-Installation Procedure-
- Water Supply Connections and Bypass Valve -
To allow for softener servicing, swimming pool filling or lawn sprinkling, a manual bypass valve has been installed
at the factory. The bypass allows hard water to be manually routed around the softener.
1. Position softener at desired location for installation. (See Installation Diagrams.)
2. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
3. Cut main line and install appropriate elbows and extensions. Inlet and outlet connections on the control valve are 3/4”
FNPT.
Caution:
Raised arrows located on the sides of control valve body and bypass valve indicate proper direction of water
flow. Install inlet and outlet piping in direction of arrows. It is recommended that a vacuum breaker be installed
on the inlet plumbing.
4. Rotate bypass valve to the bypass position (position of lever is at right angle to inlet / outlet piping).
5. Turn the main supply line on to restore water service to the home.
6. OPEN nearest faucet to evacuate air and repressurize plumbing lines.
7. Check for leaks!

- Drain Line Connection -
1. The drain line flow control assembly is pre-assembled for your convenience. Should you choose to hard plumb the
drain line, please remove the barb fitting. The flow control housing can be removed by removing the clip and pulling
straight out on housing.
Note:
When re-installing the drain line flow control housing, be sure you hear and feel the O-Ring pop into place before
inserting the clip.
2. Install 1/2” I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between end of the drain line
and the open drain is required to prevent waste water backflow. Keep the drain line as short as possible. An overhead
drain line can be used if necessary, but should discharge below the control valve. A syphon trap (taped loop) at the
outlet of the drain line is advisable to keep the drain line full and assure correct flow during backwash. Elbows or other
fittings must be kept at a bare minimum.
Note:
Where the drain line is elevated above the control valve or exceeds 20 feet in length, 3/4” I.D. drain line tubing
should be used.
