NOTE:
If you are replacing a CUNO Aqua Pure Membrane with an Pentair Membrane, you will need to remove the Red Stealth Flow Control tube (SFC) and replace it with a length of 1/4" tubing. The Pentair Membrane has its own internal check valve and an internal flow control.

To remove the Red SFC Tube:

Remove the existing encapsulated membrane module with the Red SFC Flow Control Tube and replace with the Pentair Encapsulated Membrane with the Check Valve and Flow Control.

Discard the Red SFC tubing from the old membrane and replace with a section of 1/4" tubing into the drain port.
