Hello,
I am looking for High Pressure Air Conditioning service port. I have read that the 850s don't have them, but others have said that they do. If they do can someone direct me as to where it is? Pictures would be great, thanks!

 

Its right on the high pressure line, it has the preostat (pressure switsh) connected to it.

 

ill have to look for it, i know very little. if you can get a picture it would be great

 

But you dont need the high pressure port..

 

thanks, and you don't? i can get mine charged at the shop for free so i figured they would need both

 

To vac and charge all you need is the low pressure port.

 

okay great. Thanks!
