8. Turn on the pipeline N2O source and record the reading on the test pressure gauge. If
the difference between the readings of the test pressure gauge and N2O pipeline pressure
gauge exceeds 0.1 MPa (1 bar), the N2O pipeline pressure gauge is damaged. Handle
this problem according to the fault identification table.
9. Reconnect the pipeline to the pressure gauge. Reconnect pipeline 40.
III. Air supply inlet:
1. Turn off the pipeline gas source. Disconnect pipeline 50. Pull out the pipeline end that
connects to the system switch block.
2. Connect the 1 MPa test pressure gauge to the system switch by using the 3106-04-06
adapter connector and Y-shape connector 3140-06-00.
3. Turn on the pipeline air source. If the reading on the test pressure gauge is not within
0.2-0.25 MPa (2.0-2.5 bar), adjust the regulator to ensure that the reading on the test
pressure gauge is 0.2 MPa (2.0 bar). Record the reading on the air pipeline pressure
gauge.
4. Turn off the pipeline air source and turn on the air flow regulator to release the
remaining pressure.
5. Reconnect pipeline 50.
6. Disconnect PU tube 41 that connects the air supply inlet and the air pipeline pressure
gauge. Pull out the pipeline end that connects to the air supply inlet.
7. Connect the 1 Mpa test pressure gauge to the air supply outlet by using the 3106-04-06
adapter connector.
