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
responsability for final check) has to provide a maintenance book, with all the information recorded according to

Make sure that contamination by other refrigerants does not occur for charging.
To minimize the amount of refrigerant, keep the hoses and lines as short as possible.
The cylinders shall be kept upright.
Make sure that the refrigeration system is earthed before charging.
Label the system after charging, if necessary.
Extreme care is required not to overcharge the system.
Before recharging, the pressure shall be checked with nitrogen blowing.
