Welcome to the forum.
Didn't the compressor specific manual on the CD include break in info? Its a PDF file.
I just got the 5HP 60 Gal IR last month and the PDF manual from the disk told me to run it with the valve open for 30 minutes to break it in.
The paper book that came with it was generic safety stuff and info for all compressors and really didn't include break in info or any other model specific info.
The disk was attached to the back cover of the book. if you don't have it, give me your model number and I will look it up on my disk.
It should have come with IR synthetic oil, and if you buy the service kit (oil and air filters) IR will extend the warranty.
