7.
Test the O
2
flow control:
•Set the N
2
O flow to 9.0 L/min.
•Set the O
2
flow to 3 L/min or higher.
•Slowly turn the O
2
flow control clockwise.
•Make sure that the N
2
O flow decreases.
The measured O
2
concentration must be
≥
21% through the full range.
8.
Set the flow controls to mid range and make sure that the flowtube floats
move smoothly.
9.
Stop the O
2
supply. Disconnect the pipeline supply or close the cylinder
valve.
10. Make sure that:
•The low O
2
supply alarm occurs.
•N
2
O, CO
2
, Heliox, and O
2
flows stop. The O
2
flow stops last.
•Air flow continues.
•Gas supply alarms occur on the ventilator if the ventilator uses O
2
as the
drive gas.
11. Turn all of the flow controls fully clockwise (minimum flow).
12. Reconnect the pipeline supplies.

To prevent damage, turn the flow controls fully clockwise
(minimum flow or Off) before you turn On the system.
1.
Turn the system On. Alarms can occur.
2.
Set the O
2
flow to 6 L/min.
3.
Make sure that the O
2
flow stays constant and the float moves freely.
4.
Adjust the vaporizer concentration from 0 to 1% one click at a time. The
O
2
flow must not decrease more than 1 L/min through the full range.
If the O
2
flow decreases more than 1 L/min:
•Install a different vaporizer and try this step again.
•If the O
2
flow decreases less than 1 L/min with a different vaporizer, the
malfunction is in the first vaporizer.
