OK guys, doing this today. I think I have everything I need (or can rent it) I have one last question.

I found instructions on re-calibrating the POA valve on a Nova site along with a video, and I found the proper setting on this site (20PSI for 134a 30 for R12). Wondering, do I flush the POA valve? there doesnt seem to be a good way to do it, I can certainly rinse it I guess but the only way I can see to flush it is to send flush through it in the same manner I send air through it to recalibrate it.

EDIT.... found answers on other sites, and this one. NO way to flush it its more of a soak, shake, drain process.
