1 Check that the safety valve is operating properly by starting up the compressor with the end taps
turned off so that the pressure in the circuit rises quickly and the valve comes into operation at the
set pressure.
The valve is pre-calibrated in the factory at a pressure of 225 bar or 330 bar.
WARNING
Under no circumstances may the calibration pressure of these valves be increased. Any tampering
with the safety valves may cause serious damage to the machine or to persons and a cancellation of
the guarantee.
2 Check the condition of the cylinders to be filled.
If the cylinders should show evident signs of internal and/or external corrosion, it is not advisable to
proceed with the filling operation, even if they comply with inspection requirements.
Only use inspected cylinders provided with the relative approval.
The cylinder operating and filling pressure values are given on the cylinders themselves.
It is prohibited to exceed this refill pressure value.
