INSTALLATION: REMOVAL FROM SKID, REMOVING LOWER FRONT PANELS
1. Remove Case From Skid
• Remove shipping brace that may be
securing case to skid.
• Support case to prevent tipping.
• Caution! Rails can be damaged if case hits
floor with heavy force!
Case can be repositioned with pallet truck when
front lower panel is removed. Blocking may be
necessary to obtain adequate height.
Slide Skid Out
• Carefully slide unit to
rear of skid and tip
backward off skid.
• Illustration may not
reflect every feature
or option of your
particular case.
2. Remove Case From Skid (Casters)
Remove shipping brackets that may be securing
casters to skid
• Place ramp up against skid (to allow case to
smoothly slide off from skid).
• Maintain support of case at all times or center
of gravity may cause case to fall.
• Unlock Casters. Roll unit to rear of skid.

INSTALLATION, CONT’D: CASE ADJOINMENT INSTRUCTIONS
4. Case Adjoinment Instructions
>> Warranty is void if improper sealant/urethane is used.
>> Lay generous beads of sealant/urethane as specified.
A. Prior To Adjoinment - Apply Industrial Grade
Urethane Adhesive at Center of Uprights
• Lay a generous bead of industrial grade urethane
adhesive at center of uprights (in non-visible areas).
• This urethane adhesive prevents refrigerated air from
escaping between cases (causing condensation and
reducing refrigeration efficiency) as well as preventing
ants or other insects from entering case.
• See industrial grade urethane adhesive illustration
below-left.
B. Adjoining Cases - Using Bolts and Nuts
• Use appropriately sized nuts and bolts for each hole.
#1 - Hole is accessible through rear sliding door (if you
are able to avoid gas cylinder, attach bolt); otherwise
start at #2 in bolt/nut attachment process.
#2 - Holes are accessible through rear sliding door.
#3 - Holes are accessible at underside of decking.
Decking must be removed to attach bolts/nuts.
#4 - Holes are accessible at base frame (through front of
case after front toe-kick has been removed).
• Tighten nuts securely (but do not over-tighten).
• See illustration below.
C. After Adjoinment - Apply Food Grade Silicone Sealant
To Inner And Outer Seams
• After all nuts/bolts are securely attached to case, apply a
generous bead of food grade silicone sealant at both inner
and outer seams.
• When properly applied, this food grade silicone sealant will
prevent water from seeping between cases (into the case or
to the floor) as well as crumbs or other residue from
entering between case seams.
• See silicone sealant illustration
below-left.
>> You must reattach toe-kick and
decking after case adjoinment
process is complete.

INSTALLATION, CONT’D: POSITIONING & ALIGNING CASE / FRAME SUPPORT RAIL SHIMMING
5. Position & Align Case Alongside Other
Cases
• Before adjusting levelers (or shimming frame
support rails), make certain that the case is in
proper position and, if required, aligned with
adjoining case.
• This may require the repositioning of the case
you are installing or the already positioned case.
• Though case below shows both end panels,
case adjoinments routinely consist of end panel
removal for case-to-case placement.
Frame Support
Rails
6. Frame Support Rails Must Be Shimmed
• Illustration below shows case with frame
support rails.
• Shims will be provided with all cases that have
frame support rails.
• Use shims to level case.
• Note: After case is in position, it must be
sealed to floor to prevent entry or leakage
of liquid or moisture.
Note: Illustration shown may not
exactly reflect every feature or
option of your particular unit.

INSTALLATION, CONT’D: FRONT GLASS ALIGNMENT & ADJUSTMENT (VIA RAIL SYSTEM)

Case with Curved
Front Glass
7. Front Glass Alignment & Adjustment via Rail System (For Curved and 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.
• Illustrations shown may not exactly reflect every feature or option of your particular case.
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
(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). Raise or lower either side of case by inserting shims
under the rails to level the case (following steps 3 and 4 below).
E. Verification:
• After inserting shims, open and shut the front glass.
• Verify (again) that the front glass is properly aligned at both left-hand and right-hand side of
the case.
• If not, repeat the shimming procedure until the front glass is properly aligned along both sides
of the case.

START-UP AND OPERATION
Merchandiser Start-Up
• Unit will energize when properly field wired.
• Evaporator coil fans will automatically turn on.
From the front of the case, lift glass and remove
the decking; check to see that the coil fans are all
functioning properly.
• Lights switch is accessible at case front-left, near
upright. See illustration below.
• Turn light switch on. All lights should come on at
the same time. First time lighting may require a
short warm up-period for the bulbs.
• Slightly dim or a flickering of new bulbs is normal.
Digital Thermometer
• If lights do not turn on, check all raceway
plugs. The lighting is wired in series so all
lights must be plugged in or receptacles
capped in order for the case to light.
• Refrigeration section has been tested to
maintain temperature at or below 5 °Celsius /
41 °Fahrenheit.
• Note: Thermometers provided with equipment
reflect internal air temperature only (not actual
food temperature). Use probe thermometers to
determine actual product temperatures.

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 header),
attach by placing LED in base of clip and then snapping into
clip at FLANGE SIDE.
