Installation
1) When securing the inlet port with bolts
Refer to Table 4.2 for torque in pump abnormality and recommended securing bolts.
Secure the inlet port flange with all of the boltholes of the size specified in the Inlet
Port Flange Standard.
Secure the base with all 8 screw-holes for legs or all 8 attached legs.
Follow "CAUTION" on page 4-8 about legs and bolts for securing the base. Make
sure that the recommended securing bolt may be different depending on the method
of securing the base.
