Warning
The linkage system cannot replace the O2 monitoring device. Fresh gas contains sufficient O2 and
does not necessarily avoid the presence of hypoxic mixtures in the breathing circuit.
Improper gas mixtures can cause harm to animals. If the linkage system cannot provide an
appropriate ratio of O2 and Air, the system should not be used.
The following steps test the linkage system for serious malfunctions, but do not confirm whether the
calibration is correct.
NOTE
The gas flow switch should be rotated slowly. When it exceeds the maximum or minimum flow range
indicated by the flow meter, do not rotate it forcefully to avoid damage to the control valve and control
failure.
To conduct the flow control test, it shall:
1 Connect the pipeline for gas supply
2 Turn all flow controls clockwise and back to all (minimum flow)
3 Turn on the power switch
4 If ventilator fault alarm occurs, the system should not be used
5 Ensure:
There is no gas flow rate display in all the flow tubes
Steps 6 and 7 are used to test the Air system only
Warning
During steps 6 to 7, keep the linkage system in working condition:
Adjust only the test controls (Air in step 6 and O2 in step 7)
Adjust the flow in sequence (Air first and then O2)
If you adjusted the test control too far, set the flow control to its closest position and
perform the step again.
6 Test the flow increase of the linkage system; it shall:
Turn the Air and O2 clockwise flow control, and go to the end (minimum flow).
Turn the Air flow control slowly in the counterclockwise direction.
Set the Air flow control to the flow rate shown in the table.O
2
Flow rate must be greater
than the minimum limit value.
Set the Air flow to (L/min):
O
2
Flow must be more than (L/min):
