Hydrostatic Sensor Installation Guide Single-Point Hydrostatic Sensor Installation <br /> Single-Point Hydrostatic Sensor Installation <br /> 1. Turn Off power to the console. <br /> 2. Riser Cap Installation <br /> a. If you have the plastic riser cap kit <br /> Place the cord grip bushing into either of the threaded fittings in the plastic cap and screw the cord grip nut over <br /> the bushing. With the nut loose,push the end of the sensor cable through the cord grip-don't tighten the cable <br /> cord grip at this time.Place the cap in the riser and snap down the cap lever to seat the gasket against the inside of <br /> the pipe. Screw the vent cap down snugly onto the other threaded fitting on the riser cap. <br /> b. If you have the metal riser cap and vent tube <br /> Install the vent tube into one of the cord grips in the metal riser cap(see.Figure 5)and tighten the cord grip. <br /> Loosen the other cord grip and push the sensor cable through it-don't tighten the cable cord grip at this time. <br /> Place the cap in the riser and snap down the cap lever to seat the gasket against the inside of the pipe. <br /> 3. Install the cord grip from the Sensor Install Kit into the field junction box.Push the senor cable into the junction box <br /> through the cord grip.Using the wire nuts from the Sensor Install Kit,connect the sensc r cable to the console cable <br /> as shown in Figure 3. Tighten cord grip. <br /> 4. Seal wire nuts with epoxy sealant following the instructions in the Dual-Point Hydrostatic procedure above(see <br /> Figure 4). <br /> 5. Turn On power to the console. <br /> 6. With the sensor resting on the top of the tank,mark the cable position at the riser cap with a piece of tape. <br /> 7. Pull the sensor up until it triggers an alarm on the console.Mark the cable position at the top of the cap with a piece <br /> of tape. <br /> 8. Lower the sensor until the riser cap is halfway between the taped marks on the cable. <br /> 9. Secure the sensor in position by tightening the cable cord grip in the cap(see Figure 5). <br /> Vent tube-CAUTION 14"min.dia. <br /> tube must remain clear. manhole Cord grip <br /> Concrete slab <br /> or packed earth a ' bG <br /> per NFPA 80 <br /> Riser pipe cap Seal-off <br /> Adjustable lead cable 1/2"rigid conduit <br /> \„ (to Console) <br /> Single-point <br /> hydrostatic sensorWeatherproof field <br /> R Riser pipe wiring junction box <br /> Brine level <br /> .%Reservoir <br /> Double-wall tank <br /> 9ensoreNsinsllf.eps <br /> Figure 5.
