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 and fluorescent lamps reflect specific size, shape and design.
Any replacements must meet factory specifications, resist breakage and
reflect similar appearance as lamps from factory.
CAUTION
PRECAUTIONS
• This sheet contains important precautions to prevent
damage to unit or merchandise. Please read carefully!
• See previous page for specifics on OVERVIEW,
TYPE, COMPLIANCE and WARNINGS.
WIRING DIAGRAM
• Each case has its own wiring diagram folded and in its
own packet.
• Location: Diagram may be 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,

OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PAGE 2 of 2
CAUTION! CHECK CONDENSATE PAN POSITION & PLUG
Water on flooring can cause extensive damage!
Before powering up unit, check and confirm the following:
• 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 TWO PLUGS connected.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
• Performance issues caused by adverse conditions are NOT warranted.
• To prevent damage to end panels due to condensation, apply industrial grade
silicone sealant and tightly join to opposite end panels. When not adjoining
cases, keep end panels at least 6” away from walls/structures. Rear panels
must also be kept at least 6” from walls and structures.
• Case must not be exposed to direct sunlight or any heat source.
• To maintain proper case temperature, keep case at least 15-feet from exterior
doors, overhead HVAC vents or any air curtain disruption.
CAUTION
CAUTION! DO NOT RELY ON THERMOMETERS OR
THERMOSTATS FOR PRODUCT (FOOD) TEMPERATURES.
• Thermometers & thermostats reflect air temperatures ONLY.

INSTALLATION: CASE REMOVAL (VIA LEVELERS & CASTERS)
1. Remove Case From Skid (Levelers)
• Remove shipping brace that may be securing
case to skid.
• Support case to prevent tipping.
• Caution! Levelers can be damaged if case hits
floor with heavy force!
• Carefully slide unit to rear of skid and tip backward
off skid.
• Illustration may not reflect every feature or option
of your particular case.
• Case can be repositioned with pallet truck when
front lower panel is removed. Blocking may be
necessary to obtain adequate height.

2. Remove Case From Skid (Casters)
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 all the way up, place ramp
up against skid (to allow case to smoothly roll off
from skid).
• Maintain support of case at all times or center of
gravity may cause case to fall.
• Roll unit to rear of skid. Roll down ramp and off skid.

6
INSTALLATION, CONTINUED: POSITIONING & ALIGNING CASE / ADJUSTING LEVELERS
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 the 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.
• You may need to remove front and/or rear toe-kick to access levelers.
• Use adjustable wrench to adjust leveler.
• Depending upon case weight it may be necessary to use a pry bar to accomplish this task.
• Do not use pry bar on toe-kick as it may buckle.
• Do not use pry bar on end panel as it may chip.
• Use pry bar ONLY on base frame to avoid damaging case.
• See illustrations below.

illustration ”B” on this sheet).
C. Check that the lock properly rotates its locking
mechanism into support angle slot (at upper
area).
> When removing security cover from case, store in
safe location away from foot traffic.
> Manufacturing note: if your case DOES NOT HAVE
the hardware shown on this sheet for proper
placement of security cover, contact Structural
Concepts Corporation Technical Service. Toll-free
number is listed on the last page of this document.

INSTALLATION, CONTINUED: ADJOINMENT INSTRUCTIONS
7. Overview / Silicone and Buty 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 Urethane 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 urethane has ALREADY been applied.
• Also place a thick bead of urathane around drain.
8. 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.
