To identify potential gas leaks on the indoor unit, inspect 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 with nitrogen.InsulatorGas sideLiquid sideStep 9 Insulating the refrigerant pipesOnce you have checked that there are no leaks in the system, you can insulate the piping and hose.1To avoid condensation problems, place Acrylonitrile Butadien Rubber separately around each refrigerant pipe.No gapNBRNOTEAlways make the seam of pipes face upwards.2 Wind insulating tape around the pipes and drain hoseavoiding compressing the insulation too much.Insulation cover pipeInsulation pipeIndoor unitBe sure to overlap the insulation.12English
