Original instructions
12. One duplex electrical receptacle is mounted on the right corner post.
Receptacles are factory-wired to hood single point junction box.
Additional electrical receptacles are available as factory or field installed.
13. Type 316 Stainless Steel interior liner is seamless with coved interior
corners and integral work surface.
14. Accessory Guardian™ Digital Airflow Monitor or Guardian Jr.
Monitor continuously monitors face velocity. An audio/visual alarm alerts
the user to low airflow conditions. The right corner post is factory
prepared to accommodate the Guardian Monitor (sold separately).
15. Optional Energy-Reducing A-Style Combination Sash Models. These
combination sashes allow the operator to use the hood with sashes either
half open vertically or horizontally to conserve energy. Optional sash stops
prevent raising the vertical sash above the half-open and fully closed
positions unless manually defeated by the operator.
16. Outside frame of epoxy-coated steel and galvanized steel is durable and
corrosion resistant.
17. Exhaust connection. The hood features 11" (11.00" OD pipe) Type 316
Stainless Steel exhaust connections sized to allow for a minimum static
pressure loss through the hood structure while providing a good transport
velocity through the exhaust system.
18. Solid hardboard support provided to support the integral Type 316
Stainless Steel bottom.
19. Optional Ceiling Enclosure Kits are available for a decorative facade
between the hood and the ceiling.
20. Optional Sash Stops provide a means of controlling the operating height
of the sash.
21. Washdown control fixture. Located on the left hand side of the hood
superstructure, this valve controls the water flow to the integral washdown
spray nozzles. The nozzles are located behind the hood baffle and
washdown areas in the hood, which are inaccessible without removing the
baffle. The control fixture can also be set up to control the washdown
system used in your exhaust ductwork. To do this, connect the water line
from your external washdown system to the plugged connection provided
on the top of the internal washdown assembly. For additional washdown
valves and sizing, See Chapters 2 & 7.
22. Built-in Upper Bypass. The Perchloric Acid Hood includes an upper
bypass block which proves to be useful when working with heat in
digestions.
