There is air expelling out of my AirMini tube. Is my tube leaking?

When the system is correctly assembled, airflow will be felt from the ActiveAir vents in either the Vent
Module (N20 connector, P10 for AirMini) or from the F20 connector elbow as shown in Figure 1.

If this is not the location of the leak, it is possible that the tubing is not assembled (or connected) correctly. Check correct tubing assembly in the user guide instructions.
