Commisioning a new refrigerant refrigerant recovery cylinder

This one covers putting into operation a new recovery cylinder. This video is part of the heating and cooling series of training videos made to accompany my websites: and to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.

  1. 8:02 – "Commissioning a new refrigerant refrigerant recovery cylinder" procedure jump to here. Thank you for the section 608 of the "Clean Air Act" requirements refresher at the beginning.

  2. Hi GFM, any advice on picking up a used / empty / open to the air recovery tank locally? I’ve seen a few advertised for next to nothing, but assume if it’s open to the air, the inside of the tank could be rusty. Best to avoid or will most supply houses swap the used and empty tanks out for a fee?

    Red is always liquid, Blue is always vapor, does not matter what side of the recovery tank, Blue=Low side Red=High side

  4. There’s a date printed on my 134a 30 lbs cylinder. Do you know what the date represents?
    Mine says: 01-08-2021

  5. I have watched many videos made by this man, some over and over, and mimic his style when instructing others learning the trade…It's the common sense approaches that he uses for helping one understand just what he is doing…It's the clarity, the pace, and not talking over someone's heads like many do trying to impress the viewers and/or students with what they, the instructor, already knows…Students don't need to be impressed, they need to be shown how to do it and it explained slowly and clearly, so they can understand it too, while at the same time learning, they can do this…This is the best instructor I have watched and as an instructor, still learn from…Thank you again GrayFurnance man.

  6. good video is it possible to use the recovered r12 from a refrigerator to a older car that uses r12 (1992 etc) ?

  7. We re-use and resell R22 and R410 whenever possible, if it's not a burn out its "clean" and it's just too expensive to waste.
    Shame the video stopped just short of being commissioned with at least a shot of refrigerant

  8. This was very helpful! I purchased a White Industries R1234 machine that was missing the 134a recovery tank. i bought a Mastercool tank and wiring pigtail to install it. Now the 'excessive air' light is on, and i think i know why now…. A question i have is, does the float switch open at 80 %, or close at 80 %? Most diagrams i have seen indicate normally closed, and open @ 80 %.

  9. Do you have any suggestions for me on where to have my recovered r134a recycled? We do not have a recycle machine so we end up with a full "waste" cylinder every summer. Can't seem to find anyone to help me out with this one.

  10. Hey gray hi… hey is that safety need to be closed when you get a new cylinder? i just bought a new one and with 6 pounds of refrigerant in it, it started trowing out the freon by that valve completely,,, i tied the valve all the way down with an allen wrench but it did it again.. it that mean the safety is bad in this thing? thank in advance for response…
