WARNING
High gas pressure - Danger of bursting!
Exceeding the permissible filling pressure can cause the pole columns to burst, resulting in
severe personal injury and damage to property.
The filling device must include a safety valve (operating pressure 8.0 bar). The safety valve prevents
the pressure compartments from being overstressed due to an impermissibly high pressure.

Gas filling device W423
To pour in gas, connect the hose of the filling device to the filling flange W1 of the pole (Fig. 54 and Fig. 55).
Using the handwheel on the control valve, regulate the gas flow to prevent possible freezing of the cylinder.
Monitor the filling process on the precision pressure gauge.
Care must be taken that the filling pressure, which depends on the ambient temperature (see rating plate with
information about the filling pressure at 20°C), is correct.
