19EnglishInstallation ProcedureLEAK TEST WITH NITROGEN (before opening valves)Pressure check the refrigerant system using highpressure nitrogen in order to detect basic refrigerantleaks Before performing the vacuum process andreleasing the factory R-410A charge into the refrigerantpipes, it is the responsibility of the installer to pressurizethe whole system with nitrogen (using a cylinder withpressure reducer) at a pressure above 4 MPa (gauge).LEAK TEST WITH R-410A (after opening valves)Before opening valves, discharge all the nitrogen into thesystem and create vacuum. After opening valves checkleaks using a leak detector for refrigerant R-410A.Once you have completed all the connections, check forpossible leaks using leak detector specifically designedfor HFC refrigerants.Step 10 Adding refrigerant (R-410A)Important information regulation regarding therefrigerant usedThis product contains fluorinated greenhouse gases.
