the connection area of each refrigerant pipe using a leak
detector for R-410A.
Before recreating the vacuum and recirculating the
refrigerant gas, pressurize the whole system with
nitrogen (using a cylinder with a pressure reducer) at a
pressure above 4 MPa in order to immediately detect
leaks on the refrigerant fittings.
Made vacuum for 15 minutes and pressurizing system
