2) When securing the inlet port flange with claw clamps

Refer to Table 3.2 for rotational torque.

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 all 8 screw-holes for legs or all 8

attached legs. Follow "CAUTION" on page 3-9 about legs and bolts for

securing the base.

For the claw clamp-type, use the required number of claw clamps as

specified in Table 3.3. Position the claw clamps evenly on the

circumference.
