  1. Check the outside gHe pressure and make sure it is below 90 psi. If it's equal, near or above, then relief it's pressure down to ~80 psi.
  2. Set the liquefier to "Manual" mode.
  3. Navigate to the liquefier page on the HMI screen.
  4. Open SVP(A/B)
  5. Navigate back to the "Overview Screen".
  6. Start pre-cool phase:  Open VPC → Open VJV(A/B) → Monitor TX1, TX2, TX3
  7. After ~8mins: Open magnet-bypass (hand-valve right next to the magnet flow controller) → Open VJVT on the HMI screen.
  8. After ~1min: Close VPC and monitor magnet pressure and maintain ~5psi on the QT dewar using REGX (green) hand valve.Try to regulate the pressure difference of ~4psi .
    ** Note: If the REGX green hand valve is fixed, then do not change it: jut proceed with step #9 *****
    ***************************************************************************************************
    > If you need to change the pressure difference between the magnet and the Dewar , using then use the REGX all the time .to maintain the pressure difference that you need (eg: ~4psi)
  9. After a couple of minutes, you will observe that the magnet pressure drops down suddenly and stay around ~1.4-1.5 psi (this indicates that LHe is flowing to the magnet after the pre-cooling of the last part of the transfer line).
  10. Fill the magnet until the level shows ~44% → Open VPC → Close VJVT → Close VJV(A/B) → Close Magnet bypass hand valve. Make sure that you leave the VPC open to capture all the boil-off from the transfer line until it is warm (check TX1).
  11. Navigate to the liquefier page on the HMI screen and close SVP(A/B) → Switch the Liquefier to "Liquefy mode".
