SECTION 1: GENERAL INFORMATION
This 3MAPPM Series Iron Reduction Filtration System reduces dissolved, precipitated and bacterial iron from your water supply. Contrary to conventional
methods, the 3MAPPM Series Iron Reduction Filtration System requires NO chemicals (either added to the water supply or the filter). The unique process
requires ONLY periodic backwashing for a few minutes to flush out entrapped iron that has accumulated in the media tank.
The 3MAPPM Series Iron Reduction Filtration System was designed to be used primarily on jet pump applications where the operating pressures do not exceed
50 psi. The MAXIMUM PRESSURE for proper operation of the aeration tank is 50 psi. If you have a private water system, refer to page 2-1 to determine your
system’s capability. If your system produces the required flow rate at 50 psi or higher, contact your Dealer/Installer or our Customer Care Team at 855-3M-
WATER (855-369-2837).
When properly installed, the 3MAPPM Series Iron Reduction Filtration System will provide years of dependable service. Read this manual all the way through
first, and then follow the instruction steps in the proper sequence.
DESCRIPTION AND OPERATION OF THE SYSTEM:
The 3MAPPM Series Iron Reduction Filtration System consists of two major components which are:
1) An aeration tank, with GAST LOA-P109-AA compressor, installed after the existing pressure tank. Every time the well pump runs, the compressor injects
air into the iron laden water.
2) A backwashing type filter containing a special media that causes the iron to precipitate throughout the filter bed (rather than on the surface as in chemi-
cal oxidizing filters). This process produces an iron reduction capacity from 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 permanganate) for oxygen enrichment, salt,
chlorine or any other chemicals.
The 3MAPPM Series Iron Reduction Filtration System automatically adjusts the pH to neutral or higher on acid water WITHOUT an acid neutralizer (a required
piece of equipment with chemical oxidation filters whenever the pH is less than 6.7). The ability to raise pH when it is below neutral (7 or less) greatly en-
hances the filtration system’s ability to reduce iron efficiently.
IMPORTANT NOTE
Replenishment of the component of the filter media that adjusts pH, “pH Plus”, 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 filter bed flushes the precipitated iron to the drain and readies the filter for use again. The duration of the backwash procedure is
approximately ten (10) minutes. The frequency of backwashing depends on iron concentration and water usage, and ranges from daily to once every twelve
(12) days.
IMPORTANT NOTE
Due to the aeration process, the water will probably appear milky when drawn from the tap. Allow the water to stand and the air will dissipate.
• Professional Installation Required:
Installation requires shutting water off to home, cutting home water supply pipe and using a welding torch
to add piping and fittings. Specialized tools and skills are required. Not a do-it-yourself type of project.
