To determine the frequency of regeneration, use this procedure:
Setting the Frequency of Automatic Regeneration (SXT Models)
Please enter the ppm of compensated iron per gallon of water to be removed. See Step #4 of “User
Programming.” The SXT valve will automatically calculate the number of gallons of water to be treated by the
iron filter between regenerations.
How to calculate gallons of water between regenerations:
ppm of capacity between regenerations (see Specifications - Page 1)
÷ ppm of iron in the water sample*
= number of gallons supplied between regenerations
- reserve capacity (number of people x 5 gallons)
Example - Using 5600 SXTM-948CFB
6,000
ppm between regenerations
÷
4
ppm of iron - 4 is the minimum setting of compensated iron [To be entered by the user]
=
1,500
gallons between regenerations [See step #5 of “User Programming”]
–
375
gallons reserve capacity (5 people x 75 gallons)
=
1,125
GALLONS - BETWEEN REGENERATIONS [Calculated by valve]
How to calcuate number of days between regenerations:
Total amount of iron to be removed between regenerations -
÷ ppm of iron to be removed per day
= NUMBER OF DAYS BETWEEN REGENERATIONS
Example:
5
people in the household
x
75
gallons of filtered water per person
=
375
gallons of filtered per day
x
4
ppm of compensated iron - 4 is the minimum setting of compensated iron
=
1,500
PPM OF IRON TO BE REMOVED PER DAY
Using 5600 SXTM-948CFB
6,000
ppm capacity ÷ 2 to ensure adequate reserve capacity
÷
1,500
ppm to be removed per day
=
4*
DAYS BETWEEN REGENERATIONS
*Maximum number of days between regenerations is 12.
