SAFETYPRECAUTIONS StepThree

AboutthisManual:PLEASEREADTHEENTIREQUICKSTARTPRIORTOINSTALLINGORUSINGTHISPRODUCT.This manual includes information on the LVU2700 Series Ultrasonic Level Transmitter from OMEGAENGINEERING. Please refer to the part number located on the switch label to verify the exact modelconfiguration,whichyouhavepurchased.

Users Responsibility for Safety: OMEGA ENGINEERING manufactures a broad range of level sensingtechnologies.Whileeachof these sensors isdesigned tooperate inawidevarietyofapplications, it is theusersresponsibilitytoselectasensormodelthatisappropriatefortheapplication,installitproperly,performtests of the installed system, andmaintain all components. The failure to do so could result in propertydamageorseriousinjury.

ProperInstallationandHandling:Onlyprofessionalstaffshouldinstalland/orrepairthisproduct.Installthetransmitterwith the includedFKMgasketandneverovertighten thetransmitterwithin the fitting. Alwayscheckforleakspriortosystemstartup.

WiringandElectrical:Asupplyvoltageof12to28VDCisusedtopowertheLVU2700Series.Electricalwiringofthetransmittershouldbeperformedinaccordancewithallapplicablenational,state,andlocalcodes.

Material Compatibility: The enclosure is made of Polycarbonate (PC). The transducer is made ofPolyvinylideneFluoride(PVDF).Makesurethatthemodel,whichyouhaveselected,ischemicallycompatiblewiththeapplicationmedia.

Enclosure: Whilethetransmitterhousing isencapsulated,corrosionresistance&submersible,theLVU2700Series is not designed to be operationalwhen immersed. It should bemounted in such away that theenclosure and transducer do not come into contactwith the applicationmedia under normal operationalconditions.
