1.3.2 Refrigerant Cylinders
Cylinder

P
The cylinder valve is equipped with a siphon tube.

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 enter
the system.
Handling of
cylinders 1 Laws and regulations
R410A is liquefied gas, and the High-Pressure Gas Safety Law must be observed in handling
them. Before using, refer to the High-Pressure Gas Safety Law.
The Law stipulates standards and regulations that must be followed to prevent accidents with
high-pressure gases. Be sure to follow the regulations.
2 Handing of vessels
Since 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 lead
to unexpected accidents. Do not drop vessels, let them fall, apply impact or roll them on the ground.
3 Storage
Although R410A is not flammable, it must be stored in a well-ventilated, cool, and dark place in the
same way as any other high-pressure gases.
It should also be noted that high-pressure vessels are equipped with safety devices that releases
gas when the ambient temperature reaches more than a certain level (fusible plug melts) and when
the pressure exceeds a certain level (spring-type safety valve operates).
