will remove larger particles, but they may not be washed out in regeneration effectively and will eventually foul
the ion exchange resin. A filtering treatment will be required to remove this type of iron.
3. Organic Bound Iron - This type of iron is strongly attached to an organic compound in the water. The ion
exchange process alone cannot break this attachment and the softener will not remove this type of iron.
4. Bacterial Iron - This type of iron is protected inside a bacteria cell. Like the organic bound iron, it is not removed
by a water softener.
When using a softener to remove both hardness and up to 5 ppm of dissolved iron it is important that it regenerates
more frequently than ordinarily would be calculated for hardness removal alone. Although many factors and
formulas have been used to determine this frequency, it is recommended that the softener be regenerated when it
has reached 50 - 75% of the calculated hardness alone capacity. This will minimize the potential for bed fouling.
If you are operating a water softener on clear water iron, regular resin bed cleaning is needed to keep the bed from
coating with iron. Even when operating a softener on water with less than the maximum of dissolved iron, regular
cleanings should be performed. Clean every six months or more often if iron appears in your conditioned water
supply. Use resin bed cleaning compounds carefully following the directions on the container.
Pressure - If pressure exceeds 125 psi (860 kPa), install a pressure reducing valve (see materials checklist). On
private water systems, make sure the minimum pressure (the pressure at which the pump starts) is greater than 20
psi (140 kPa). Adjust the pressure switch if necessary.
CAUTION: The use of a pressure reducing valve may limit the flow of water
in the household.
Temperature - Do not install the unit where it might freeze, or next to a water heater or furnace or in direct sunlight.
LOCATION
Space requirements - Allow 6-12 inches (15-30 cm) behind the unit for plumbing and drain lines and 4 feet (1.3
meters) above for service access and filling the salt container.
Floor surface - Choose an area with solid, level floor free of bumps or irregularities. Bumps, cracks, stones and
other irregularities can cause the salt storage tank bottom to crack when filled with salt and water.
Drain facilities - Choose a nearby drain that can handle the rated drain flow (floor drain, sink or stand pipe). Refer
to the Drain Line Chart, Table 1 (page 10), for maximum drain line length.
NOTICE: Most codes require an anti-siphon device or airgap. Observe all local plumbing codes and drain
restrictions. The system and installation must comply with all state and local laws and regulations.
Electrical facilities - A 10-foot cord and wall mount plug-in transformer are provided. The customer should provide
a receptacle, preferably one not controlled by a switch that can be turned off accidentally. Observe local electrical
codes.
NOTICE: The plug-in transformer is rated for indoor installations only.
