Original instructions
2.
Containment-Enhancing Sash Handle
includes a perforated air passage
directly atop the handle to bleed air into the hood chamber and direct
chemical fume concentrations away from the user breathing zone. The large
radiused handle sweeps airflow into the hood with minimal turbulence.
3.
Large usable interior work depth and interior height of 48"
provides
ample working space and directs contaminants away from the operator.
4.
Opti-Zone™ Rear Downflow Dual Baffle System
directs horizontal
streams of airflow to the rear slots of the primary baffle in a single pass.
Baffles are removable for cleaning. The secondary baffle, located
between the primary baffle and the back wall, counteracts the upward air
streams that create roll in traditional hoods.
5.
Exterior access cover plates
are removable for easy access to plumbing
valves and sash adjustment hardware when servicing through the sides is
not possible.
6.
Lift-Away™ front panel
provides easy access to electrical wiring, sash
weights, and lighting fixtures.
7.
Energy efficient LED lighting
is located behind a laminated safety glass shield
mounted to the top of the hood. The factory-wired instant start T8 lighting is
serviceable from outside the hood cavity. Additionally, the long lasting 50,000
hour direct wired LED T8 bulbs are more energy efficient, utilizing
approximately ½ the power of fluorescent bulbs. See Appendix A for wattage.
8.
Low mounted, factory-wired light and blower switches
are ADA compliant.
9.
Eco Energy Conservation Air Foil and Flush Foil
allow air to sweep the
work surface for maximum containment. The perforated Clean-Sweep™
openings create a constant protective barrier from contaminants. In
addition, should the operator inadvertently block the airflow entering, the
air continues to enter from under the air foil and through the Clean-Sweep
openings. See Appendix A for alternate PVC Eco-Air Foil as PVC
material resists corrosion from mineral acids.
10.
Streamlined corner posts
provide maximum visibility and the flexibility
to add services after installation.
11.
All hoods are factory prepared for up to 8 service fixtures
.
12.
Duplex electrical receptacles
are mounted on the right and left corner
posts as requested. Receptacles are factory-wired to hood single point
junction box.
13.
Upper Dilution Air Supply
(not shown) provides bypass air from above
the work area. This feature constantly bathes the sash interior with clean
air and reduces chemical fumes along the sash plane, near the critical
breathing zone. The upper dilution air supply perforations sweep the
upper interior to reduce stagnant pockets of air in the upper interior.
14.
Shipped fully assembled
and eliminates the need for costly onsite
assembly. If needed, the fume hood easily breaks down for transport
through doorways.
