Hanging the Back Supply Plenum
5.Hang the back supply plenum from the ceiling.
(The back supply plenum needs to be mounted 31.25 in. (79.375 cm) above the floor (based upon a canopy hood that will be hung at 78 in. (198.12 cm) above the finished floor. This is measured from the lowest rear edge of the back supply plenum to the finished floor. Leave 6 to 10 in. (15.24 to 25.4 cm) of space below the plenum for access to the air diffusers.)
6.Fasten the Back Supply to the wall, going through the lower Back Supply wall. (Fig. 15)
•These fasteners are to help maintain the location of the Back Supply, and are not intended to hold the weight of the Back Supply Unit.
•The fasteners should not interfere with the removable air diffusers.
•The 31.25 in. (79.375 cm) height is based upon the canopy hood hanging height of 78 in.
(198.12 cm) from the finished floor to the bottom of the hood.
