Introduction ESIE05-03vi31451.3.2 Refrigerant CylindersCylinderspecificationsP The cylinder is painted refrigerant color (pink).P The cylinder valve is equipped with a siphon tube.P Note:1 Refrigerant can be charged in liquid state with cylinder in upright position.2 Do not lay cylinder on its side during charging, since it causes refrigerant in gas state to enterthe system.Handling ofcylinders1 Laws and regulationsR410A is liquefied gas, and the High-Pressure Gas Safety Law must be observed in handlingthem. Before using, refer to the High-Pressure Gas Safety Law.The Law stipulates standards and regulations that must be followed to prevent accidents withhigh-pressure gases. Be sure to follow the regulations.2 Handing of vesselsSince R410A is high-pressure gas, it is contained in high-pressure vessels.Although those vessels are durable and strong, careless handling can cause damage that can leadto unexpected accidents. Do not drop vessels, let them fall, apply impact or roll them on the ground.3 StorageAlthough R410A is not flammable, it must be stored in a well-ventilated, cool, and dark place in thesame way as any other high-pressure gases.It should also be noted that high-pressure vessels are equipped with safety devices that releasesgas when the ambient temperature reaches more than a certain level (fusible plug melts) and whenthe pressure exceeds a certain level (spring-type safety valve operates).Siphon tubeCylilinder
