(Does that make sense?)

John,
Yes it does make sense, and thank you. Now, is there a certain point
at which the second pump should be opened? Do you do this at the final
bombing temp, or do you allow the unit to cool some, then open it? Which
would be more efficient and provide a better evacuation?
BTW How's the move going?
Best Wishes,
