  • Page 15: Installing The Bypasses

    System assembly | 3.5 Installing the bypasses There are two openings with external threads and arrows indicating the water inlet and outlet at the back of the central control valve. The bypass mounts to these threads for both central control valves. The swivel nut only needs to be tightened by hand, as the O-ring ensures the joint is tight.

Image 7 Vertical adapter. 3.7 Installing the motor alternating valve The motor alternating valve (MAV) screws to the vertical adapter (Image see item 3.4)

  • Page 17: Installing The Water Inlet Pp Pipe

    System assembly | The MAV is used to shut off the water flow from the regenerating central control valve and redirect the water flow from the central control valve supplying treated water to the outlet. You will see a thread inside the transparent dome at the top of the MAV. When water flows through inlet B to the outlet, the thread will not be visible in the transparent dome (retracted), when water flows through inlet A to the outlet, the thread will be visible (extended).

  • Page 18: Connecting The Brine Hoses

    | 3.11 Connecting the brine hoses 3.11 Connecting the brine hoses Brine hoses (semi-transparent, 9.5 mm diameter) connect the two control valves to the brine valve on the brine tank. Both control valves therefore have a brine hose running to a T-piece, from which a brine hose runs to the brine valve.

  • Page 19: Connecting The Wastewater Lines

    System assembly | NOTE Use a kink-proof plastic hose as the brine hose from the brine tank to the central • control valve. Secure the brine hose against moving. • Keep the brine line as short as possible. • Avoid any cross-section constriction. •...

  • Page 20: Connecting The Two Control Valves

    | 4.1 Connecting the two control valves If the wastewater connection is so far from the desired installation site that the included drain hose is not long enough, please use a longer hose of the same diameter or extend the included hose accordingly. You can also order the required drain hose length by the metre from your water softener dealer.

  • Page 35: Non-Stop Operation

    Commissioning | However, if the user wishes to regenerate both pressure tanks, it’s important to note it takes 4 hours for saturated brine to form in the brine tank. You must wait this long before regenerating the first pressure tank after adding water and regenerating salt to the brine tank before regenerating.

  • Page 36: Water Softener Operating Cycles

    | 7.1 Operation (non-stop operation) 7 Water softener operating cycles 7.1 Operation (non-stop operation) Untreated water flows through the central control valve and into the pressure tank. The pressure tank is filled with exchanger resin for ion exchange. The untreated water flows through the resin bed from top to bottom.

  • Page 37: Brine (Resin Bed Regeneration)

    Water softener operating cycles | Image 20. Operating cycles of softener backwashing 7.3 Brine (resin bed regeneration) The central control valve takes concentrated brine in the brine tank in through the sole valve via a Venturi nozzle (injector). The brine mixed with the motive water in the Venturi nozzle flows through the exchanger resin from the bottom up.

  • Page 38: Fast Rinse

    | 7.4 Fast rinse 7.4 Fast rinse After salting and the slow rinse, the resin bed is flushed with water at a higher speed from above to ensure there is no regenerating salt remaining in the resin bed. This process is also referred to as rinsing. Image 22.
