6.7.9 Checks after charging refrigerant
▪ Are all stop valves open?
▪ Is the amount of refrigerant, that has been added, recorded on the refrigerant
charge label?
NOTICE
Make sure to open all stop valves after (pre-) charging the refrigerant.
Operating with the stop valves closed will damage the compressor.

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
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. 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manual might be outdated.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.
