3. Turn on N2O and O2 pipeline supplies. Adjust the regulator of the N2O supply inlet assembly to
the same value as measured/set for the O2 supply inlet assembly (see step 4 of O2 supply inlet
assembly) Record the reading on the N2O pipeline pressure gauge.
4. Turn off N2O pipeline supply and bleed the residual pressure by opening the N2O flow
regulator.
5. Reconnect tube 49.
6. Pull out No.40 PU tube which connects the N2O supply inlet assembly to the N2O pipeline
pressure gauge. Remove the tube end which connects N2O supply inlet assembly.
7. Connect 1MPa test pressure gauge to the outlet of N2O supply inlet assembly through “3106-
04-06 adapter connector”.

8. Turn on the N2O pipeline supply and record the reading on the test pressure gauge. If the
difference between this reading and the reading on the N2O pipeline pressure gauge is more
than 0.1 MPa (1bar), it indicates that the N2O pipeline pressure gauge is damaged. Handle this
problem as described in the troubleshooting table.
9. Reconnect tubing to pressure gauge. Reconnect tube 40.
