12. Now you can slowly turn the bypass valve to the service position. First, partially open the Inlet side of the
bypass valve so the tank fills slowly. Second slowly open the Outlet side of the bypass until it is in the full service
position. Once the tank is full of water and is coming out of the drain you can fully open the inlet side of the
bypass valve.
13. There should be no media coming out of the drain line, but the water may be turbid and dirty looking. You
do not want to see a large amount of media coming out, which would mean you have very high water pressure,
or the drain flow for the controller is missing. Leave the controller in backwash as long as it takes for the water
to run clear. Once clear you can plug the controller back in and let it finish the backwash and the rest of the
regeneration. After filter has been regenerating for 20 minutes, look inside the brine tank, and you should see
that the brine tank is empty. At the end of the regeneration check to make sure that the filter has added water
to the brine tank to make brine for the next regeneration cycle. The regeneration takes approx. 11/2 hours.
14. If possible verify that the backwash flow rate is correct. The recommended backwash flow rate for 1.0 cubic
foot and 11/ 2 cubic foot is 2.2 gallons per minute. 2 cubic foot is 3.2 gallons per minute. 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 regenerate the media. It is recommended that you do 2 – 3 regenerations when the
conditioner is new so that the media gets fully charged.
