Slow Pre-cooling:
1. Enable the Flow PID control of the Magnet Return Bypass at 65 slm.
2. Open VJVA/B, open VJVT and close VPC.
Note: Liquifier A/B should be on Liquify mode. If at the time of starting the slow pre-cooling the Liquifier A/B is on Idle mode, start the slow pre-cooling and when 4L are consumed on the Liquifier then change it to Liquify mode.

1. Open VJVA/B (ensure VPC is already opened).
2. Wait for TX1 temperature to drop bellow below 100K (~ 4 min with GV02 fully opened).
3. Enable the Flow PID control of the Magnet Return Bypass at 65 slm.
4. Open VJVT and wait for magnet pressure to increase to 6 PSI.
5. Close VPC and proceed to the filling steps.

Proceed to the filling steps anytime after the transfer lines are cold. The system is sufficiently cold once the Tank T temperature decreases after opening VJVT (about 1 hour).
