Rotation direction (for threephase motors only).
ATTENTION A wrong rotation direction could damage the motor since in this case, the power draw of the pump will be much higher than that
forecast.
Check the exact rotation direction by proceeding with the following operations:
1) slightly tilt the pump to one side or hang it from a lifting means;
2) start the motor for a few seconds, making sure that the kick-back does not become a danger hazard;
3) if the kick-back has been anticlockwise viewing the electric pump from above, then the rotation direction is correct;
4) if the rotation direction is wrong, disconnect the power supply and reconnect the electric pump to the main by switching two of the three phases
with each other.
