is a good setting. Press the down button again to proceed.
i. Step 7: BRINE—this stands for Brine Draw. This does not apply to an iron filter, so lower this
setting to the absolute minimum value, which is 3. The display should read 3 MIN, meaning the
cycle will be 3 minutes long. Press the down button to proceed.
j. Step 8: RINSE—this is the rapid rinse cycle, and should be set to 10 MIN. Press the down button
to proceed.
k. Step 9: REFILL—This does not apply to an iron filter, so lower this setting all the way down to
00.0. When it is properly set, it should display 00.0 MIN. Press the

17. Now you can start the initial manual backwash. Turn the manual knob clockwise to “BA. WA” and a
manual backwash will begin.

open the valve all the way. You want to allow all of the
air in the tank to escape before allowing the water to flow freely.
19. Once water begins to flow from the drain line, open the inlet valve all the way. Continue to let the wa‐
ter run from the drain line until there are no longer any media fines present. This may take 1-2 back‐
wash cycles.
20. If possible, verify that the backwash flow is 5 gallons per minute for the 1.0 cubic foot and 7 gallons per
minute for the 1.5 cubic foot. 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 cleaning the Pro-OX
media and preventing it from cementing together.
21. Next, open the outlet on the bypass valve and then open the nearest treated water faucet to the unit
and allow the water to run until it is clear. We advise using a bathtub, laundry sink, or other fixture
that does not have an aerator screen, as any remaining residue may get caught in the screen.
