Good day my fellow colleagues, I really need help to corroborate the amount of refrigerant gas R22 that has a unit that I play revive, it is a window, and it has a compressor of 347,000 BTU, it is a quality unit because it works perfectly, patched and cut capillaries (that is, very short) and had leakage, but it goes perfectly, I just want to know the amount of gas it takes to tell the customer without re-disturbing it, that is, the amount of gas in grms or kgs, not psi, here I leave some photos: IMG-20170911-WA0007.jpeg [340.24kb] IMG-20170911-WA0009.jpeg [222.58kb] IMG-20170911-WA0010.jpeg [259.80kb] IMG-20170911-WA0012.jpeg [274.79kb] IMG-20170911-WA0013.jpeg [281.51kb]
