Pressure drop from -30
Hello, Marcelo
good afternoon you seem to get damp and maybe a little leak by flange in connection of nut to robinetes
this does not indicate pressurizing with nitrogen or CO2 or dry air or oxygen etc. a dry gas as it indicates whether or not leakage by connecting nuts to robinetes

Hello Marcelo, Please do not pressure test with oxygen!. Oxygen is the oxidizer par excellence and you can generate an explosion. Do not do it with air. Pressurizing the air increases the partial pressure of O2 and can damage the oil at the molecular level. Especially POE oils. What is indicated for this type of Test is Nitrogen.

Hello, how are you, you know what happens to your equio, you performed a bad procedure that was to start the computer without have opened the robinetes before to release the refrigerant inside the circuit, the flaper is doubled because it does not have place to leave the pressure, the correct procedure after the vacuum is to open the two robinetes wait a couple of minutes and then put the equipment in operation, I hope I'm wrong, but I do not think that compressor compliments greetings.
Hi Beltran, you are indicating to pressurize with oxygen which is extremely dangerous since in contact with the oil it is explosive. regards
Sorry for the Beltran reiteration, but please do not pressure it with oxygen. Oxygen is the oxidizer par excellence and you can generate an explosion in the case of mineral oils. Neither do you do it with air. Pressurizing the air increases the partial pressure of O2 and can damage the oil at the molecular level. Especially POE oils. What is indicated for this type of test is Nitrogen.
Does all the tests possible, controls the consumption if it is low is not a good signal, if it does not change, recover the refrigerant and test the compression of the compressor in this way you are going to realize, but for your peace of mind everything I said my criterion is the problem, anyway read comments and tests and do not close the question until you have reached the solution of the problem
Well estimated. Many thanks x the advice. Then d review what he had done, I described above, I have dafo account qm has gained anxiety. The problem is that I did not let the MC work in the cold enough x to have the adequate performance x to receive the gas that was missing. I recharged it and it was fine. Thank you so much
