Commissioning
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
1. With the bypass still in bypass position (inlet and outlet of the valve closed), plug in the SXT
controller to the power source.
2. Proceed to programming according to your 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. If the first cycle is not backwash, quick cycle the valve until the piston
is in backwash position. Once in this position, unplug the SXT controller from the power
source.
4. With the bypass still in bypass position, open the nearest faucet close to the system.
5. Put the bypass slowly in service position. The valve and tank will slowly get filled with raw
water, allowing air to be purged by the drain and/or by the open faucet next to the system.
Open the inlet progressively until fully open position.
6. Once the drain runs clear and the bypass valve is fully in service position, plug in again the
SXT controller to the power source.
7. Push on the regen button once to move the piston to the next regeneration cycle position.
Leave the valve 1 minute in each positions and move to the next one, until refill cycle is
displayed. When refill cycle is displayed, let the valve run the entire cycle and check the level
of water in the brine tank or cabinet. 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.
8. Once refill cycle 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.
9. Press the regen button once to move to brine draw position. Check to see in the brine tank if
the water level decreases.
10. Once the draw function is observed and confirmed (level of water in the brine tank or cabinet
has decreased), you may go through each cycle pushing on the regen button until refill cycle,
leave the water come back to the "full" level, and then push on the regen button so that the
valve returns into service position.
11. Fill the brine tank or cabinet with salt. You may want to mark the level of water in the brine
tank/cabinet 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 detecting any irregularity
during regeneration that may lead to softener inefficiency.
12. With the brine tank completely refilled and full of salt, adjust the safety brine valve in the
brine well. Make sure the overflow elbow is installed above the float level.
13. After the softener has been running a few minutes in service, proceed to hardness test on
outlet water to make sure the water is treated as per requirements.
