OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / CORDS / WIRING - PG 1 of 2
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).
Products 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 1 vs. TYPE 2 CONDITIONS
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).
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 &
INFORMATION LISTED / TECH INFO & SERVICE
section in this manual for sample serial labels).

PRECAUTIONS
Following are important precautions to prevent
damage to unit or merchandise.
Please read carefully!
See previous page for specifics on OVERVIEW,
CONDITION TYPE, COMPLIANCE and WARNINGS.
CAUTION! GFCI BREAKER 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
Performance issues caused by adverse conditions are NOT cov ered by
warranty.
End panels must be tightly joined or kept at least 6-inches
structure to prevent condensation.
Unit must be kept at least 15-feet
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
units only).
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES

CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
WIRING DIAGRAM FORMAT & LOCATION
Each case has its own wiring diagram folded and in its own packet.
Wiring diagram placement may vary; it may be placed near ballast box, field
wiring box, raceway cover, or other related location.
CAUTION! CHECK CONDENSATE PAN POSITION & PLUG
Water on flooring can cause extensive damage!
Before powering up unit, check and confirm the following:
Condensate pan must be DIRECTLY UNDER condensate drain.
Condensate pan plug must be securely plugged into receptacle.
Overflow pan must have plug connected to its box. Units with
optional Clean Sweep™ MUST HAVE 2 plugs connected.

2. Remove Case (With Levelers or Frame Support
Rails) From Skid
To prevent damage, support case while sliding it
toward edge of skid.
When case is at edge of skid, carefully lower to
floor so that two levelers (or one frame support
rail) rests on floor.
Carefully slide skid out from under case.
After case is off skid, place into position.

INSTALLATION: POSITIONING / ALIGNING / FRAME SUPPORT RAILS / LEVELERS
Note: Units shown may not depict an exact representation of your particular unit being installed.
1. 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.
2. Cases With Frame Support Rails: Shim
Illustration at top right shows case with frame
the already positioned
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.
3. Cases With Levelers: Adjust Levelers
After case is in position, adjust case so it is level
and plumb (see illustration at right).
You may need to remove front and/or rear

INSTALLATION, CONTINUED: BOLTING & CAULKING UNITS
4. Bolting & Caulking Units Together
Note: Unit shown may not depict an exact
representation of your particular unit being installed.
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 below for
outline of caulk/sealant lines.
D. Line up ‘second’ case bolt-hole to bolt-hole to
‘first’ case.
Approximate hole

E. Using SCC-supplied bolts (found in packet),
insert bolts in bolt hole locations (shown below).
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.
