I went to clean this equipment and they tell me that it does not cool, it is a 15000 fr equipment. that works with a fancoil as an evaporator unit. When I speak the Evaporator, I see the serpentine totally frozen. The condenser with the drain pipe completely frozen, with refrigerant pressure R22 at 10 pci. I try to load gas and I can't overcome that pressure, as it doesn't let me. What I did was close the discharge line so I can load faster, but it is impossible. There will be a problem or is there a technique for loading. Thank you.

solved Thanks a lot.-
