| | Status: Tower partially installed. Mixture has been cleaned a few times, probably enough but maybe will clean once more. |
| 0855 | Check Trap 2 at G1. Pressure actually goes down 5→2.3 mbar so must have been empty already. Pump out a bit with scroll pump |
| 1130 | Tower installed, striplines plugged in. Initial quick electrical check looks OK. Will check again after putting on bottom IVC. |
| 1200 | While putting on bottom IVC, do electrical check at BOB. All looks fine. |
| 1210 | IVC bottom screws mostly tightened. Start pumping gently on IVC with scroll pump. |
| 1225 | IVC = 0.30 bar (measured on mechanical gauge above green valve) |
| 1230 | Scroll pump = 0.19 mbar, pumping on IVC. Pumping valve now completely open. |
| 1230 | Scroll pump = 86 μbar, pumping on IVC. Switch to pumping with turbo. |
| 1440 | Turbo pump = 0.34 μbar, pumping on IVC. With valve closed IVC = 30 μbar. |
| 1520 | Turbo pump = 0.25 μbar, pumping on IVC. With valve closed IVC = 40 μbar. (Waited a lot longer after closing valve than last time.) |
| 1525 | Begin pumping IVC with Leak Detector. LD = 20 pbarL/s and falling. |
| 1530 | LD = 8.1 pbarL/s and flattening. |
| 1540 | LD = 7.4 pbarL/s and flat-ish. Start squirt-tests of IVC from top of fridge down. |
| 1545 | Squirt all IVC vacuum joints, no leak seen. Leak signal stays between 7.2-7.5 pbarL/s. |
| 1545 | Start pumping IVC with turbo again |
| 1615 | Finish raising main bath. |
| 1630 | Check for any gas in fridge. Pump out G1 and P1 volumes with scroll pump, then isolate them, then open Condenser to G1 and Still to P1. Each goes up from about 1.8 to about 2.3 mbar. Pump out with scroll pump. |
| 1650 | P1 down to 0.4 mbar. Stop pumping out fridge. |
