Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping refrigerant R-12 (C C12 F2 Dichloro Difluoro Methane) and refrigerant R-134A can cause freezing of human flesh. Do not smoke while working on air conditioning. Inhaling Refrigerant R-12 or R-134A through any smoking material, although not toxic or flammable, can cause violent illness. Also heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual Form No. SENR3334-01 and SENR5664, for more information on removal and installation of lines and refrigerant from the system. |
