EZ]BRINING: During brining, the brine is moved from the salt storage area, into the resin tank. Inside

the resin tank, brine cleans hardness minerals from

the resin beads and they are discharged out the

drain. How much brine is needed to clean the resin

depends on:

--the amount of resin in the softener,

--how fast the brine goes through the bed.

The nozzle and venturi (FIG. 6) make suction to move brine from the salt tank into the resin tank.

get the best resin cleaning with the least salt.

[] BRINE RINSE: After all of the brine is sucked OUt of the salt tank, the brine valve closes. Water keeps

flowing through the resin tank the same way it did

during brining except the brine flow has stopped.

Hardness minerals and brine flush from the resin tank to the drain. Brining and brine rinse together vary in length of time they take, relative to the fill cycle length.

E_]FAST RINSE: Backwash is followed by a fast flow of water down through the resin tank. The fast flow packs the resin bed and gets it ready for return to service (FIG. 8).

After fast rinse, the softener returns tO service. Hard water goes into the resin tank where the resin bed

again takes out the hardness minerals. Soft water goes to the house soft water pipes.
