I was going thru the sanden compressor plant in Ft Worth one year and they put on this demo. Took a old coke bottle, put one inch of water in it and hooked up gauges. When they hit 28" vacuum the water started boiling at room temperature. Cant remember how long it took to get all the water out but is seemed to be about 15 minutes best I can recall. THat was in 1988 or so when I worked for the Yugo car co.
How long do you leave the vacuum pump on the a.c. unit?
