Before Installation - 3M 3MAPPM150 Installation And Operating Instructions Manual

Iron reduction filtration systems

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

Handle the filter unit with care. Damage can result if dropped or if set on sharp, uneven projections on the floor. Do not turn the filter unit upside down.

An analysis of your water should be made prior to the selection of your water conditioning equipment and filter media. Enter your water analysis results below

for a permanent record.

Hydrogen sulfide (H 2 S) must be tested for at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the test be completed

within ONE minute after the sample is drawn.

Iron concentrations as low as 0.3 ppm (0.1 ppm under some conditions) will cause staining. The iron concentration, together with the flow rate demand and

the consumption rate of the water determines the basic size filter system. The higher these factors are, the larger the required system. The 3MAPPM Series

Iron Reduction Filtration System is capable of reducing the three main types of iron found in water supplies; Dissolved iron (also known as "clear water" or

ferrous iron), precipitated iron (also known as "red water" or ferric iron) and bacterial iron (also known as iron bacteria). Special care must be taken when

selecting a filter model if your water has a combination of high iron, very low pH and/or manganese levels above 0.2 ppm. The MAXIMUM CONCENTRATION

of iron which can be treated with this system is 10 ppm or less. If your water contains higher concentrations, contact your Dealer/Installer or our Customer

Care Team at 855-3M-WATER (855-369-2837).

The 3MAPPM Series Iron Reduction Filtration System is not bactericidal, i.e. it does not remove or kill "bacterial iron". It reduces the iron and slime deposits

in your plumbing line and fixtures upon which the bacteria may live, thus minimizing its effects.

The pH of water is a measurement of Hydrogen Ion concentration in water. Water with a pH of less than 7.0 is acidic, above 7.0 it is base, and a pH of 7.0 is

neutral. The lower the pH value the greater the acidity, and the higher the pH value the more base. Acidic water (pH less than 7.0) is corrosive to pipes, ap-

pliances, etc. A pH of 7.0 or higher facilitates iron reduction – which is why the 3MAPPM Series Iron Reduction Filtration System is designed to increase the

pH when it is less than 7.0.

The pH increasing component of the media is "sacrificial," that is, it slowly dissolves during the process of increasing pH. The rate this occurs is proportional

to the degree of the pH increase and the water consumption rate (i.e., the greater the pH increase and water consumption, the greater the sacrificial rate).

Thus, when the pH is increased to 8.2 or more, as is necessary when manganese is present, the sacrificial rate is even greater. Under the most severe condi-

tions, the MpH component of the media may have to be replenished two to four times per year. On the other hand, if the raw water pH is 7.0 or above and no

manganese is present, the sacrificial rate is very slight.

Hydrogen sulfide (often referred to as "sulfur"), is easily detectable by its objectionable "rotten egg" odor. Sulfur corrodes iron, brass, copper and silver. While

the 3MAPPM Iron Reduction Filtration System is not intended to be used as a sulfur filter, it is capable of reducing sulfur in concentrations of up to 2 or 3 ppm.

Whenever hydrogen sulfide is present, backwashing must be performed at more frequent intervals.

To avoid unsatisfactory operation or equipment damage, the following system condition must be carefully checked.

The pumping rate of your well pump must be sufficient to BACKWASH the filter. To measure the pumping rate of your pump, follow these instructions:

Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and measure time (in seconds) to refill pres-

sure tank (when pump shuts off). This figure represents CYCLE TIME.
