Hi there!
Apple’s App Store Connect Help states the following for App Units:
App Units
The number of first time purchases of your app made on the App Store on devices running macOS 10.14.1, iOS 8, or tvOS 9, or later. An app unit is counted when a customer taps the ‘Get’ or ‘Price’ button for the first time.
App updates, downloads from the same Apple ID onto other devices, and redownloads to the same device are not counted. Family Sharing downloads are included for free apps, but not for paid apps.

If users already bought or downloaded the app for free, they get tagged as “Installations” when they redownload the app.
We once tested this for a campaign with friends who didn’t bought the app yet. As expected exactly after the 5 purchases (aka App Units) the campaign appeared in ASC.
The answer is a little late, but maybe it helps someone.
