\ Installation Field Assembling Vac Sensor/Vac Float modules <br /> 6. Get the angled support brackets from each Vac Float kit. Depending on the Vac Float's position in the housing, <br /> orient the bracket so that when you slip the large hole in the front of the bracket over the valve handle,the two <br /> holes in the side of the bracket are in line with the two holes in the side of the Vac Float body as shown in <br /> Figure 3. Secure the Vac Float assembly to the housing using two#10 x 1/2" self-tapping screws which <br /> screw into the two holes in the side of the Vac Float. <br /> #10 x 3/8" self-tapping screws TT <br /> (2 each Vac Sensor) <br /> Vac Sensor-STP <br /> Vac Sensor <br /> Siphon port (typ.) housing - back <br /> Vac Sensor housing-front �� (2) #10 x 1/2" self-tapping <br /> screws (typ.ea.valve/vac <br /> float/ass'y.) <br /> p0 ;oo <br /> °0 <br /> o_0 <br /> C�o <br /> (s�..

Get barbed elbows, tapered bushings and cord grip nuts (1 each for each Vac Sensor) from the secondary <br /> piping vacuum monitoring kits. Insert a tapered bushing and barbed elbow in the bottom port labeled VAC <br /> TEST (embossed on cover) of one of the Vac Sensors. Orient the elbows as shown in the Figure 4, then <br /> tighten the cord grip nut. <br /> 8. From the kit's 1/4"tubing, cut a piece of the 1/4"tubing and connect the VAC TEST port in one of the Vac <br /> Sensors to the rear elbow fitting in one of the Vac Floats (preferably the one under it). Keep the connection <br /> kink free and as short as possible (see Figure 4). Repeat this procedure for each additional Vac SensorNac <br /> Float pair. Skip to Step 10. <br /> 9. If the tank interstice is monitored, get a barbed elbow, tapered bushing and cord grip nut (1 each) from the <br /> Vac Sensor tank interstice monitoring kit. Insert a tapered bushing and barbed elbow into the bottom port <br /> labeled VAC TEST (embossed on cover) of the Vac Sensor without a Vac Float. Orient the elbow as shown in <br /> the Figure 5, then tighten the cord grip nut. <br /> 10. Get the barbed tees, tapered bushings, cord grip nuts and one barbed elbow from the vacuum monitoring kits. <br /> 11. Looking at the front of the Vac Sensor housing, insert the elbow in the side vacuum port bushing labeled 'STP <br /> Siphon' (on the Vac Sensor cover) in the Vac Sensor closest to the side of the housing. Orient the elbow so <br /> that the open half is horizontal and pointing to the other Vac Sensors (see Figure 7). Insert a tee in the same <br /> vacuum port in each of the other Vac Sensors. Orient the tees in the horizontal position, except the Vac <br /> Sensor closest to the other side of the Vac Sensor housing. Remove this tee and orient it so that one end <br /> points toward the other tees and one end points out at you then insert the inlet end into the bushing. Measure <br /> and cut a piece of the tubing approximately 1-3/4" (44.5mm) long to connect each of the tees and elbow as <br /> 7 <br />
