Testing was performed using pellet grade sodium chloride as the regenerant salt.
** Efficiency rating is valid only at the lowest stated salt dosage. These softeners were efficiency rated according to
NSF/ANSI 44.
*** Extent of iron removal may vary with conditions. Use of Diamond Crystal
improve iron removal. Refer to Cleaning Iron Out of the Water Softening System section.

Sanitizing Procedures
To complete the installation, do the following
sanitizing procedures.
Care is taken at the factory to keep your
water softener clean and sanitary. Materials
used to make the softener will not infect or
contaminate your water supply and will not
cause bacteria to form or grow. However,
during shipping, storage, installing and
operating, bacteria could get into the
softener. For this reason, sanitizing as
follows is suggested when installing.
NOTE: Sanitizing is recommended by the
Water Quality Association for disinfecting.
1. Be sure to complete all installation steps,
including programming the control.
2. Pour about 3/4 oz. (1

common 5.25% unscented household bleach
(Clorox, Linco, Bo Peep, White Sail, Eagle,
etc.) into the brinewell. Refer to illustration
on page 5.
3. IMPORTANT: Press and hold for 3 seconds
the faceplate RECHARGE
an immediate recharge. RECHARGE begins
to flash in the display. The bleach will be
drawn through the water softener and out
the drain. This process takes approximately
2 hours.

4. If, after sanitization, water from the house
faucet tastes salty or has a slight color, this is
a preservative from the resin tank. Turn on
the cold soft water faucets and drain for a
few minutes or until clear.
NOTE: When the sanitizing recharge is over,
your house COLD water supply is fully soft
immediately. However, your water heater is
filled with hard water and as hot water is used,
it will refill with soft water. When all the hard
water is replaced in the water heater, hot only
and mixed hot and cold water will be fully soft.
If you want totally soft water immediately, after
the above recharge, drain the water heater
until the water runs cold.
WARNING:
If you do drain the
water heater, use extreme care as the hot
water could cause burns. Turn the water
heater off prior to draining.
