SECTION 2 HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

REGENERATIONSERVICE

When the softener is giving you soft water, it is

called "Service". During service, hard water comes

from the house main water pipe into the softener.

Inside the softener resin tank is a bed made up of

thousands of tiny, plastic resin beads (FIG. 5). As

hard water passes through the bed, each bead at

tracts and holds the hardness minerals. This is

called ion-exchanging. Water without the hardness

minerals (soft water) flows out of the softener and

into the house soft water pipes.After a period of

time, the resin beads hold all of the hardness miner

als they can, and cleaning with salt brine is needed.

This cleaning is called regeneration or recharge. Re

generation is started at 2:00 a.m. by the electronic

timer (see page 2-6). It takes place in 5 stages or

cycles. These are:

D FILL B BACKWASH

B BRINING

B BRINE RINSE

FAST RINSE

Note:

If the Clean feature is set to ON, additional back

wash and fast rinse cycles occur before the fill cycle.

n FILL: Salt, dissolved in water, is called brine.

Brine is needed to clean the hardness minerals from

the resin beads. To make the brine, water flows into

the salt storage area during the fill stage as shown

in FIG. 6. Fill cycle length depends on how much

soft water making capacity you have used since the

last regeneration. As you use more water, fill time

increases so more brine is made. The greater

amount of brine cleans more hardness minerals

from the resin bed.
