5 WATER FLOW THROUGH THE SOFTENER IN FILL 11 SECTION 2 HOW YOUR WATER SOFTENER WORKS 2B. SOFT WATER SERVICE AND REGENERATION HT] 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 take brine from the salt tank and put it into the resin tank. They keep the brine flow down to a very slow rate to get the best resin cleaning with the least salt. [3 BRINE RINSE: After all of the brine goes into the resin tank, the brine valve closes. Water keeps flowing 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. FIG. 7 WATER FLOW THROUGH THE SOFTENER IN BACKWASH FIG. 6 WATER FLOW THROUGH THE SOFTENER IN BRINING AND BRINE RINSE 0 BACKWASH: During backwash, water flows UP through the resin tank (FIG. 7) at a fast rate to flush iron minerals, dirt and sediments from the bed and to the drain. The bed lifts and expands for good cleaning. [5]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. FIG. 8 WATER FLOW THROUGH THE SOFTENER IN FAST RINSE 12 SECTION 2 HOW YOUR WATER SOFTENER WORKS 2B. 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. The softener regenerates from 2:00 AM to about 4:00 AM, (you can change this time... see page 7), a time when not much water is used. If you get up early in the morning and you can hear the softener regenerating, change the time setting. Set the recharge time to 12:00 AM or 1:00 AM (page 7). Then regeneration will start and end that much earlier and your water heater will not refill with hard water if a hot faucet is opened. ELECTRONICS Two main parts of the softener’s electronics are T a WATER METER, and № a COMPUTER. T WATER METER — The water meter is in the softener valve outlet. As water flows through the meter, it sends electric pulses to the computer. The computer changes the pulses to a measure in gallons of water. № COMPUTER — The computer is part of the circuit board. It is programmed to know the softener’s capacity (how many grains of hardness minerals it will take out of the water before a regeneration is needed). When starting the softener, page 7, you set it for the grains per gallon (gpg) hardness of the water. To find a regeneration pattern best for your needs, the computer uses: (1) water usage from the meter, (2) hardness setting, (3) softener capacity, and (4) time since the last regeneration. The computer always adjusts this pattern to your water using habits. It works to provide you with soft water for the longest time, at the most efficient salt usage. Softening capacity is used as hard water goes through the softener and hardness minerals are removed. When the computer determines that only enough capacity remains to provide soft water up to the next regeneration starting time (2:00 AM, or as otherwise set), it will schedule a regeneration. RECHARGE TONIGHT displays until the regeneration begins. When the regeneration begins, TONIGHT goes off and RECHARGE NOW flashes during the 2 hour regeneration. 13 SECTION 3 CARE OF YOUR SOFTENER 3A. SALT...REFILLING STORAGE TANK/BREAKING A SALT BRIDGE WHEN TO REFILL WITH SALT: Check the salt level a few weeks after you install the softener and every week after that. Refill when the storage tank is about 1/3 full. Never let the softener use all the salt before refilling. Without salt, you will soon have hard water. IMPORTANT: You will have a loss in softening capacity and may get partly hard water if less than 10 inches of salt is in the storage tank. PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS. SALT BRIDGE Sometimes, a hard crust or salt bridge forms in the salt storage tank. It is usually caused by high humidity or the wrong kind of salt. When the salt bridges, an empty space forms between the water and salt. Then salt will not dissolve (melt) in the water to make brine. Without brine, the resin bed does not regenerate and you will have hard water. If the storage ...
