*USE CONDITIONS:
1. Many refrigerants, including R401A (made by DuPont), R401B (DuPont), R409A (Elf Atochem), Care 30 (Calor Gas), Adak-29/Adak-12 (TACIP Int’l), MT-31 (Millennia Tech), and ES-12R
(Intervest), have not been submitted for review in motor vehicle air conditioning, and it is therefore illegal to use these refrigerants in such systems as an alternative to CFC-12.
2. Acceptable Subject to Use Conditions regarding fittings, labeling, no drop-in, and compressor shutoff switches.
Unacceptable; illegal for use as a CFC-12 substitute in motor vehicle air conditioners
3. Although some blends contain flammable components, all blends that are Acceptable Subject to Use Conditions are nonflammable as blended.
4. Freezone contains 2% of a lubricant
5. HCFC-22 content results in an additional use condition: must be used with barrier hoses
