INSTALLATION INSTRUCTIONS
D. MOUNTING CONTROL VALVE ASSEMBLY
1. Verify that the distributor riser pipe is not plugged.
2. Lubricate the distributor o-ring on the bottom of the control valve with silicone.
3. Screw the control valve into top opening of tank making sure the distributor riser pipe slides easily through
the distributor o-ring. Care must be taken not to “nick” this o-ring as hard water leakage could result.
4. Tighten down the control valve to ensure positive o-ring seal at top of tank.
E. CONNECT ALL FITTINGS
CAUTION:
Care must be used when working with copper tubing. Do not allow the flame from torch to
contact any noryl portion of the Valve assembly.
1. Attach a minimum of 3/4” drain line to drain elbow.
2. Do not elevate the drain line over 5’ above the top of the valve (8’ on municipal systems) or to exceed 25’ in
length at either height.
CAUTION:
An air gap must be provided upon sewer entry. (Conform to local plumbing and sanitation
codes and ordinances).
3. The salt storage cabinet or brine tank provides an overflow. Attach 1/2” ID flexible plastic tubing to the over-
flow fitting and direct it to the drain.
DO NOT
connect to the main drain line. Use a separate gravity flow
line.
F. PRESSURE TEST THE INSTALLATION
The plumbing system can now be checked for any possible leaks
1. Put the unit into backwash. To do this, push and hold the REGEN button for 3-5 seconds. When the Valve
stops cycling, unplug the unit. With water supply off, put the bypass into the service position.
2. Open water supply line valve very slowly. Water should escape slowly from the drain line. If water enters too
quickly, resin may be lost to the drain.
3. When all of the air has been purged from the mineral tank (water flows steadily from the drain) open the
main supply valve fully.
4. Allow water to run to drain until clear. CHECK FOR LEAKS!
5. Plug the unit back in.
6. Manually step the unit through the remaining steps, stopping at the fill cycle (to do this, push the REGEN
button. The unit will say Brine on the screen). Once the piston has stopped moving, push the REGEN but-
ton again to the next cycle. Continue until Fill appears on the screen. The unit will now fill the brine tank to
the appropriate level. (This sequnce is for softeners with post fill brine)
7. Allow control to return to the home position.
8. Check for leaks!
9. Make sure the power cord is plugged into a properly grounded wall receptacle.
G. MANUAL REGENERATION
The user can initiate manual regeneration. The user has the option to request a manual regeneration at the
delayed regeneration time or to have the regeneration occur immediately:
1. Pressing and releasing the REGEN button. “Regen Today” will flash on the display and the regeneration
will occur at the delayed regeneration time. The user can cancel the request by pressing and releasing
the REGEN button. This method of manually initiating regeneration is not allowed when the system is set to
immediately regenerate when the gallon capacity reaches zero.
2. Pressing and holding the REGEN button for approximately 3 seconds will immediately start the regeneration
The user cannot cancel this request.
