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.

Thank you, I really appreciate this video. I haven't found very many videos on RUclips showing the proper step-by-step method for recovering refrigerant from small units like this, refrigerators and freezers. This was informational, accurate, has good lighting, clear audio and no music. Thank you! subbed.

Thanks, I am glad you liked it!

Good work. Thanks

Does it come with the tank

[@planbuildplay8528]

No, the tank is sold separately

[@adaml3042]

Does this machine handle R-134a?

[@planbuildplay8528]

Yes it will work with R-134a. If working with more than one refrigerant just use separate recovery tank to avoid mixing refrigerants. There is a link to the model I used in the video description.

[@demomack1188]

It dont come with dryer either

[@planbuildplay8528]

Is the dryer no longer included with the machine? It looks like they do have replacement ones available too, I added the link to that in the video description.

Does this recovery machine have a PURGE on it to clear the refrigerant from it?

[@planbuildplay8528]

There is not a purge setting, but after done recovering from the air conditioner you can close the low side valve and run the machine to clear any refrigerant out of the machine.
