Drain Line Connection
Refer to Table 3 for drain line length and height limitations under the applicable tank size.
1. Remove 3/4" pipe clamp from the small parts pack included with the control.
2. Route a length of 3/4" 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 dis-
charge point. The system and installation must comply with state and local laws and regulations.
