R12 to R134a Charge Conversion Formula (pounds only) A charge level between 75% and 85% is recommended when converting from R12 to R134a refrigerant If no conversion information is provided, there is an easy formula to calculate the difference in charge level
- What Happens If You Put R134a in an R12 System? - techtown
To be able to use R134a in an R12 system, the R12 system needs to undergo a retrofitting so that it’s able to handle and process R134a refrigerant This also means that some refrigerant conversion needs to be done in order to drop R134a into a R12 system On top of the retrofitting, the R12 system needs to be properly cleared of the refrigerant
