4. 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 1.5 to 2.5bar), adjust the regulator of the O2
supply inlet assembly to cause the reading on the test pressure gauge to reach 0.2 MPa
(namely, 2bar). For operations of the regulator, refer to section 5.3.2.4Adjust the
Regulator of the Pipeline Gas Supply Inlet Assembly.
5. Turn off the pipeline gas supply and bleed the residual pressure through O2 flushing.
6. Insert the pulled-out tube properly.
7. Pull out No.39 PU tube which connects the O2 supply inlet assembly to the O2
pipeline pressure gauge. The end of the tube which connects the O2 supply inlet
assembly is not pulled out but the other end is.
8. Connect the pulled-out tube end to the test pressure gauge, as shown below.
9. Turn on the pipeline gas supply and record the reading on the test pressure gauge. If
the difference between this reading and the reading on the O2 pipeline pressure gauge
is more than 0.1 MPa (1bar), it indicates that the O2 pipeline pressure gauge is
damaged. Handle this problem as described in the troubleshooting table.
10. Insert the pulled-out tube properly.
