8.1 Motor Rotation Procedure Caution: Motor is heavy!
Caution:
If system is filled and pressurized, shut off valve before and after the 00e. Allow to cool if system fluid is hot.
8.1.1 Motor Rotation Procedure
The factory default orientation of the Volute and Frequency Drive has the
bottom of the VFD and the pump inlet at the 6:00 position, motor shaft
horizontal. The following is the procedure is the VFD needs to be rotated.
IMPORTANT NOTE:
It is highly recommended motor rotation occurs prior to
installing. If the pump is installed, rotate prior to filling and pressurizing. If the
pump is installed and the system filled / pressurized prior to rotating, system
fluid will leak out of the motor/volute when the allen screws are removed.
Ensure the pump is bled of fluid prior to rotating, then purged of air
prior to powering back up.
• In a cross pattern, loosen and remove the 4 allen screws holding the
motor to the volute.
• With your hands, rotate the motor to the desired position. In the event the
motor will not rotate, using a flat bladed screwdriver slightly loosen the motor,
then rotate. If all else fails completely remove the motor and reinstall in
the desired configuration.
• Ensure the Volute O-Ring is placed in the volute, between
the rotor assembly and the volute.
• In a cross pattern, tighten the 4 allen screws.
• Recommended to test run prior to filling and pressurizing system
(an E10 Low Load / Dry Run error will occur after 20 to 30 seconds of dry
running – temporarily dry running will NOT damage the pump).
If an E11, E24 occurs remove the motor and inspect the impeller for evidence
of binding in the volute. Re-align, reassemble and re-test.
