Important information regulation regarding the refrigerant used
• Inform user if system contains 3 kg or more of fluorinated greenhouse gases . In this case, it has to be checked
for leakage at least once every 12 months, according to regulation n°842/2006 . This activity has to be covered by
CAUTION
qualified personnel only . In case situation above (3 kg or more of R-32), installer (or recognised person which has
