The LED light will flash under the clock set icon and use the up and
down buttons to adjust to the current time.

buttons to advance to the chosen time.
Press the Menu Scroll button for a third time to display Days between
Regeneration . You may choose 1- 7 days.
Press the Menu Scroll button a fourth time and choose Pounds of salt
to Regenerate . Use the up or down buttons to adjust. The range of salt
pounds available is based on unit size.
Manual regeneration
To manually regenerate the system press the Regenerate Now button.
The control will count down from 10 seconds. To cancel the regener-
ation press the
Menu Scroll button before the countdown is complete.
Once the regeneration has started you may manually advance to each
cycle by pressing and holding the
Menu Scroll button for 5 seconds.
How to Calculate the Regeneration Schedule
1. Calculate the Number of Gallons Used Per Day
The average person consumes about 75 gallons per day. Multiply the
gallons by the number of people in the home (use 4 in this example).
Example: 75 gallons x 4 people = 300 gallons used per day.
2. Calculate the Number of Grains to be Softened Per Day
Use the number of gallons used per day and multiply it by the grains
of hardness in each gallon (use 10 in this example). Add 5 grains for
each part of Iron (1 ppm = 5 grains; 2 ppm iron in this example)
.
Example: 10 grains of ha 10 grains for Iron = 20 grains of hard-
ness. 300 gallons used per day X 20 grains of hardness = 6,000 grains
to be softened per day.
3. Calculate the Days between Regeneration
Divide the capacity of the unit into the grains to be softened per day.
Use the data charts on pages 4-6 to locate the specific capacity for your
model, for the given salting.

Helpful Tip: Use the below fill-in-
the-blank to help compute the
regeneration schedule:
75 gallons x _____ people = _______ gallons used
per day. (
A )
_____ grains of ha _____ grains for Iron
= _____ total grains of hardness. (
B )
_______ gallons used per day ( A from above ) x
_______ total grains of hardness ( B from above )
= _____ grains to be softened per day. ( C )
_________ capacity of unit at given salt ( see
pages 4-6 ) ÷ _______ grains to be softened per
day ( C from above ) = ______ days between regen-
eration
If number is a decimal, round down: ______ days
Helpful Tip: When calculating the
number of people in the home,
consider a washing machine as a
1/2 a person and a dishwasher a
1/2 a person.
