Re: Converting factory AC to use R134a
FWIW, POA update,is a POS in my oppinion. Stay with the genuine POA AND ADJUSTMTO 26 psi. Test rig is easy to fabricate. I tested my original POA and is fine. Calibrated to 29.5 psi for R-12. Next chance imget, the POA update is coming out in favor of the POA.
