Locate the interlock cable coming out from the opening circled in red in Figure 4-9 and connect it to
the interlock connector of the upper cooling block.
Note:
The upper cooling block is part of the radiation shielding design and as such it must be
connected to the head interlock circuit.

Cooling water supply and return
The hose that supplies the turbopump inside the x-ray head with cooling water is routed from the pump box
along the flex-hose assembly into the x-ray head through the opening circled in red in Figure 4-9. The return
hose is connected to the fitting of the upper cooling block circled in green in Figure 4-9. Both supply and return
hoses are plugged and stored inside the pump box during shipping. The labels attached to the hoses indicate
which hose connects to the turbopump and to the upper cooling block respectively.
The routing of the cooling water hoses depends on whether the system is configured left-handed, right-handed
or dual port. However, the cooling water should be routed to provide cooling to the subassemblies in the order
outlined by Figure 4-10.
