Hanging the Hood
Before hanging the hood according to the hood
installation instructions, please check the following:
1. Make sure the Backsupply Plenum is properly
secured, as described in steps 5 and 6, page 13.
2. If the ductwork for the Backsupply will not
interfere with the hood installation, it should be
connected now.
3. Any filler panels should be attached to the hood
before the hood installation. See page 16 for
instructions.
4. For Canopy Hoods: Lift the hood, and position it
so the filler panels are resting lightly on the top
outside edges of the Backsupply. The
Backsupply is used to position the hood only, it
is not intended to hold any hood weight. (See
Fig. 13)
5. Connect the remaining ductwork for the
Backsupply and the hood. It is recommended
that caulk be applied at the mating seams and
surfaces of the Backsupply, the hood, and the
wall.

Removable Air Diffusers
Air Diffusers
The air diffusers, located at the bottom of the backsupply
(See Fig. 14), will need to be cleaned as often as the
application dictates. Inspect periodically to determine the
cleaning schedule.
1. To clean the air diffusers, unfasten the screws. Remove
the air diffusers from the Backsupply Unit, and wash in
the sink or dishwasher.
2. Insert the air diffusers at an angle from the bottom, and
rotate so the forms are downward. Rest the diffuser on
the internal angles. (See Fig. 15)
3. Refasten with the stainless steel screws.
