Once the existing Veeder Root 407 sensor has been removed, the technician will fill the annular space with <br />factory supplied brine. Several trips may be required to place more brine, until the air is fully removed from <br />the system. <br />2. Lower the sensor into the riser until drests on the bottom of the reservoir{see Figure 3). Note: Referto the <br />tank manufacturees instructions for setting the proper brine levels. The ideal brine solution level is <br />approximately halfway between the high and lowwater levels. With the Dual -Point Sensor resting on the inner - <br />tank wall, the sensor will alarm when the brine level is below 2" or when the brine level is above 13". <br />3. Install a cord grip bushing/nut into one of the two riser cap fittings. Loosen the nut and push the straight end of <br />the vent tube down through the bushing {ref. Figure 3) about an inch and tighten the cord grip nut. Insert the <br />remaining cord grip bushing and nut from the riser cap kit in the other riser cap fitting. Push the sensor cable up <br />through the loosened second cord grip. Place the cap in the riser and snap down the cap lever to seat the gasket <br />against the inside of the pipe. <br />Vent tube - CAUTION <br />tube must remain clear. <br />14" min. dia.

Install the cord grip from the Cable Seal kit into the fieldjunction box. Push the sensor table into the junction <br />box through the cord grip. Using the wire nuts from the kit, connect the sensor cable to the console cable as <br />shown in Figure 4. Tighten the cord grip. <br />6.
