ELECTRONIC DEMAND TIMER FEATURES, AND SERVICE, continued
service: 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. First,
make the initial checks, and the manual initi-
ated diagnostics.
NOTE: The face plate display must show a
steady time (not flashing).
1. Press the RECHARGE button and hold in for
3 seconds. RECHARGE NOW begins to flash
as the softener enters the fill cycle of regenera-
tion. Remove the brinewell cover and, using a
flashlight, observe fill water entering the brine
tank.
#If water does not enter the tank, look for an
obstructed nozzle, venturi, fill flow plug, brine
tubing, or brine valve riser pipe.
2. After observing fill, press the RECHARGE 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 liq-
uid level.
NOTE: Be sure a salt bridge is not preventing water
with salt contact.
#
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.
3. Again, press the RECHARGE button to move the
softener into backwash. Look for a fast flow of water
from the drain hose.
#
A slow flow indicates a plugged top distributor,
backwash flow plug, or drain hose.
4. Press RECHARGE to move the softener into fast
rinse. Again look for a fast drain flow. Allow the sof-
tener to rinse for a few minutes to flush out any
brine that may remain in the resin tank from the brin-
ing cycle test.
5. To return the softener to service, press
RECHARGE.
