Massive Water Chiller

I don't know how R507A acts but I do know that it is composed of 50% R125 and 50% R143A that would lead me to believe that when you charge as vapor you may change that 50/50 mix I would just not do it, but anyway you are using R404A which is a ternary blended refrigerant so you definitely must charge as a liquid.

Just charge slowly as liquid keeping your hand on the valve feeding it a few seconds at a time I have no idea how small amounts of liquid would affect a rotary compressor, but I doubt it would be a big deal if you did get a tiny amount through on initial charge.

No, I chose R507. Though, I can see how you that was misleading. I was just differentiating between 404a and 507... although they aren't all that different in terms of make-up.... 507 is an Azeotropic blend and 404a is not quite..... But its all irrelevant now, since I'm going to liquid charge it anyways. (Not exactly two different animals as I said... I know... I exaggerated. )
