I've seen some of that stuff before and of course watched the RedNeck hack again. (3rd time I think).

The main goal of removing all the R410A from the system would be to allow the system to be cleaned out, with a flushing agent.
This would allow for replacing the POE oil (which might be contaminated) when recharging the unit.

I'm running tests on this repaired system, and I'm still a bit worried the compressor might be in danger of being damaged,
due to bad (or a lack of) POE oil..

I did like those DIY systems that incorporated oil separators.
Since you would not want old oil in your storage tank.

If I decide to buy a new indoor unit for this repaired system,
It might be best to have a very cleaned up 'charge' in the system,
before installing the new indoor unit.
