OVERVIEW
These Structural Concepts merchandisers are
designed to merchandise packaged products at 41 °F
(5 °C) or less product temperatures (unless custom
cases with wire rack shelving).
Product must be pre-chilled to 41 °F (5 °C) or less
prior to being placed in merchandiser.
Cases should be installed and operated according to
this operating manual’s instructions to ensure proper
performance.
Improper use will void warranty.
TYPE
This unit is designed for the display of products in ambient
store conditions where temperatures and humidity are
maintained within a specific range.
For Type 1 Conditions (most cases): ambient
conditions are to be at 55% maximum humidity and
maximum temperatures of 75 °F (24 °C).
For Type 2 Conditions: ambient conditions are to be
at 60% maximum humidity and maximum
temperatures of 80 °F (27 °C).
If unsure if unit is Type 1 or 2, see tag next to serial
label. See SERIAL LABEL LOCATION &

PRECAUTIONS
Following are important precautions to prevent
damage to unit or merchandise.
Please read carefully!
See previous page for specifics on OVERVIEW,
TYPE, COMPLIANCE and WARNINGS.
CAUTION! LAMP REPLACEMENT GUIDELINES
Fluorescent lamps have been treated to resist breakage and
CAUTION

LED lamps reflect specific size, shape and overall design.
Any replacements must meet factory specifications.
CAUTION! GFCI BREAKER USE REQUIREMENT
If N.E.C. (National Electric Code) or your local code
requires GFCI (Ground Fault Circuit Interrupter) protection,
you MUST use a GFCI breaker in lieu of a GFCI receptacle.

CAUTION! CASES WITH POWER CORD AND PLUG
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT covered
by warranty.
End panels must be tightly joined or kept at least 6-inches away from
any structure to prevent condensation.
Unit must be kept at least 15-feet from exterior doors, overhead HVAC
vents or any air curtain disruption to maintain proper temperatures.
Unit must not be exposed to direct sunlight or any heat source (ovens,
fryers, etc.).
Tile floors, low ceilings or small rooms will increase noise level.
Whisper Cool compressor blanket or remote unit may resolve noise
level issues.
Keep at least 8-inch clearance above unit for air discharge
(self-contained units only).
WARNING
Overflow Condensate Pan Heater Rod Is Hot!
Electric condensate pan must be disconnected and allowed
to cool before cleaning or removing from case.

INSTALLATION: REMOVAL FROM SKID, REMOVING LOWER FRONT PANELS
1. Remove Case From Skid
Remove shipping brace that may be
securing case to skid.
Support case to prevent tipping.
Caution! Rails can be damaged if case hits
floor with heavy force!
Carefully slide unit to
rear of skid and tip
backward off skid.
Illustration may not
reflect every feature
or option of your
particular case.
Slide Skid Out
Case can be repositioned with pallet truck when
front lower panel is removed. Blocking may be
necessary to obtain adequate height.

2. Remove Case From Skid (Casters)
Remove shipping brackets that may be securing
casters to skid
Place ramp up against skid (to allow case to
smoothly slide off from skid).
Maintain support of case at all times or center
of gravity may cause case to fall.
Unlock Casters. Roll unit to rear of skid.
Roll down ramp
and off from skid.

INSTALLATION, CONT’D: BOLTING and CAULKING UNITS TOGETHER
4. Bolting and Caulking Units Together
Follow these steps to assure a secure, level lineup.
A. Begin all lineups leveling from highest point of
floor.
B. After the ’first’ case is level, apply industrial grade
butyl caulk on non-visible areas (at case end).
Use industrial grade silicone sealant on visible
areas (at case end).
C. Form Two (2) Caulk/Sealant Lines
: (Sanitation
and Refrigeration). See illustration at mid-right for
outline of caulk/sealant lines.
D. Line up ‘second’ case bolt-hole to bolt-hole to
‘first’ case.
E. Using SCC-supplied bolts (found in installation
packet), insert bolts in bolt hole locations (shown
at right). You may need to remove decking to
access lower bolt holes.
F. Caution! Front of cases MUST be flush with each
other! After leveling, all cases to be same height.
G. Using SCC-supplied nuts & bolts, lightly tighten
each of the 5 to 8 bolts in a cross-wise pattern.
Work your way around the pattern, tightening
more firmly at each pass. Do not
firmly tighten
one bolt and then start on the next!
H. After the cases are bolted together, level the
‘second’ case. Repeat this process for each case
to be adjoined.
I. After all lined-up cases are level, seal all seams
with industrial grade silicone sealant.

Note: Unit shown may not exactly reflect every feature or option of your particular unit.
5. Position & Align Case Alongside Other
Cases
Before adjusting levelers (or shimming frame
support rails), make certain that the case is in
proper position and, if required, aligned with
adjoining case.
This may require the repositioning of the case
you are installing or

case adjoinments routinely consist of end panel
removal for case-to-case placement.
the already positioned case.
6. Frame Support Rails Must Be Shimmed
Illustration below shows case with frame
support rails.
Shims will be provided with all cases that have
frame support rails.
Use shims to level case.
Note: After case is in position, it must be
sealed to floor to prevent entry or leakage
of liquid or moisture.

INSTALLATION, CONT’D: FRONT GLASS ALIGNMENT & ADJUSTMENT (VIA RAIL SYSTEM)
T
7. Front Glass Alignment & Adjustment via Rail System (For Curved and Flat Front Glass)
Proper alignment of the front glass is important to create and maintain a seal inside the case.
Improper alignment can cause air leaks compromising the environment inside the case and create condensation.
Follow the five steps listed below to assure proper front glass alignment.
Illustrations shown may not exactly reflect every feature or option of your particular case.
1. Side-to-Side Leveling
to front glass). Raise or lower either side of case by inserting shims
under the rails to level the case (following steps 3 and 4 below).

Front Glass
Rails
: Place a level on top of display case (parallel
2. Front-to-Back Leveling
Place a level on top of case,
perpendicular to the front glass.
Raise or lower either side of case
by shimming under the rails
(following steps 3 & 4 below).
Double-check the side-to-side level.

5. Verification:
After inserting shims, open and shut the front glass.
Verify (again) that the front glass is properly aligned at both left-hand and right-hand side of
the case.
If not, repeat the shimming procedure until the front glass is properly aligned along both sides
of the case.
