I <br /> I <br /> t <br /> s <br /> Dual-Point Hydrostatic Sensor Installation <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 manufacturer's 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 /> 14"min.dia. <br /> manhole Cord grip nuttbushing <br /> / (vent cap not shown) <br /> Concrete slab 8 a a <br /> or packed earth p <br /> per NFPR N <br /> Riser pipe cap Seal-off <br /> Dual-point Weatherproof 112"rigid <br /> hydrostatic sensor junction conduit <br /> (to Console) <br /> Float <br /> Brine level <br /> Reservoir <br /> Double-wall <br /> tank <br /> 6ensoreV�89enaReAs <br /> Figure 2.

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 />
