The manufacturer guarantees proper operation of the pump if it is used in a uniform magnetic field up to
0.5 mT. From 0.5 to 5 mT, proper operation depends on cooling and gas loads. A magnetic field ex-
ceeding 5 mT can cause excessive rotor heating. In this case, suitable shielding must be provided.
The standalone pump can withstand radiation levels of up to 10
3
Gy.
The turbomolecular pump cannot evacuate at atmospheric pressure; it must be connected to a
backing pump.
For a transient period, they can start to run at atmospheric pressure.
The turbomolecular pump can operate in any position.

1. Handling the pump, see chapter "Handling the pump".
2. Connect and secure the turbomolecular pump fastening to ensure operator safety and operational
reliability (see chapter "Installation specifications").
3. Stick the safety labels in the operator's language to the most appropriate and visible place on the
pump to warn the operator about potential hazards.

When handling the pump,
a lifting device appropriate for the weight of the product must be used
.
The weight and center of gravity vary depending on the model (see chapters “Technical data” and “Di-
mensions”).
1. Use 2 EN-1492-1 approved multi-strand staps that can support the weight of the pump.
2. Use approved accessories to attach the pump to the lifting device (e.g. hook with safety lock).
3. Position the straps securely around the pump.
4.
Position the lifting device hook vertically above the center of gravity.
5. Hoist up the pump and move it to its location on the frame.
6. Keep the pump hanged all the installation time until the high vacuum flange is secured.
