charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
2 Fix the label on the inside of the outdoor unit near the gas and liquid stop
valves.
