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
for HFC refrigerants.
