Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection. Handle the fi lter with care. Damage
can occur if dropped or set on sharp, uneven projections on the fl oor. Do not turn the fi lter upside down. Installation must comply with state and local laws and
regulations.
An analysis of your water should be made prior to the selection of your water conditioning equipment. Your dealer will generally perform this service for you,
and may send a sample to the factory for analysis and recommendations. Enter your analysis below for your permanent record.

Iron concentrations as low as 0.3 ppm (0.1 ppm under some conditions) will cause staining. The iron concentration, together with the fl ow rate demand and the
consumption rate of the water determines the size of the fi lter system required. The higher these factors are, the larger the required system. The Iron Reduction
System is capable of reducing the three main types of iron found in water supplies: Soluble Iron (also known as clear water iron); Precipitated Iron (also known as
red iron); and Bacterial Iron. There is an upper limit of 15 ppm iron concentration for the Iron Reduction System; special care must be taken when selecting a fi lter
model if your water has a combination of high iron, very low pH and/or manganese levels above 0.2 ppm.
The Iron Reduction System is not bactericidal, i.e. it does not remove or kill "bacterial iron". It reduces the iron upon which the bacteria may live or which it deposits
in your plumbing fi xtures, thus helping to minimize its effects.
The presence of manganese can be bothersome, even for an Iron Reduction System (and is problematic for chemical oxidizing systems because the chemicals may
not allow for the correct pH for Manganese Reduction). As little as 0.05 ppm of manganese can produce a brownish or black stain. The ability of the Iron Reduction
System to reduce manganese depends on its concentration and the pH of the water.
Although not specifi cally designed for the reduction of manganese, the oxidation of manganese is very similar to that of iron, therefore, a pH of 8.2 or higher must be
obtained. When this pH level is achieved, the precipitation of manganese may more readily occur. To accomplish this, models are available where the media contains
additional quantities of MpH Adder, the pH raising component (model designations with "M" suffi x). In any application involving manganese, a larger model fi lter is
generally recommended (but only if the pumping rate is suffi cient to backwash the larger size).
If, however, the manganese concentration is low (0.1 ppm or less) and the pH is 6.5 or higher, an Iron Reduction System containing standard Iron Reduction System
media will generally perform satisfactorily, although backwashing should be performed at more frequent intervals. Under more severe conditions where the pH is
very low and/or the manganese concentration is high, an acid neutralizer installed ahead of the Iron Reduction System will maintain the required 8.2 pH level longer
than the Chem-Free media will between replenishment with MpH Adder.
The pH of water measures its acidity. Water with a pH of less than 7.0 is acidic, above 7.0 it is alkaline, 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 alkaline. Acidic water (pH less than 7.0) is corrosive to pipes, appliances, etc. A pH of 7.0 or higher facilitates iron
reduction, which is why the Iron Reduction System is designed to increase the pH when it is less than 7.0.
The pH increasing component of Chem-Free media is "sacrifi cial", that is, it slowly dissolves during the process of increasing pH. The rate at which 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 sacrifi cial
rate). Thus, when the pH is increased to 8.2 or more, as is necessary when manganese is present, the sacrifi cial rate is even greater. Under the most severe condi-
tions, the MpH Adder 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 sacrifi cial rate is very slight (see IMPORTANT NOTE, Section 1).
