seeking advice on Suspending a Pollution Control Unit

[LSA]

I was giving the luxury of designing a grease exhaust system for a restuarant located below street level of a high rise building. After talking with the owner, it seems I need to design the pollution control system (Gaylord CleanAir) to be suspending in the ceiling plenum of the restuarant with an approved catwalk for servicing.
-Flr to Flr height is 15'-0"
-Ceiling height is no greater than 9'
-Gaylord Unit weight approx 2.5 tons
-Capacity = 5000cfm
-Dimension = 16'x6'x6' (LxWxH)

Anyhow the question is, does anyone have any experience with suspending hvac equipment of this size and weight? If so, what type of structural support base did u use? Where can I get more info on this appliation? Any info relating to supporting heavy HVAC equip would be appreciated.

Thanks Gentlemen!

I would hire a structural sub-consultant to determine what you require. Any failure of support would result in a huge liability issue.

you're right Walkes! Thats what we did.

Check Codes before you go too far. It may not be allowable to put the unit in the ceiling. The grease may catch fire.
