Before I removed anything, I'd check with my dealer. Obviously they didn't do a very good pre-delivery walk thru
Hope this helps... My Alpine has the HP in the rear a/c, but the operating principal should be similar. You may have a different model, but they should give you an overview.
Dometic also has a web site.

Good Luck, and WELCOME!
