OVERVIEW / CONDITIONS / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 1 of 2
OVERVIEW
These Structural Concepts merchandisers are
designed to merchandise packaged products at
41 °F (5 °C) or less product temperatures.
Cases should be installed and operated according to
this operating manual’s instructions to ensure proper
performance.
Improper use will void warranty.
TYPE I vs. TYPE II ENVIRONMENTAL CONDITIONS
This unit is designed for the display of products in ambient
store conditions where temperature and humidity are
maintained within a specific range.
Type I display refrigerators are intended for use in an
area where environmental conditions are controlled and
maintained so that the ambient temperature does not
exceed 75 °F (24 °C) and 55% maximum humidity.
Type II display refrigerators are intended for use in an
area where environmental conditions are controlled and
maintained so that the ambient temperature does not
exceed 80 °F (27 °C) and 55% maximum humidity.
If unsure if your unit is Type I or II, see tag next to
serial label. See SERIAL LABEL LOCATION &
INFORMATION LISTED / TECH INFO & SERVICE
section in this manual for sample serial labels.

OVERVIEW / CONDITIONS / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 2 of 2
PRECAUTIONS
This sheet contains 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! LAMP REPLACEMENT GUIDELINES
Fluorescent lamps have been treated to resist breakage
CAUTION
and must be replaced with similarly treated lamps.
If LED lamps are used, they must 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! 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! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT warranted.
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.
Self-Contained Units: Keep 4” min. air intake / 4” min. air discharge clearance.
CAUTION! CHECK EVAPORATOR PAN POSITIONS AND PLUG
Water on flooring can cause extensive damage!
Before powering up unit, check the following:
Hot gas evap. pan MUST BE positioned directly under condensate drain.
Overflow evap. pan plug MUST BE securely plugged into receptacle.
CAUTION!
DO NOT RELY ON THERMOMETERS OR THERMOSTATS
FOR ACTUAL PRODUCT (FOOD) TEMPERATURES.
Thermometers and thermostats reflect air temperatures ONLY.
For ACTUAL food temperatures, use a calibrated food thermometer.

INSTALLATION, CONTINUED: SYNCHRONOUS DEFROST CONNEC TION (OPTIONAL)
4. Synchronous Defrost Connection (Optional)
Adjoined cases MUST HAVE its synchronous defrost plugs connected.
See wiring diagram accompanying case.
Attention!
Adjoined cases have
synchronous defrosts.
Synchronous Defrost
Plugs Must Be Connected
At Rear of Electrical Box
During Case Adjoinment.
See Your Case’s Wiring
Diagram For Instructions.

INSTALLATION, CONTINUED: SILICONE & BUTYL APPLICATION / BOLTING ADJOINED UNITS
5. Overview / Silicone and Butyl Application
Sealant Overview:
Warranty is void if improper sealant is used.
Sealing tub prevents air from escaping through seams
between cases (causing condensation problems and
reducing refrigeration efficiency).
Sealing also prevents water from seeping between
cases to the floor.
Silicone and Butyl Application:
Form (1) INNER sanitation bead AND (1) refrigeration
bead BEFORE case is adjoined (as shown).
Then, AFTER case is adjoined (and bolted), form (1)
OUTER sanitation bead (as shown) into any cavities or
gaps that may remain along outer adjoinment areas
where butyl has ALREADY been applied.
Also place a thick bead of caulk around drain.
6. Bolting Adjoined Units
Bolt holes are at various locations (depending upon
model). Model illustrated MAY NOT exactly reflect your
particular unit but will likely be similar in layout.
Use appropriately sized nuts and bolts for each hole.
#1 hole is accessible at honeycomb (slight adjustment
or removal of honeycomb air diffuser may be
necessary for attachment of bolt).
#2 hole is accessible near rear plenum.
#3, 4 & 9 holes are accessible after removing decking.
#5-6 holes are accessible after removing front panel.
#7-8 holes are accessible after removing rear panel.
>> Be sure to reattach components to case after the
adjoinment process is complete.

MAIN POWER SWITCH - START-UP / TEMPERATURE CONTROLLER / LIGHT SWITCH
1. Main Power Switch - Start-Up
Remove the front grille simply by lifting up and
off (no screw removal required).
Turn on the main power switch. Main power
switch is on the left hand side of unit (accessible
after front grille has been removed). Evaporator
coil fans, and compressor motor (for units with
self contained refrigeration) will energize.
From the front of the case, raise the deck pans
and check to see that the coil fans are all
functioning properly. Caution! Rotating fan
blades are sharp. Do not place fingers near
rotating blades!
Replace front grille in reverse order it was
removed.
2. Temperature Controller
The case temperature is set at the factory,
(supply air is set for a case temp at 5 °C / 41 °F
as as determined by the case size.
The temperature is controlled by a thermostat.
See illustration at right for thermostat location.
If a temperature setting change is required,
refer to the CAREL® TEMPERATURE
CONTROLLER INFORMATION section of this
operating manual.
3. Light Switch At Header, Upper-Left
Whether fluorescent or LED lights are used on
case, switch is at header, upper-left (as shown
immediately below).
Turn on light switch.
All lights should come on at the same time.
Fluorescent bulbs may require a short warm-up
period; initially, new fluorescent bulbs may be
slightly dim or flicker.
Whether fluorescent or LED, if lights do not turn
on, check plug connections
