0.2 CAUTIONSFORINSTALLATION
0.2.1 READGENERALSAFETYINFORMATION0.0,WARNINGS0.1andCAUTIONS0.2,0.3&0.4
0.2.2 Theunitshouldonlybeinstalled/operatedbyacompetentperson;Acompetentpersonissomeone
whoistechnicallycompetentandfamiliarwithsafetypracticesandthehazardsinvolved.
0.2.3 Donotliftthepumpset(wheresupplied)bypipework.Liftthepumpsetbythecontainerpalletusinga
pallet/forkliftorcranebypassingstropsunderneaththeskidusingaspreaderbar.Failuretoutilise
thesefacilitieswillresultindamagetothepumpset.
0.2.4 Storeinadryplacetoavoiddampconditionsdeterioratingtheequipment.
0.2.5 Protectagainstdirt,damageandfrost.Itisabsolutelyessentialthatnoforeignmattersuchaspipe
threadswarf,weldingslag,gritorstonesareallowedtoentertheequipment.Debrisofthistypecan
causeseveredamagetothesensors,mechanicalseals,diaphragmsandimpeller.Frost/freezingwill
damagesensors,pumps/pipeworkandcontrolpanelcomponents.
0.2.6 Theequipmentisonlysuitableforinstallationinaclean,dustfreeindoorenvironment,withadequate
protectionfromheatandfrost,andsufficientventilationtoensurecoolingofthemotors(where
applicable).Ambientairtemperatureshouldbebetween5and40degreescentigrade,non‐
condensating.Operationoutsideoftheseconditionscouldseriouslydamagetheequipment.
0.2.7 Iftheequipmentweretobestoredortakenoutofserviceforaperiodoftime(e.g.1weekormore),
thenwewouldrecommenddrainingtheequipmentofallwater/liquid(withdueregardtoanylocal
regulations)topreventfrostdamagetocomponents.Whenrestartingisrequiredwewould
recommendcommissioningbyourauthorisedserviceagent.
0.2.8 Ensurethebase/foundation/plinth/walltowhichtheequipmentistobeattachedhassufficientmass
comparedtotheequipment,inordertoavoidnoise/vibrationtransmission.E.g.themassofthebase
shouldbeatleastfivetimesthemassoftheequipment.

0.2.9 Ensuretheelectricalsupplyisthecorrectvoltage,current,frequencyandtypefortheequipment
suppliedandthatsuitablecircuitprotectionequipmentisinstalledinthesupply.Incorrectelectrical
installationcouldbeanelectricshock/burns/firehazard.
0.2.10 Whenaccessingthecontrolpaneltomakeelectricalconnectionsadoptanti‐staticprocedurese.g.
wearanti‐staticearthedwristband,toavoidriskofdamagingthecontroller.

despatchedwith“Loose”vessel(s)forassemblyonsiteitisabsolutelyessentialthattheybeinstalled
asdetailedintheinstructionsusingthefittingsprovidedwhereappropriate.Failuretoobservethis
willnullifycompliancewiththePEDandmaypresentasafetyhazard.Yourwarrantymayalsobe
affected.
0.2.12 WhereHydraulicAccumulator(s)/ExpansionVessel(s)aresuppliedasalooseitem,theymustbe
installed/connectedcorrectlybeforeoperatingtheequipment,otherwiseseriousdamagefromover‐
pressure/pumpoverheatingcouldoccur.
0.2.13 Donotoperatethisequipment/pumpsetpriortocommissioning(section2.2)Thiscouldcause
irreparabledamagetosensors/equipment/pumpset/pipework/systemcomponents.
0.2.14 Isolatethesensors/equipment/pumpsetbeforepressuretestingsystem.Excesspressurecould
irreparablydamagethepressuretransducer,pressureswitches(wherefitted)andthediaphragmsof
pressurevessel/hydraulicaccumulators.
0.2.15 Whereapplicableitistheinstallers’responsibilitytoensuresubsequentpipeworketccanacceptthe

0.2.16 Whenchlorinationofthesystemiscarriedout,ensurethatanyresidualchlorineisremovedby
thoroughflushingasdetailedintheHSEapprovedcodeofpracticeL8,toavoiddamagingthe
sensors/equipment/pumpset.Thenormallevelofchlorinationisupto2partspermillion(ppm),but
shockdosingforsterilizationpurposes,at25‐50ppmfor24‐48hoursisacceptableaslongasall
chlorineisremovedoncetheprocessiscomplete.Chlorinationbeyondtheselimitscouldseriously
damagesensors/pumpsetcomponentsandWILLNOTbecoveredbythewarranty.
0.2.17 Theinstaller/userisresponsiblefortheinstallationofthecorrectearthingandprotectionaccordingto
