Important information regulation regarding the
refrigerant used
This product contains fluorinated greenhouse gases. Do
not vent gases into the atmosphere.
CAUTION
• Inform user if system contains 5 tCO
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 tCO
R-32), 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.
Please fill in the following with indelible ink on the
refrigerant charge label supplied with this product and
on this manual.
• : The factory refrigerant charge of the product.
• : The additional refrigerant amount charged in the field.
• + : The total refrigerant charge.

LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before
recreating the vacuum and recirculating the R-32, it is
the responsibility of the installer to pressurize the whole
system with nitrogen (using a cylinder with pressure
reducer) at a pressure above 4 MPa (gauge).
LEAK TEST WITH R-32 (after opening valves)
Before opening valves, discharge all the nitrogen into
the system and create vacuum. After opening valves
check leaks using a leak detector for refrigerant R-32.
Once you have completed all the connections, check for
possible leaks using leak detector specifically designed
for HFC refrigerants.
