Info
This chapter is available for standard regeneration flows. Contact your supplier if the
actual regeneration is not standard and if you need assistance.
7.1 Water filling, draining and waterproofness inspection
7.1.1 Activating a single valve system (System 4)
1. With the bypass still in Bypass position (inlet and outlet of the valve closed), plug in the NXT/
NXT2 controller to the power source.
2. Proceed to programming according to system specification if not done yet.
3. Start a manual regeneration by pressing the regen button for 5 seconds. The piston will move
into backwash position. Once in this position, unplug the NXT/NXT2 controller from the power
source.
4. With the outlet manual valve still closed, slowly open the inlet manual valve. The valve and
tank will slowly get filled with raw water, allowing air to be purged by the drain. Open the inlet
progressively until fully open position.
5. Once the drain runs clear and the inlet manual valve fully open, plug in again the NXT/NXT2
controller to the power source.
6. Push on the regen button once to move the piston to the next regeneration cycle position.
Leave the valve 1 minute in each position and move to the next one, until C4 or Cycle 4/5 is
displayed. When C4 or Cycle 4/5 is displayed, let the valve run the entire cycle and check the
level of water in the brine tank. The level of water in the brine tank should be about 5 cm
above the salt platform. You may want to mark the level on the brine tank as this can be used
as an indicator for the future lifetime of the softener.
7. Once C4 or Cycle 4/5 is completed, the valve will automatically go back into service position
(unless non-standard regen sequence is programmed). Start again a manual regeneration by
pressing for 5 seconds on the regen button. The valve will move to backwash position.
8. Press the regen button once to move to brine draw position. Check to see in the brine tank if
the water level decreases.
9. Once the draw function is observed and confirmed (level of water in the brine tank has
decreased), you may go through each cycle pushing on the regen button until C4 or Cycle 4/5,
leave the water come back to the 'full' level, and then push on the regen button so that the
valve returns into service position.
10. Slowly open the outlet manual valve, and close the bypass manual valve. The system is now in
service.
11. Fill the brine tank with salt. You may want to mark the level of water in the brine tank when
completely refilled with water and full of salt. In the future, after each regeneration, you can
visually control that the quantity of water refilled should be between the 2 marks done.
Marking are optional, but may allow to visually detect a irregularity during regeneration that
may lead to softener inefficiency.
