Please read the entire Owner's Manual and Instructions before installation.
Water hardness is derived from Calcium and Magnesium minerals that have been dissolved into water under the earth's
surface. These minerals are found in limestone deposits and are the source of hard water. The amount of hardness is a
given water supply is dependent upon the quantity of Calcium and Magnesium present and the length of time water has
been in contact with them. This can vary dramatically from well to well and, for this reason, a water analysis is imperative
in order to determine the proper treatment method. The degree of hardness increases as the concentration of Calcium
and Magnesium ions increases and is measured in Grains Per Gallon (gpg).
The problem of hard water in the home / business comes to light in many facets of daily use. Water spots and scum left
behind in bathtubs, fixtures and showers: wear and tear on appliances: calcium build-up in hot water heaters and piping.:
and greater amounts of soaps and detergents being used are just a few examples.
The modern water softener is designed to reduce hardness ions and their unpleasant side effects. Special resin beads in
the softener mineral tank are used to change hard water into soft water. The surfaces of these beads are covered with
sodium ions. As hard water enters the mineral tank and comes in contact with the resin, an exchange of ions takes place
as dissolved Calcium and Magnesium ions cling to the resin surface and sodium ions take their place, thus softening the
water. This process is called Ion Exchange. Over time, the sodium ions used for the exchange process become depleted
and must be replenished.
The water softener provides a Regeneration process whereby brine solution enters the mineral tank driving-off the
collected hardness ions and replenishes the surface of the resin beads with more sodium ions. The control valve on the
mineral tank automatically initiates this process. The regeneration process has four basic cycles as follows :
1. Backwash – The control valve directs the water flow in a reverse direction through the mineral tank, separating the
resin beads from flushing any accumulated particles to a waste drain.
2. Brine & Rinse – In the first part of this cycle, the control valve directs brine solution downward through the mineral
tank, driving-off collected hardness ions and replenishing the resin beads with sodium ions. The second part of the
cycle rinses hardness ions and excess brine from the mineral tank to the waste drain.
3. Brine Refill – The control valves directs fresh water into the salt compartment to create new brine solution for the
next scheduled regeneration.
4. Service – This is the normal operating cycle where hard water enters the mineral tank, comes into contact with the
resin beads and exchanges hardness ions for sodium ions – the water then becomes soft and ready for use.
A water test should always be performed in order to determine total water hardness (in gpg) and total dissolved iron (in
parts per million (ppm). This is critical for proper equipment selection, sizing and for determining the program for
regeneration frequency. If heavy concentration of iron (above 5 ppm), iron coloration, iron bacteria or sediment is present,
filtration prior to the softener will most generally be required. Certain states may require a licensed plumber for installation.
NOTE :
Flexible water supply connectors and flexible drain line tubing may not be allowed in your locale. Please check
with local plumbing code officials prior to installation.
