9. Turn on the pipeline gas source and record the reading on the test pressure gauge. If the
deviation between the readings of the test pressure gauge and O2 pipeline pressure
gauge exceeds 0.1 MPa (1 bar), the O2 pipeline pressure gauge is damaged. Handle this
problem according to the fault identification table.
10. Reconnect pipeline 39.
For details about the PU tube numbers, see relevant sections.
II. N2O supply inlet:
1. Turn off the pipeline gas source. Turn on the needle valve to release the remaining
pressure and then turn off the needle valve. Disconnect pipeline 48. Pull out the pipeline
end that connects to the O2/N2O block valve and do not pull out the other end.
2. Connect the 1 MPa test pressure gauge, the removed end of pipeline 48, and the inlet of
the O2/N2O block valve by using the Y-shape connector 3140-04-00.
