Design Guide
Tips on integrating your 32”D
Structural Concepts under
counter display case into a
counter.
The shape of the under counter display
cases makes them ideal for integrating
into counters so that all customers see is
fresh food. These models are modular,
and are designed to slide into/between
counters. They include a self-contained
refrigeration system in the base and a 6’
power cord for simple plug & play
installation.
Planning the space in the counter to
accommodate the modular display
takes careful consideration of key
dimensions and ventilation requirements. To ensure a surprise free
installation, the items in this guide
should be addressed early in the design
process.
Structural Concepts under counter models are available in 32”
& 24” depths. This guide is for the 32”D models.
Models are available for under counter, counter height & freestanding applications. The under counter models (–UC
suffix) are the ones that should be specified for building into counters.

Refrigerated under counter
models are designed to

when properly planned into
the space. To avoid gaps
like shown here, refer to
the critical dimensions
noted in this Design Guide.

VENTING
The design of the counter must allow proper air intake and discharge for the
refrigeration system. The refrigeration system breathes in from the rear of the
display. This area must remain completely open for proper air intake, as well as to
provide access to the condensing unit for maintenance and service. The
condensing unit slides out the rear of the display.
Compressor air intake
Counter Opening
Keep area behind the display open for
ventilation & condensing unit access.
Warm air from the condensing unit is discharged out the
front of the display at the toe kick. The toe kick in the
front of the counter should match the toe kick on the
equipment (Option 1). The toe kick is recessed 3 1/4”
from the front panel and left open at the top to allow
discharge of hot air. If this same design is not followed in
the counter toe kick, vents are required to provide the
square inch openings noted below. Also, if vents are part
of the counter toe kick, the toe kick on the equipment
must be removed (Option 2).

CRITICAL
COUNTER
DIMENSIONS
The top board of the equipment is designed to be under the counter surface. The
display equipment is supplied with recessed casters and a leveling leg next to it. The
32 3/4” AFF dimension provided is to the bottom of the caster. The leveling leg can
drop down up to an additional 1” below the caster. Any adjustment to the leveling
leg needs to be considered relative to the AFF dimension provided. The dimension
to the top of the end panels is the same as the top board on the equipment.

COUNTERTOP
SURFACE
Once the modular equipment is pushed into the opening in the counter, the
counter surface can be positioned over the entire counter and display. In most
installations, the counter surface extends over the end panels and the entire top
board of the display.
NOTE: The overall depth of the counter should be determined based on the 32
3/8” depth of the equipment and the depth of the front wall.

A 6’ power cord is supplied and exits the display through the lower rear panel. See
dimensions below. Refer to model specification sheet for electrical requirements
and plug configuration.
Important Items to Consider
 All food display cases are designed to operate in a controlled environment of 75°F and 55% relative
humidity. Structural Concepts under counter models are designed to operate in higher ambient
environments of 80° F. and 60% relative humidity.
 Keep in mind that energy management & smart thermostats can alter ambient conditions over a 24
hour period. Equipment designed to work in higher ambient conditions (noted above) is well
equipped to perform in these environments. Even so, a pull down night curtain is recommended for
non-operating hours.
 Where GFI is required by code, the display equipment must connect to a GFI breaker, not a GFI wall
receptacle. The cycling of the compressor will trip a GFI wall receptacle.
 Avoid placing food display cases in locations near exterior
doors, HVAC ceiling vents or where the display will be exposed to direct sunlight. These areas can cause issues with
temperature performance. See illustration below as a typical
example of how far to stay away from these areas.

model specification sheets on the website. To build these types of models into counters, refer
to the models with the -UC suffix.
