Vacuum Sensor System Installation Guide Field Wiring Vac System Connections <br /> Field ging Vac System Connections <br /> 1. Tie wrap the loose cable pairs into a bundle going from the Vac Sensor housing to the sump junction box(es). <br /> 2. Get necessary cord grip bushings from the kits-one for each Vac Sensor,Vac Float, and the Tank interstitial <br /> sensor cable that will enter the junction box(es) in the sump. Loosen the cord grips and screw each one into a <br /> junction box port. <br /> 3. Push the first Vac SensorNac Float cable pair into adjacent cord grips (keep the pairs together as the two <br /> cables will typically be wired to one cable going to the TLS Console).Make sure all of the cables to the <br /> console are tagged (e.g.,Tank 1 product line,Tank 1 vapor line) to facilitate TLS setup. <br /> 4. Strip back the leads of one of the cables from the TLS Console 3/8".Strip back the leads of the Vac Sensor/ <br /> Vac Float pairs 3/8". Using wire nuts from the kits attach the wires as per the diagram in Figure 15. NOTE:the <br /> Vac Sensor cable has three wires and the Vac Float cable has two wires. <br /> 5. Seal wire nuts with epoxy sealant following the instructions in Figure 16. Note:the illustration shows only two <br /> cables in the pack, but in this case, all three cables must be submerged as per the illustration. <br /> 6. Connect the remaining Vac Sensor/Vac Float pairs and the Vac Sensor/Tank Float pair as discussed above, <br /> sealing each set of wires in epoxy sealant packs. <br /> ® O <br /> CAUTION:Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause allergic skin reaction. <br /> Contains:epoxy resin and Cycloaliphatic epoxycarboxylate. Precautions:Wear suitable protective clothing, <br /> gloves,eye,and face protection. Use only in well ventilated areas.Wash thoroughly before eating,drinking,or- <br /> smoking. <br /> Epoxy sealant pak <br /> Vac y Wire nut(3) <br /> Sensor ,------- -, <br /> White White (+) <br /> Black To Smart Sensor <br /> Red ' <br /> Black(-) Interface Module <br /> Red <br /> Black <br /> -------------- <br /> Vac Float or vacsensorslfigl&eps <br /> Interstitial Sensor <br /> Figure 15.
