in the
display
and the filter moves

O.UU
RECHARGE
NOW
...If the motor does not run, check the motor and
all wiring connections.
Check for fill water flow to the brine tank. If water
does not enter the tank, look for an obstructed
nozzle and venturi,
fill flow plug or brine tubing.
2. After verifying fill, press the RECHARGE
but-
ton to move the valve into brining.
A slow flow of
water
to the drain will begin. Verify brine draw
from the brine tank by shining the flashlight
into
the brinewell
and observing
a noticeable
drop in
the liquid level.
If the unit does not draw brine, check for...
...dirty or defective nozzle and venturi
...nozzle and venturi
not seated on the gasket, or
gasket defective
...restriction
in valve drain, causing a back- pres-
sure (bends,
kinks,
elevated
too high,
etc.),
...obstruction
in brine
valve
or brine
tubing
...inner
valve
failure
(obstructed
rotor
disc, wave
washer
defective,
etc.)
NOTE:
Be sure a salt bridge
is not preventing
con-
tact of the water
with salt.
3. Again press the RECHARGE
button to move
the valve into backwash.
Look for a fast flow of
water from the drain hose (see specifications,
page
4-1).
...An obstructed
flow indicates a plugged
top dis-
tributor, backwash
flow plug, or drain hose.
Be sure household
water pressure
(well system) is
maintained
at a minimum
of 20 psi. Adjust the
pump switch upward,
if needed.
4. Press the RECHARGE
button to move the filter
into fast rinse. Again, look for a drain flow rate
about the same as backwash.
5. To return the filter to service, press the RE-
CHARGE button once.
