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 11/2". Worksurface must be level.
Shim beneath as needed.
3. Uncrate Fume Hood taking care to sort and inventory all parts.
4. Remove End Panels from Fume Hood and remove screws holding Fume Hood and Weight Box to pallet.
(Save End Panel screws to reattach End Panel later.)
5. Remove all packing from Fume Hood and any tape holding parts in place for shipping.
Fume Hood is packed fully assembled except for Weight Box,Sash Panels, and Lower Deflector
Vane. The Light Fixture and Top Front Panel may be removed 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. Fittings are not
shown on assembly diagram as quantities and locations vary to meet individual requirements.
Installation
6. Install Glass Sash Panels per instructions on page 5.
7. Check that Sash Cables are properly routed over front pulleys, around rear pulleys, and through the Sash Adjustment pulleys.
(see Figure 2)
8. Attach Weight Box to cables using three (3) 1/4" -20 x 3/4" R.H. Bolt, Nylock Nut, and six (6) Flat Washers (bolt, nut, and washer
shipped attached to cable ends)
9. Loosen Sash Adjustment pulley bolts and slide pulleys as needed to level Lower Sash Assembly. Re-tighten when adjusted.
10. Adjust Turnbuckle and Eyebolt to align Upper Sash with Lower Sash.
10. Using as many workers as needed, lift assembled Fume Hood and place on leveled Worksurface. Make sure hood is pushed
back as far as possible and centered on Base Unit Assembly.
11. Attach the Lower Deflector Vane to the Worksurface using five (5) 1/4"-20 x 1/2" flat head machine screws with washers. Then
anchor Lower Deflector Vane to Facia Posts using two (2) #8 x 3/4" self taping screws.
12. 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. Cover screw
holes in End Panels with 3/4" Plastic Plug Buttons.
13. Check Sash again for level and smooth movement. Adjust as needed. (see Steps 9 and 10 above)
To adjust Upper Sash side-to-side, loosen screws on back of Sash Rail and slide the Cable Connectors as needed.
To adjust Lower Sash side-to-side, loosen screws on back of Sash Frame (4 each side) and slide the Sash Guides as needed.
When adjusting side-to-side, make sure sash frame edges clear the front pulleys.

FUME HOOD
Detail 1
Fume Hood Base Cabinet
Location
Detail 2S
Steel base cabinets are
leveled using the adjustment bolts located in the
cabinet base.
Detail 2W
Wood base cabinets are
leveled using wooden
shims, available at any
lumber yard or home
center.
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. Make sure the back of the cabinet is located 8” from the rear wall, as shown in
Detail 1 above, and in proper relationship to adjacent walls or equipment as shown on job
drawings and floor plans.
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.
