The owners manual provided is very generic and of little value. This is because most of the components of an RV are supplied by OEMs and FR is simply an integrator who adds some walls etc. I suggest you make a list of the make model and serial # of all the OEM equipment on your unit then visit the manufacturers web site and download a users manual. This list will also be invaluable should you have issues or need to order parts in the future.
