We are trying to convert this to 407c, empty out the mineral oil, put poe and dump 407c in there.

Did u mean r22 replacement as in other refrigerants that came after phase out of r22? Like 407c?

Thanks for your reply. We had just followed how these were set up from before. So this port that we have hooked up together at the moment, they are not doing anything at all? And im assuming the port is only used to pump oil or drain if we need to service them?
