Highlights of R-1234yf Meets SAE J2888_201301 ""This SAE Standard covers fittings, couplers, and hoses intended for connecting service hoses from mobile air- conditioning Systems to service equipment such as charging, recovery and recycling equipment"" New tools and equipment are required. To service vehicles equipped with R-1234yf refer to SI B04 02 16. Air conditioning technician certification is required to work on system. Refer to your State Law. Unique low and high side fittings. Revised evaporator core as per SAE J2842. System will use about 5% more refrigerant than a comparable R134a system. System oil is a specific PAG oil. Refer to ISTA repair recommendation. Do not interchange components between systems using other refrigerants. Do not reuse Seals / O-ring material from another system. The system piping has internal heat exchangers (IHX or IWT) as introduced in the G12 (7 series). SAFETY INFORMATION Several precautions need to be observed when working on automotive air conditioning systems: Always wear eye protection and gloves while handling refrigerant or servicing air conditioning system. Avoid breathing R1234yf lubricant vapor or mist. Use only approved service equipment to discharge A/C systems. If refrigerant or compressor oil contacts the skin or eyes, large quantities of cool water should be used to flush the affected area. Never heat a refrigerant container with an open flame. Keep all refrigerant away from open flames. Under no circumstances should R1234yf service equipment or vehicle A/C systems be pressure tested or leak tested with air/R1234yf mixtures. NOTE: The use of compressed air (shop air) for leak detection in an R1234yf system can contaminate the system and/or refrigerant with moisture. Leak detection equipment that meets the SAE J2791 standard will work with R1234yf Never use fittings for an R12 or R134a system on an R1234yf system. Any difficulty in connecting service equipm
