Hydrostatic <br />1. Turn Off power to the console. <br />2. Lower the sensor into the riser until it rests on the bottom of the reservoir (see Figure 2). Note: Refer to the <br />tank manufacturers instructions for setting the proper brine levels. The ideal brine solution level is <br />approximately halfway between the high and low water levels. With the Dual -Point Sensor resting on the <br />inner -tank wall, the sensor will alarm when the brine level is below 2" or when the brine level is above 12 <br />Figure 2. Dual -Point Sensor Installation (shown with plastic riser cap) <br />3. 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 <br />nut over the bushing. With the nut loose, push the end of the sensor cable through the cord grip. Place <br />the cap in the riser and snap down the cap lever to seat the gasket against the inside of the pipe. Screw the <br />vent cap from the kit down snugly onto the other threaded fitting of 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 on page 7) and tighten <br />the cord grip. Loosen the other cord grip and push the sensor cable through it. Place the cap in the riser <br />and snap down the cap lever to seat the gasket against the inside of the pipe. <br />4. With the sensor still resting on the bottom of the reservoir, leave a little slack in the sensor cable and tighten <br />the cable cord grip nut. <br />5 <br />14" min. dia. <br />manhole Cord grip nut/bushing <br />(vent cap not shown) <br />Concrete slab <br />or packed earth <br />per NFPA 80 <br />Riser pipe cap ' <br />— --- Seakoff <br />Dual -point <br />Weatherproof 1/2" rigid <br />hydrostatic sensor ----� <br />junction conduit <br />�kj (to Console) <br />Float _,_ <br />Brine level <br />Reservoir <br />Double-wall <br />/ tank <br />sensorsftsenap.eps <br />Figure 2.
