Who cares? You should go spew your nonsense over on the External Pressure Vessel forum. We are discussing automotive air conditioning here.Actually, I am ASME External Pressure Vesel Certified, which is something a littlle AC technician can only dream about.
Note: External Pressure is the correct terminology.
Um, no. My pump pulls 29-something inches. The difference between that and 29.92 inches is minor. If the aluminum lines don't collapse at 29-something they probably won't collapse at 29.92. It's a concept known as pressure differential. Once again it's that basic physics thing that you have a shallow grasp on that is failing you.Of course the vacuum achieved by that little AC vacuum pump is not even close to total vacuum, the aluminum lines would quickly colapse if that little AC vacuum pump were more powerful.
If you did not pull a vacuum then you have no idea whether or not you have a large leak.That's exactly my point!
I've never said you should charge a system with a big leak.
You have been asked several times by myself and LPete to divulge your secret superior technique. I will kindly ask you again to fill us in.If you are indeed MACS certified, you can not use this technique. You should know it, but you are not allowed to use it.
This is still not true no matter how many times you repeat it. The main reason to pull a vacuum is to remove moisture and contaminants. It takes more than a few minutes to under vacuum to accomplish that. The Chrysler factory service manual I have says:You are not reading my post, I've said
The main reason to keep vacuum in the system for more than a few minutes is to check for leaks. You don't need to keep a vacuum too long to evacuate the system.
Sure you can. Just close the valves on your gauge set. I can leave my pump running with the valves closed. The pump is no longer connected to the system at that point.You can not check for leaks while the pump is running, so checking for leaks is not a secondary benefit.
OK, you are just making stuff up here and are starting to babble incoherently. You really need to provide some documentation to back up your ridiculous claims.You don't have a glass of water to boil inside the system, just traces of water which doesn't takes long to "boil".
Once you reached the vacuum of 29.92 HG, you only need one minute to evaporate any amount of water in the system.
Again, water vapour obtained after you reach the maximum vacuum achieved by your little vacuum pump will not be removed from the system, it will transform back to water once the vacuum is broke.
In case you don't understand this little fact, once your vacuum pump reach it's maximum, gases will stop flowing out of the system, it will be worthless to keep the pump running trying to keep removing humidity.
So basically you advise people to either listen to the manufacturer or to ignore the manufacturer depending upon how it supports your personal narrative of things.There is not a single one.
I suppose you are not gonna reveal your marvelous technique to the rest of us even though you have constantly bragged about it. I can only conclude that there is no such technique and you are simply making it up just like all the other nonsense that you spew.It is against the law to do it the other way.
You are an expert, you should know it.I suppose you are not gonna reveal your marvelous technique to the rest of us even though you have constantly bragged about it. I can only conclude that there is no such technique and you are simply making it up just like all the other nonsense that you spew.
