CAUTION If the needle valve is not fully open, this test can damage
the pressure gauge on the test device.
6. Open the O
2
flow control and set a total flow of 0.4 L/min through
the flowmeter on the test device.
7. Make sure that the pressure gauge on the test device reads zero
and that all other flow controls are fully closed.
8. Close the needle valve on the test device until the test gauge
reads:
9. If the flow through the test device is less than 0.35 L/min,
there is a low-pressure leak in the anesthesia machine.
10. Fully open the needle valve on the test device to decrease the
back pressure.
11. Test each vaporizer for low-pressure leaks:
• Set the vaporizer to 1%.
• Repeat steps 5 through 10.
• Turn the vaporizer Off.
12. Remove test tool.
13. Replace the breathing system.
WARNING Agent mixtures from the low-pressure leak test stay in the
system. Always flush the system with O
2
after the low-
pressure leak test (1 L/min for one minute).
Turn Off all vaporizers at the end of the low-pressure leak
test.
14. Flush the system with O
2
:
• Set the O
2
flow to 1 L/min.
• Continue the O
2
flow for one minute.
• Turn the O
2
flow control fully clockwise (closed).
Without ACGO 1. Turn all flow controls fully clockwise (closed).
2. Remove the breathing system.
3. Connect the test adapter port 1 to the common gas outlet.
4. Connect the test device to the test adapter port 2.
