To prevent damage:
• Open the cylinder valve slowly.
• Do not force the flow controls.
If your system does not use cylinder supplies, do not do steps 3 and
5.
1. Set the system switch to On.
2. Disconnect the pipeline supplies and close all cylinder valves (if
equipped). If the pipeline and the cylinder pressure gauges are
not at zero, bleed all gases from the system.
• Connect an O
• Set the flow controls to mid range.
• Make sure that all gauges but O
• Disconnect the O
• Make sure that the O
decreases, alarms for low O
3. Make sure that the cylinder are full:
• Open each cylinder valve.
• Make sure that each cylinder has sufficient pressure. If not,
close the applicable cylinder valve and install a full cylinder.
4. Set the system switch to Standby.
5. Test one cylinder at a time for high pressure leaks:
• Turn the flow control knobs fully clockwise to stop gas flow.
• Open the cylinder.
• Record the cylinder pressure.
• Close the cylinder valve.
• Record the cylinder pressure after one minute. If the pressure
decreases more than indicated below, there is a leak.
— 5000 kPa (725 psi) for ventilator drive gas.
— 690 kPa (100 psi) for non ventilator drive gas.
Install a new cylinder gasket and do this step again.
• Repeat step 5 for all cylinders.
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.
6. Connect the pipeline supplies one at a time and ensure that the
corresponding gauge indicates pipeline pressure.
