Vac Sensor Assembly Dimensions Field Assembling Vac Sensor/Vac Float modules If you are field assembling the Vac SensorNac Floats into the Vac Sensor housing continue to Step 1.If you are installing the pre-assembled 2,3,or 4 Vac Sensor kit go to"Installing Vac Sensor Housing Support Bracket"on page 8. 1. Get the Vac Sensor modules and brackets from each of the secondary piping vacuum monitoring kits. If a tank interstice is being monitored,also get the Vac Sensor module and bracket from that kit. 2. Get the Vac Sensor housing from the mounting kit and attach each of the Vac Sensors(up to 4)to the top of the housing using #10 x 3/6"self-tapping screws as shown in Figure 3.Mount the Vac Sensors with the'STP Siphon' labeled port facing the front of the housing. 3. For Vac Sensors requiring Vac Floats,continue to Step 4. For the Vac Sensor monitoring the tank interstice skip to step. 4. Get the Vac Floats,support brackets,plastic valves and#10 x 1/2"self-tapping screws from the secondary piping vacuum monitoring kits. If you are not monitoring a tank interstice,there is a maximum of two left-hand Vac Sensor/Float mounting po- sitions and two right-hand Vac Sensor/Float mounting positions in the Vac Sensor Housing (Figure 3).If a tank interstice is being monitored,then one of the four Vac Sensors will have no Vac Float attached. 5. Get the plastic valves,barbed elbows,tapered bushings and cord grip nuts from the Vac Float kits.Insert bushings and screw cord grip nuts into the two ports of the Vac Float.Insert a valve into one port and a barbed elbow into the other port of each Vac Float.Orient elbow and valves in Vac Floats as shown in Figure 4 then tighten nuts to secure the fittings. 5
