Initial Backwash
1
If days remaining is not already at 1 press and hold the Set/Change button. Now, press and hold
the set change button again, until the valve begins the backwash cycle and the display reads 1 –
10. Now, proceed to step two.
2
Start to put the valve into the service position by turning inlet the bypass knobs counter-
clockwise about a quarter inch, until you can hear water passing through the bypass into the
filter. Stop and wait until you see water coming out of the drain line. It will often be mixed with
air bubbles, but we will want to get all of that air out. When you do not see bubbles anymore,
keep opening the valve, a little bit at a time, stopping for a minute or two each time. You want to
see a corresponding increase in flow out of the drain line as you increase the flow of water into
the filter. After several minutes, you should have the valve fully open, and with no media
coming out. The water may appear milky white.

If possible 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 Tannin resin and prevent it from
cementing together.

Once the water is clear, press and hold the Set/Change button, and after 3 seconds the valve will
start to advance to the “Rinse” position. Once again, allow the water to flow for about five
minutes or until the water is clear.
5
Press and hold the Set/Change button advance to the “Service” position. 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.
Congratulations, you are done setting up your valve!
