Drain Line Connection
Refer to Table 3 for drain line length and height limitations under the applicable tank size.
1. Remove 1/2" pipe clamp from the small parts pack included with the control.
2. Route a length of 1/2" drain line from the drain elbow to the drain.
3. Fasten the drain line to the elbow with the clamp.
4. Secure the drain line to prevent its movement during regeneration. When discharging into
a sink, or open floor drain, a loop in the end of the tube will keep it filled with water and
will reduce splashing at the beginning of each regeneration.
NOTE Waste connections or drain outlets shall be designed and constructed to
provide for connection to the sanitary waste system through an air gap of
two pipe diameters or 1 inch, whichever is larger.
NOTE Note: Observe all plumbing codes. Most codes require an anti-siphon
device or air gap at the discharge point. The system and installation must
comply with state and local laws and regulations.

Brine System Assembly—Duplex Models
Models using a common brine tank should
be assembled as follows:
1. Cut off approximately two inches
of brine tubing, then attach the
tubing to the brine safety valve.
See Figure 17.
2. Connect the center leg of the
duplex tee (provided in the small
parts pack) to the other end of the
tubing.
3. Connect the brine line tubing from
each softener to the two remain-
ing ends of the duplex tee. The
nut and insert are provided in the
small parts pack.
