1. Open the yellow hand valve GV02 (shown in Figure 2: red arrow).
2. Open "VPC" pneumatic valve on the QT-PLC screen.
3. Open "VJVA(or B)" and monitor the temperature on TX1 display on the QT-PLC.
   Example (Figure 1): The Liquid helium will start flowing from Dewar A (via VJVA) and then going towards VPC then going back to the QT recovery manifold (to the yellow hand valve) via the Vaporizer.
