61AAN WaterMax

Iron Filter Sizing Formula

The WaterMax

Iron Filter may be programmed to regenerate every one to twelve 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. See the 61AAN WaterMax

Iron Filter Sizing Formula.

Regeneration Cycle Frequency Worksheet

This table will help you determine how often the iron filter will need to regenerate.

Water Example

Total Iron ____ ppm x 1 = ____ ppm 3.5 ppm x 1 = 3.5 ppm

+ Manganese* ____ ppm x 3 = ____ ppm 0.2 ppm x 3 = 0.6 ppm

+ Sulfur ____ ppm x 5 = ____ ppm 1.0 ppm x 5 = 5.0 ppm

= Total compensated ppm ____ ppm 9.1 ppm

x Gallons per day for one

person

75 gal 75 gal

= ppm per person per day = ____ ppm 682.5 ppm

x Number of people in household ____ people 4 people

= Daily ppm capacity ____ ppm 2730 ppm

Iron filter capacity = 10,000 ppm 10,000 ppm

÷ Daily ppm requirements = ____ ppm 2730 ppm

= Frequency of regeneration ____ days 3.6 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.

Water 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

per month ____ oz 4 oz x 10 regenerations

= 40 oz

÷ 16 = lb per month ____ lb 40 oz ÷ 16 oz/lb

= 2.5 lb
