OVERVIEW AND WARNINGS
OVERVIEW
• These Structural Concepts Encore® service cases are designed to merchandise product at 5°C / 41°F
or less product temperatures.
• These cases should be installed and operated according to this operating manual’s instructions to
insure proper performance. Improper use will void warranty.
This unit is designed for the display of products in ambient store conditions where temperatures and
humidity are maintained within a specific range.
• For NSF® Type 1 Conditions (most cases): ambient conditions are to be at 55% max. humidity / 75°F.
• For NSF® Type 2 Conditions: ambient conditions are to be at 60% maximum humidity / 80°F.
• If unsure if your case is Type 1 or Type 2, contact Structural Concepts Technical Service (see
Technical Service section in this manual for phone number).
Caution: Do not allow air conditioning, electric fans, open doors or windows to create air currents
around display case as this may detrimentally affect proper case temperatures and operation.

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.
Slide Skid Out
Case can be repositioned with pallet truck when
front lower panel is removed. Blocking may be
necessary to obtain adequate height.
3A. Removing Angled Lower Front Panels
Upper panel support.
• Remove screws located behind upper
front panel.
Lower panel support.
Most applications, screws secure the
•
lower panel support (located below front
panel) to the unit.
See illustration at right.
3B. Removing Vertical Lower Front Panels
Front Panel Upper Support
• Lift Front Glass.
Remove the caps and screws holding
•
Deck Support in place.
Front Panel Lower Support
For most display cases, screws secure
•
Front Panel Lower Support to Base.
• Remove screws holding Front Panel
Lower Support to Display Case Base.
Vertical Lower Front Panel can now be removed (see
illustration at lower right).
*Alternate applications (for cases without lower panel
screws): Apply upward pressure to lower panel
support to disengage lower support panel tabs from
slots located in the base at both ends of the unit.
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.

10. Front Glass Alignment & Adjustment via Levelers
• 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.
1. Side-to-Side Leveling
to the front glass). Raise or lower either side of the case by rotating
levelers to center the level bubble (following steps 3 and 4 below).
Case with Curved
Front Glass
: Place level on top of display case (parallel
2. Front-to-Back Leveling
• Place a level on top of case,
perpendicular to front glass.
• Raise or lower either side of case by
rotating levelers to center the level
bubble (follow steps 3 and 4).
• Double-check the side-to-side level.

5. Verification:
• After adjusting
the levelers,
open and shut
the front glass.
• Verify again that
front glass is
properly aligned
at both left-hand
and right-hand
side of case.
• If not, repeat the
above procedure
until front glass is
properly aligned
along both sides
of case.
11. Front Glass Alignment & Adjustment
via Clamshell Allen Screw Adjustment
Caution! Glass is extremely heavy! Two
people may be required to perform this task.
• Make certain case is level and plumb.
• Lift glass to maximum upright position.
• Determine which side requires realignment.
• While maintaining tight grip on glass, loosen
the Allen screws nearest to misaligned side.
• Adjust the glass until properly positioned.
• Allen screws may now be tightened (taunt, but
not overly tightened lest glass breakage occur).
• If other side needs alignment, repeat steps
while maintaining grip on glass.
