Air Conditioning System

Spec	Value
Air Conditioning	The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. If equipped with R134a (Global Warming Potential = 1430), the system contains 1.000 kg (2.205 lb.) of refrigerant, which has a CO2 equivalent of 1.430 metric tonnes (1.576 tons). If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 0.810 kg (1.786 lb.) of refrigerant, which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons).
