10. Switch on the pipeline source and record the reading on the pressure gauge. If the
deviation between this reading and the reading on the O2 pipeline pressure gauge
exceeds 0.1 MPa (1 bar), the O2 pipeline pressure gauge is damaged. Handle this issue
according to the fault locating table.
11. Reconnect pipeline 39.
NOTE
For the number of PU tubes, refer to the corresponding description in section 9.5.2
Pneumatic Connections.
II. N2O inlet assembly
1. Stop the gas supply. Disconnect pipeline 49 connecting to the EFCS flowmeter.
2. Connect pipeline 49 to the 1 MPa test pressure gauge.
3. Switch on the N2O and O2 sources. Record the reading on the pressure gauge. If the
deviation between this reading and the reading on the N2O pipeline pressure gauge
exceeds 0.1 MPa (1 bar), the N2O pipeline pressure gauge is damaged. Handle this issue
according to the fault locating table.
4. Switch off the N2O source.
5. Reconnect pipeline 49.
