1445 Everything looks good. Place tower in purge cabinet overnight.
1545 Begin opening Soudan IT4 shipping vessel in clean room
Pressure = 14.2 PSI. (Somewhat higher than tape mark, which makes sense since it was pressurized in the mine which has a higher atmospheric pressure.)
Remove small cap at end of pump port. Open valve, just enough to let pressure out slowly.
1600 Remove top of shipping vessel using 5/32 hex key
Cover disk at 4K stage is labeled ZB-8. I don't think this is the tower ID; the cold hardware elog has tower IDs that all start with ZB1-something.
update: I think this tower is ZB1-7.
1615 Remove screws attaching tower ears to vessel base using M4 hex key. Lift tower out of vessel.
1622 Place tower in large purge cabinet
