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
the UP (È) or DOWN (–) buttons to change
between OFF and ON. An efficiency icon will be
displayed when this feature is ON.
