 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.

INSTALLATION, CONT’D: CASE ADJOINMENT INSTRUCTIONS
3. Case Adjoinment Instructions
>> Warranty is void if improper caulk/sealant is used.
>> Lay generous beads of caulk/sealant as specified.
A. Prior To Adjoinment - Apply Industrial Butyl
Caulk at Center of Uprights
 Lay a generous bead of industrial grade butyl caulk
at center of uprights (in non-visible areas).
 This butyl caulk 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 illustration below.
B. Adjoining Cases - Using Bolts and Nuts
 Use appropriately sized nuts and bolts for each hole.
#1 - Hole is accessible through upper front section or
rear sliding door (if able to avoid gas cylinder,
attach bolt); otherwise start at #2 in process.
#2 - Holes are accessible after rear plenum removal.
#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 or rear
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 illustrations below.
>> You must reattach toe-kick(s) and decking after case
adjoinment process is complete.

INSTALLATION, CONT.: LIFT-UP FRONT GLASS
 Gas cylinders will retain glass in raised position.
 Raised glass allows front access for product
re-stocking and/or cleaning purposes.
 Lower front glass slowly to prevent damage to unit.

4. Lift-Up Front Glass
 Check that front glass lifts up properly.
 Front glass may be raised 90° via hinge that is
located mid-case (as shown below)
 Carefully grasp lift handle and raise upward.

INSTALLATION, CONT.: FRAME SUPPORT RAIL SHIMMING
Note: Above Illustration May Not Depict An Exact
Representation Of Your Particular Unit Being Installed.
 Note: After case is in position, it must be
sealed to floor to prevent entry or leakage of
liquid or moisture.
 Caution: If glass scrapes against edges of case or
against each other, see INSTALLATION, CONT.:
FRONT GLASS ALIGNMENT section in this
manual.
5. 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.

INSTALLATION, CONT.: FRONT GLASS ALIGNMENT VIA FRAME SUPPORT RAILS
6. Front Glass Alignment & Adjustment via Frame Support Rails
 Proper alignment of the front glass is important to maintain a seal inside 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
case.
2. 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.
1. 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. Follow steps 3 and 4 below for specifics.
5. 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 shimming procedure until the front glass is properly aligned along both sides of the case.

7. Temperature Control
 Temperature is remotely controlled.
 Consult store management for guidance and
instructions.
8. Thermometer Placement & Purpose
 Lower section thermometer (self-service section)
is located against rear plenum.
 Upper section thermometer (service section) may
be located in rear storage bins above shelves (at
angled positions), however location may vary.
 Rear thermometers are in upper section just inside
rear doors (as shown below).
 Thermometers may be either spirit-filled or
digital. They reflect internal air temperature only
(not actual food temperature).
 Use probe thermometers to determine actual
product temperatures.
9. Temperature Probes
 Thermometer/thermostat probes are positioned
horizontally (behind probe plate) in lower, self-
service section rear plenum (shown below-left).
 Probes are suspended by spacer/screw
assembly, allowing probes to garner accurate
temperature readings and transmit readings as
required.
