GasLab Q2
Step
Action: Manual flushing of the high pressure reducer
1.
Ensure that the following requirements are satisfied:
1. Steps 1 to 6 of the gas cylinder connection procedure (see above) have been
completed.
2. Gas can flow into the parts which require flushing. The gas pipeline must be
disconnected immediately upstream of the GasLab Q2 (close gas cylinder) to make
this possible.
Ensure that the flushing gas is discharged in a professional, safe manner.
2.
Slowly open the main valve on the gas cylinder.
3.
Adjust the stream of gas and observe it using the flow indicator. Do not exceed the
maximum pressure levels.
4.
Now close the main valve on the gas cylinder.
5.
If the outlet pressure of the high pressure reducer or cylinder pressure regulator has
fallen to almost 0 MPa, open the gas cylinder briefly and then close it again.
6.
Repeat the procedure described in step 5 several times to ensure that there is no more
air in the dead space of the regulator and the pipeline. Everything will be flushed after
a total of 5 filling and emptying cycles.
7.
After the flushing cycle, immediately continue with step 8 of the “Steps to connect the
gas cylinder” (s
ee above) to prevent contamination.
