MANUAL ADVANCE RECHARGE CHECK
This check verifies proper operation of the position
switch, gear motor, brine tank fill, brine draw, recharge
flow rates, and other controller functions. Always make
the Initial Checks (See Page 45) and the Manual
Diagnostics (See Page 46) first.

6
. Remove the brinewell cover.
7
. With the Diagnostics screen displayed, press the
RIGHT (
4
) button once to advance the valve from

to
Fill
.
8
. Shine a flashlight into the brinewell and observe fill
water entering the tank.
9
. If water does not enter the tank, look for an obstruct-
ed nozzle / venturi, fill flow plug or brine tube (See
Figure 154 on Page 43).
10
. After verifying fill, press the RIGHT (
4

to move the valve into
Brine
*. A slow flow of water
to the drain will begin. Verify brine draw from the
brine tank by shining the flashlight into the brinewell
to observe a noticeable drop in the liquid level.

. If the unit does not draw brine, check for:
=
Dirty or defective nozzle / venturi (See Page 43)
=
Nozzle / venturi not seated on the gasket or gas-
ket not sealing properly
=
Restriction in valve drain, causing back pressure
(bends, kinks, elevated too high, etc.)
=
Obstruction in valve or brine tubing
=
Internal valve fault (obstructed outlet disc, wave
washer faulty etc.)
12
. With the Diagnostics screen displayed, once again
press the RIGHT (
4
) button to advance the valve to
Backwash
.
13
. Look for a fast flow of water from the drain hose. If
flow is slow, check for a plugged top distributor,
backwash flow plug or drain hose
14
. With the Diagnostics screen displayed, once again
press the RIGHT (
4
) button to advance the valve to
Fast rinse
.
15
. Again, look for a fast flow of water from the drain
hose. Allow the unit to rinse for several minutes to
flush out any brine that may remain from the brine
cycle test.
16
. With the Diagnostics screen displayed, once again
press the RIGHT (
4
) button to return the valve to
the
Service
