5. Add water to the brine tank (initial fill) (softener 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. 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.
→ 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.
Note
Proceed as previously mentioned taking into account the regeneration sequence described
in chapter 3.6. Regeneration Sequence for Twin and Lockout Systems, page 21.
→ Once the air is purged from the line, press
(Treated Water) position.
