* Asterix means that this is the closest correlation between the two systems, but is not exactly the same thing eg. slightly different line position.
Helium Pump Switch Box
The new ICE box unlike the IGH doesn't have the capability to switch ON/OFF either the He4 or He3 pumps inbuilt, hence a separate switchbox had to be designed to account for this.
