Operation
NooilingorotherlubricationisnecessarywithaDia‐Vac®pump.

Ifthegasstreamhasahighlevelofparticulatematter,afiltershouldbeinstalledbeforethepump.Ifthe
gasstreamhasahighlevelofliquidmatter,amembraneseparatorshouldbeinstalledbeforethepump.
Thisshouldbeusedinconjunctionwithbestpracticesforpumpinstallationincludingmountingthepump
headsothatthedischargeportfacestowardtheground.Keepinmindthatthepumpheadcanberotated
inanydirectiononthehousing.Thegaswillalwaysflowinthedirectionofthearrowsontopofthehead.

Theelevatedandextendedpumpsareforuseinhazardousareaswhereheatedheadscannotbeusedto
preventcondensationbuildupinthepump.Thesepumpsaredesignedtohaveheadorheadsmounted
inaheatedenclosuretopreventcondensationofvaporswithinthepumphead.Theplateofeitherof
thesepumpscanholdtheentireweightofthepump.

Thispumpcanbemountedinanyposition.Ifthehousingneedstoberotatedformountingpurposes,
thatcanbedoneattheADIfacility.

Donotstartthepumpagainstpressureorvacuum.Forapplicationsthatmuststartunderpressureor
vacuum,contactADIandasuitablemotorwillbeselected.

Runningampsarelistedonthenameplateofthemotor.Apumprunningatasubstantiallyhighercurrent
thanshownonthemotorplateindicatesaproblem,pleaseseesection“Troubleshooting”below.Please
notethatthecurrentdrawatthestartupofthepumpwillbethreetofourtimesthenormalrunning
amps.
