Accidentally put a 1/2 -3/4 lb of r22 into a flat (due to leak ) r410 system. Ran gas and vapor through the compressor then realized I made the mistake. Immediately purged out presssure to flat again. Came back 4 days later did nitrogen leak check,evacuated to 250 microns recharged system with 410. System seemed to run fine. Do you think I'm OK here?
