Important information regulation regarding the refrigerant used
This product contains fluorinated greenhouse gases . Do not vent gases into the atmosphere .
•
Inform user if system contains 5 tCO₂e 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°517/2014 . This activity has to
be covered by qualified personnel only .
•
In case situation above (5 tCO₂e or more of R-410A), installer (or recognized person which has responsibility
for final check) has to provide a maintenance book, with all the information recorded according to
REGULATION (EU) No 517/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 April 2014 on
fluorinated greenhouse gases .
