why not run the compressor and still weigh in the charge??????? Do that on
almost every system I charge...

you need to run it probably more than once a year, when you run it, it
circulates the oil, and therefore, re-oils all of your o rings and seals,
which are the number one leak points.....
If you have sediment you have problems......bigger than you might think......
