Hanging The Hood; Air Diffusers - Greenheck 452413 Installation, Operation And Maintenance Manual

Hanging the Hood

Before hanging the hood according to the
hood installation instructions, please check the
following:
1. Make sure the back supply plenum is
properly secured, as described in steps 5
and 6, page 10.
2. If the ductwork for the back supply 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 5 for instructions.
4. Lift the hood, and position it so the filler
panels are resting lightly on the top outside
edges of the back supply. The back supply
is used to position the hood only, it is not
intended to hold any hood weight. (Fig. 16)
5. Connect the remaining ductwork for the
back supply and the hood. It is recommended
that caulk be applied at the mating seams
and surfaces of the back supply, the hood,
and the wall.

Air Diffusers

The air diffusers, located at the bottom of the back
supply (Fig. 17), will need to be cleaned as often as the
Canopy Style Hood
application dictates. Inspect periodically to determine
the cleaning schedule.
1. To clean the air diffusers, unfasten the screws.
Remove the air diffusers from the Back Supply
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. (Fig. 18)
3. Refasten with the stainless steel screws.
