Just wondering what if any good, or bad might result from pulling a vacuum on a glycol/water loop and letting vacuum pull glycol and water into loop? Thought process was to eliminate as much air from loop as possible at fill as options for eliminating air after fill are not best case senario, but possible. We gave it a shot today and it seemed to go well, no air at multiple petes' plugs in mutiple locations, not able to run pumps yet, as always waiting on electricians. Any comments welcome, I live to learn and won't be discouraged if I appear stupid, just have not had to fill too many loops and was wondering if this proccess might work. Situation includes liebert drycooler on thirteenth floor, watercooled condensors on eighth floor connected to airhandlers on same floor.
