6.4 Replacing the carbon dioxide cylinder (CO
2
)
When the needle of the reducer high pressure gauge is in the red segment, the cylinder needs
replacing.
1 -
Note down the pressure values set on the pressure reducer, then fully close the cylinder
using its valve.
2 -
Slowly loosen the nut of the pressure reducer or the high pressure hose connected to the cylinder.
Verify that the cylinder pressure is zero. Remove the pressure reducer (or disconnect the high pressure hose
from the cylinder, if present). Check the condition of the gaskets between the reducer and the cylinder or
between the high pressure hose and the cylinder. If the gasket is deformed or cracked, call a specialist for
replacement.
3 -
Replace the CO2 cylinder, restore the connections, open it slowly and make sure there are no leaks
and then fully open the valve and check that the pressure values are those set initially.
Once you have replaced the cylinder, check that there are no leaks. CO2 is an asphyxiant gas, heavier than
air, and it tends to accumulate in enclosed areas (chapter ”4.5.6” pag. 35).
