Secure bolometer from turbo pump. 2)Open(CCW) green Nupro Valve on the bolometer. Close(CCW) "Pump" and "He3" switches approximately 30 turns. Retract shafts and secure with vinyl tubing. Tubing is labeled for each shaft. 3)Pre-cool with liquid nitrogen for 1-3 hours, longer is better. Fill LN2 reservoir(outer) first.
