4. Set the system switch to Standby.
5. Turn off all vaporizers.
6. Test the anesthesia machine for low-pressure leaks:
•Turn the flow controls one and a half turns counterclockwise.
•Connect the test device to the common or auxiliary gas outlet.
•Compress and release the bulb until it is empty.
•The vacuum causes the floats to move. This is usual. If the bulb inflates
in 30 seconds or less, there is a leak in the low-pressure circuit. Refer to
the Troubleshooting table (Part 2 of this manual).
•Disconnect the test device.
7. Test each vaporizer for low-pressure leaks:
•Set the vaporizer to 1%
•Repeat step 6. If there is a low-pressure leak, refer to the Setup,
Maintenance and Troubleshooting Manual.
8. Keep the test device with the system.
