Programming the Water Softener
EXTRA RECHARGE
Sometimes, a manually initiated recharge (regenera-
tion) may be desired, or needed. Two examples are:
You have used more water than usual (guests visit-
=
ing) and you may run out of soft water before the
next automatic regeneration.
You did not add salt to the softener before it ran
=
out. Add salt to the softener before regenerating.
You can start a regeneration immediately, or you can
set the controller to regenerate at the next preset
recharge time (2:00 AM, or as set).
RECHARGE NOW
Press the RECHARGE button and hold for 3 sec-
onds, until the words "RECHARGE NOW begin to
flash in the display
The softener enters the fill cycle of regeneration
immediately. This regeneration will take about 2 hours
to complete. Then, you will have soft water again.
NOTE: If the "Clean Feature" is set ON, the normal
regeneration cycle is preceded by a cleaning
backwash and rinse.
RECHARGE TONIGHT
If you do not want to start an immediate recharge, but
would like an extra recharge at the next preset
recharge start time, do the following to schedule a
recharge:
Press and release (do not hold) the RECHARGE but-
ton. "RECHARGE TONIGHT" will begin flashing in
the display, and the softener will begin regeneration
at the next preset recharge time (2:00 AM, or as set).
If you decide to cancel the regeneration before it
starts, press and release the RECHARGE button
once more. "RECHARGE TONIGHT" will stop flash-
ing in the display.
PROGRAM MEMORY
If electrical power to the softener goes off, the time
display is blank but the electronic controller keeps the
correct time for several hours. When electrical power
comes on again, you will have to reset the present
time only if the display is flashing. The HARDNESS
and RECHARGE TIME never require resetting unless
a change is desired. Even if the clock is incorrect
after a long power outage, the softener works as it
should to keep your water soft, however, regenera-
tions may occur at the wrong time of day until you
reset the clock to the correct time of day.
CLEANSING FEATURE
The cleansing feature keeps larger particles of sedi-
ment from entering the home's plumbing system. As
water passes through the softener, the larger sedi-
ment particles are collected in the integrated basket
and then rinsed to the drain before each regenera-
tion. The cleansing feature provides added protection
for water using appliances by reducing the chance of
larger particles entering the various products valves
and screens. The "Clean Feature" may be turned ON
FIG. 27
to provide an extra backwash that will help keep the
cleansing screen clean. The default is OFF.
IMPORTANT: The cleansing feature is not intended to

replace pretreatment filtration. For
problem water applications, additional
sediment filtration is recommended.
