Refrigerant

R-134a refrigerant is a non toxic, nonflammable, clear and odorless liquefied gas.


CAUTION: R-134a refrigerant is not compatible with R-12 refrigerant. Even small amounts of R-12 in a R-134a system will cause lubricant contamination, compressor failure or improper A/C performance. Never add R-12 to a R-134a system.


WARNING: Avoid breathing R-134a refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved service equipment to discharge R-134a systems.
