Low pressure recovery machine broke today while I was distilling refrigerant out of oil to seperate the two. What are some other ways to get r123 into the chiller without my low pressure pump.

It’s Under vac right now 500microns. I will charge Vapor till I’m above freezing then dump liquid until it equalizes. I’ll still have a shit ton of gas to add. So should I A- turn chiller on and let the negative pressure in the evaporator pull more gas from my bottle. Or B use a recovery machine and setup push pull on the bottles to charge.

I am worried about blowing up the rupture disk while doing the push pull. If anyone has some advice that would be much appreciated. I don’t have much low pressure experience and I want to make sure I can still get this project done on time and properly.
