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 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 Chemsorb media
and prevent it from cementing together.
