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 Rost 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 'P Y$YY YY rT <br /> (2 each Vac Sensor) I I <br /> Vac Sensor-STP Vac Sensor <br /> Siphon port(typ.) housing-back <br /> Vac Sensor housing-front—�, (2)#10 x 1/2"self-tapping <br /> 0,66 screws(typ.ea.valve/vac <br /> pe floattaass'y.) <br /> m <br /> �Pc,c wqf ss <br /> Left hand asst' rxw'rc.t ~,Mp"gyms <br /> Right hand assy <br /> Flgure& Attaching four Vac Sansors/Floeb to the housing <br /> 7. 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 /> 6 <br />
