Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publication SENR5664 and NEDG5065 for the proper procedure, 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 R-134A can cause freezing of human flesh.Do not smoke while working on air conditioning systems. INHALING REFRIGERANT R-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. SENR5664, for more information on removal and installation of lines and refrigerant from the system.
1. Using the proper procedure recover the refrigerant from the system. 2. Disconnect tube assembly (1) and hose assembly (4) from accumulator (2).3. Remove two bolts, and washers (3) and remove the air conditioning accumulator (2). For installation of the air conditioning dryer, reverse the removal steps. Check all O-rings for damage and replace where necessary. Some models may be equipped with quick disconnect couplings. If this is the case, it will not be necessary to evacuate and recover the refrigerant. If the machine is not equipped with quick disconnect couplings, plug and cap the air conditioning lines leading to and from the accumulator. This will prevent moisture from entering the system. For charging the air conditioning system refer to Form No. SENR5664.End By:a. install hood
