This menu item is for the number of minutes for the Fast (or Rapid) Rinse. The
default is 10 minutes. Press the menu/confirm button, the 10 will flash; adjust it down

Carbon (Carbon media) and different types of Iron Removal media (Pro-Ox, Mang-Ox, Katalox

Initial Backwash:
1
After programming, the system must be run through an initial backwash.
2
Close inlet valve B and outlet valve C, and open the bypass valve A. From the initial valve
menu, press the Manual/Return button to enter into the backwashing. When the backwash
icon is displayed, slowly open the inlet valve B to a quarter position to make the water flow
into the resin tank; you should be able to hear the sound of air escaping from the drain
pipeline. After all the air is out of the pipeline, open inlet valve B and clean the foreign
materials in the tank until the water is clean.
3
Verify that the backwash flow corresponds with the size of your system below. You can
easily run the drain hose to a bucket and using a watch verify the flow rate in gallons per
minute. An adequate backwash is critical to properly clean the Carbon media and prevent it
from fouling or channeling.
