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.
NOTE:
The face plate display must show a steady
time (not flashing).
1 . Press the ON/OFFĆHOLD button and hold in for
3 seconds. RECHARGE NOW begins to flash as
the softener enters the fill cycle of regeneration.
Remove the brinewell cover and, using a
flashlight, observe fill water entering the tank.
A
.
Ifit does not enter the tank, look for an obĆ
structed nozzle, venturi, fill flow plug, brine tubĆ
ing, or brine valve riser pipe.
CYCLE FLOW RATES (GALLONS PER MIN.)
FILL (flow to salt storage tank) 0.3 (1.1 liters)
BRINING .16 (.6 liters)
BRINE RINSE
(flow to drain)
.11 (.4 liters)
BACKWASH
(flow to drain)
1.8 (6.8 liters)
FAST RINSE 1.8 (6.8 liters)

.
After observing fill, press the ON/OFFĆHOLD
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.
A . Ifthe softener does not draw brine:
- nozzle and/or venturi dirty or defective.
- nozzle and venturi not seated properly on gasĆ
ket.
- restricted drain (check drain fitting and hose).
- defective nozzle and venturi seal.
- other inner valve defect (rotor seal, rotor &
disc, wave washer, etc.).
NOTE:
Ifwater system pressure is low, an elevated
drain hose may cause back pressure, stopping brine
draw.

.
Again press ON/OFFĆHOLD to move the softenĆ
er into backwash. Look for a fast flow of water
from the drain hose.

.
An obstructed flow indicates a plugged top disĆ
tributor, backwash flow plug, or drain hose.
4 . Press ON/OFFĆHOLD 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.
