ð With a bucket or hose, add approximately 15 liters of water to the brine tank.
If the tank has a salt platform in the bottom of the tank, add water until the water level is
approximately 25 mm (1") above the platform.
Info
Pentair recommends that recommend that you do not put salt into the tank before the
control valve has been started up. With no salt in the tank, it is much easier to view
water flow and motion.
6. Engage the refill cycle to prime the line between the brine tank and the valve (softener only).
ð Slowly open the main water supply valve again, to the fully open position. Be sure not to
open too rapidly as that would push the media out of the media tank.
ð Advance the controller to the Refill (C8) position. From cycle C1 (Backwash), press and
hold . This will display the current cycle.
While pressing , press to advance to the next cycle. Continue to advance through
each cycle until you have reached cycle C8 (Refill).
Info
As you advance through each cycle there will be a slight delay before you can advance
to the next cycle. The hourglass icon will be lit while the camshaft is indexing. There
may be a pause at cycle C4 (System Pause). This cycle allows the water/air pressure to
equalize on each side of the valve discs before moving on. The hourglass will not be
visible indicating that the system is paused.
ð With the water supply completely open, when the valve reaches C8 (Refill), the controller
will direct water down through the line to the brine tank. Let the water flow through the
line until all air bubbles have been purged from the line.
ð Do not let the water flow down the line to the tank for more than 1 to 2 minutes, or the
tank may overfill.
ð Once the air is purged from the line, press and simultaneously to advance to
cycle C0 (Treated Water) position.
7. Draw water from the brine tank.
ð From the treated water position (cycle C0), advance the valve to the draw brine position.
Press for 5 seconds.
ð The controller will begin a manual regen, and advance the control valve to the cycle C1
(Backwash). Press and to advance to cycle C2 (Draw).
ð With the controller in this position, check to see that the water in the brine tank is being
drawn out of the tank. The water level in the tank should recede very slowly.
ð Observe the water being drawn from the brine tank for at least 3 minutes. If the water
level does not recede, or goes up, check all hose connections. C2 should be displayed.
8. If the water level is receding from the brine tank you can then advance the controller back to
the treated water C0 position by pressing and simultaneously to advance the
controller to the C0 position.
9. Finally, turn on a faucet plumbed after the water softener. Run the faucet until the water runs
clear. Add salt to the brine tank.
