WARNING The Link system cannot replace an O
2
monitor. Sufficient O
2
in the
fresh gas may not prevent hypoxic mixtures in the breathing
circuit.
• Nitrous oxide (N
2
O), if available, flows through the system
during this test. Use a safe and approved procedure to collect
and remove it.
• Incorrect gas mixtures can cause patient injury. If the Link
system does not supply O
2
and N
2
O in the correct proportions,
do not use the system.
Important Test the O
2
monitor as described in Alarm tests, step 8, before continuing.
To do the flow control tests:
1. Connect the pipeline supplies or slowly open the cylinder valves.
2. Turn all flow controls fully clockwise (minimum flow).
3. Set the system switch to On.
4. Do not use the system if low battery or other
ventilator failure alarms occur.
5. Make sure the O
2
flowtube shows approximately
.025 to .075 L/min. (0.200 L/min. for single-tube variants). The other
flowtubes must show no gas flow.
• Steps 6 and 7 are only for systems with
N
2
O.

WARNING
Keep the Link system engaged during steps 6 and 7:
• Adjust only the test control (N
2
O in step 6 and O
2
in
step 7).
• Test the flows in sequence (N
2
O then O
2
).
• The O
2
sensor used in steps 6 and 7 must be correctly
calibrated.
6. Test the Link 25 system with flow increasing:
• Turn the N
2
O and O
2
flow controls fully clockwise (minimum flow).
• Slowly turn the N
2
O flow control counterclockwise.
• Make sure that the O
2
flow increases. The measured O
2
concentration must be ≥ 21% through the full range.
