When I intall equip the mfg requires your vacuum to reach 250 to 500 microns and hold for a set amout of hours (depending on the mfg.)
Are you just making fun of me, or are you really clueless?
WTF are you talking about ? I think that you may be lost somewhere . First you 1/2 quoted a statement that I made but are arguing about a statement that someone else made !! Oh and do me a favor , please do not quote what I say out of context !! This is what I said .... when your gauge on your manifold gets to 30"hg your actual micron level can be 5,000+ !!!
