CAUTION To prevent damage:
• Open the cylinder valves slowly.
• Do not force the flow controls.
If your system does not use cylinder supplies, do not do steps 2 through 12.
1. Disconnect the pipeline supplies and close all cylinder valves.
If the pipeline and the cylinder pressure gauges are not at zero:
• Connect an O
2
supply.
• Set the system switch to On, if it is not already
set.
• Set the flow controls to mid range.
• Make sure that all gauges but O
2
go to zero.
• Disconnect the O
2
supply.
• Make sure that the O
2
gauge goes to zero. As pressure decreases,
alarms for low O
2
supply pressure should occur.
2. Make sure that the cylinders 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.
3. Test one cylinder at a time for high pressure leaks.
4. Set the system switch to Standby, which stops the O
2
flow.
5. Turn OFF the auxiliary O
2
flowmeter.
6. Turn off the suction.
7. Open the cylinder.
8. Record the cylinder pressure.
9. Close the cylinder valve.
10. Record the cylinder pressure after one minute. If the pressure (for air and
O
2
) decreases more than 5000 kPa (725 psig) there is a leak.
