Installation Instructions continued from page 9
10. Install the Drain Line and Air Gap (Air Gap
Not Supplied)
• For all drain lines, use at least a 1/2 inch ID line.
• Connect the drain line to the drain outlet on back of the valve,
opposite the inlet connection (see figure 4). A fitting is required to
connect the female pipe thread to the drain line.
• Run the drain line to the air gap. The air gap must be installed
between the end of the drain line and the drain to prevent possible
back siphoning (see figure 5).
11. Install the Brine Safety Float
• Insert the brine well into the brine tank (see figure 6).
• Attach the brine well to the brine tank with the overflow elbow (see
figure 6).
