CAUTION
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.
CAUTION! CHECK CONDENSATE PAN, ITS POSITION & PLUG!
Water on flooring can cause extensive damage!
• Before powering up case, check that condensate pan is positioned
directly under case’s condensate drain.
• Before powering up case, check that condensate pan’s electrical plug is
SECURELY connected to condensate system’s receptacle.
• If wicking material is used in condensate pan, check that it is secure.

INSTALLATION: REMOVAL FROM SKID, REMOVING VERTICAL LOWER FRONT PANELS
1. Remove From Skid (Rails or Levelers)
• Remove shipping brace that may be securing case to skid.
• Support case to prevent tipping.
• Caution! Frame Support Rails (or 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.
Note: Case can be repositioned with pallet truck
when front lower panel is removed. Blocking may
be necessary to obtain adequate height.

INSTALLATION, CONT’D: BOLTING AND SEALING UNITS TOGETHER
3. Bolting and Sealing Units Together
Follow these steps to assure a secure, level lineup.
A. Begin lineup leveling from highest point of floor.
B. After ‘first’ case is level, apply industrial grade
urethane on non-visible areas (at case end). Use
industrial grade silicone sealant on visible areas
(at case end). See caulk/silicone illustrations at
lower-left.
C. Form Two (2) Urethane/Sealant Lines: (Sanitation
and Refrigeration). See illustration below for
outline of urethane/sealant lines.
D. Line up ‘second’ case bolt-hole to bolt-hole to ‘first’
case.
E. Using SCC-supplied bolts (and/or screws) found in
installation packet, insert bolts in bolt hole locations
(shown below). You may need to remove decking to
access lower bolt holes.
F. Caution! Front of cases MUST be flush with each
other! After leveling, cases are to be same height.
G. Using SCC-supplied nuts & bolts, lightly tighten
each of the 5 to 8 bolts in a cross-wise pattern.
Work your way around the pattern, tightening more
firmly at each pass. Do not firmly tighten one bolt
and then start on the next!
H. After the cases are bolted together, level the
‘second’ case. Repeat this process for each case
to be adjoined.
I. After all lined-up cases are level, seal all seams
with industrial grade silicone sealant.
Approximate hole locations pointed at with
arrows ( ) for bolting units together.

7. Front Glass Alignment & Adjustment via Rails / Levelers (For Curved / Flat Front Glass)
• Proper alignment of the front glass is important to create and maintain a seal inside the case.
• Improper alignment can cause air leaks compromising the environment inside the case and create condensation.
• Follow the five steps listed below to assure proper front glass alignment.
B. Front-to-Back Leveling:
• Place a level on top of case,
perpendicular to the front glass.
• Raise or lower either side of case by
shimming under the rails or adjusting
levelers (following steps 3 & 4 below).
• Double-check the side-to-side level.
A. Side-to-Side Leveling: Place a level on top of display case (parallel
to front glass). Level the case by inserting shims under the rails (or,
for levelers, rotating either clockwise or counter-clockwise).
Follow steps 3 and 4 below for specifics.
E. Verification:
• After inserting shims (or adjusting levelers), open and shut the front glass.
• Verify (again) that front glass is properly aligned at left-hand and right-hand side of the case.
• If not, repeat the shimming procedure (or leveler adjustment) until the front glass is properly
aligned along both sides of the case.

• Remote Units: Case will power-up when properly
field wired.
• After case is powered up, open rear doors (or
front glass (see illustration below).
• If at case front, lift decking to check that coil fans
are running.
• Coil fans (and in self-contained units, compressor
motor) should turn on.
B. Lights
• Turn lights on.
> Remote Units: Switch is likely at rear plenum or
upright (as shown below).
• All lights should come on at the same time.
• Lighting is wired in series so all lights must be
plugged in or receptacles capped for case
lights to be on. See illustration at right.
• LED Lights may have single or dual rows
(depending upon model).
• Note: If lights do not come on, check that plug is
properly inserted into socket.

MAINTENANCE: LED LIGHT REMOVAL/REPLACEMENT, PLUG/CORD CONNECTION
1. LED Style Light Fixtures
Removal of Faulty LED Lights:
• Contact Structural Concepts’ Technical Service
Department for replacement LED lights.
• Turn off LED light switch.
• To remove faulty LED light, follow these steps:
A. Disconnect plug from LED light.
B. Using both hands, grasp LED light assembly
(with its magnetic mounting clips). Pull
downward and off its shelf (or header).
C. Remove magnetic mounting clips from LED light
by pressing against flange part of clip with
thumb.
>> Note: Mounting clips MAY be riveted to shelf or
header. In such instances, simply remove LED light from
mounting clips by pressing against flange part of clips
with thumb.
Replacement of LED lights:
• Attach magnetic mounting clips onto LED light.
• Adjust magnetic mounting clips so they are equally
spaced on LED light.
• Reattach LED light assembly to its shelf/header.
• Position properly in shelf/header.
>> Note: If mounting clips are riveted to shelf (or head-
er), attach by placing LED in base of clip and then
snapping into clip at FLANGE SIDE.
• Press plug’s barrel-shaped insert deep into LED
light.
• Important: If plug is not inserted ALL THE WAY IN
the LED light’s orifice, the light may not energize.

MAINTENANCE, CONT’D: REAR SLIDING DOORS / THERMOMETER
3. Rear Sliding Doors
Note: Doors are not interchangeable. There is an
inner and outer door.
• The outer door is the right hand door (from the
service side or rear of case).
• It is identified by a stop located at the lower right
hand corner to the inside of the case.
• To remove, move doors toward the center of the
case.
• Outer door must be removed first and replaced
last.
• Individually lift each door up toward the top of the
case; pivot the bottom of the door out.
• Carefully set rear sliding doors down to prevent
them from falling.
• Replace rear sliding doors in reverse order they
were removed.
4. Thermometer (Placement and Function)
• Thermometers are found at varying locations.

MAINTENANCE, CONT’D: HINGED FRONT DOORS WITH LOCKING MECHANISM
5. Hinged Front Doors With Locking Mechanism (Model GHSV852RLB Shown)
• Caution! Do not open doors BEYOND their hinges stopping points. Doing so can weaken or break door
hinges or glass.
• These models’ locking mechanisms prevent easy entry from customers and allows merchandiser to be
accessed from front by store personnel only.
• To allow either set of doors to be opened at side hinges, lift upward on locking mechanism, grasp
underside of glass doors and slowly open outward.
• Doors will open at side hinges. After access, doors may be slowly closed with light pressure.
• Caution! After doors have fully closed, you must press downward on locking mechanism to prevent
doors from being opened by customers.
