EXTRA RECHARGE Sometimes, a manually started regeneration (re- charge) may be desired, or needed. Two examples are: - - You have used more water than usual (guests visiting) and you may run out of soft water before the next timer started regeneration. - - You did not refill the softener with salt before it was gone.

SOFT WATER SERVICE AND REGENERATION AUTOMATIC BYPASS During the brining, brine rinse and backwash cycles of regeneration, HARD water goes through the softener valve and to the house pipes. If a faucet is opened, hard water is there for your needs. However, you should not use hot water, if possible, because the water heater will refill with hard water.
SALT¼ REFILLING STORAGE TANK/BREAKING A SALT BRIDGE WHEN TO REFILL WITH SALT (or potassium chloride): The Salt Monitor System (see page 10) will turn the low salt light on to warn you when to refill with salt. Check for a low salt light a few weeks after you install the softener, and every week after that.

If your water softener fails to work, make the following easy checks. Often, you will find what’ s wrong yourself and you won’ t have to call and wait for service. If you do not find anything wrong, while making the checks, and your softener still does not work, call your Sears Service Department.

Water flow is directed to the nozzle. Suction, created by the nozzle and venturi, draws brine from the salt storage tank and injects it into the resin bed via the bottom distributor.
