No Chris, you need to add a switch or some how switch the motor wires if you want to be able to change rotation direction.
As you can see in the photo I use three small wire connectors and just reverse the black and white wires to change direction.
I will replace the connectors with a switch sometime in the near future.
As the unit comes there is a plug and socket on the motor cable.
Unfortunately, it is the type of plug and socket that can be connected only one way.
To reverse motor rotation direction you will need to cut the plug out of the cable and replace it with a switch.

Inside the motor cable are three wires Black, White, Green.
The green wire is the ground and can be disregarded or wired green to green and left that way.
If the motor is wired white to white and black to black the motor will run in one direction.
If the motor is wired white to black and black to white the motor will run in the other direction.
