When you apply vacum on the ac system, do you do that from the high side?
Ab, if you are using a vacuum pump...it is best to hook up both high and low side hoses..using conventional ac gauges. If you only have one gauge or hose..it doesn't matter, as the vacuum pump will pull thru the comlete system. To be sure if using only one hose and 1 gauge...pull from the low side and when you are at 28" vac. Connect on the high side to check vac, level.
Thanks for the information!
