ADJUSTING THE EFFICIENCY
NOTE: Your softener is preset at the factory to 10 lbs. of salt.
To get the best performance from your softener, follow
these steps.
NOTE: California residents are required to leave all softeners
at the factory settings.
1. Have the water analyzed to determine the total hardness
and the ferrous iron concentration. Consult your water
analysis report or contact your local softener distributor or
county agency.
2. Determine your compensated hardness (CH)
CH = (Iron concentration in ppm x 2) +
hardness in grains per gallon (gpg)
i) Example:
Fe (iron) concentration = 3 ppm
Hardness = 25 gpg
CH = (3 x 2) + 25 = 31 grains
3. Using the calculated CH value and the number of people
in your household, find the gallon capacity/salt setting
on the chart below for your model unit. If the CH value is
between the 5-grain increments listed, use the higher value
to determine your capacity/salt setting. For example, if the
calculated CH is 22, use the 25 grains per gallon column.
4. Unplug the unit from the electrical power source.
5. Remove the plate on the back of the timer by removing the
screws.

6. The salt setting adjustment will be found on the brine cam
assembly on the left hand side as you look into the timer
box.
7. To adjust the salt usage, loosen the screw holding the white
cam on the brine cam.
8. Rotate the pointer, on the outer edge of the white cam, to the
correct salt dosage on the Lbs. of Salt label using the chart
below.
9. Once adjusted, tighten the salt cam screw, reattach the back
plate, plug the unit back into its power source, and adjust
the Time-of-Day on the controls.
10. Next change the Gallon Capacity Setting by locating the
program wheel on the right side of the front of the face of
the valve controls. Pull the program wheel forward and align
the gallon capacity (x100) with the white dot to match the
value from the Capacity/Salt Setting chart listed below.
