About the water softener system

When the water softening system is providing soft water, it is called Service. During service, hard water flows from the house main water pipe into the water softening system. Inside the water softening system resin tank is a bed made up of thousands of tiny, plastic resin beads. As hard water passes through the bed, each bead attracts and holds the hard minerals. This is called ion-exchanging. It is much like a magnet attracting and holding metals. Water without hard minerals (soft water) flows from the water softening system and to the house pipes.

After a period of time, the resin beads become coated with hard minerals and they have to be cleaned. This cleaning is called recharge.

Recharge is started at 2:00 AM (factory setting) by the water softening system control, and consists of five stages or cycles. These are



During recharge the water softener is automatically put in bypass mode allowing hard water to be available to the home. Once the softener is recharged water is directed back through the softener to be conditioned.

However, you should avoid using HOT water because the water heater will fill with the hard water.

Salt dissolved in water is called brine. Brine is needed to clean the hard minerals from resin beads. To make the brine, water flows into the salt storage area during the fill stage.

During backwash, water travels up through

the resin tank at a fast flow rate, flushing accumulated iron, dirt and sediments from the resin bed and to the drain.


During brining, brine travels from the salt storage area into the resin tank. Brine is the cleaning agent needed to remove hard minerals from the resin beads. The hard minerals and brine are discharged to the drain.

Backwash is followed by a fast flow of water down through the resin tank. The fast flow flushes brine from the bottom of the tank, and packs the resin bed.

After fast rinse, the water softening system returns to soft water service.

The nozzle and venturi create a suction to move the brine, maintaining a very slow rate to get the best resin cleaning with the least salt.


After a pre-measured amount of brine is used, the brine valve closes. Water continues to flow in the same path as during brining, except for the discontinued brine flow. Hard minerals and brine flush from the resin tank to the drain.

About the water softener system


During normal operation, the present time of day and AM or PM and DAYS TO EMPTY show in the control display area.

The system will automatically recharge at the preset recharge time as needed.


Sometimes, a manually started recharge may be desired or needed. Two examples:


Touch (do not hold) the RECHARGE button.

RECHARGE TONIGHT flashes in the control display area. A recharge will occur at the next preset recharge start time. If you decide to cancel this recharge, touch the same button once more.

? You have used more water than usual

(house guests, extra washing, etc.) and you may run out of soft water before the next

? The system ran out of salt.


Press and hold the RECHARGE button until

RECHARGE NOW starts to flash in the control display area. The water softening system begins an immediate recharge and, when over in about two hours, you will have a new supply of soft water. Once started, you cannot cancel this recharge.

Use one of the following features to start a recharge immediately, or at the next preset recharge start time.


If electrical power to the water softening system is interrupted, the control display is blank, and the blue indicator light is off, but the control keeps correct time for 24 hours. When power is restored, you have to reset the present time only if the display and blue indicator light are flashing. All other settings are maintained and never require resetting unless a change is

If the time is flashing after a long power outage, the water softening system continues to work as it should to provide you with soft water.

However, recharge may occur at the wrong time of day until you reset the control to the correct time of day.


The control computer has a self-diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the control display.

About the water softener system


Colloidal and inorganically bound iron is of ferric or ferrous form that will not filter or exchange out of water. This water softener will not remove colloidal iron. In some instances, treatment may improve colloidal iron water.

Colloidal iron water usually has a yellow appearance when drawn. After standing for several hours, the color persists and the iron does not settle,but remains suspended in the

Iron in water can cause stains on clothing and plumbing fixtures. It can negatively affect the taste of food,drinking water, and other beverages. I
