    Lync WQ-SF SECTION 3: Operation Water Softener Down-Flow Brining Diagram 3.11. 1 - Service Position: Hard water enters unit from the valve inlet and flows down through the minerals. The softened water enters the center tube from the bottom distributor and flows up. It flows around the piston and exits the system from the valve outlet.
  • Page 38 Lync WQ-SF SECTION 3: Operation 2 – Backwash Position: Hard water enters the unit from the valve inlet and flows through the regenerating valve. It flows down the center tube and flows up the tank through the minerals. The water flows around the piston and goes to the drain line.
  • Page 39 Lync WQ-SF SECTION 3: Operation 3- Brine Position: Hard water enters the unit from the valve inlet and flows up into the injector housing and down through the nozzle and orifice to draw brine from the brine tank. Brine solution flows down through the minerals and enters the center tube from the bottom distributor and flows up through the center tube.
  • Page 40 Lync WQ-SF SECTION 3: Operation 4- Slow Rinse Position: Hard water enters the unit from the valve inlet, flows up into injector housing and down through the nozzle and orifice. Hard water flows around the piston and flows down through the minerals and from there, it flows up from the center tube. Water flows around the piston and leaves the unit through the drain line.
  • Page 41 Lync WQ-SF SECTION 3: Operation 5- Rapid Rinse Position: Hard water enters from the valve inlet and flows thru the regenerating valve. It directly flows down through the minerals and flows up from the center tube. The water flows around the piston and leaves the unit from the drain line.
  • Page 42 Lync WQ-SF SECTION 3: Operation 6- Brine Tank Fill Position: Hard water enters from the valve inlet and flows through the service valve. Hard water flows down through the minerals and after getting conditioned, it enters the bottom distributor and flows up the center tube. The soft water flows around the piston and leaves the system through the valve outlet.
