How to publish a single book i OMP

At my institution we have an installation of OMP A new employee will work with it later this year. Now we have an urgent request to publish one single book within the next ten days. A pdf for publication is ready. But how do I get it through the editorial workflow. I don’t like in OJS find a quick submit plug in. And I dont’t find any user guides at PKP.

Could anyone give me a clue about what to do?
