9. Install the Drain Line and Air Gap (Air Gap Not Supplied)
• For all drain lines, use at least a 1/2 inch I.D. line.
• Connect the drain line to the drain outlet on back of the valve, opposite the inlet
connection (see figure 5). A fitting is require to connect the female pipe thread to the
drain line. Run the drain line to the air gap.
• The air gap should be installed between the end of the drain line and the drain to
prevent possible back siphoning (see figure 6).
