FYI, a system with a 10% charge will have correct pressures at rest. but once activated it will run down the low side fast and kick off. since the refrigerant carries the oil to the compressor a low charge will destroy the comp., fill the condensor with debris, coat the inside of lines and evaporator with "black death" reducing system efficiency, and plug the orifice tube screen.

make sure the system is full with the correct charge by weight, NOT PRESSURE
