valve.
3 . The drain line may be elevated up to 6 feet (1.8 m)
providing the run does not exceed 15 feet (4.6 m) and
water pressure at the softener is not less than 40 psi (2 .76
bar). Elevation can increase by 2 feet (61 cm) for each
additional 10 psi ( .69 bar) of water pressure at the drain
connector .
4 . Where the drain line is elevated but empties into a drain
below the level of the control valve, form a 7-inch (18-cm)
loop at the far end of the line so that the bottom of the loop
is level with the drain line connection. This will provide an
adequate siphon trap .
Where the drain empties into an overhead sewer line, a
sink-type trap must be used .
NOTE: The drain line connects to the elbow previously
installed. It is located between the water line
connections at the rear of the valve.
5 . Use pliers to expand a clamp . Slide the clamp up one end
of the longer length drain line tubing about 1-2 inches and
release .
6 . Push the tubing over the ribbed drain line fitting.
7 . Expand the clamp and move it up the tube to pinch the tube
to the ftitting .
8 . Secure the discharge end of the drain line to prevent it from
moving.

Waste connections or drain outlet shall be
NOTE:
designed and constructed to provide for
connection to the sanitary waste system through
an air-gap of 2 pipe diameters or
1 inch (22 mm) whichever is larger.
WARNING:
Never insert drain line directly into a
drain, sewer line, or trap (Figure 9 Drain
Line Connection). Always allow an air gap
between the drain line and the wastewater
to prevent the possibility of sewage being
back-siphoned into the softener.
Overflow Line Connection
In the event of a malfunction, the salt TANK OVERFLOW will
direct "overflow" to the drain instead of spilling on the floor. This
fitting should be on the side of the cabinet.
To connect the overflow line, locate the tubing connector on the
side of the tank (Figure 10 Tubing Connections) . Attach length
of 1/2-inch (1.3-cm) I.D. tubing to fitting and run to drain. Do
not elevate overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a
direct, separate line from overflow fitting to drain, sewer or tub.
Allow an air gap as per drain line instructions .

Salt Line Connection
The salt line from the brine tube connects to the valve. Make
certain the connections are hand tightened . Be sure that the
salt line is secure and free from air leaks. Even a small leak
may cause the salt line to drain out, and the softener will not
draw salt from the tank . This may also introduce air into the
valve causing problems with valve operation.
To install the brine line:
1 . Inside the salt tank, remove the cap from the large cylinder
to gain access to the connection .
2 . Be sure the brass insert is in the end of the brine tubing .
Insert the tubing through the opening in the tank .
3 . Push the tubing into the plastic nut . Slowly unscrew the nut
until the tubing moves into the connection. The tubing will
hit bottom .
NOTE: Once the tubing has been pushed into the nut
it cannot be pulled out. The nut will need to be
removed. See Figure 11 for correct assembly.
4 . Hand tighten the nut until the connection is tight .
