NOTICE
Applicable legislation on
fluorinated greenhouse gases
requires that the refrigerant
charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO

equivalent tonnes:
GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
