1. Set the Separator flow to 20 slm at least 2 hr before the fill. In the operational mode, separator flow should be always 20slm so you can skip this step.
2. If the Lquifier that you are going to use is already in the Idle mode, then please switch it to "Liquefy mode". If the liquid level is having large fluctuations which leads to the liquefier to automatically switching to Idle mode, then you can go to the settings and increase the "Dewar High Level" from 84%(~210L) to 86%(~215L) that way we can keep the Liquefier in the "Liquefy mode" throughout this procedure, and remember to set it back to 84% once the fill is done.
3. Then, around 1 hr before the fill, start to cool down the transfer line by opening VJVA/B (ensure VPC is already opened). This is the start time of the transfer.
4. Wait until TX1  reaches ~100 K. While you are waiting, connect to the CCP and get ready to open the Magnet Return Bypass Valve when TX1 is ~100 K.
5. Set Magnet Bypass Pressure PID to 6 psi, and then quickly open and close VJVT (only for a few seconds) while  VPC is open to get the magnet pressure up to 6psi and then close VJVT.
   Note: you may have to open/close VJVT a few times to reach the magnet pressure to 6psi; as you don't want to leave the VJVT open for more than 30 seconds at this stage.
6. Once magnet pressure reaches 6psi, check the inlet flow to the liquefier that you are going to use (~45slm).
   If the Lquifier is already on the Idle mode, then please switch it to "Liquefy mode". If the liquid level is having large fluctuations which leads to the liquefier to automatically switching to Idle mode, then you can go to the settings and increase the "Dewar High Level" from 84%(~210L) to 86%(~215L) that way we can keep the Liquefier in the "Liquefy mode" throughout this procedure, and remember to set it back to 84% once the fill is done, check the inlet flow to the liquefier that you are going to use (~45slm).
   
7. Set Magnet Bypass Flow PID to 55slm and switch to Flow PID (this is for balancing with ~45slm inlet flow to the delivery Dewar).
8. Open VJVT and close VPC. Note: The liquefier that you are going to use is still in "Liquefy mode".
9. At this time, the liquefier will flow exactly the LHe amount that it is producing, to cool the line.
10. Wait for at least 30 mins. You will see the magnet pressure and Dewar pressure are closer to each other.
