Plumbing the Check Valve Assembly
Connecting the Check Valve Assembly
Install tube adapter on the injector.
Connect the check valve assembly tubing that is closest to the check valve to the tube adapter on the injector.
Attach the other tubing end of the check valve assembly to the ozone outlet barb on the DEL AOP 25.
Below Water Line Installation
If the DEL AOP 25 must be mounted below the water line, the check valve assembly tubing must be run to a point above the water line.
This will prevent water from running back to the DEL AOP 25 when the pool pump is not running, and provides protection in the event of a failed check valve.
