Note: The air conditioner may only be installed by a company certified under Regulation (EU) No. 517/2014 of the European Parliament and of the Council of April 16, 2014, on fluorinated greenhouse gases. By purchasing a split air conditioner, you confirm that it has been professionally installed by certified specialists. Refrigerant leaks contribute to climate change. Refrigerants with lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with higher global warming potential (GWP). A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming than 1 kg of CO2 over a 100-year period, proportional to the refrigerant's GWP value. Do not perform any work on the refrigerant circuit or disassemble the unit – always consult qualified personnel.
