  • Page 7: Sanitizing The Water Softener

    Care is taken at the factory to keep your water softener clean and sanitary. Materials used to make the softener will not infect or contaminate your water supply, and will not cause bacteria to form or grow. However, during shipping, stor- age, installing and operating, bacteria could get into the softener.
  • Page 8: Fill The Storage Tank With Salt

    FILL THE STORAGE TANK WITH SALT Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is metered into the salt storage tank by the softener. However, you must keep the tank filled with salt.
  • Page 9: How Your Water Softener Works

    RECHARGE NOW — If you have guests visit- ing, or other times when you use more water than usual, you could begin to run out of soft water. If the softener is not scheduled to regener- ate for another day or 2, you would get hard water until then.

  • Page 12 SOFT WATER SERVICE AND REGENERATION 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.
  • Page 13 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.
