Wow, so its 7:30PM here in Milwaukee on a Friday and I'm leveling out an AC and straightening up the line set in an older system. Pumped the unit down, blah blah blah, and hooked up the vacuum pump. Now with my fieldpiece vacuum pump, it takes me literally 5-10 min to get down below 100 microns but this time it shot down to 400, so i went and finished up the small work, and when i came back it was at 800 microns. Trying every connection to no avail. Decide to watch your video and just when i was about to turn it off as i thought it was no help to me, BOOM!! the service valve on the high side needed to be tightened a smidgen more. 13 years in the HVAC/ELECTRICAL Field and im still learning things the hard way. But it works for me as ill never let it happen again. Now its at 63 microns!! Thanks a lot.

I must admit that due to the e-book being unable to enlarge the fonts/pictures, and reading pages 132-136, this is a lot sayin! Now, your videos are probably the best of any on you tube. Seriously.
