2) When securing the inlet port flange with claw clamps
When securing the inlet port flange with only the claw clamp, the vacuum equipment cannot
withstand the maximum rotational torque generated by the worst-case failure. To make the vacuum
equipment withstand abnormal torque, secure the base with either the 4 screws for legs or the 4
attached legs. Ensure instructions with regard to rotation stopper and bolts for securing the base are
adhered to page 33.
For the claw clamp-type, use the required number of claw clamps as specified in Table 7. Position
the claw clamps evenly on the circumference.
