To convert a properly functioning automotive R-12 system to FRIGC (FR-12), an installer must:

Recover and recycle the R12;
Evacuate the system ( for approximately 30-45 minutes); using a vacuum pump
Add approx. 2 oz. of Ester (POE) oil
Charge the system to approximately 80 to 90% of the R12 capacity and install the under-hood "system identification retrofit label".
Install retrofit fittings on the high and low side service ports;

It's that simple! In some cases, it may be necessary to adjust the cycling pressure switch on CCOT systems for optimum performance
