*If your water supply is 15 grains ha rd and you dr ank 3 quar ts of softened water you would

consume 335 milligrams of sodium. That is equivalent to eating 2--1/2 slices of white bread.

**One large banana, about 9 inches in length, has approximately 600 milligrams of potassium.

2. Iron in water can cause stains on clothing and plumbing fixtures. It can negatively affect the taste

of food, drinking water, and other beverages. Iron in water is measured in parts per million (ppm).

The total* ppm of iron, a nd type or types*, is de termined by chemical analysis. Four different types

of iron in water are:

Ferrous (clear water),

Ferric (red water),

Bacterial and organically bound iron,

Colloidal and inorganically bound iron (ferrous or fe rric).

*Water may contain one or more of the four types of iron and any combination of these. Total iron

is the sum of the contents.

Ferrous (clear water) iron is soluble and dissolves in water . This water softener will remove

moderate amounts of this type of iron (see specifications). Ferr ous (clear water) iron is usually

detected by taking a sample of water in a clear bottle or glass. Immediately after taking, the sample

is clear. As the w ater sample stands, it gradually clouds and turns slightly yellow or brown as air

oxidizes the iron. This usually occurs in 15 to 30 minutes.

When using the softener to remove Ferrous (clear water) iron, add 5 grains to the hardness setting

for every 1 ppm of Ferrous (clear wa ter) iron.
