2 Vac Sensor Installation Attaching Vac Sensor Cables and Tagging Vac SensorNac Float Pairs <br /> Attaching Vac Sensor Cables and Tagging Vac Sensor/Vac Float Pairs <br /> 1 . Next get the Vac Sensor cables (with connectors on one end) from the kit (s) and attach the connector of each <br /> cable to each of the Vac Sensor ports labeled TLS (on the Vac Sensor cover) . Uncoil each of the Vac Float <br /> cables . Notice that each Vac Sensor, except the one for the tank interstice, has a short piece of tubing <br /> connecting it to a Vac Float beneath it ( Figure 2-8) . A Vac Sensor/Vac Float tubing connected pair must be <br /> wired together in the junction box. <br /> 2 . Use a felt pen and write on the top of the Vac Sensor housing to what device each of the Vac Sensors below <br /> will be attached (see Figure 2-9) . For example, P = product line, S = containment sump interstice, V = vapor <br /> line , and T = tank interstice. NOTE: If the mark you wrote on the housing over the first Vac Sensor was <br /> locate the cable ends of this Vac Sensor/Vac Float pair, tape them together about every foot along their length <br /> and at their ends , and tag the end of this cable pair ' P' or ' Product Line Vac Sensor' . Repeat this taping and <br /> tagging for each of the Vac Sensor/Vac Float pairs. The Vac Sensor marked 'T' will only have one cable, so tag <br /> the end of this cable 'T' for 'Tank Vac Sensor'. <br /> Product Vapor Tank Sump <br /> line line <br /> Vacuum <br /> I I I <br /> input from <br /> STP <br /> I <br /> I ® I <br /> 1 <br /> • I <br /> Figure 2-8: Identifying Vac Sensor/Vac Float Pairs <br /> Installing Vac Sensor Housing onto Support Bracket <br /> Route all of the cables through the opening in the mounting bracket and attach the Vac Sensor housing to the <br /> bracket by pushing the four hooks on the rear of the housing into the four slots in the bracket (see Figure 2-9) <br /> 2-6 <br />
