Water filling, draining and watertightness inspection

7.1.1. System started

Once you have performed the previous initial programming steps, you will need to activate the
softener.
Caution
Do not rotate the camshaft by hand or damage to the unit may occur. Use the controller to
take the camshaft electronically through the cycles.
Follow these steps carefully:
1. Remove the cover from the valve. Removing the cover will allow you to see that the camshaft is
turning, and in which cycle the camshaft is currently positioned.
2. With the supply water for the system still turned off, position the bypass valve to the "non-
bypass" (normal operation) position.
3. Press on the controller for 5 seconds. This will initiate a manual regeneration.
The controller will indicate that the motor is turning the camshaft to cycle C1 (Backwash)
position by flashing an hourglass. The controller will display the total regen time remaining. If
you press and hold the
cycle.
4. Fill the media tank with water.
→ While the controller is in cycle C1 (Backwash), open the water supply valve very slowly to
approximately the ¼ open position.
Caution
If opened too rapidly or too far, media may be lost out of the tank into the valve or the
plumbing. In the ¼ open position, you should hear air slowly escaping from the valve drain
line.
→ When all of the air has been purged from the media tank (water begins to flow steadily from
the drain line), open the main supply valve all of the way. This will purge the final air from the
tank.
→ Allow water to drain out until the water runs clear from the drain line. This purges any refuse
from the media bed.
→ Turn off the water supply and let the system stand for about 5 minutes. This will allow any
trapped air to escape from the tank.
