3. Turn on O2 pipeline supply and record the reading on the O2 pipeline pressure gauge. Observe
the test pressure gauge. If the reading on the test pressure gauge is not within the range of 0.15
to 0.25 MPa (namely 22.7 to 36.3 psi), adjust the regulator of the O2 supply inlet assembly to
cause the reading on the test pressure gauge to reach 0.2 MPa (namely, 39 pai). For operations of
the regulator, refer to ‘‘Adjust the Regulator of the Pipeline Gas Supply Inlet Assembly’’ on page
5-40.
4. Turn off the pipeline gas supply and bleed the residual pressure through O2 flushing.
5. Reconnect tube 57.
6. Disconnect tube 39 which connects the O2 supply inlet assembly to the O2 pipeline pressure
gauge. Remove the end of tube to the O2 supply inlet assembly.
7. Connect 1MPa test pressure gauge to the outlet of O2 supply inlet assembly through “3106-04-
06 adapter connector”.
