Quick Cycling - Pentair Riversoft Installer Manual

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.
→ Unplug the power transformer from the socket so that the valve remains in backwash
position.
→ When most 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 remaining air
trapped in the tank.
→ Allow water to drain out until the water runs clear from the drain line. This also purges any
debris resulting from installation and piping work from the media bed.
→ Turn off the water supply and let the system stand for about 5 minutes. This will allow any still
trapped air to escape from the tank.
→ Turn the water on again and plug the power transformer back into its electrical socket.
NOTE

Do not put salt into the tank before the valve has been started up. With no salt in the tank, it
is much easier to view water flow and motion.

6.1.2. Quick cycling

1. Quick cycle the valve until C7 (refill cycle) by pressing
valve in refill position to prime the line between the brine tank and the valve.
NOTE

As you advance through each cycle there will be a slight delay before you can advance to the
next cycle. There may be a pause at cycle C3 (System Pause). This cycle allows the water/
air pressure to equalize on each side of the valve discs before moving on.
→ With the water supply still completely open, let the water flow through the line until the end of
C7 (refill cycle) so that all air bubbles have been purged from the line and the required water
for 1st brine preparation is in the brine tank already.
→ Mark the level of water in the brine tank.
→ Once the air is purged from the line, press
(Treated Water) position.
