Installation Guidelines:
seconds. This resets the electronics and establishes the
service piston position. The display should flash all wording,
then flash the software version and then reset the valve to the
service position.
• The control valve is compatible with a variety of regenerants
and resin cleaners. The control valve is capable of routing
the flow of water in the necessary paths to regenerate or
backwash water treatment systems. The injector regulates the
flow of brine or other regenerants. The control valve regulates
the flow rates for backwashing, rinsing, and the replenishing of
treated water into a regenerant tank, when applicable.
• Control valve installation is made easy because the distributor
tube can be cut ½" above to ½" below the top of tank thread.
The distributor tube is held in place by an o-ring seal and
the control valve also has a bayonet lock feature for upper
distributor baskets.

Pre-Installation Considerations
A. Water Pressure
A minimum of 25 pounds of water pressure is required for
regeneration valve to operate effectively.
B. Electrical Facilities
A continuous 115 volt, 60 Hertz current supply is required. Make
certain the current supply is always hot and cannot be turned off with
another switch.
C. Existing Plumbing
Condition of existing plumbing should be free from lime and iron
buildup. Piping that is built up heavily with lime and/or iron should
be replaced. If piping is clogged with iron, a separate iron filter unit
should be installed ahead of the water softener.
D. Location Of Softener And Drain
The softener should be located close to a drain.
E. Bypass Valves
Always provide for the installation of a bypass valve.
F. Valve to Tank Installation Instructions
1. Spin the valve onto the tank, ensuring the threads are not cross-
threaded.
NOTICE
The main control valve and tank adaptor have right-hand threads, or
clockwise, to install
2. Rotate the valve freely without using force until it comes to a stop
(this position is considered zero).
3. Rotate the valve clockwise from zero, between ¼ turn and ½
turn to fully tighten. No tools are needed. Hand tight is enough.
Overtightening may cause valve or tank damage.
NOTICE
If lubricant is required, a silicone compound is strongly
recommended. Dow Corning
Watts), is recommended for best possible results. Dow Corning
Release Compound is used in the manufacture of this control valve.
The use of other types of lubricants may attack the control's plastic
or rubber components. Petroleum-based lubricants can cause
swelling in rubber parts, including O-rings and seals.
