5. Add water to the brine tank (initial fill) (softener and 3-cycle filters only).
→ With a bucket or hose, add approximately 15 liters (4 gallons) 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.
Note
We 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).
→ 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.
→ Advance the controller to the Refill (C8) position. From cycle C1 (Backwash), press and hold
. This will display the current cycle.
While pressing
each cycle until you have reached cycle C8 (Refill).
Note
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.
→ 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.
→ Do not let the water flow down the line to the tank for more than 1 to 2 minutes, or the tank
may overfill.
→ Once the air is purged from the line, press
(Treated Water) position.
7. Draw water from the brine tank.
→ From the treated water position (cycle C0), advance the valve to the draw brine position. Press
for 5 seconds.
The controller will begin a manual regen, and advance the control valve to the cycle C1
(Backwash). Press
→ 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.
→ 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
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.
