Long manipulator checkout - ok
NF3 leak valve: evacuated reservoir behind leak valve into turbo cart, closed leak valve for bake (not tight)

RGA turned on, warmed up and preliminary leak test of prep chamber good.

Isolated turbo cart from system for leak test, and since the pressures are similar, valved out the cart and turned it off for the weekend. The bake pump and prep chamber pump are pumping on the system, and when the pressure is better Monday, I'll repeat the leak test.

The 480v ac power has been installed internally of the supply. Known items that still need to be installed are the voltage verification unit, ground the transformer and the scr, install the new breaker handle on the new breaker in the power supply, verify that all the labels are correct. Vacuum any debri inside the power supply. If I have missed anything please let me know. Work will continue on Monday..
