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. That GWP is based on
the current legislation on fluorinated greenhouse gases. The GWP mentioned in the
manual might be outdated.
2 Fix the label on the inside of the outdoor unit near the gas and liquid stop
valves.
Before connecting the water piping
