Congratulations on your purchase of a Chem-Free Iron Reduction System! The Chem-Free System reduces dissolved, precipitated

and bacterial iron from your water supply. Contrary to conventional methods, your Chem-Free System requires NO chemicals (either

added to the water supply or the ﬁ lter). This unique process requires ONLY periodic backwashing for a few minutes to ﬂ ush out en-

trapped iron that has accumulated in the ﬁ lter tank.

When properly installed, the Chem-Free Iron Reduction System will provide many years of virtually trouble-free service. Read this

manual all the way through ﬁ rst, and then follow the instruction steps in the proper sequence.

Description and Operation of the System:

The Chem-Free Reduction Filter consists of two major components which are:

1) A HYDRO-CHARGER located between the well head and the pressure tank, which adds a small amount of air to the iron-laden

water whenever the well pump runs.

2) A backwashing type ﬁ lter containing a special media that causes the iron in the “Hydro-Charged” water to precipitate throughout the

ﬁ lter bed (rather than on the surface as in chemical oxidizing ﬁ lters). This process produces an iron reduction capacity of 30,000 to

50,000 parts per million (ppm) compared to 6,000 to 8,000 ppm for chemical oxidation processes. The media DOES NOT require

a chemical regenerant (such as potassium permangante) for oxygen enrichment, salt, chlorine or any other chemicals.

Your Chem-Free Reduction Filter automatically adjusts the pH to neutral or higher on acid water WITHOUT an acid neutralizer (a

required piece of equipment with chemical oxidation ﬁ lters whenever the pH is less than 6.7). The ability to raise pH when it is below

neutral (7 or less) greatly enhances the Chem-Free System’s ability to reduce iron efﬁ ciently.

IMPORTANT NOTES

Replenishment of the component of the ﬁ lter media that adjusts pH, “MpH Adder”, may be required periodically, the frequency of

which is dependent on the raw water pH, the manganese (Mn) concentration in the water (if any) and the water consumption rate.

Periodic backwashing of the ﬁ lter bed ﬂ ushes the precipitated iron to the drain and readies the ﬁ lter for use again. The duration of

the backwash procedure will vary depending on several factors, but generally totals just 10 minutes (factory setting). The frequency

of backwashing depends on iron concentration and water usage, and ranges from daily to once every 12 days. The volume of water

consumed during the entire backwashing procedure is approximately 50 gallons (1 cu. ft. models).
