b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Quantity of fluorinated greenhouse gases of the total refrigerant charge
expressed as tonnes CO
f GWP = Global Warming Potential
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
Formula to calculate the quantity in CO
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
