4 Filling of the nitrogen cylinder
4. Close the regulating valve at the pressure reducer and turn the pressure adjust-
ment valve for filling pressure back to minimum. Carefully open the nitrogen
bottle. The cylinder pressure and the nitrogen cylinder filling pressure can be read
on the manometers. Set the nitrogen cylinder filling pressure using the pressure
adjustment valve for filling pressure.
5. Open the regulating valve on the base body. Open the regulating valve on the
pressure reducer. The nitrogen cylinder will then be filled with the set filling
pressure. This pressure can be read on the base body’s manometer.
When the filling pressure has been reached, close the regulating valve on the
base body and then open the outlet valve.

After opening, the residual pressure will escape from the base body and the
filled nitrogen cylinder can then be unscrewed.
6. For other nitrogen cylinders that have to be filled with the same pressure, repeat step 5.
7. Following a functionality and tightness test, the nitrogen cylinders can be used
again.
8. For the tightness test, STEINEL Normalien AG provides a force measuring device.

9. The nitrogen bottle will be closed if no additional springs are filled. Then, open
the outlet and regulating valve on the base body, as well as the regulating valve
on the pressure reducer, in order to release the residual pressure. The charging
tubing can now be removed in a depressurised state.
4.2 Nitrogen filling pressure table
WARNING
The pressure values specified in this table correspond to the maximum
filling pressures. Only the specified filling pressure may be used during
filling. A higher filling may lead to damage or malfunctioning, and is
prohibited for safety reasons.
The relevant filling pressure is specified on the respective nitrogen cylinder and
must be obtained from there
(see labelling on the nitrogen cylinder).
