During operation, the following environmental conditions must be
respected:
In the presence of magnetic fields the pump must be protected using
a ferromagnetic shield. See the appendix "Technical Information" for
detailed information.
The TV 401/301 MS must be connected to a primary pump (see
"Technical Information").
The TV 401/301 MS can be installed in any position. Fix the TV
401/301 MS in a stable position connecting the turbopump fixing
flange to a fixed counter-flange capable of withstanding a torque of
2000 Nm around its axis.
The following table shows the screws to be used to fix the
turbopump, the necessary number and the relevant fixing torque.

WARNING!
The vacuum chamber that contains the Turbopump must have an adequate
thickness for safety requirements. For example, a thickness of 5 mm is
adequate for an hardened Anticorodal chamber (σ
