6. Monitor the dewar temperature as it drops to 7 K [TIDA/B]. Once it get to around 10K reduce the outlet flow. Once the level starts to fluctuate between 0.2 and 1.9L liquid is starting to accumulate [I need to take pictures of the strip charts, showing 7K and the liquefier level starting to fluctuate.]
7. Then, The final step is to set the outlet flow at 2slm to let it start to liquefy over the next several hours. Every few hours you should check on it and see that the production rate is making sense (should be close to 4L/h).
