I just picked up a JDS AirTech 2000 air cleaner for my workshop. My shop is about 25' square with a motel style htr/ac unit (can't think of the correct name right now) just off center on one side, about 3' up from the floor. I'm going to mount the air cleaner on the ceiling. Which way should I mount this to get the best air flow to and from the unit? Perpendicular to the htr/ac, in which case it won't matter which way the air flow exhausts out of the unit? Or, parallel to the air flow of the htr/ac? And, if so, I would imagine it should exhaust away from the htr/ac? I was figuring on centering the air cleaner, but if I put it in line with the htr/ac, then should I off set it back away from the htr/ac about 2/3's of the ceiling length? Thanks. Greg
