that the structure can safely support the combined
weight of the fume hood and any related equipment.
The work surface should be at least as wide as the hood
to properly support it. The work surface is aligned
with the back of the fume hood. This will provide
the correct spacing under the air foil for proper
bypass airflow.
The following are instructions for mounting a cross
support:
1. Level the base cabinets and the work
surface. Work surface should be placed
flush with the back of the fume hood as
shown in Figure 3-1.
2. Scribe a line on the wall or back of the base
cabinet to locate the support under the work
surface.
3. Mount the support by attaching it to the wall
or base cabinet.
4. Place the hood on top of the work surface
and cross support.
The work surface should be smooth and durable, such
as a chemically-resistant epoxy resin. The surface
should be nonporous and resistant to the acids, solvents,
and chemicals used.
!
WARNING: It is important to support the rear of
the work surface and fume hood. The cross support
provides support for the bottom of the work surface.
Install the cross support after the base cabinets and
work surface are leveled and before installing the
hood.
