&Co.KG
areused,usabilitywithourunitsisguaranteed.Itis,however,mandatoryto
respectthesafetyregulationsoftheaccessoriesandspareparts.Thesesafety
regulationsarefoundinthecorrespondingusermanualsfortheaccessories.
Ifforeignaccessoriesorsparepartsareused,thecompany cannotguar-
anteethesafetyoftheentiresystem.Similarlyliabilityisnullandvoidfordam-
agesorinjuriesincurredthroughuseofthoseaccessoriesandspareparts.
Dependingonwhichmaterialsareprocessed,hazardousfumesmaybegener-
ated.Forthispurpose,alwaysensureforsufcientaerationandventilationatthe
workplaceforavoidingdamagetoyourhealthandproperty.Youshouldalways
followtheprocessinginformationissuedbythematerialmanufacturers.
Thesoundpressurelevelofthisunitislessthan85db(A).
However,operatingpersonnelshouldstillbeprovidedwithsuitablenoiseprotec-
tionequipment.Theoperatorisresponsibleforadheringtonoiseandvibration
protectionregulations.Forthispurpose,payspecialattentiontotheconditionsof
thesettinguplocation,e.g.willthenoiseexposureincreaseifthesystemisset
upinoronhollowbodies.
