Operation
5.3 Pump Rotation
1. It will be necessary to operate all pumps in variable speed to check for proper rotation.
2. Place the TechnoForce into operation as described in previous sections.
3. Run each pump in auto noting rotation in each.
4. If rotation is wrong, exchange the wiring on two motor phases.
NOTE: Changing phase at VFD input does not change output phasing.
DANGER:

to servicing pumps. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS
PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
