Re: Setting up a dx milk tank?
You can retrofit to R-438A without changing anything.
One thing that bother me though. If the tank was standing with open refrigerant pipes for a long time, oil that is still in the evaporator became acidic and might have caused holes. I advise you to to vacuum each circuit and pressure test with OFN up to 8 bar to make sure circuits are leak free.
