  WARNING: Air conditioning refrigerant R-134a and R-1234yf gases are capable of displacing the air necessary for breathing in a confined space and can produce toxic gasses if burned at high temperatures. Do not release a large quantity of R-134a or R-1234yf gas within a confined space or allow it to be exposed to a high temperature flame (such as a torch). Consult the Material Safety Data Sheet (MSDS) for further information. Failure to follow these instructions may result in serious personal injury or death.
