Info
This chapter is available for standard regeneration types. 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)
a) With the bypass still in Bypass position (inlet and outlet of the valve closed), plug in
the NXT/NXT2 controller to the power source.
b) Proceed to programming according to system specification if not done yet.
c) 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.
d) 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 let progressively until fully open position.
e) Once the drain runs clear and the inlet manual valve fully open, plug in again the
NXT/NXT2 controller to the power source.
f) 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.
g) Once C5 or Cycle 5/5 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.
h) Press the regen button once to move to brine draw position. Check to see in the
brine tank if the water level decreases.
i) 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
C5 or Cycle 5/5, leave the water come back to the 'full' level, and then push on the
regen button so that the valve returns into service position.
j) Slowly open the outlet manual valve, and close the bypass manual valve. The
system is now in service.
k) 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.
