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 inch (2.6 cm) 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 grease.
Figure 1
4. Lubricate the distributor o-ring seal and tank o-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 plumber 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 inch
(2.5 cm) 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.
