OVERVIEW, CONT’D
CAUTION
• This sheet contains cautionary notes and information
on shelving load limits, lamp replacement, GFCI
(Ground Fault Circuit Interrupters) breaker use,
CAUTION! GFCI BREAKER USE REQUIREMENT
If N.E.C. (National Electric Code) or local code requires GFCI (Ground Fault
Circuit Interrupter), use a GFCI breaker in lieu of a GFCI receptacle.
CAUTION! LAMP REPLACEMENT GUIDELINES
LED lamps reflect specific size, shape and design.
Any replacements must meet factory specifications, resist breakage
and reflect similar appearance as lamps from factory.
CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord(s) and/or plug(s) becomes damaged,
replace only with cord(s) and/or plug(s) of same type.
CAUTION! CHECK CONDENSATE PAN, POSITION & CONNECTIONS!
Water on flooring can cause extensive damage!
• Before powering up case, check that condensate pan is positioned directly
under case’s condensate drain.
• Also, check that there are NO LOOSE CONNECTIONS, including overflow
condensate pan and its power cord plug (if part of the condensate package).
CAUTION! DO NOT RELY ON THERMOMETERS OR
THERMOSTATS FOR PRODUCT (FOOD) TEMPERATURES
• Thermometers & thermostats reflect air temperatures ONLY.
• For ACTUAL product (food) temperatures, use a calibrated food
probe thermometers ONLY.
• For accurate readings, DO NOT use infrared food thermometers.
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.
• Adjoined cases MUST BE connected to each other so that vending controls
system can communicate with adjoined case.

OVERVIEW, CONT’D
ENGLISH TO FRENCH LANGUAGE TRANSLATION
Structural Concepts markets its products in countries with both English and French as their official languages.
As with any translation, their can be issues to contend with. Here are a few:
• There can be abbreviations. When translating abbreviated words to a different language, readers of translated text
can be confused as to what meaning the abbreviated words were to convey. Abbreviations have been removed from
the English text so that the translation into French is more understandable.
• There can be language structure differences (which can vary widely between languages). For example, in the
English language, the adjective is placed before the noun; but in French, the adjective comes after the noun.
• There can be missing terms (which can be difficult to translate if there is no equivalent term in the target language).
• There can be compound words (usually a combination of two or three nouns and adjectives) that can be difficult to
maintain accuracy.
• There can be verbs made up of two words (usually a combination of a verb and a proposition). Examples are break
down, fill up, etc.). These can sometimes be translated inaccurately.
• There can word with several meanings (depending on how it is used in a sentence).
• There can be specialized knowledge which may be required to translate technical texts.
Structural Concepts utilizes the latest language translation software available on the market today to translate its
English written documents into French. It employs a well-maintained revision system to constantly update its
documentation (whether in English or French) whenever warranted.
If there be a sentence, phrase or term that can be more accurately translated, please contact Structural Concepts at the

1. Disconnect Case From Skid
• Remove front and rear panels.
• Also, remove shipping brackets that
secure casters to skid
• Important! Case is shipped with levelers
in the DOWN position (for stability). To
prevent damage to the case, all levelers
must be raised ALL THE WAY UP before
moving unit off skid and into position.
• After levelers are raised, place ramp up
against skid (to allow case to smoothly
roll off from skid).
2. Roll Case Off Skid via Ramp
• Maintain support of case at all times or
center of gravity may cause case to fall.
• Roll unit to rear of skid.
• Check that ramp is secure and possibly even
attached to skid with screws.
• Carefully roll down ramp and off skid.
3. Position & Align Alongside Other
Cases
• Before adjusting levelers, make certain that the
case is in proper position and, if required,
aligned with adjoining case(s).
• This may require repositioning of the case you
are installing or the already positioned cases.
4. Adjusting Levelers
• Important! After case is in proper position,
levelers must then be LOWERED to floor.
• Adjust levelers so the case is level and plumb.
Depending upon case weight it may be
necessary to use an indexing flat pry
bar (or similar pry bar) to do so.
• Use adjustable wrench to adjust leveler.
• Do not use indexing flat pry bar on
end panel as it may chip.
• Use indexing flat pry bar ONLY on base frame to
avoid damaging case.
• See illustrations at right.
• After case if level and plumb, you may replace
front and rear panels.

• Front and rear panel can be removed/replaced
by simply grasping top ‘lip’ and pulling
outward, freeing it from magnets.
• See illustration below.
2. Check Condenser Package Connections
Before Powering Up Case!
• Caution! Connections can come loose
during shipment; this can allow water to
overflow onto floor, causing damage!
• When case in is proper location, remove front
and rear panels to check for loose
connections, including overflow condensate
pan and its power cord plug (if part of the
condensate package).
• See TROUBLESHOOTING section in operating
manual for various troubleshooting issues.
3. Turning On Power To Case
• Plug in power cord.
• Turn on main power switch (at lower left).
• Return front and rear panels to case.
• Check that programmable controller is energized.
• Open door: check that LED light in upper plenum
is energized and that evaporator fans are rotating.

See INSTALLATION section in this manual for instructions on properly aligning case
(alongside other cases) and adjusting levelers.
Water Is On
The Floor
Caution! Water on flooring can cause much damage! Until cause is determined (and
repaired), follow these procedures:
• Use wet-dry vacuum (or mop & bucket) to remove standing water.
• Use ‘catch pans’ for water to drain into. Swap out regularly until case has completely
drained.
Check that the drain trap is free from debris.
Check that the drain hose/pipe is correctly positioned over condensate pan (or floor drain,
for remote units).
Check store conditions. To prevent condensation in NSF/ANSIType II environments,
conditions are to be 55% maximum humidity / 80° Fahrenheit (27° Celsius) maximum
temperature.
Check that condensate pan components have no loose connections.
Check that overflow condensate pan (if any) has its power cord plug properly plugged into
electrical box.
Check that overflow condensate pan (if any) is not malfunctioning. Its electric rod heater
should be heating up when case is energized.
Caution! Disruption of power can cause water to overflow pan and seep onto flooring
causing damage! Check that power to case is constant. Until power is restored, follow
these procedures:
• Use wet-dry vacuum (or mop & bucket) to remove standing water.
• Use ‘catch pans’ for water to drainage. Swap out regularly until drainage of case is
complete (or until power is restored).
• When power to case is restored, condensate pan should function properly and water
will no longer overflow onto flooring.
