SECTION 1: GENERAL INFORMATION
Congratulations on your purchase of a Chem-Free Iron Reduction System! The Chem-Free System reduces dissolved, pre-
cipitated 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 entrapped 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.
The Chem-Free Iron Reduction System is intended to be used on residential water systems which use a standard submersible
well pump, one that utilizes a pressure tank and a pressure switch to stop and start the well pump. If you have a jet pump or
a constant pressure pump you will need to utilize another product type to address your iron, manganese and hydrogen sulfi de
problems. Please contact our technical department should you have any questions at 1-866-693-2543 and select option 1.
Description and Operation of the System:
The Chem-Free Filter System consists of two major components which are:
1) 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 enrich-
ment, salt, chlorine or any other chemicals.
Your Chem-Free Filter System 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.
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 consumptiorate.
Periodic backwashing of the fi lter bed fl ushes the precipitated iron to the drain and readies the fi lter for use again. The dura-
tion 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 99 days.
The volume of water consumed during the entire backwashing procedure is approximately 50 gallons at the factory backwash
settings (one (1) cubic foot models).
