So the system is holding 25 inches of vacuum for two days. I want to make sure I charge it correctly. How do I determine how much oil is in the system and if I need to add any? I have POE oil encase I need to add some. I read that hotshot 2 should be charged as a liquid and initially into the high side on a dry system, compressor off. (I added a high side port.) is this correct? What high side/low side pressures should I shoot for?
Thank you in advance.
