Testing the Vacuum Pump
This test is not designed as a performance test for the measurement of negative
pressure. The test only indicates whether or not the vacuum pump is operational.
1. Check to be sure at least one port is opened into the container.
2. Press the Pause/Resume button.
3. Place a finger lightly over the suction openings (Fig. 9-4, (1)) and check
whether you can feel a sucking air flow.
Enter the results into the test log in section 16.1. The test is successfully complet-
ed when a stream of air can be demonstrated.
