7.1. Water filling, draining and waterproofness inspection
7.1.1. Activating the softener
A With the bypass still in bypass position (inlet and outlet of the valve closed), plug in the SXT
controller to the power source.
B Proceed to programming according to your system specification if not done yet.
C Start a manual regeneration by pressing the regen button for 5 seconds. The piston will move in
backwash position. If first cycle is not backwash, quick cycle the valve until the piston reach
backwash position. Once in this position, unplug the SXT 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 manual
valve progressively until fully open position.
E Once the drain runs clear and the inlet manual valve fully open, plug in again the SXT controller
to the power source.
F Push on the regen button once to move the valve piston to the next regeneration cycle position.
Leave the valve 1 minute in each position and move to the next one, until refill cycle is reached.
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 refill cycle is completed, quick cycle the valve into service position. Start again a manual
regeneration by pressing for 5 seconds on the regen button. Quick cycle the valve to backwash
position.
H Press the regen button to move to brine draw position. Check to see in the brine tank if the water
level decrease.
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 BF, 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.
