Pressure Vessels, Handling
Seal the cylinder and store in a well ventilated cool area.
The refrigerant is heavier than air, gas leaks spread especially on the ground.
Protect from heat and direct sunlight, do not store in areas with temperatures above 50 °C (122 °F).
Do not store near basements or other low laying areas.
Only store in well ventilated areas.
Keep the cylinder away from ignition sources!
Do not smoke in areas where there is Refrigerant R1234yf. In addition take measures against electrostatic charge.
Secure cylinders to prevent them from falling over.
Secure upright cylinders to stop them falling over and secure cylinders lying flat to stop them rolling away.
Do not throw the cylinders.
If dropped, the cylinders could be so severely deformed that they rupture. The refrigerant evaporates immediately, releasing considerable force. Flying fragments of cylinders can cause severe injuries.
To protect the valves, cylinders must only be transported with the cap screwed on.
Valves may break off if cylinders are not properly transported.
Never store in the vicinity of radiators.
High temperatures may occur next to radiators. High temperatures are also accompanied by high pressures and the maximum permissible cylinder pressure may be exceeded.
No Warming above 50 °C (122 °F)
To avoid possible risk, pressure vessel regulations specify that cylinders with refrigerant are not to be heated above 50 °C (122 °F).
No Unmonitored Warming
Do not heat using an open flame under any circumstances. Localized overheating can cause structural changes in the container material, which then reduces its ability to withstand pressure. There is also a danger of refrigerant decomposition due to localized overheating.
Empty Cylinders, Sealing
Empty refrigerant cylinders must always be sealed to prevent moisture from entering. Moisture causes steel cylinders to corrode. This weakens the cylinder walls. In addition to this, rust particles from cylinders that enter the refrigerant circuit will cause malfunctions there.
