Hydrostatic Sensor Installation Guide Single-Point Hydrostatk SensorinstaHatkn <br /> Single-Point Hydrostatic Sensor Installation <br /> 1. Turn Off power to the console. <br /> 2, Miser 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 <br /> nut over the bushing.With the nut loose,push the end of the sensor cable through the cord grip-don't <br /> tighten the cable cord grip at this time.Place the cap in the riser and snap down the cap lever to seat the <br /> gasket against the inside of the pipe.Screw the vent cap down snugly onto the other threaded fitting on <br /> 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(ref.Figure 5)and tighten the cord <br /> grip.Loosen the other cord grip and push the sensor cable through it-don't tighten the cable cord grip at <br /> this time.Place the cap in the riser and snap down the cap lever to seat the gasket against the inside of the <br /> pipe. <br /> 3. Install the cord grip from the Sensor Install Kit into the field junction box.Push the sensor cable into the <br /> junction box through the cord grip.Using the wire nuts from the Sensor Install Kit,connect the sensor cable <br /> to the console cable 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(Step 6. <br /> )above. <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 <br /> a piece 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 I Cord grip <br /> Concrete slabI o <br /> or packed earth <br /> per NFPA 80 ��' a <br /> d 6 <br /> Riser pipe cap "'�-Seal-off <br /> Adjustable lead cable 1/2"rigid conduit <br /> (to Console) <br /> Single-point Weatherproof Heid <br /> hydrostatic sensor <br /> Riser pipe wiring junction box <br /> Brine level'__ <br /> r--Reservoir <br /> Double-wall tank <br /> wnaorsWewnLepa <br /> Figure 5.
