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 diagnostics.

NOTES: 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 ON/OFF-HOLD button and hold in for 3 seconds. *RECHARGE and Fill begin to

flash (or clean backwash begins, if set) as the softener enters 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 backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the

clean cycle remaining), 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: If water system pressure is low, an elevated

drain hose may cause back pressure, stopping brine draw.

3. Again press ON/OFF-HOLD to move the

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

at An obstructed flow indicates a plugged top dis- tributor, backwash flow plug, or drain hose.

t Press ON/OFF-HOLD 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.

t To return the softener to service, press ON/ OFF-HOLD.

BACKWASH		(flow to drain)	1.8	(6.8	liters)
BRINE	RINSE	I	.12	(.45	liters)
FAST	RINSE		1.8	(6.8	liters)

2.After observing fill, press the ON/OFF-HOLD button to move the softener into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by

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

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

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

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

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