LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum
and recirculating the R-410A, it’s responsable of installer to pressurize the
whole system with nitrogen (using a cylinder with pressure reducer) at a
pressure above 2 bar, less than 40 bar (gauge).
LEAK TEST WITH R-410A (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-410A.
Once you have completed all the connections, check for possible leaks using
leak detector specifically designed for HFC refrigerants.
