Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping refrigerant R-134A can cause freezing of human flesh. Do not smoke while working on air conditioning systems. INHALING REFRIGERANT 134A THROUGH ANY SMOKING MATERIAL, ALTHOUGH NOT TOXIC OR FLAMMABLE, CAN GENERATE LETHAL PHOSGENE GAS AND CAUSE VIOLENT ILLNESS OR DEATH. ALSO, HEAT MUST NEVER BE APPLIED TO A CHARGED SYSTEM. See Air Conditioning And Heating Service Manual, Form number SENR5664, for more information on removal and installation of lines and refrigerant from the system. |
