BASIC PRINCIPLES
A water softener works via a process known as Ion Exchange. In this process, a special media bed is used to exchange undesirable hardness minerals,
including calcium, potassium, and magnesium (as well as low levels of iron and manganese) for something more desirable -- in this case, a small amount
of sodium.
A water softener uses a mechanically driven control valve. During normal operation, this valve distributes the ow of raw (hard) water evenly over the
top of the media bed. As the hard water passes down through the media, hardness minerals -- primarily calcium, which exists in solution in a calcium
bicarbonate form -- are removed from solution and axed to the media. In place of this calcium, trace amounts of sodium ions are released. What was
calcium carbonate dissolved in the water becomes sodium bicarbonate (i.e., baking soda).
Once the resin has absorbed all the hardness minerals, and released all the sodium, that it can, regeneration is required. Regeneration is the process of
removing calcium/hardness minerals from the media and resetting it with fresh sodium ions. To achieve this, a piston in the softener control valve changes
position. The media is rst backwashed, to lift and unpack the bed. Next, it is bathed in a supersaturated brine (sodium chloride) solution. This bombards
the media with sodium ions, forcing the calcium/hardness minerals o and sending them down the drain. A relatively small percentage of sodium ions
remain on the media, though the majority pass to the drain as well. After this brine cycle, the media is rinsed o, the brine tank is relled, and the system
goes back into service.
When a single tank water softener regenerates, an internal bypass is opened in the control valve. This allows the facility to be served by hard water during
the regeneration period. Typically, this occurs in the middle of the night (2AM being the standard setting). Multi-tank systems regenerate one tank at a time,
with the non-regenerating tanks remaining online (with no periods of hard water being sent to the facility).
Many multi-tank commercial softening systems feature a Progressive Flow functionality. When building ow rates are low, only one tank is online/active.
As water usage increases, more and more units come online. Conversely, as usage decreases, tanks are progressively removed from service and put back
into standby mode. By bringing tanks on and oine, based on demand, we can maximize the softening capacity and eciency of the media in each tank.
The electronics in the control valves keep track of usage time for each individual tank. Tanks are rotated on and oine in a manner that equalizes usage
across all tanks over the course of 24 hours.
Another common option on larger commercial softening systems is Brine Reclamation, which utilizes an electronic control system and a 3-way motorized
valve to recycle a portion of the supersaturated brine (salt) water that is normally sent down the drain during regeneration. When the recycle interval ends,
the water eventually does go to drain. This ensures fresh brine for each new regeneration. By utilizing Brine Reclamation, a facility will normally see a salt
usage reduction of around 25%-35%, without any negative eects on softener capacity, eciency, or lifespan.

SOFTENER OPERATION
As water enters the softener, it passes over a resin bed in a special tank. The resin consists of tiny beads of a plastic called styrene. These beads attract and
hold sodium ions and exchange the sodium for hardness ions when encountered. Over time, the resin becomes saturated with hardness ions and no longer
removes hardness materials. The softener goes into a “regeneration” to ush hardness materials to the drain and refresh the resin with sodium. Regeneration
of single tank systems is typically programmed to take place in the middle of the night when little or no water is in use. Regeneration of individual tanks in
a multi-tank system occurs immediately (as needed), with the other tanks remaining online/ available.
REGENERATION CONSISTS OF FOUR CYCLES:
1. CYCLE: BACKWASH POSITION
Backwash is a rapid upward ow of water that loosens the resin bed and ushes iron particles, dirt and sediments ltered in the bed out to the drain.
2. CYCLE: BRINE DRAW / SLOW RINSE POSITION
Brine Draw is the process in which brine is drawn out of the brine cabinet and passed through the resin in a downward direction. This rinses the resin
and large amounts of sodium ions re- place the hardness ions accumulated during service.
Slow Rinse. After brine is completely removed from the brine cabinet into the resin tank the brine valve closes. Water replaces any remaining brine
from the resin, ushing hardness ions removed from the resin to drain.
3. CYCLE: FAST RINSE POSITION
Fast Rinse is a fast ow of water down through the resin tank that follows a Backwash. This ushes all remaining brine from the tank and packs the
resin bed for softening eciency.
4. CYCLE: BRINE FILL
Brine is water saturated with large amounts of a salt (sodium chloride). During Brine Fill, water ows into the salt storage area after each
regeneration and dissolves salt. During the regeneration process, hardness ions on the resin beads are replaced or exchanged for sodium ions from
the brine solution.
NOTE: SERVICE
When the softener is in service, normal operation is occurring. Water is owing through the softener and hardness minerals are being removed from
the water.

INSTALLATION PROCEDURES
1. IDENTIFY INSTALLATION LOCATION FOR WATER SOFTENER. Piping should be such that all hard water, except for outside hydrants, ows through
softener. This system and installation must comply with state and local laws and regulations.
2. CONNECT WATER PIPING. See install diagrams for plumbing layout. Important: Make all sweat-solder connections within 6 inches of softener before
applying threaded ttings. Overheating may cause damage to valve. Note: WCC recommends installing isolation valves on the inlet and outlet of each
control valve, as well as a full system bypass.
3. CONNECT DRAIN LINE. Be sure not to submerse drain line end into drain, as a 1-1/2” minimum air gap must be maintained to prevent potential
backow hazard. Firmly secure at drain, while maintaining a minimum 1-1/2” air gap. Note: Floor drain must be capable of handling full backwash
ow rate (see page 6 for backwash rates).
4. CONNECT BRINE LINE. Connect brine line (supplied in parts bag) to tting on brine tank, and on the control valve. Tighten both ttings with an
adjustable wrench. Note: If you have purchased a setup/startup service, startup agent will connect brine line on site.
5. INSTALL BRINE TANK OVERFLOW LINE. Install overow tting into hole inside of brine tank. An owner-supplied overow line should then be attached
and run to a nearby drain. Failure to run overow line could cause ooding and water damage should the brine tank overow. See the table below
for brine tank overow recommended line size. Note: Line sizes over 0.5 inches are to be hard plumbed to the drain.
6. CONNECT TO ELECTRICAL POWER SOURCE. Connect power cord to a separate 120v, 15-amp, ground fault interrupt (GFI) outlet. Note: Each control
valve should have a dedicated 120V outlet
NOTE: This system is not intended to be used for treating water that is microbiologically unsafe or of unknown quality without disinfection before or
after the system.
A vacuum break is required any time a vacuum situation may occur. This is common on wells, systems with booster pumps after the unit,
or when the system is installed in areas of varying altitudes. No warranty is considered if the system has been subjected to a vacuum. A
vacuum break should be installed between the softener and the potential cause of a vacuum.
