Once the motor gets going, the vanes will flip over to the correct orientation. This is, however, forcing the vanes to flip over in a confined area. For peace of mind, it’s better to reinstall the impeller to the proper orientation.

An older impeller that has “taken a set” from being in the impeller housing for some time is a different story. The flipping over of those vanes could result in damage to or destruction of the impeller. This is why you should not turn a motor counterclockwise unless you plan on relacing the impeller.
