Before the vehicle is started, the static system pressure should be read. Pressure values should be very nearly equal on both LP and HP gauges. The actual static pressure will depend on the ambient temperature. To ensure it is on the right level, refer to a static pressures table applicable for R134A refrigerant (N.B. not shown on this poster). HFO-1234yf is a new class of refrigerants known as hydrofluoroolefins. These refrigerants are similar to HFC refrigerants except that they have a much much lower Global Warming Potential number.
