Service Tech Information
MANUAL ADVANCE REGENERATION CHECK
This check verifies proper operation of the vaive motor,
brine tank fiii, brine draw, regeneration flow rates, and
other controiier functions. Aiways make the initial
checks, and the manual initiated diagnostics.
NOTE: The faceplate display must show a steady
time (not flashing). If an error code shows, first
press the SELECT button to enter the diagnostic
display.
1. Press the REGENERATiON button and hoid in for 3
seconds. *RECHARGE and Fiii begin to flash (or
ciean backwash begins, if set) as the softener enters
the fiii cycie of regeneration.
*
NOTE: If the CLEAN feature is set to ON, a clean­
ing backwash (CLEAN and Bkwsh or Rinse flashes
in the display, along with the minutes of the clean
cycle remaining), precedes the recharge.
2 . When FiLL is on steady, remove the brineweii cover
and, using a fiashiight, observe fiii water entering the
tank.
3. if water does not enter the tank, iook for an obstruct­
ed nozzie, venturi, fiii flow piug, brine tubing, or brine
vaive riser pipe.
CYCLE FLOW RATES (GALLONS PER MIN.)
FiLL (flow to sait storage tank) 0.3 (1.1 iiters)
BRiNiNG (flow to drain) .22 (.83 iiters)
BRiNE RiNSE (flow to drain) .15 (.57 iiters)
MAX. BACKWASH (flow to drain) 2.0 (7.6 iiters)
MAX. FAST RiNSE (flow to drain) 2.0 (7.6 iiters)
4. After observing fiii, press the REGENERATiON but­
ton to move the softener into brining. A siow flow of
water to the drain wiii begin. Verify brine draw from
the brine tank by shining a fiashiight into the brineweii
and observing a noticeabie drop in the iiquid ievei.
NOTE: Be sure a salt bridge is not preventing water
with salt contact.
5. if the softener does not draw brine:
• nozzie and/or venturi dirty or defective.
• nozzie and venturi not seated properiy on gasket
• restricted drain (check drain fitting and hose)
• defective nozzie and venturi seai
• other inner vaive defect (rotor seai, rotor & disc,
wave washer, etc.)
NOTE: If water system pressure is low, an elevated
drain hose may cause back pressure, stopping
brine draw.

6. Again press REGENERATiON to move the softener
into backwash. Look for a fast flow of water from the
drain hose.
7. An obstructed flow indicates a piugged top distributor,
backwash flow piug or drain hose.
8. Press REGENERATiON to move the softener into
fast rinse. Again iook for a fast drain flow. Aiiow the
softener to rinse for a few minutes to flush out any
brine that may remain in the resin tank from the brin­
