4.3 Functional Checks
The eAdvantage® is equipped with an internal self-diagnostic test system to
ensure the device's full functionality. During this phase, the valves and sensors
undergo a check (refer to section 5.1). While this test is optional, a functional
check can be performed by following the next steps.
Along with the contents of the shipping cartons you will require the following
items to enable you to undertake the functional check.
1. Nitrous oxide and oxygen pressure sources with 50-70 PSI output capable
of providing a minimum of 100 L/min at no less than 45 PSI (3.1 Bar).
2. Vacuum generator with a minimum 30 L/min fl ow rate.

4.3.1. Input Leak test

After securely connecting the supply hoses to the device (see section 4.2.3 for hose
connection guidance). Then, proceed by opening the N2O and O2 gas sources.
Observe for any signs of leakage. If a leak is detected, tighten the connections.
Note:
When attaching connections, ensure they are 'fi nger tight' only. Avoid
using tools or excessive force, as this can lead to over-tightening and potential
damage to the connections.

4.3.2. Output Leak test

The eAdvantage® is equipped with an automatic leak detection feature that alerts
the user to any detected leaks inside the device. Alternatively, you can manually
perform the Output Leak Test.
To conduct the test, connect and turn ON both gases. Attach a closed system
pressure gauge to the gas output port; the pressure should not increase by more
than 2 cmH2O in 10 seconds.
Testing of the Individual Features of eAdvantage® System
Various features of the eAdvantage® system can be individually tested or measured.
This is done using a calibrated pressure gauge and fl ow-meter as part of the optional
functional checks:
