GENERAL INFORMATION
Freight Damage
Repairing Paint Scratches
It is the buyer’s responsibility to inspect goods thoroughly for apparent damage before accepting shipment.
Please do not refuse shipment. Rather, if there is any apparent damage to the unit or packaging, please clearly
note that damage (in specific detail) on the bill of lading when accepting delivery. Failure to note apparent
damage on the bill of lading or another shipment document may prevent the purchaser and Lab Furniture and
Fume Hoods from successfully pursuing a freight-damage claim.
Please contact Lab Furniture and Fume Hoods immediately in the event of apparent shipping damage, or in the
event of damage discovered upon un-packing the product (i.e., concealed damage). Carriers often impose rigid
timelines for making a freight damage claim. Accordingly, failure to inspect the package upon receipt and/or
failure to contact Lab Furniture and Fume Hoods immediately upon learning of freight damage may prevent the
purchaser and Lab Furniture and Fume Hoods from successfully pursuing a freight-damage claim.

BASE CABINETS
Drawer Removal and Reinstallation
Drawers are installed at the factory before shipment. Drawers
are usually removed, however, during base cabinet installation,
and they must be reinstalled and adjusted to complete the installation.
This is accomplished as follows:
1. Remove drawers from the base cabinet.
Removing the drawer body from the slide assembly is easily accomplished,
without tools, by deflecting a nylon lever built into the innermost member of the
slide.
Steps:
A. Pull the drawer out to its full extension position and locate the black nylon levers on each side.
B. Push the black nylon lever up on the left side, and down on the right side, while pulling out gently on the
drawer. (Depending upon the slide manufacturer, the levers may need to be pushed in, rather than pushed
up and down.)
C. Pull the drawer body completely out of the slides, noting that the ball bearings in the slide align with and
travel in grooves. (Important: Take note of how the bearings engage in these grooves to lock the slide
members together.)
2. Install and level base cabinets, secure tops, etc. (see page 5 for leveling instructions)
3. Reinstall drawers, checking for proper alignment and fit.
To reinstall, pull the bearings all the way forward on the slides in the cabinet. Align the slides on the drawer
within the slides in the cabinet. Be careful to push the drawer in with equal pressure on both sides. The black
nylon lever on the slide attached to the drawer body will lock the drawer in place.
TIP: To save time adjusting the drawers to achieve proper gapping (see below), mark the drawers so they can be
reinstalled to their original locations.

4. If necessary, adjust drawers up or down.
You can adjust the drawer up or down if the gap at the top or bottom is uneven.
For cabinets with recessed fronts, the proper spacing around a drawer front is 0.125”
(1/8”) on all sides.
For cabinets with overlay fronts, the proper horizontal spacing between two drawer
fronts, or between a door and drawer front, is also 0.125”. For 35” high base
cabinets, the top gap/reveal is 0.575”, as shown below. The bottom gap/reveal is
0.65” for both 29” and 35” high base cabinets.
Steps to adjust drawers up or down:
A. Loosen the screws at the bottom of the drawer front.
B. Grab the drawer front and slide it up or down.
C. Tighten the screws and check for fit. Repeat if necessary.
Gapping for Base Cabinet with Standard (Inset) Fronts
Gapping for Base Cabinet with Overlay Fronts
Replacing Drawer Fronts
As noted above, in certain instances it may be necessary to replaced a damaged drawer front. This is easily
accomplished by the following steps:
A. Using a thin blade tool, pry out the nylon glides on the side of the drawer front. (Note: This step is not
applicable for casework with overlay-style drawer fronts, as those fronts do not have nylon glides.)
B. Use a Philips head screwdriver to remove the two screws at the bottom of the drawer front.
C. Pull the drawer front slightly outward and up to remove it from the drawer body.
D. Place the new drawer front on the drawer body.
E. Tighten the two screws at the bottom of the drawer front.
F. Push in the two nylon glides (inset-style drawer fronts only).
Loosen Screw to Adjust

