Installation CONT.

6. Locate Polytube Insert: Now that the water softener is connected to the existing plumbing, the drain

line may be connected. First, locate and remove the polytube insert (#2) from the gray cable on the

left side of the control valve. (See Figure 4)

7. Connecting the Drain Line: Slide plastic nut (#3) over the permanent drain tubing and place the

polytube insert (#2) into the end of the drain tubing. Insert the drain tubing into the drain elbow fitting

(#4) and tighten plastic nut (#3) hand-tight plus 1/2 turn with pliers. Caution: Do Not Over-tighten.

(See Figure 4)

8. Drain Line Specs: If the distance from the water filter to the drain is greater than 20' the drain line

size must be increased to 3/4". The threads on the drain elbow fitting are 3/4" male NPT and can be

used in lieu of the 1/2" plastic nut and insert. If the drain line must run overhead, the maximum height

of the drain line should not exceed 8' above the top of the water softener.

9. Air Gap: The drain line must have an approved air gap to prevent the possibility of a cross connec-

tion to the sewer. (See Figure 5)

10. IMPORTANT: Special precautions must be made when connecting the drainline. During backwash,

high volumes of air and water escape rapidly, causing a flexible drain line to whip and thrash. Rigid

drain piping is highly recommended.
