Never operate the pump with suction valve closed.
2.
Never operate the pump with the discharge valve closed.
3.
Never operate the pump unless it is completely filled with liquid and vented.
4.
Never operate the pump unless an adequate liquid source is available.

3.13 Pre-Operational Checks
The following steps should be followed at initial start up and after the equipment has been
overhauled:
1.
Prior to installing the pump, flush the suction side of the system to remove all deposit (slag,
bolts etc).
2.
Ensure the pump and piping is clean. Before putting the pump into operation, the piping
should be thoroughly back flushed to remove any foreign matter which may have
accumulated during installation. Take all possible care not to contaminate your system.
3.
Install suction strainer. (
See Section 2.15
).
4.
Fill the bearing housing with the appropriate oil to the correct level.Bearing must receive a
small amount of oil prior to starting to ensure adequate lubrication at start up. (Refer to
Section 4
).
5.
Turn pump rotor by hand or with a strap wrench to make sure it turns smoothly.
6.
Assure that correct seal piping has been installed and has not been damaged.
7.
Prior to coupling installation, bump start motor to check for correct rotation. If rotation is not
correct refer to motor manual for appropriate connections to change rotation (Shut down all
power prior to change).
8.
Ensure coupling is correctly aligned and lubricated, and pump and driver is satisfactorily
dowelled. (Refer to
Section 2.6
).
9.
Ensure coupling guard is correctly installed.
WARNING
The unit must not be operated unless coupling guard is securely and completely bolted in
place. Failure to observe the warning could result in injury to operating personnel.
10. Check torque of all bolting and the plugs for tightness.
