After installing a new spout assembly in the Healy 900 nozzle, which test must be conducted?

After installing a new spout assembly in the Healy 900 nozzle, conducting a nozzle dispensing shut-off test is essential to ensure that the nozzle functions correctly. This test verifies that the nozzle will automatically shut off when the fuel reaches the desired level in the tank, preventing spillage and ensuring safety during fuel dispensing operations.

The nozzle shut-off feature is critical for vapor recovery systems, as it helps to minimize the release of gasoline vapors into the environment, aligning with environmental compliance and safety regulations. If the nozzle does not shut off as designed, it could lead to overfilling and potential hazards, which is why this test is a standard procedure following the installation of new components.

While other tests, such as flow rate and pressure tests, may be relevant in different contexts, the shut-off functionality is crucial specifically following the installation of a spout assembly, making this the appropriate choice. Ensuring this feature works properly directly affects both operational safety and compliance with regulations governing vapor recovery systems.
