MANUAL ADVANCE REGENERATION CHECK

This check verifies proper operation of the valve

motor, brine tank fill, brine draw, regeneration flow

rates, and other controller functions. Always make

the initial checks, and the manual initiated diag- nostics.

Notes:

The faceplate display must show a steady time (not flashing). If an error code shows, first press the SE-

LECT button to enter the diagnostic display.

_1_ Press the RECHARGE button and hold in for 3

seconds. *RECHARGE and Fill begin to flash (or

clean backwash begins, if set) as the softener en-

ters the fill cycle of regeneration. When FILL is on

steady, remove the brinewell cover and, using a

flashlight, observe fill water entering the tank.

*Note:

If the CLEAN feature is set to ON, a cleaning back- wash (CLEAN and Blcwsh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re-

maining), precedes the recharge.

a. If water does not enter the tank, look for an ob- structed nozzle, venturi, fill flow plug, brine tubing, or brine valve riser pipe.

Note:

Be sure a salt bridge is not preventing water with salt contact.

a. If the softener does not draw brine...

...nozzle and/or venturi dirty or defective.

... nozzle and venturi not seated properly on gasket.

...restricted drain (check drain fitting and hose).

... defective nozzle and venturi seal.

...other inner valve defect (rotor seal rotor & disc, wave washer, etc.).

Note:

If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw.

_1_ Again press RECHARGE to move the softener

into backwash. Look for a fast flow of water from the drain hose.

a. An obstructed flow indicates a plugged top dis-

tributor, backwash flow plug, or drain hose.

_ Press RECHARGE to move the softener into fast

rinse. Again look for a fast drain flow. Allow the

softener to rinse for a few minutes to flush out any brine that may remain in the resin tank from the brining cycle test.

_l-_To return the softener to service, press RE-

CHARGE.

into the brinewell and observing a noticeable drop in the liquid level.
