HOW YOUR WATER CONDITIONER WORKS

Water softeners remove hardness in the water by exchanging particles in the water, or ions. They remove hard ions such as calcium and magnesium in the water by trading it
for sodium ions producing soft water. Unlike the calcium and magnesium, sodium stays dissolved in water and does not form a scale. Sodium also does not interfere with the
cleaning action of soaps. The sodium is released by a charged resin contained in the softener, this resin also traps the calcium and magnesium ions. Eventually this resin releases
all of its sodium and has filled up with other ions, so it then must be regenerated. Regeneration is accomplished by washing the resin with a salt saturated brine solution that
removes the calcium and magnesium while replenishing the sodium. This is why the softener requires a brine tank and salt. The water softener can run for days before running
out of sodium, and when it does, the sodium is replenished in only a matter of a few hours
When using a softener to remove both hardness and 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.

of your installer or dealer. Most often this is set at installation for worst case hardness by
the installer.

Reserve Capacity: calculated as 75 gallons per person
Manual Regen Delay: – generally used after servicing the valve so that it will
regenerate at the standard preset regeneraton time. to regenerate immediately either
turn the center knob slightly or change to Immediat and press settings.
Regen Time: This is the time of day that the conditioner is scheduled to regenerate,
this is factory set to 2:00 a.m. it can be adjusted (see page 34)
