Regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publications SENR3334-01 and NEDG5065-01 for the proper, equipment and tools to reclaim refrigerant from any Caterpillar machine. Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping Refrigerant-134A (Dichlorodifluoromethane ) 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 No. SENR3334-01, for more information on removal and installation of lines and refrigerant from the system. |
