8.1 Motor Rotation Procedure Caution: Motor is heavy!
Caution: If system is lled and pressurized, shut o valve before and after the 00e. Allow to cool if system uid 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 lling and pressurizing. If the
pump is installed and the system lled / pressurized prior to rotating, system
uid will leak out of the motor/volute when the allen screws are removed.
Ensure the pump is bled of uid 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 at bladed screwdriver slightly loosen the motor,
then rotate. If all else fails completely remove the motor and reinstall in
the desired conguration.
• 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 lling 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.
