It is a bit hidden and blends in with some of the other bolts. Below you will find the process from the manual that shows the drain plug location and the process for checking the fluid.

Basically you fill the unit until it comes out of the check/fill plug. Then you install this "check plug" and are finished.

Please let us know if you have other questions. Thanks
