4.7 Check the impeller rotation
CAUTION: Crush Hazard
The starting jerk can be powerful. Make sure nobody is close to the unit when it is started.
If the propeller rotates in the wrong direction, then the pump lifts up and rotates, which can
damage the cables.
1. Start the motor.
2. Stop the motor after a few seconds.
3. Check the direction of rotation.
The correct direction of propeller rotation is counterclockwise when viewed from the
propeller end of the unit.
