Connecting the Gas Piping to The Pole Columns
REV7
/REV6
• Grease the threads of the gas couplings as per L4.
• Connect the gas piping to the pole column (to all pole columns).
Screw on the filling connection(s) (8) initially by hand, then tighten
provisionally using tool T022, and finally tighten using tool set
WK001. Tighten to a torque of 30 Nm. Use two wrenches for
connecting the filling connection(s).
• Retighten all couplings in the gas piping system.
We recommend that the gas cylinder be weighed before and af-
ter the filling operation and that the weight difference be compa-
red with the gas weight specified on the nameplate.
This makes it possible to verify that the filling process has been
carried out correctly.
