OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - 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 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].
For Type 2 Conditions: ambient conditions are to be
at 60% maximum humidity and maximum
temperatures of 80 °F [27 °C].
This equipment MUST be installed in compliance with
all applicable NEC, federal, state and local
electrical and plumbing codes.
If unsure if unit is designed for 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 page contains important warnings to prevent injury
or death.
Please read carefully!

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! LAMP REPLACEMENT GUIDELINES
LED lamps reflect specific size, shape and overall design.
CAUTION
Any replacements must meet factory specifications.
Fluorescent lamps have been treated to resist breakage and
must be replaced with similarly treated lamps.
CAUTION! GFCI BREAKER USE RECOMMENDATION
If N.E.C. (National Electric Code) or your local code
requires GFCI (Ground Fault Circuit Interrupter) protection,
the use of a GFCI breaker
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.
is strongly recommended.
CAUTION
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT warranty.
Unit must be kept at least 15-feet from exterior doors, overhead HVAC
vents or any air curtain disruption to maintain proper temperatures.
So not exposed to direct sunlight or heat sources (ovens, fryers, etc.).
Tile floors/low ceilings/small rooms 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!
Before powering up unit, check and confirm that:
Condensate pan is DIRECTLY UNDER condensate drain.
Condensate pan plug is securely plugged into receptacle.
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.

CUSTOMER CABINET PROVISIONS
Customer Cabinet Provisions
Customer provided cabinet must adhere to the minimum requirements in ANSI/UL Std. 471 and ANSI/
NSF Std. 7.
Among the factors that are to be taken into consideration when judging the acceptability of a cabinet or
similar enclosure are mechanical strength, resistance to impact, moisture-absorptive properties, flame
resistance, resistance to distortion at temperatures to which the material may be subjected under
conditions of use, and resistance to corrosion.
Customer provided cabinet or similar enclosure shall have the strength and rigidity necessary to resist
conditions of intended use without increasing the risk of fire or injury to persons due to total or partial
collapse. Cabinet or similar enclosure must be strong enough to hold weight of cabinet and intended
product load. Dry weight (no product in case) exceeds 500 pounds.
A nonmetallic cabinet or similar enclosure (or part of an enclosure) shall have a flame spread index of not
more than 200 when tested in accordance with the Standard for Tests for Surface Burning
Characteristics of Building Materials, UL 723.
The cabinet or similar enclosure shall be constructed and assembled to reduce the risk of fire due to the
emission of molten metal, burning insulation, flaming particles, or the like, through openings onto
flammable material, including the surface over which the refrigeration is mounted.
A sheet metal cabinet or similar enclosure is to be judged for acceptability with respect to its
size, shape, metal thickness. Sheet metal such as galvanized or stainless shall be 0.30 inch
(22 gage) or greater.
Steel enclosures shall be protected against corrosion by metallic or nonmetallic coatings, such
as plating or painting.
The refrigeration access panel/door shall be arranged so that main power switch, refrigeration controller
and refrigeration package are accessible without removing parts other than access panel/door.
A hinged or pivoted panel shall be positioned or arranged so that when it is in an open position
falling or swinging due to gravity or vibration will not cause injury to persons.
For electrical protection when installed in its intended manner, louvers and other openings in the
enclosure shall be constructed and located to reduce the risk of unintentional contact with moving, live or
hot parts such as fan blades and condensate trays. The minor dimension of such openings shall not
exceed 3 inches—See Table 6.1 for Clearance from Openings. Tools are required to remove covers,
panels or grilles unless interlock is provided.
Ventilation openings/louvers shall be free of sharp edges and burrs and have spaces large enough to
allow for easy cleaning. Louvers that may be subject to splashes, spills, and overhead drips shall be of a
drip-deflecting design.

CLEARANCE FROM OPENINGS / SERVICE TOP CUTOUT DIMENSIONS / CLEARANCE DIMENSIONS
1. Clearance From Openings [Standard]
2. Service Top Cutout Dimensions
Note: See Manual Cover for Service Top Cutout
Dimensions.
3. Clearance Dimensions
The Refrigerated section must maintain airflow
clearance. Dimensions are as follow.
1. 4" Minimum Spacing from bottom of refrigeration
frame to bottom of cabinet or floor required for adequate
air flow.
2. 9 1/2" Countertop / Fascia enclosure space on cabinets
or counter to allow for pullout system slide-out.
3. 15" Minimum opening in back of cabinet or counter
(to pull out refrigeration system).
4. Back of counter / cabinet ventilation must be at specific
space to allow for proper air intake and exhaust. See
illustration at right.
5. Front of counter ventilation must be at least 2” to allow
proper air intake and exhaust. See illustration at right.
6. Obstruction or restriction of air can void warranty.
Note: See Venting Instructions sections (next page)
for more specific Air Intake and Air Exhaust
clearance dimensions.

NOTES:
1. THE IDEAL CONDITION FOR REAR OF CABINET IS TO HAVE COMPLETE OPEN SPACE (WITH NO DOORS
OR BLOCKING OF AIRFLOW WHATSOEVER).

PROVIDED.
LOUVERS (or SCREENING) MUST BE 2” OR CLOSER TO EACH OTHER VERTICALLY.
LOUVER (or SCREENING) MUST EXTEND AT LEAST 4” BEYOND EACH END OF REFRIGERATION UNIT.
THIS SHEET REFLECTS THE MINUMUM REQUIRED VENTILATION. ADDITIONAL VENTILATION IS
RECOMMENDED AND WILL HELP MAINTAIN ACCEPTABLE MERCHANDISING TEMPERATURES.

4. UNITS WITH REAR
LEAST A 3-FOOT SPACE
5. UNITS WITH FRONT
WALL, IF DESIRED.
REFRIGERATION PACKAGE SLIDE-OUT (AS SHOWN BELOW) MUST MAINTAIN AT
