Installation
A311-03-880 Issue A
After you have connected the drive/transmission or connected the electrical supply to the pump motor, check the
direction of rotation of the pump as follows:
1. If necessary (that is, to make it easier to see the pump drive shaft), temporarily remove any guard over the drive
coupling or belt (if fitted).
2. Refer to
. Watch the pump drive shaft (18) or the coupling (9) while you start up the pump (refer to
), then shut down the pump (refer to
) after two seconds or so.
3. Check that the pump drive shaft (18) or coupling (9) rotated correctly in the expected direction.
4. If the direction of rotation was incorrect:
If you have installed a bareshaft pump, check the installation of the drive and transmission system and
reconfigure as appropriate.
If you have installed an HV8000 pump with a motor, isolate the external electrical supply, then reverse any
two of the phase wires in the motor terminal-box.
Perform the direction of rotation check from
again, to ensure that the pump now rotates in the
correct direction.
5. If you have removed a guard over the drive coupling or belt (as in
above), refit the guard.
