Aqua-Pure APPM150 - Manual (Page 4)

SECTION 1: GENERAL INFORMATION
This APPM Series Iron Reduction Filtration System reduces dissolved, precipitated and bacterial iron from your water supply. In addition, the system reduces
manganese and hydrogen sulfi de, as well as elevating low pH. Contrary to conventional methods, the APPM Series Iron Reduction Filtration System requires
NO chemicals (either added to the water supply or the fi lter). The unique process requires ONLY periodic backwashing for a few minutes to fl ush out en-
trapped iron that has accumulated in the media tank.
The APPM Series Iron Reduction Filtration System was designed to be used primarily on jet pump applications where the operating pressures do not exceed
50 psi, as well as with variable speed constant pressure pumps and in split stream water system designs. 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
fl ow rate at 50 psi or higher, contact your Dealer/Installer or our Customer Service Department at 1-800-222-7880.
When properly installed, the APPM Series Iron Reduction Filtration System will provide years of dependable 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 APPM 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 fi lter containing a special media that causes the iron to precipitate throughout the fi lter bed (rather than on the surface as in chemi-
cal oxidizing fi lters). 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 APPM 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 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 fi ltration system’s ability to reduce iron effi ciently.
IMPORTANT NOTE IMPORTANT NOTE
Replenishment of the component of the fi lter 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 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 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 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.
