Cylinder test
CAUTION To prevent damage to the system, open the cylinder
valves slowly and do not force the flow controls.
WARNING Do not leave gas cylinder valves open if the pipeline
supply is in use. Cylinder supplies could be depleted,
leaving an insufficient reserve supply in case of pipeline
failure.
1. Disconnect the pipeline supplies and close all cylinder valves.
2. If the pipeline and cylinder pressure gauges are not at zero:
• Connect an O2 supply.
• Set the System switch to On.
• Set the flow controls to mid range.
• Make sure that all of the gauges except for O2 go to zero.
• Disconnect the O2 supply.
• Make sure that the O2 gauge goes to zero. As the pressure
decreases, the alarms for O2 supply failure should occur.
3. Make sure that the cylinders are full.
• Open each cylinder valve.
• Make sure that each cylinder has sufficient pressure.
• If the cylinder does not have sufficient pressure, close the
cylinder valve and install a full cylinder.
4. Set the System switch to Standby.
5. Turn off the auxiliary O2 flowmeter (if equipped).
6. Turn off the suction (if equipped).
7. Test one cylinder at a time for high-pressure leaks.
• Open the cylinder.
• Note the cylinder pressure.
• Close the cylinder valve.
• Wait for one minute and record the cylinder pressure again.
• If the cylinder pressure for Air or O2 decreases more than
690 kPa (100 psi), there is a leak.
• If the cylinder pressure for N2O decreases more than
690 kPa (100 psi), there is a leak.
