Packing List
Preparation
1. Place, level, and install the Base Unit Assembly that will support the Fume Hood as shown on page 4.
2. Attach the Fume Hood Worksurface to the Base Unit Assembly at the corners using epoxy cement or similar adhesive.
Worksurface should be centered on units and overhang the front by 1/2". Worksurface must be level.
Shim as needed. Top should extend all the way to rear wall.
3. Uncrate Fume Hood taking care to sort and inventory all parts.
4. Remove End Panels from Fume Hood (by lifting up and out) and remove screws anchoring Weight Box to Fume Hood.
5. Remove all packing from Fume Hood and any tape holding parts in place for shipping.
Fume Hood is packed fully assembled except for Lower Airfoil. The Top Front Panel, may be
removed (by lifting up and out) to fit through narrow doorways and/or for easier access.
Generally electrical fixtures and plumbing fittings are shipped installed, but may be shipped loose
depending on job requirements. Fittings may also be pre-wired and/or pre-piped. Fixtures are not
shown on assembly diagram as quantities and locations vary to meet individual requirements.
Installation
6. Check that Sash Belts are properly routed over front pulleys, and engage rear pully sprockets.
7. Check sash auto-sash return height and adjust as needed. (See Auto-return Adjustment Instructions on page 5)
Handle Frameless Sash with care - Laminated Safety Glass will crack if abused.
9. Using as many workers as needed, lift assembled Fume Hood and place on leveled Worksurface being careful not to spread
bottom of hood. Make sure hood is pushed back as far as possible and centered on Base Unit Assembly.Check End Panels for
plumb and square.
10. Attach Lower Airfow to the Worksurface and Fume Hood using the included hardware as shown in Detail 1. Check that Lower
Airfoil is straight and level.
11. Coordinate connections of service fittings, electrical fixtures, and ductwork with the respective trades (i.e. mechanical, electrical,
HVAC). After connections are complete, replace interior Access Panels, if removed, and the exterior End Panels.
12. Check Sash again for level, smooth movement, and auto-return. Adjust as needed.
To level, loosen the two (2) set screws on one of the rear Sash Pulleys (see Figure 2), level sash, then retighten set screws.
13. Inspect the complete installation, remove any dust, dirt, or other debris. Check all moving parts for proper operation, and adjust
or lubricate as necessary.
Rear Baffles may be removed for cleaning by removing the two Baffle StandoffKnobs and lifting up
and out on the baffle panels.

Installation Instructions
Base Unit Assembly
for Bench Type Fume Hoods
Preparation
1. Locate and mark hood and base cabinet locations making sure area is clear of obstructions
and debris. Be sure all conduit, duct work and service lines have been run and are ready for
final connections.
Kemstruts and other pipe or worksurface supports should be installed before the
base cabinets are moved into place.
2. Locate the high point of the floor within the area that the base cabinets will be installed.
Installation
3. Starting with the base cabinet on the highest point on the floor, move the first cabinet into
location as shown in Detail 1 and according to project drawings.
4. Using a four foot carpenters level, level the cabinet; side-to-side, front-to-back, and diagonally.
(see Detail 2S and 2W to the left for leveling methods)
Blocks or cleats may be used to fasten cabinets to floor or walls to insure cabinets
don’t move during installation.
5. Move the next cabinet into position and clamp it to the first cabinet, making sure that the
cabinet faces and tops are flush.
6. Level the cabinet, as in step 4.
7. Using four (4) screws, as listed below, fasten the two cabinets together at all four corners of
the end panels.
Use #8 x 1-1/4" Flat Head screws for wood cabinets.
Use #8 x 1/2” Truss Head Sheet Metal screws for steel cabinets.
(pilot holes must be drilled in the steel cabinets before driving screws)
8. Complete hood installation and all mechanical connections before installing any required
fillers or scribes.
It is recommended that the polyethylene liner be removed from Acid Storage
cabinets during installation to allow fastening to adjacent cabinets and ease
plumbing connections. Be sure to replace when installation is complete.

Auto-return Adjustment Instructions
1. Set sash at specified maximum safe open position (factory default is 18”) and secure in place.
2. Loosen the (2) two set screws on the Auto-return Pulley.
3. Without rotating the Axle, rotate the Auto-return Pulley until the Auto-return Weight is at its lowest point.
4. Tighten the (2) two set screws on the Auto-return Pulley and release the sash.
5. Test the system.
Troubleshooting
If the sash is raised above the maximum safe open position and, when released, it does not return to the maximum safe
open position, then remove weight from the Sash Weight Box until the system works correctly. This increases the ratio
of the weight between the auto-return weight and the sash weight.
If the sash is below the maximum safe open position and, when released, it rises to the maximum safe open position,
then remove weight from the Sash Weight Box until the system works correctly. This decreases the overall
counterweight.
In either of the above situations, the weight should be removed in small increments. If it is necessary to remove enough
weight so that the sash closes completely, it may be necessary to add to the Auto-return Weight.This can be done by
removing the eyebolt from the top of the Auto-return Weight, adding washers to the stem of the eyebolt, and
reconnecting it.
