Regenerating The System Section 6.4
- Once the media is fully saturated, the actual unit regeneration can occur. With the unit still
in the backwash position, slowly start opening the inlet isolation valve. If the unit still has
any air inside, it will sputter out. Constantly check the drain water and ensure only fines
from the media bed is being backwashed out. If the drain water contains more than fines,
reduce the backwash flowrate by throttling the inlet isolation valve. Any traces of air in the
media bed can result in backwash the media out. If this is occurring, close the inlet isolation
valve and allow the media to soak a little longer. Later, gradually fully open the inlet isolation
valve. The backwash flow controller will limit the flow to drain. Allow the unit to backwash
until the waste water clears up and there is no colour or fines still being removed. This pro-
cess may take 20 minutes or more. Once completed, close the inlet isolation valve.
- With the inlet still closed, plug the unit back in. The valve may cycle back to the home
position. If so initiate a regeneration again by pressing the SET button on the valve.
- Check all steps in the regeneration cycles and confirm the system is operating as
intended.
- Ensure that in the brine draw cycle, brine is being drawn from the brine tank. If you con-
tinually see air bubbles in the brine line, recheck the brine tank connections and ensure they
are properly sealed. Confirm the brine tank safety float is not restricted from moving .
- In the brine tank refill position, confirm the brine tank is being refilled properly. Confirm
the brine tank safety float is not restricted from moving and operating properly.
- Upon completion of the steps above, the unit outlet isolation valves are slowly opened.
-The system bypass valve should then be closed. The system and piping should now be
properly flushed. After this the system is now ready for normal service operation.
- Test the service water and confirm the system is operating properly.