G. Refer to the instructions above to adjust the spacing around the drawer front, if necessary.
Door Adjustment
Spacing of doors:
For cabinets with recessed fronts, the proper spacing around a door is 0.125” (1/8”) on all sides, as shown above.
The middle space (gap) between two doors is also 0.125”.
For cabinets with overlay fronts, the spacing between the outside of a door and the side of the cabinet (i.e., the
side reveal) is 0.0625” (1/16”). The vertical space between two doors, or between a door and a drawer front, is
0.125”.
Adjusting the door (hinge) up or down:
Each door can be adjusted up or down slightly for spacing purposes by loosening the hinge screws and moving
the hinge as necessary. Be sure to tighten the screws securely when finished.
Shelf Installation and Adjustment
Shelves are supported by adjustable shelf clips. Shelves are adjustable vertically in increments of 1.375”.
Steps:
A. Mount clips in each of the four corners at the desired height.
B. Tilt the shelf at an angle to place it in the cabinet, being careful not to scratch the inside of the cabinet.
C. At extreme shelf locations (top or bottom), it may be desirable to mount the rear clips first, then place the
shelf on them. Then install the front clips while holding up the front of the shelf.

Removing and Installing Back Access Panels / Bottom Panels
Base cabinets are equipped with removable back and bottom panels for access to wall receptacles and plumbing.
These panels are easily removed. (Note: Units with only drawers have an open bottom without bottom panels.)
Steps:
A. Empty the cabinet and remove the shelves.
B. Remove the cabinet bottom by lifting up at the back edge of the bottom, then tilt the bottom and remove it.
C. Locate the two bent tabs in the upper flange of the cabinet back. These tabs are bent at the factory to
prevent the cabinet backs from coming out of place during shipment. To remove the back panel, bend
these two tabs to a straight position, which will allow the cabinet back to slide upward.
D. Slide the back panel upward, then tilt the bottom of the panel forward and remove it from the cabinet.

Leveling
All base cabinets are equipped with leveling glides (“levelers”). While positioning and aligning the cabinets,
these levelers may be adjusted to accommodate uneven or sloping floors. A 0.125” (1/4") wrench or socket is
required.
There are four levelers in each base cabinet, one in each bottom corner.
Steps:
A. Remove all contents of the cabinet, including shelves.
B. Remove the cabinet bottom panel. Lift up at the back edge, then tilt and remove
(see above).
C. Use a ¼” wrench or socket to adjust the levelers.
D. Replace the cabinet bottom and shelves.

Installing Pull-Out Shelves
1. Insert the shelf bracket (back of cabinet).
A pull-out shelf is installed by first locating the white shelf bracket, choosing a height (start at the bottom first,
and work your way to the top), inserting the rear tabs into the rear return flange on the base cabinet. See photo
below.
2. Attach the shelf bracket to the front of the cabinet.
Line up the front-top of the bracket with the top line of the square knock out. Using a # 6 pan head sheet metal
screw, secure the front of the bracket to the base cabinet. The top line of the square knock out is for aligning
only; make sure to cover the top line of the knock out. Using this technique will verify that each bracket is
installed the same on all base cabinets.
See photos below (left photo shows the front of the bracket and the square knock out; right photo shows the
front-top of bracket lined up with the top line of knock-out and a # 6 pan head sheet metal screw being
installed). Repeat Step 1 & 2 for opposite side.
3. Locate slides and discard inner rail.
Locate the slides for the pull-out shelf and remove the inner rail. Fully extend the rail and press the black tab to
unlock the inner rail, while pulling the inner rail out. See photos below.

