Start By:a. remove hood1. Remove the air conditioner condenser if so equipped. Prior to removing the condenser, the system must be purged. Refer to the Air Conditioning And Heating Service Manual, Form No. SENR3334-01 for purging the system.
Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publication SENR3334-01, SENR5664 and NEDG5065-01 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-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.
