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. 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"
(2.5 cm) of water above the grid (if used) in the brine tank.
15. Fill the brine tank with salt.
16. Allow the control to run automatically. Setup is now complete.
Figure 1
Multiple System Shutoff
For systems requiring no hard water bypass, a solenoid
operated diaphragm valve can be installed in the service outlet
pipe (see Figures 2, 3, and 4). The solenoid would be connected
to the 24 VAC Bypass Relay terminal strip on the lower left
portion of the NXT circuit board (Figure 6 7000NXT Circuit
Board).
Plastic solenoid operated diaphragm valves are sold separately
from the pipe adapter kits. For each valve ordered, one
hardware kit, and one pipe adapter kit is required. Available
plastic valve configurations include:
