Brink Pure Induct - orientation

[I N]

Is anyone here familiar with Brink Pure Induct? Is there a restriction on installation orientation.

I would like to install it vertically - looking at the manual, it doesn't say either way but video shows horizontal installation.

It can be rotated on its axis, to gain access to the filter, but I can't see anywhere where it states ( either way ) that it is orientation dependant. I suppose this would be a question for Brink Tech Support.
