Capacity and Salt Settings
As mentioned previously, the softener will regenerate once the amount of water equal to the treated water volume set point has
passed through the turbine for meter models or after a xed time interval for timeclock models. Regeneration is either delayed
until the selected regeneration time or immediate depending on how the microprocessor is programmed. Before completing the
programming, the following information must be determined:
1. Compensated Water Hardness. - If your water supply contains iron, compensate for it by the following procedure:
a. Multiply the iron by 0.1 and add the result to the hardness.
Example: (3 ppm of iron x 0.1) + 25 gpg of hardness = 25.3 gpg of total hardness
b. Choose the % capacity you want and refer to the table below for the appropriate multiplier.
Example: 67% capacity gives a multiplier of 1.5.
Table 4

Multiplier

c. Multiply the result from Step 1 by the multiplier chosen in Step 2. This is the compensated hardness.
Example: 25.3 gpg total hardness x 1.5 = 38 gpg compensated hardness.
d. Use the effective hardness for sizing and to determine salt dosage and regeneration frequency.
e. The forced regeneration feature should be used for Soft-Minder meter operation to ensure the resin bed does not become
iron fouled due to lack of water ow. See “Programming the Option Settings” for the forced regeneration feature.
2. Salt Dosage - From Table 5, select the salt dosage at which the softener will be operated.
a. Low Setting — Maximum salt efciency, more frequent regeneration, reduced overall softening capacity.
b. Medium Setting — Good combination of efciency and overall softening capacity.
c. High Setting — Maximum softening capacity, less frequent regeneration, and reduced salt efciency. Recommended
whenever iron is present and for hardness levels above 30 Grains Per Gallon, or high volume water usage.
3. Treated Water Volume Set Point - Calculate the treated water volume set point using the following information:
a. Softening capacity — Grains (based upon salt dosage setting).
b. Compensated hardness of water supply — Grains Per Gallon
c. Estimated daily water usage — Gallons Per Day (refer to Table 5)
