exhaust connections

Hi,

I'm a consulting Engineer and have a couple of questions regrading the connection of the forepump exhaust to the fume hood exhaut system for venting.  The installation guide says to run down then horizontal with the 1" hose provided with the Q-Exactive equipment.  Can I then rise vertically with the 1" hose after the "trap" has been created to connect to my fume hood exuast system tap located at the ceiling?  Please help.

Thanks
