a. If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tubing, or brine valve riser pipe. CYCLE FLOW RATES (GALLONS PER MIN.) FILL (flow to salt storage tank) 0.3 (1.1 liters) BRINING .19 (.7 liters) BRINE RINSE .12 (.45 liters) BACKWASH (flow to drain) ) 2.0 (7.6 liters) ( FAST RINSE 2.0 (7.6 liters) 2. After observing fill, press the ON/OFF-HOLD button to move the softener into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liquid level. NOTE: Be sure a salt bridge is not preventing water with salt contact. a. If the softener does not draw brine. . nozzle and/or venturi dirty or defective. . nozzle and venturi not seated properly on gasket. . restricted drain (check drain fitting and hose). . defective nozzle and venturi seal. . other inner valve defect (rotor seal, rotor & disc, wave washer, etc.). NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw. 3. Again press ON/OFF-HOLD to move the softener into backwash. Look for a fast flow of water from the drain hose. a. An obstructed flow indicates a plugged top distributor, backwash flow plug, or drain hose. 4. Press ON/OFF-HOLD to move the softener into fast rinse. Again look for a fast drain flow. Allow the softener to rinse for a few minutes to flush out any brine that may remain in the resin tank from the brining cycle test. 5. To return the softener to service, press ON/OFF-HOLD. 23 SECTION 5 ECTION 5 SERVICE TECH. INFORMATION 5B. ROTARY VALVE SERVICE Before working on the valve, turn off the water supply and disconnect from electrical power. TO RELIEVE PRESSURE: - --- --3 VALVE BYPASS: Close the inlet valve and open a soft water faucet. Then close the outlet valve and open the bypass valve. - --- --SEARS SPECIAL BYPASS: Slide the bypass valve stem to bypass position. Loosen the 3 hex head screws (see A in drawing) toward the back side of the valve to allow pressure water to bleed out Catch water with a rag. DISASSEMBLY To remove a part or group of parts, refer to the valve drawing. A common screwdriver or nut driver, Phillips screwdriver and pliers are the only tools needed to completely disassemble. SERVICING THE VALVE Inspect all o-rings, seals and gaskets for wear or defects. Inspect the bottom surface of the rotor and disc for scratches, chips or wear. NOTE: If replacement is needed, be sure to use the current replacement part. ASSEMBLY Be sure all parts are in place and in the proper position. Lubricate ALL o-rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-section). Apply a light coating of silicone grease to the seal’s crossing ribs. Then, carefully center the wear strip on the seal, and push it downward onto the seal. Install the nozzle and venturi seal and drain seal. Assemble 2 o-rings and the wave washer onto the rotor and disc. Then center the rotor and disc, in the valve body, on the rotor seal. Lower the cover onto the valve body and rotor shaft. Then install the cover holding screws. Before tightening the screws, install the valve cam and gear. Then, turn the rotor (clockwise only) to service position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds. Lubricate the gear on the motor, and the valve cam gear with Molykote grease, or other high quality gear lubricant. Be sure to orient switch as shown, with lever toward the cam. 24 SECTION 5 ECTION 5 SERVICE TECH INFORMATION 5C .. WATER FLOW THROUGH THE SOFTENER VALVE SERVICE CYCLE Hard water enters the valve inlet port. Internal valve porting routes the water down and out the top distributor, into the resin tank. Hard water is softened as it passes through the resin bed, then enters the bottom distributor. Soft water flows back into the valve and out the valve outlet, to the house soft water pipes. FILL CYCLE To begin a regeneration, the electroic timer energizes the circuit to the valve motor. The valve motor rotates the rotor and disc and the valve cam until the position switch lever drops, to open the motor circuit and position the valve in FILL. As the rotor and disc rotates, the port opens for SOFT water fill through the venturi. Fill flow continues to the brine valve, and into the salt storage tank. Soft water is still available to the house lines. 25 SECTION 5 ECTION 5 SERVICE TECH. INFORMATION 5C. WATER FLOW THROUGH THE SOFTENER VALVE BRINING AND BRINE RINSE CYCLES After fill, timer/switch action allows the motor to turn the rotor and disc into BRINING position. 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. Flow continues out the top distributor and to the drain. Ha...
