SiBE34-802 Precautions for New Refrigerant (R-410A)Precautions for New Refrigerant (R-410A) 2652 Temperature scale indicates the relationship between pressure and temperature in gassaturated state. Differences2 Change in pressure2 Change in service port diameter7. Charge hose for R-410A Specifications2 Working pressure 5.08 MPa (51.8 kg/cm2)2 Rupture pressure 25.4 MPa (259 kg/cm2)2 Available with and without hand-operate valve that prevents refrigerant from outflow. Differences2 Pressure proof hose2 Change in service port diameter2 Use of nylon coated material for HFC resistance8. Charging cylinder Specifications2 Use weigher for refrigerant charge listed below to charge directly from refrigerant cylinder. Differences2 The cylinder can not be used for mixed refrigerant since mixing ratio is changed duringcharging.When R-410A is charged in liquid state using charging cylinder, foaming phenomenon isgenerated inside charging cylinder.(Hose with ball valve)Can not be used
