Precautions for New Refrigerant (R-410A) 269
1.2 Refrigerant Cylinders
Cylinder specifications
The cylinder is painted refrigerant color (pink).
The cylinder valve is equipped with a siphon tube.
Handling of cylinders
(1) Laws and regulations
R-410A is liquefied gas, and the High-Pressure Gas Safety Law must be observed in
handling them. Before using, refer to the High-Press
ure Gas Safety Law.
The Law stipulates standards and regulations that must be followed to prevent accidents
with high-pressure gases. Be s
ure to follow the regulations.
(2) Handing of vessels
Since R-410A 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 une
x
pected accidents. Do not drop vessels, let them fall, apply impact or roll
them on the ground.
(3) Storage
Although R-410A is not flammable, it must be stored in a well-ventilated, cool, and dark
place in the same
way as any other high-pres
sure gases.
It should also be noted that high-pressure vessels are equipped with safety devices that
releas
es 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).
Refrigerant can be charged in liquid state with cylinder in
upright position.
Caution: Do not lay cylinder on its side during charging, since
it cause refrigerant in gas state to enter the system.