Discard the inner rail – this is not needed.
4. Install slide into the shelf bracket.
Install pull-out shelf slide to previously installed bracket by placing the slide into the bracket, using two #6 pan
head sheet metal screws. Install one screw into the front hole of the slide and the bracket (as shown below); the
holes in the slide and the brackets line up. Use the front hole on the front of the bracket and slide, and the front
hole in the back of the bracket and slide. Repeat this step for opposite side.
5. Install pull-out shelf.
Locate the pull-out shelf and line up the factory installed rail to the slides that were installed in step 4. See
photos below. Open and close the pull out shelf a few times to set the slides.

Sink Base Cabinets and Sink Support Assemblies
Sink base cabinets are factory-equipped to accept a variety of sink styles and shapes. The back of the cabinet is
open to allow access to plumbing and electrical services, and the cabinet sides are equipped with support channels
to provide attachment for sink support assemblies. Sink support assemblies are sold separately and consist of two
parts: threaded rod hangers and sink supports.
Sink supports are mounted using the threaded rod hangers. These hangers are formed at the top to hang on the
support channels that are on the inside (top) of the sink base cabinet. The hangers are extra long to allow for
varying sink depths. By adjusting the level of the nuts and washers at the bottom of the hangers, the sink
supports are raised or lowered to accommodate the sink.
The hangers should be adjusted and the sink should be in place before setting the counter top. Allow at least 1”
of clearance from the top of the sink to the top of the cabinet (i.e., the sink should be 1” or more below the top of
the cabinet).

Step B: Slide the inside corner filler into the filler clips.
Step C: Bend and attach the toe space filler.

15
ACID STORAGE CABINETS – VENTING
The back of acid storage cabinets feature two venting holes that are plugged with 2” hole plugs. In order to
function properly, acid storage cabinets must be vented to alleviate any corrosive fumes that may otherwise
accumulate inside the cabinet. It is the installer’s responsibility to ensure that venting is proper and adequate for
the intended use. Failure to vent a cabinet properly may cause corrosion of the cabinet and the cabinet hardware,
depending upon the types of chemicals stored in the cabinet.
PVC vent kits (sold separately) are designed to assist in the venting of acid storage cabinets. A vent kit fits
through the through the 2” hole in the back of the acid storage cabinet, as shown below. Acid storage cabinets
feature a removable back panel that also can be used for venting.

WALL CASES
The desired mounting height for wall case units may vary with each installation. To match floor case units, the
top of the wall case should be 84” above the floor. The installer is responsible for ensuring that the units are
securely fastened to the wall system.
Wall Case Installation
Each wall case unit is equipped with a separate “wall hanging bracket.” The upper, rear, horizontal frame
member at the back of each wall case unit is formed to slide onto this wall hanging bracket.
Steps:
A. The wall hanging bracket should be secured to the wall system at the proper height – 0.125” (1/8”) lower
than the finished height.
B. After the wall hanging bracket is securely in place, position the wall case slightly above the bracket and
flush against the wall. Gently slide the wall case down over the offset of the wall hanging bracket.
C. To ensure stability, screw or bolt the wall case (through the cabinet body) into the wall. The wall hanging
bracket is an alignment aid and support which must be supplemented with additional fasteners to prevent
the unit from accidentally being raised off of the bracket.
* CAUTION: Care should be taken when fastening the wall case to the wall (Step C). When tightening
the screws it is possible to collapse the back panel due to the cavity between the wall and cabinet back.
Install a filler block of wood in this cavity, where the fasteners will go into the wall, to keep the cabinet’s
back flat and free of dimples.
Step A: Secure the wall hanging bracket to the wall.
Step B: Slide the wall case onto the wall hanging bracket.
Step C: Screw or bolt the wall case to the wall.

sides, as shown below.
B. Install the sloping top by slipping the flanged edges of the top into the front filler clips.
C. Install the end caps on the right and left sides by slipping the flanged edges of the caps into (a) the filler
clips attached to the top edges of the wall case in Step A, and (b) the filler strips that are attached to the
underside of the sloping top.
Step A: Attach filler clip to the top of the wall case.
Step B: Slip the flanged edges of the top into the filler clips.
Step C: Install the end caps.
