2. Press SELECT again to display the “Set Recharge
Days” screen.
MAXIMUM DAYS BETWEEN REGENERATIONS:
The electronic controller automatically determines
recharge fre quency. This provides the greatest
operating efficiency and, under most conditions this
feature will be left in its default mode. However,
you can set this feature to force a recharge every
set number of days. You may want to do this if, for
exam ple, your water supply contains iron and you
want the softener to recharge at least once every
few days to keep the resin bed clean. Use the
r UP or s DOWN buttons to change the number
of days (up to 15).
3. Press SELECT again to display the “12 or 24 hr”
screen.

®
Water Softener has a “High

more frequent recharges, but it will operate at
4000 grains per pound of salt or higher.
