Covered in my OW class a decade ago. Both the inflator hose dump and the rear dump.
There’s really not much more than about 5 minutes worth mentioning really. You pull the knob in the rear if you’re head-down or on a plane and you pull the inflator hose if you’re head-up.

How it works and how to take it on and off is more the PADI Equipment Specialist course.
