AC refrigerant recovery machine - Robinair RG3 setup and testing

Hey there, so I have a few projects Id like to work on in my shop, unfortunately it is hot an uncomfortable out there.  I used to have a couple of window AC units on the roof of the shop with a hole cut in the roof to vent the cool air to the shop but that setup would sometimes leak, and would have to be re-waterproofed every couple years.  I eventually just had to replace the roof last fall and don't want to cut a hole in the roof again.

So, I figured I would modify the window AC units I already have and convert them into split units where the evaporator is in the shop, and condenser is on the roof of the shop with just a couple small copper lines, and wires between the two.  To do that I need to recover the refrigerant that is still in the system before I can cut the lines and take it apart.  So I picked up this refrigerant recovery machine (refrigerants are an environmental hazard and shouldn't be released to the air) also just a note to use this legally in the US you should have your EPA certification to work on air conditioners.  Now on the the project, I tried this out and was able to pull out all of the refrigerant into a recovery tank and will be able to re-use it when the AC is put back together as a split unit.
