Valve to Tank Installation Instructions
1. Spin the valve onto the tank, ensuring the threads are not
cross-threaded.
NOTE: 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 (Figure 4).

NOTE: If lubricant is required, a silicone compound is
strongly recommended. Dow Corning® Silicone
Compound (available from Watts), is recommended
for best possible results. Dow Corning® 7 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.
WARNING: Do not exceed water pressure of 125 psi
(8.6 bar). Do not exceed 110°F (43.3°C). Do
not subject unit to freezing conditions.
GENERAL INSTALLATION
INSTRUCTIONS
1. Turn off water heater(s).
2. Turn off the main water supply to the home and open an
inside faucet (cold and hot) to relieve any pressure within the
plumbing system.
3. Place the system in the desired installation location. Make
sure that the location is level and sturdy enough to support
the weight of the system once it is in operation.
4. Place the bypass valve in the bypass position.
5. Connect the cold water supply to the inlet of the water
softening system. While constructing the supply line, install
a master supply valve (user supplied) in the supply line and
close it.
6. Connect the feed water line to the home to the outlet of the
system.
7. Plumb the drain line to an appropriate drain abiding buy
all local, city, and state codes. Use a 3/4" drain line for
backwash flow rates that exceed 7 gpm or length that
exceeds 20' (6 m).
8. Connect the brine tank to the water softener control valve
brine inlet port using the factory supplied fittings and tubing.
Add enough water to the brine tank so that water covers the
top of the air check. DO NOT ADD SALT AT THIS TIME.
9. Open the user supplied feed water valve. Check for leaks
and repair as needed.
10. Allow the inside hot and cold faucet to remain open until all
air has been purged from the plumbing system. Then close
the faucet
11. Locate Manual Regeneration Options in this manual
and follow the steps to initiate an Immediate Manual
Regeneration. Once you have read that section place
the system in backwash and unplug the system from
its electrical outlet once it has cycled into the backwash
position. This will stall the unit is backwash so can be
purged from one of the tanks. Look on the right side of the
control valve, it has indicators showing which position the
control valve is in during Regeneration and which tank is
In Service. Tank one has control valve and tank two has
adapter.
12. Adjust the user supplied feed water valve to 1/4 open and
place the bypass valve into the service position.
13. Air will come out of the drain line until the tank in backwash
is completely purged of air. Then water will flow to drain.
Allow water to flow to drain for 15 minutes or until the water
to drain is clear of resin color throw.
14. Plug the system back into the electrical outlet and manually
cycle it through the remaining regeneration steps until it
arrives in the service position.
15. Repeat installation steps 11, 12, 13, and 14 of the General
Installation Instructions to purge the air from the second
tank.
16. Check for leaks and repair as needed.
17. Installation is now complete and the system is ready for
programming and one cycle of brine tank refill so that the
correct amount of water is in the brine tank for the first
regeneration cycle. The brine tank refill must be done after
programming the system.
ProSense Controller Operation
Power Loss Memory Retention
The ProSense controller features battery-free Time of Day and
Day of Week retention during temporary loss of power. A super
capacitor is designed to keep time for 8 to 24 hours depending
on the installation. If the super capacitor is exhausted the
ProSense control will display four dashes (- - : - - ) immediately
upon power up. The Time of Day and Day of Week must be
reset.
All other programmed parameters are stored in the static
memory and are retained.
