Installation Instructions
Contact your local distributor to use WaterGroup laboratory for complete water analysis free of cost
and no obligation to you.
All government codes and regulations governing the installation of these devices must be observed.
If the ground from the electrical panel or breaker box to the water meter or underground copper pipe is tied
to the copper water lines and these lines are cut during installation of the Noryl bypass valve and/or poly
pipe, an approved grounding strap must be used between the two lines that have been cut in order to main-
tain continuity. The length of the grounding strap will depend upon the number of units being installed and/or
the amount of copper pipe being replaced with plastic pipe. See Figure 1.
In all cases where metal pipe was originally used and is later interrupted by poly pipe or the Noryl bypass valve as in Figure
1 or by physical separation as in Figure 2, an approved ground clamp with no less than #6 copper conductor must be used
for continuity, to maintain proper metallic pipe bonding.
NOTE: Check your local electrical code for the correct clamp.
Before Installation
Inspecting and Handling Your Chemical Free Iron Filter
Inspect the equipment for any shipping damage. If damaged, notify the transportation company and request a damage
inspection. Damage to cartons should also be noted.
Handle the filter unit with care. Damage can result if it is dropped or set on sharp, uneven projections on the floor.
Do not turn the filter unit upside down.
NOTE: If a severe loss in water pressure is observed when the filter unit is initially placed in service, the filter tank
may have been laid on its side during transit. If this occurs, backwash the filter to “reclassify” the media.
iron (Fe)
Iron concentrations as low as 0.3 ppm will cause staining. The iron concentration, together with the flow rate demand and
the consumption rate of the water, determines the basic size of the filter system. The higher these factors are, the larger
the required system. The filter system is capable of filtering out the three main types of iron found in water supplies: soluble
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). There is no apparent upper limit of iron concentration for the filter but 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.
Manganese (Mn)
The presence of manganese can be bothersome, even for a chemical free iron filter. As little as 0.05 ppm of manganese
can produce a brownish or black stain. The ability of the filter to remove manganese depends on its concentration and
the pH of the water.
Manganese tends to “coat” the filter media, rendering it incapable of increasing the pH and, therefore, ineffective
in removing either the iron or the manganese. Manganese, however, will precipitate in the filter bed when the pH is
increased. To accomplish this, a special “M” type media that contains additional quantities of the pH raising component
(“MpH adder”) can be provided. The use of “M” type media is for applications where the manganese is not more than 1.5
ppm, and the pH is 6.0 or higher. When the pH is below 6.0, consult your dealer.
