Note US legislation relating to Air Conditioning (A/C) refrigerants, J2845 Technician Training for Safe Service and Containment of Refrigerants Used in Mobile Air Conditioning (A/C) Systems (HFO-1234yf). It states that under no circumstances should any part of the A/C system be serviced, dismantled, or replaced by anyone other than suitably qualified and certified personnel. Make sure that the refrigerant is correctly contained at all times. Failure to adhere to the above may result in serious personal injury or death.


All replacement parts for the A/C system must be new and equivalent to the manufacturer's original equipment. All replacement parts must comply with the relevant local standard. Contact a retailer/authorized repairer for advice. Failure to comply with the standards could lead to serious injury or death.

The A/C system contains HFO-1234yf (R-1234yf), which is a low Global Warming Potential (GWP) tetrafluoropropene refrigerant. The A/C system is sealed and has a leakage rate of less than 3% per year.
