1. Set up the gas scavenging system.
• Attach a patient circuit and plug the patient port.
• Attach a bag to the bag port (or plug the bag port).
• Adjust the APL valve to minimum.
2. Connect the pipeline supplies or slowly open the cylinder valves.
3. Turn all flow controls fully clockwise (zero flow).
4. If equipped, set the ACGO selector switch to Breathing System.
5. Set the system switch to On and set the Bag/Vent switch to Bag.
6. Adjust O flow to 0.5 L/min.
