operatethedevice.Whenthesystemisswitchedoff,theambienttempera‐
tureattheplaceofinstallationmustnotbebelow+41°F.


SubstructureThecustomermustprovideasubstructurewithasufficientlyhighload‐
bearingcapacity.Fortheoperatingweightofthedeviceandthedynamic
bonusload,seethedimensionaldrawing.

StructuralanalysisTheload‐bearingcapacityofthesubstructuremustbesubjectedtoastruc‐
turalanalysisbeforethedeviceisinstalled.

LiftingthedeviceWhenliftingthedeviceoutofthetransportationpackaging,itmayonlybe
suspendedusingtheuppereyeboltsorcraneeyes.

AligningthedeviceThedevicemustbeinstalledinaverticalpositionthatenablesittoworkin
afault‐freemanner.Makesurethattheairinletandoutletportsareinthe
rightplace.

DeviceattachmentFollowingalignment,thedevicemustbeboltedtothesubstructure.

FloordrainageTheinstallation roomshouldhaveafloordrainagesystemtoallowescaping
watertodrainawaysafely.Theoperatormustcheckwhetherthewater
canbedirectedintothesewagesystem.

4.3. Electricalconnection
InstallationElectricalinstallationworkmayonlybecarriedoutbyaskilledelectrician

ElectricalprotectionThewirecross‐sectionsandswitching/monitoringdevicesmustbede‐
signedwithdueconsiderationofthestartuptypeandmaximumcurrent.
Thecustomermustensurethatanappropriatemotorprotectionrelayisin‐
stalled.
Inthecaseofthedirectactivationofthefan,themotordevelopsahigh
startingtorqueatahighstartingcurrent;thiscanbeupto5to8timesthe

Theexhaustairandreturnairflowscanbedistributedbymeansofaswitch
intheexhaustline.
4.7. Humidificationofair
FormationofcondensateTheexhaustairwillprobablyrequirehumidificationdependingonthetem‐
peratureandrelativehumidityoftheexhaustair.Youshouldassumehu‐
midificationoftheexhaustairofaround90%inthedevice.
Theairvolumeoftheworkroomshouldbeatleast¼oftheairquantityre‐
circulatedbythedeviceperhoursothatwhenthedeviceisworkingatfull
returnairlevel,excessivehumidificationoftheambientairalongwiththe
formationofcondensationdoesnotoccur.
Thispreventsarelativehumidityof75%beingexceeded.

Chapter5Commissioning

GeneralThefollowingtasksmustbecarriedoutbeforecommissioning:
Installthesuctionandexhaustline.
Installthefreshwatersupplyline.
Fillthedevicewithwateruptotheidlewaterlevel.
Addacorrosionprotectionagent.
Installtheswitchingsystem.
Connecttheelectricalconsumers.
Openhandvalve2onthevalveblock.

MainswitchThemainswitchmayonlybeswitchedonbythecommissioningpersonnel
duringthecommissioningprocedure.

ColdcommissioningColdcommissioningiscarriedoutinMANUALMODE.
•Checkthedirectionofrotationofthedrives.
•Checkthepowerconsumptionofthedrives.
•Checkthesettingvaluesofthemotorprotectionrelay.
•Carryoutafunctionaltestoftheindividualcomponents.
•Adjusttheductworksystem.Makesurethatthesuctionlevelsatthe
individualcollectionpointsareequal.
Makesurethattheflowspeedinhorizontalpipesectionsisaround60‐
65ft/s.
•Adjustthelevelregulatorinlinewiththeoperationalwaterlevel.
•Switchonthefan.
See"Fan".

CAUTION
Toomanystartupcyclesperhour
OurmotorsareinClassS1andaredesignedforcontinuousoperation.Too
manystart‐upcyclescancausethemotorwindingtooverheat.
Thereforewerecommendthatthefansnotbecycledon/offmorethantwo
timesperhour


CommissioningCommissioningiscarriedoutinAUTOMATICMODE.
•Startthedevice/system.
•Checkthefunctionofthelevelregulator.
•Checkthedevice/systemtoensureleak‐tightness.
•Checkthedevice/systemforwaterescapingfromtheairoutlet.

Chapter6Fan
6.1. Commissioning
Commissioningmayonlybecarriedoutbytrainedprofessionals.The
trainedprofessionalinquestionmustassurehim‐orherselfthatthefanis
inperfectworkingorder.Thecommissioningregulationsforelectricalma‐
chinesmustbeobserved.
•Checkthesafetydevices.
•Turnonthemainswitch.
•Switchonthefan.
Thefanmayonlybeswitchedononcetherelevantductworkhasbeen
connected.Thisensuresthatthereissufficientsystemresistanceduring
therun‐upphase.
•Whencommissioningthefanforthefirsttime,checkthedirectionof
rotationofthemotor.

CAUTION
Thefanmustturninthedirectionindicatedbythearrow.
Thedirectionofrotationcanbecheckedusingafieldofrotationtester.

•Checkthepowerconsumption.Thepermittedpowerconsumptionof
themotormustnotbeexceeded.
6.2. Shutdown
•Switchoffthefan.
•Turnthemainswitchtothe"OFF"positionandsecuresothatitcannot
beturnedbackonbyanunauthorizedperson.
6.3. Startupbehavioroffans
Theremustbeasufficientaccelerationtorqueovertheentirestartuprange
uptothenominalspeedtoenabletherun‐upofthefan.Thisisnotalways
thecaseformedium‐andhigh‐pressurefans.Insuchcases,thefancanbe
runupagainstaclosedthrottledevice.
Powersupplyunits,switchingdevices,monitoringdevices(ifpresent),and
cablecross‐sectionsmustbedimensionedandcheckedbythecustomer
withregardtotheirstartuptypeandtimeandtheircurrentpeaks.
6.4. Startupfordirectactivation
Inthecaseofthedirectactivationofthefan,themotordevelopsahigh
torqueatahighstartingcurrent.
Thestartingcurrentduringthestartupphaseisbetween5and8timesthe
nominalcurrentdependingontheimpellerclass.
Thishighpowerconsumptionmustbetakenintoaccountwhenchoosing
thefuses.

Chapter7Operation

GeneralOnlyusethedevice/systeminAUTOMATICMODE!
Werecommendthatthedevice,ductworksystem,andwatersupplysys‐
tembesubjectedtoaregularvisualinspectionduringoperations.

WaterlevelWhenthedevice/systemisinuse,waterevaporatesconstantly.Thewater
levelmustthereforebecheckedregularly.Theautomaticrefillingofwater
shouldthentakeplace.
IfthelevelregulatorwasdeliveredbyCamfilAPC,pleaseobservethepro‐
videdoperatingmanual.

WatersupplyWhenthedevice/systemisinuse,thewatersupplyshouldbecheckedreg‐
ularly.

CAUTION
Malfunctionduetoclosedwatersupply
Ifthewatersupplyisswitchedoffduringoperations,thisresultsinawater
shortageinthecaseofamechanicallevelregulator.Thisisnotsignaled.
Asaresult,thedustseparationprocessissignificantlyreducedanddust
mayescapefromtheairoutlet.

SuctionperformanceWerecommendthatyouregularlycheckthesuctionperformanceanddust
collectionattheindividualcollectionpointsduringoperationsandkeepa
recordoftheresults.
