Water Softener Control Valve
Water Pressure
A minimum of 25 psi inlet water pressure is required for regeneration valve to operate effectively.
Electrical Facilities
An uninterrupted alternating current (A/C) supply is required. Make sure:
Voltage supply is compatible with unit before installation.
Current supply is always hot and cannot be turned off with another switch.
Existing Plumbing
Condition of existing plumbing should be free from lime and iron buildup. Replace piping that has heavy lime
and/or iron build-up. If piping is clogged with iron, install a separate iron filter unit ahead of the water softener.
Location of Softener and Drain
Locate the softener close to a clean working drain and connect according to local plumbing codes.
Bypass Valves
Always provide for the installation of a bypass valve if unit is not equipped with one.
NOTE:
This product should be installed by qualified personnel.
Comply with all plumbing codes when installing this product.
Comply with all electrical codes when installing this product.
CAUTION
Minimum water pressure 20 psig.
Maximum water pressure 125 psig.
Minimum water temperature 34° F.
Maximum water temperature 110° F.
Ambient temperature 34° to 122° F (1° to 50° C)
Disconnect all power sources before servicing.
Always operate with cover in place.
WARNING
The controller MUST be depressurized before removing
any quick connection clips for servicing. The connector
should be pushed toward the control while removing clips.

Valve Installation and Start-up Procedures
Installation Instructions
1.
Place the softener tank where you want to install the unit.
NOTE:
Be sure the tank is level and on a firm, clean base.
2.
Perform all plumbing according to local plumbing codes.
3.
Cut the 1.05" (32mm) distributor tube flush with the top of
the tank (A).
Deburr the outside of the tube (B) after cutting.
Lubricate the o-ring (C) with non-petroleum based oil.
4.
Lubricate the distributor 0-ring seal and tank 0-ring seal.
Use only non-aerosol silicone lubricant.
5.
Load media and place the control valve on the tank.
6.
All soldering MUST be done on any connections requiring soldering prior to connecting the main control valve.
The main control valve will by damaged if it is connected at the time of soldering.
7.
Apply
Teflon
tape to all threaded fittings.
8.
On units with a bypass, place in Bypass position.
Turn on the main water supply.
Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign
material (usually solder) resulting from the installation. Close the water tap when water runs clean.
9.
Make plumbing connections to valve.
10. Plug the valve into an approved power source.
NOTE:
Make all electrical connections according to codes.
11. Place the bypass In Service position. Cycle the valve to the Backwash position, and let the water flow slowly
into the mineral tank until the air is purged from the unit.
12. Add water to the brine tank until the top of the air check is covered. Manually step the valve to the Brine Draw
Position, and allow the valve to draw water from the brine tank until it stops.
NOTE:
The air check will check at approximately the midpoint of the screened intake area.
13. Manually step the valve to the Brine Refill Position, and allow the valve to return to In Service automatically.
14. With the valve In Service, check that there is at least 1" of water above the grid in the brine tank, if used.
15. Fill the brine tank with salt.
16. Allow the control to run automatically. Setup is now complete.

7000 Control Operation and Settings
Display
Time Clock Regeneration Valves
In normal operation the Time of Day Display may be viewed at all times. The control operates for a preset number
of days between Regeneration cycles. When the number of days since the last Regeneration reaches the preset
number of days, a Regeneration cycle initiates at the preset Regeneration Time.
NOTE:
Program the number of days between Regeneration cycles and the Regeneration time using the
7000 Control Start-Up Procedur
