  • Page 16 Filling the Inert Gas Supply Tank The inert gas being used to pre-charge the LS-14 must be compatible with the seals in the LS-14. Welker recommends using nitrogen or helium as the inert gas supply.     The relief valves and gauges must be adequate for the pressure used to pre-charge the LS-14.
  • Page 17 Check all connections between the inert gas supply tank and the receiver cylinder for leaks. Repair as necessary.  25. If the LS-14 will use pneumatics for mixer actuation, proceed to step 37. If the LS-14 will use hydraulics for mixer  26.
