Installation
Location
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature and
humidity are maintained at or below 75°F and 55% relative
humidity. DO NOT allow air conditioning, electric fans, ovens,
open doors or windows (etc.) to create air currents around
the merchandiser, as this will impair its correct operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from the
time the product is received, through storage, preparation
and display, the temperature of the product must be
controlled to maximize life of the product.
Uncrating the Stand (If Provided; Crating is Optional)
Place the !xture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the case
from the skid. The !xture can now be lifted off the crate
skid. Lift only at base of stand!
When crating is not provided, lift at one end panel using
forklift and place a dolly under that end panel such that
end panel rests in the middle of the dolly. Repeat the
same procedure at the other end panel. Once the !xture
is on dollies, move it carefully out of the truck. This is a
recommendation only. Unloading the !xture following safe
procedures is the responsibility of the company unloading
and installing these !xtures.
Exterior Loading
These models have not been structurally designed to
support excessive external loading. Do not walk on their
tops; This could cause serious personal injury and damage
to the !xture.
Setting and Joining
The sectional construction of these models enable them to
be joined in line to give the effect of one continuous display.
A joint trim kit is supplied with each joint.
• DSFI/N glass is shipped loose to job site due to tip hazard.
• Cases must be set and joined prior to installation of front glass.
• High risk of injury if glass is installed prior to finalizing installation.
• Case front tipping hazard if warning not adhered to.

5
Leveling
IMPORTANT! IT IS IMPERATIVE THAT CASES BE
LEVELED FROM FRONT TO BACK AND SIDE TO SIDE
PRIOR TO JOINING. A LEVEL CASE IS NECESSARY
TO INSURE PROPER OPERATION, WATER DRAINAGE,
GLASS ALIGNMENT, AND OPERATION OF THE HINGES
SUPPORTING THE GLASS. LEVELING THE CASE
CORRECTLY WILL SOLVE MOST HINGE OPERATION
PROBLEMS.
NOTE: A. To avoid removing concrete flooring, begin lineup
leveling from the highest point of the store floor.
B. When wedges are involved in a lineup, set them first.
All cases were leveled and joined prior to shipment to
insure the closest possible !t when cases are joined in
the !eld. When joining, use a carpenters level and shim
legs accordingly. Case must be raised correctly, under legs
where support is best, to prevent damage to case.
1. Check level of "oor where cases are to be set.
Determine the highest point of the "oor; cases will
be set off this point.
2. Set !rst case, and adjust legs over the highest part
of the "oor so that case is level. Prevent
damage - case must be raised under leg or by use
of 2x6 or 2x4 leg brace. Remove side and back leg
braces after case is set.
3. Set second case as close as possible to the
!rst case and level case to the first using the
instructions in step one. The fronts of the cases
should be in alignment. Caution: do not use
connecting bolts to pull sections together.
4. Apply a thick bead of 2-part epoxy to adjoining
end panels as illustrated in the following diagram,
especially around bulkhead cutouts and screw
holes. Apply liberal bead of 2-part epoxy between
cases along bulkhead and up the rear discharge
(grey silicone). Do not use Permagum because this
does not allow cases to draw up tight, and therefore
leaves gaps at the joint.
DSF 4 &5

5. Bolt* sections together. Typical bolt locations are
illustrated below.
6. Attach bulkhead caps* with 2-part epoxy*.
7. Slide PVC collar* (23/8-3”) through bulk head at the
humidity system plumbing cut outs. Secure the collar
with 2-part epoxy. Seal joint with 2-part epoxy*.
Fill collar by encapsulating piping with expanding
urethane foam*.
Proper case joint sealing is
extremely important to
prevent water leaks.
ATTENTION
INSTALLER
8. Connect applicable electrical, refrigeration, water,
and drain lines. See respective chapters for more
detailed instructions.
9. After cases have been leveled and refrigeration,
electrical, and waste piping work completed, install
the splashguards. (see instructions in the “Finishing
Touches” section of this booklet).
Note: Seal the unit to the floor with an NSF Listed caulk or
equivalent
Corner Wedges
Corner wedges are attached via front and rear camlocks.
Use a 7mm allen wrench to turn the locks. Do not
overtighten# Join the top by using a joint bracket (included
in joint kit) with 3/8” bolts.
Joint Trim
After cases have been leveled and joined, and refrigeration,
electrical, and wasted piping work completed, install the
splashguards. Fasten along the top edge, or center, with
$10 X 3/3” sheet metal screws.

Bumper Installation Instructions
Step 1: Make sure the aluminum channel and end caps
are installed.
Step 2: Use silicone lubricant to help the
bumper slide into the channel.
Step 3: Starting on one end: while inserting the bumper,
push it up against the end cap to prevent
the bumper from shrinking after installation
(when it gets cold).
Step 4: As you insert the bumper into the channel with
one hand, pull the bumper toward you with
the other to open the inside lips. Slowly
apply pressure by rolling the bumper into
the track.

Operation Notes
• Always place both wings in the Down position before attempting to open and/or close the front glass.
• Securely close the front glass, then close side wings.
• Use care when placing wings in the Down position.
• The bumpers offer a reasonable amount of protection from impact, but will not endure excessive abuse.
• The wing is designed to accept pressure from the weight of the glass.
• Be sure that the glass seats properly on the Plexiglas stops to prevent the wings from falling over.
• Fine Tuning and adjustment of the Front Glass may be necessary to !t glass pro!le.
Front Glass can be adjusted per the recommendations on the following pages. Professional installation and
adjustment is recommended.

Glass Stop and End Wing Final Position Notes
End Wings and End panels from the factory should have pre-drilled holes for the plex post and wing channel
respectively.
If a hole has not been pre-drilled into the side plex and end panels, observe the following notes:
1) The glass stop post must be precisely located on the end wing. Refer to dimensions G and H on page 16.
2) The wing channel must be located and mounted precisely on top of the end panel. Refer to dimension F on page 16.

Installation (Cont'd)
Boston Series 2000
NOTE: Flexible top: Over cut vinyl 1/8" for every 4' section for
the flexible top to ensure a proper fit.
NOTE: Rigid Top: Do not over cut.
1. Attach the base and end/corner cap to the desired
surface by inserting #8 pan head screws through the
pre-slotted holes in both the end cap and the base.
Insert screws through the two holes of end cap and
tighten.
2a. Flexible Top: Butt end of the vinyl top against
end/corner cap. While applying pressure, bend
back vinyl top so that vinyl legs are positioned within
the base grooves. Roll vinyl top over full length of
base, then tap with rubber mallet to ensure vinyl is
securely locked into the base.
2b. Rigid Top: Snap the Rigid Top over the Rigid Base.
3. If necessary wipe clean with any household cleaning
product.
Helpful Hints:
● For best results, before cutting, install a scrap piece
of base into vinyl top to achieve a clean cut.
● Set the uncoiled flexible vinyl at room temperature
24 hours prior to installation.
● Lubricate the inside of the vinyl with soapy water or
silicone before installing.
● Over cut the flexible vinyl and compression fit.
Adding the additional materials will compensate for
stretching which occurs during installation.
