Continue the process until the system has been determined to be leak-free. Connect the vapor-line and liquid-line pressure taps to a vacuum pump and micron meter. This step is also almost always omitted. Evacuate the refrigerant lines and indoor coil to at least 350 microns. Close off the valve to the vacuum pump and observe the micron meter.Make sure there is as much liquid in the evaporator as possible, but ensure it is completely boiled off before it enters the compressor. This can be seen by measuring the superheat. To measure evaporator superheat: Record the actual temperature at the TXV bulb with a probe. Record the evaporating pressure at the TXV bulb.
