Efficiency Icon
SALT EFFICIENCY: When this feature is ON, the
water softener will operate at salt efficiencies of
4000 grains of hardness per pound of salt or high-
er. The softener may recharge more often using
smaller salt dosage and less water. This softener
is shipped with the efficiency feature set OFF. Use
s
the UP or DOWN buttons to change between
OFF and ON. An efficiency icon will be displayed
when this feature is ON.
California Efficiency Requirement
Your North Star water softener has a "High
Efficiency" feature that can be set ON or OFF.
This softener is shipped with the efficiency fea-
ture set OFF, which will utilize the maximum
rated capacity while most often achieving maxi-
mum salt efficiencies. When installing this unit
in the State of California, you MUST turn the
efficiency feature ON. The softener may initiate
more frequent recharges, but it will operate at
4000 grains per pound of salt or higher.

2. Press SELECT again to display one of the "Clean"
screens shown below.
CLEAN: This feature is beneficial on water sup-
plies containing iron and/or high amounts of sedi-
ments (sand, silt, dirt, etc.). When set to ON, a
backwash and fast rinse cycle will occur first, pre-
ceding the normal regeneration sequence. This
provides extra cleaning of the resin bed before it is
regenerated with the salt brine. To conserve water,
if your water supply does not contain iron or sedi-
ments, be sure this feature is set to OFF. The
default is OFF. Use the
tons to change between OFF and ON.
3. Press SELECT again to display the "Clean Time"
screen shown below.
CLEAN FEATURE MINUTES: If you have set the
Clean Feature ON, the length of the extra back-
wash cycle auto matically is set to 10 minutes.
However, you can ad just this time from 1 to 30
minutes in length. To change this cycle time, use
the UP button to increase the time, or the
s
DOWN button to shorten the time. If no change
is desired, continue to next step.
