OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PAGE 1 of 2
OVERVIEW
These Structural Concepts G-Series® Service Single
Deck Refrigerated Cases are designed to
merchandise products at 41 °F (5 °C) or less product
temperatures.
Products must be pre-chilled at 41°F (3 °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 designed for Type 1 or Type 2
conditions, see label on case. Note
: Label locations
vary depending upon model.
COMPLIANCE
Performance issues when in violation of applicable
NEC, federal, state and local electrical and plumbing
codes are not covered by warranty.
See below compliance guideline.
WARNINGS
This page contains important warnings to prevent
injury or death.
Please read carefully!

OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PAGE 2 of 2
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
Fluorescent lamps have been treated to resist breakage
and must be replaced with similarly treated lamps.
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! 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
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
CAUTION
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).
CAUTION! CHECK CONDENSATE PAN POSITION & PLUG
Water on flooring can cause extensive damage!

label placement can sometimes vary depending upon model. See SERIAL LABEL INFORMATION
& LOCATION section in this manual for serial label samples.
Note 2. Dimensions of most models can be found at www.structuralconcepts.com. Simply enter
the case model number into the Product Number Search box. Click the product specification
link for complete dimensions.
Note 3. If your specific model is not found, contact technical service (phone number is listed at
Technical Service section in this manual) for dimensions.
Note 4. CDRs (Customer Design Requests) are listed with a 4-digit suffix. Dimensions are very
similar to standard model (pre-suffix) dimensions.

INSTALLATION: SKID REMOVAL / POSITIONING UNITS / ADJUSTING LEVELERS
Note: Units shown may not depict an exact representation of your particular unit being installed.
1. Remove Unit From Skid
Caution: Case must always remain supported
or center of gravity will allow case to fall.
Slide unit to rear of skid. Tip backward off skid.

3. Adjust Levelers
Certain cases (usually self-contained units)
Support
required
to prevent
tipping.
use levelers instead of rails.
If your case uses rails, see FRAME
SUPPORT RAIL SHIMMING section in this
manual (next page) for adjustment
instructions.
If your case uses levelers, you may need to
remove front or rear toe-kick to access them.
Use adjustable wrench to adjust leveler.
Depending upon case weight it may be
necessary to use a pry bar to accomplish
this task.
Do not use pry bar on
toe-kick as it may buckle.
Do not use pry bar on end
panel as it may chip.
Use pry bar ONLY on base
frame to avoid damaging
case.
See illustration and photos
at right.
2. Position & Align Case Alongside Other Cases
Before adjusting levelers (or shimming frame
support rails), check that case is properly positioned
and, if required, aligned with adjoining cases.
This may require the repositioning of the case you
are
installing or
the already

positioned
case.

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.

CASE ADJOINMENT: DISSASSEMBLY / SEALING UNITS TOGETHER
1. Rear Sliding Door / Wire Cover Removal
You must remove rear sliding doors to access
areas in uprights to adjoin cases.
You must also remove wiring cover to access
areas in uprights to adjoin cases.
Photo at right shows wiring cover to remove.
2. Sealing Units Together
A. Follow these steps to assure a secure, lineup.
B. Line up adjoining case (same model) bolt-hole
to bolt-hole to this case.
C. Level units from highest point of floor.
D. Either adjust levelers or shim the frame support
rails (depending upon construction of case).
E. Front of cases MUST be flush with each other.
After case is level, they are to be same height.
F. After the ’first’ case is level, apply industrial
grade butyl caulk on non-visible areas. You
may use industrial grade silicone sealant on
visible areas.
G. Form Two (2) Caulk/Sealant Lines
and Refrigeration). See illustration below-right
for outline of caulk/sealant lines.
H. If supplied both butyl and silicone, use butyl on
non-visible areas and silicone on visible areas.
Otherwise, urethane is acceptable for all areas.

placement, wiring cover reattachment and rear
door replacement.

CASE ADJOINMENT: SCREW PLACEMENT / WIRING COVER / REAR DOOR REPLACEMENT
1. Case Adjoinment: Screw Placement
A. Note
: Illustration at right and photo below is partially
disassembled for illustrative purposes only.
B. Screws to adjoin units are SCC-supplied.
C. After cases are properly leveled (or shimmed) and sealant
applied, units are to be adjoined with screws at the five (5)
locations shown in illustration (at right) and photo (below).
D. Using SCC-supplied nuts & bolts, lightly tighten
each of
the bolts in a cross-wise pattern. Work your way around
the pattern, tightening more firmly at each pass. Do not
completely tighten one bolt and then start on next!
E. As cases are being bolted together, check that case is still
level. Adjust levelers (or shim) accordingly. Repeat this
process for each adjoining case.
2. Wiring Cover and Rear Door Replacement
Reattach wiring cover and replace rear doors when done.
