Inspecting And Handling Your Iron Reduction Filter:

Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.

Handle the ﬁ lter unit with care. Damage can result if dropped or if set on sharp, uneven projections on the ﬂ oor. Do not turn the ﬁ lter unit

upside down.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Installation must comply with existing state or local plumbing codes;

Make Sure Your Water Has Been Thoroughly Tested:

An analysis of your water should be made prior to the selection of your water conditioning equipment. Your dealer will generally perform

this service for you, and may send a sample to the factory for analysis and recommendations. Enter your analysis below for a permanent

record.

IMPORTANT NOTES

• Hydrogen Sulﬁ de (H

S) MUST be tested for at the well site with the well pump running. An on-site test is more accurate for

other contaminants as well and should be performed. For accuracy, the sample must be drawn with the pump RUNNING, and

the test be completed within ONE minute after the sample is drawn.

The following description of the water constituents listed above on the selection of the appropriate Chem-Free model, and their effect on

its operation will help to highlight their signiﬁ cance:

Iron (Fe)

Iron concentrations as low as 0.3 ppm (0.1 ppm under some conditions) will cause staining. The iron concentration, together with the ﬂ ow

rate demand and the consumption rate of the water determines the basic size ﬁ lter system. The higher these factors are, the larger the re-

quired system. The Chem-Free Iron Reduction System is capable of reducing the three main types of iron found in water supplies: Soluble

Iron (also known as clear water iron); Precipitated Iron (also known as red iron); and Bacterial Iron. There is an upper limit of 15 ppm iron

concentration for the Chem-Free System; special care must be taken when selecting a ﬁ lter model if your water has a combination of high

iron, very low pH and/or manganese levels above 0.2 ppm.

The Chem-Free System is not bactericidal, i.e. it does not remove or kill “bacterial iron”. It reduces the iron upon which the bacteria may

live or which it deposits in your plumbing ﬁ xtures, thus helping to eliminate its effects.

Manganese (Mn)

The presence of manganese can be bothersome, even for a Chem-Free Iron Reduction ﬁ lter (and it is devastating for chemical oxidizing

systems). As little as 0.05 ppm of manganese can produce a brownish or black stain. The ability of the ﬁ lter to reduce manganese depends

on its concentration and the pH of the water.

Although not speciﬁ cally designed for the reduction of manganese, the oxidation of manganese is very similar to that of iron. It’s oxidation

is more pH dependent than that of iron, therefore a pH of 8.2 or higher must be obtained. When this pH level is achieved, the precipitation

of manganese may more readily occur. To accomplish this, models are available where the media contains additional quantities of MpH

Adder, the pH raising component (model designations with “M” sufﬁ x). In any application involving manganese, a larger model ﬁ lter is
