OVERVIEW
 These Structural Concepts merchandisers are
designed to merchandise pre-chilled packaged
products at 41 °F [5 °C] or less product temperatures.
 This self-contained refrigerated unit is a barista serve
unpackaged food and customer self serve packaged
food and drink case.
 Cases should be installed and operated according to
this operating manual’s instructions to ensure proper
performance.
 Improper use will void warranty.
NSF® 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 NSF® Type 1 Conditions (most cases): ambient
conditions are to be at 55% maximum humidity and
maximum temperatures of 75 °F [24 °C].
 For NSF® 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 NSF® 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.
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 sheet contains important warnings to prevent
injury or death.
 Please read carefully!

OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PG 2 of 2
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! 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
(ovens, fryers, etc.).
 Tile floors, low ceilings or small rooms increase noise level. Whisper
Cool compressor blankets or remote units resolve noise level issues.
 Keep at least 8-inch clearance above unit for air discharge
(self-contained units only).
CAUTION
CAUTION! LAMP REPLACEMENT GUIDELINES
Fluorescent lamps have been treated to resist breakage and
must be replaced with similarly treated lamps.
CAUTION
PRECAUTIONS
 This sheet contains important precautions to prevent
damage to unit or merchandise.
 Please read carefully!
 See previous page for specifics on OVERVIEW, NSF
TYPE, COMPLIANCE and WARNINGS.
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! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
CAUTION! CHECK CONDENSATE PAN POSITION & PLUG
Water on flooring can cause extensive damage!
Before powering up unit, check and confirm that:
 Condensate pan is DIRECTLY UNDER condensate drain.
 Condensate pan plug is securely plugged into receptacle.
 Overflow pan has plug connected to its box. Units with optional
Clean Sweep™ MUST HAVE 2 plugs connected.

REFRIGERATION ASSEMBLY REMOVAL, CASE REMOVAL AND LEVELER ADJUSTMENT
1. Removing Refrigeration Assembly
 Note: Retain screws that are removed from the
CASE shipping brackets (Screws will be used as
Toe-Kick fasteners).
 Remove front panel.
 Lift front panel upward from the lower edge,
approximately one half inch to detach from the
retainer hooks.
 Remove all shipping brackets from units base and
compressor.
 Reuse shipping bracket screws for Toe-Kick
mounting.
 Note: Make sure all hoses and power cords are
disconnected before completely removing
compressor from unit.
 The compressor base is on casters. Roll the
assembly out half way straight out from the front
of the case.
 Carefully lower assembly to floor.
 After compressor unit is removed, roll out of the
way while locating and setting case.
2. Removing Case from Skid
 Slide case halfway off back of skid.
 Lower case onto back rear levelers.
 Tilt case back enough to free skid.
 Slide skid out from front of case, lower case to
floor.
3. Leveling Case
 Levelers may need to be adjusted for proper height
clearance to fully insert unit.
 Tools needed: level, pry bar, and adjustable
wrench.
 Using a level, find the highest point on the case.
 Level the case to that highest point by turning the
levelers up or down to the desired level position.

START-UP AND OPERATION
1. Merchandiser Start-Up
 Remove rear toe-kick (by removing four screws,
two at each end).
 Turn main power on. Switch (220V) is up and
under rear raceway on right side of case.
 The Controller display will illuminate.
 Coil fans should turn on. From inside case, check
for discharge air from front baffle to confirm that
fans are functioning properly.
 When the case is in a start up mode or has been
idle for a long period of time, the unit will require
75 minutes in order to pull-down temperature.
 Self-Contained refrigerated cases must maintain
front airflow clearance of approximately twelve
inches and rear airflow clearance of approximately
six inches.
 Obstruction / restriction of air voids warranty.
 The interior case temperature is to reach 2 °C /
35 °F to 5 °C / 41 °F.
 Note: Case temperature is set at the factory, as
determined by the case size. Temperature is
controlled by a thermostat.
 If a temperature setting change is required, refer
to the Temperature Controller section of this
operating manual.
 Note: According to product displayed, Set point
should be -6 °C / 22 °F to -3 °C / 26° F. This will
maintain the product temperature range. Settings
lower than this can cause product to freeze.
2. Set Point & Differential Adjustment Guideline
 Caution! The Differential MUST be adjusted
either up or down in tandem with the Set point.
 For example, if the Set point is raised from 22 °F
to 26 °F (a 4 °F increase), the Differential must
also be raised by 4 °F from (11 °F to 15 °F).
 Keeping the Set point and Differential
temperatures ‘in tandem’ will maintain product
temperature and prevent excessive compressor
cycles.

3. Fluorescent Light Guidelines
 Turn lights on. All of the lights should come on at the
same time. First time lighting may require a short warm
up period for the bulbs. Slightly dim or a flickering of
new bulbs is normal. If lights do not turn on, check that
all of the light plugs are in.
Removal of lamps:
 Grasp lamp firmly and carefully pull downward and out
from socket.
 See photos at mid-right.
Installation of lamp:
 Align pins with slot.
 Insert pins into socket and push upward into place.
