comes out Thank you very much if you still have 1 and a half pounds of pressure when I measured it but I didn't know if I could load gas since the system is still closed, what if I don't know if I connect the hose and when it starts before tightening the valve, open the gas and a little refrigerant leaking so that there is no air left in the hose and the hose has just been adjusted properly; or connect the direct hose and start charging the freon normally that you would recommend me thanks
I use a bone manifold are two watches to measure HIGH AND LOW pressure and each watch has a hose connection below I connect the hose with a low clock and with the low key closed, I connect hose to a compressor valve and then I open a little to purge hose low. Just there, I connected the hose of the gas cylinder to the manifold and purged that hose by opening the other high key and closing the key. Just there I have the two hoses filled with gas just there I can open the low key so that gas enters
