WHY IS THERE NO GAS FLOW?

1. The injector is not supplying adequate suction.

• Check the pool pump and ensure water is flowing through the Injector.
• Check to ensure that the pump skimmer and filter are clean.
• Check to ensure that the Injector is plumbed in the right direction.
• Ensure that there is no debris clogged inside the Injector.

2. The tubing is impaired.

• Check for kinks or clogs.
• Check for cracks or cuts.
• Check connections.
• Ensure that the Check Valve is installed with the arrow pointing towards the Injector.
• Be sure that the Check Valve has not become fouled with debris. Disconnect the Check Valve Assembly from the Tube Adapter on the Injector. With the pump running, test the end of the Tube Adapter 15 DEL AOP S Installation & Operations Manual with your thumb, and feel for suction. Wash your hands immediately afterwards to remove any residual nitric acid. If there is sufficient suction without the Check Valve Assembly connected, replace the Check Valve Assembly.
