Connection of the High Vacuum Flange
If the rotor stops suddenly, the resulting torque must be absorbed by the hardware
fastening the high vacuum flange.
Bolts or hardware must meet the specification below.
WARNING
It is mandatory to connect the pump in such a way to withstand the torque
specified in the "INSTRUCTION FOR USE" section. Specifically pay
attention to clamp design, material of clamps and bolts and bolt fixing
torque.
Use only high resistance class clamp s (or bolts) ≥ 8.8.
WARNING
If the pump is fastened on a vacuum chamber with flanges different
from those recommended by Agilent, there is the chance of the
TwisTorr 305-ICQ & 305-IC SF twisting or tearing-off in case the rotor
suddenly stops. The combination of different flange types is not allowed.
Agilent will not accept any liability for all damages resulting from improper
fastening.
