HC3 2IF Iron Filter Sizing Formula
This iron filter may be programmed to regenerate every 1–12 days. Select the frequency based on the amount
of iron in the water and the number of people in the household.
For optimum performance, program the
water softener to regenerate first, followed by the iron filter.
Example:
Softener 1:00 am; Iron Filter 3:00 am.
Regeneration Cycle Frequency Worksheet
This table will help you determine how often the iron filter will need to regenerate.
Worksheet
Example
Total Iron
____ ppm (mg/L) x 1 = ____ ppm (mg/L)
3.5 ppm (mg/L) x 1 = 3.5 ppm (mg/L)
+ Manganese*
____ ppm (mg/L) x 3 = ____ ppm (mg/L)
0.2 ppm (mg/L) x 3 = 0.6 ppm (mg/L)
+ Sulfur
____ ppm (mg/L) x 5 = ____ ppm (mg/L)
1.0 ppm (mg/L) x 5 = 5.0 ppm (mg/L)
= Total compensated ppm
____ ppm (mg/L)
9.1 ppm (mg/L)

2048 ppm (mg/L)
= Frequency of regeneration
____ days
3.9 days
Set regeneration frequency
@
____ days
3 days
*If manganese is unknown, multiply the iron and sulfur total by 1.15 to adjust total compensated ppm.
Determine Monthly Usage
This table will help you determine how much regenerant the iron filter will use each month.
Worksheet
Example
Total days per month
____ days
30 days
÷ Frequency of regeneration
____ days
3 days
= Regenerations per month
____ regenerations 10 regenerations
x 4 oz per regeneration = oz
KMnO
4
per month ____ oz
4 oz (118 g) x 10 regenerations = 40 oz (1.1 kg)
÷ 16
= lb per month
____ lb
40 oz (1.1 kg) ÷ 16 oz/lb (1 kg/kg)
= 2.5 lb (1.1 kg)
