NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO
2
-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit. There is a
dedicated place for it on the wiring diagram label.

5.7.2 Guidelines when knocking out knockout
holes
NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing.
▪ After making the knockout holes, we recommend you
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
