Sorry, forgot to respond over the weekend when I saw the post. Xringer said it perfectly. I chose to disconnect my vacuum pump and micron gauge prior to releasing the charge. The issue with this...

No problem, it sounds like you're on the right path. My experience with freight companies and damage has been zero. Once tied down to a pallet, rarely anything bad happens, so I would tend to...

Quick note on that insulation. The one's I had previously seen branded under the name Frost King in big box stores are junk (and probably not even appropriate for refrigeration applications). But I...
