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.: 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.

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).

STOCKING / MAINTAINING PROPER PRODUCT CONDITION
A. Stocking
1. Product must always be maintained at a
constant and proper temperature. Thus,
from the time product is received, through
storage, preparation and display, product
temperature must be controlled to maximize
life of the product.
2. These units are not “rapid cool-down
cases”; they are “holding cases.” Thus,
product must be in its fully-refrigerated state
(at 41 °F or less) PRIOR to being placed in
cases to help maintain maximum shelf life of
product.
3. When stocking, never allow the product to
extend beyond the recommended load limit.
4. Air discharge and return air flow must be
unobstructed at all times to provide proper
refrigeration.
5. Product must be consistently rotated (older
product rotated to front of display) per your
store’s stocking protocol.
B. Maintaining Proper Product Condition
1. Improper temperature and lighting will
cause serious product loss. Discoloration,
dehydration and spoilage can be controlled
with proper use of the equipment and
handling of product.
2. To prevent product dehydration, do not
allow temperature to drop below range
specified in OVERVIEW section of this
manual.
3. Minimize processing time to avoid
damaging temperature rise to the product.
Product should be kept at proper
temperature.
4. Keep the air in and around the case area
free of foreign gasses and fumes or food
will rapidly deteriorate.
5. Do not place any product into these
refrigerators until all controls have been
adjusted and they are operating at the
proper temperature. Allow merchandiser to
operate at a minimum of 6 hours before
stocking with any product.
6. There are vents located at the base of the
front of the glass, just above the front rail.
These vents supply a continuous, gentle flow
of air across the front glass which inhibits
condensation. Do not place any signs, product
or other restrictive objects on the front of the
refrigerator that will block these vents.
7. Keep the service doors closed (when
applicable). Refrigeration performance will be
seriously affected if left open for a prolonged
period of time.
8. Avoid the use of supplemental flood or spot
lighting. Display light intensity has been
designed for maximum visibility and product
life at the factory. The use of higher output
fluorescent lamps (H.O. and V.H.O.), will
shorten the shelf life of the product.
9. Turn off case lights at night.
10.In the deli, meat and fish cases, completely
cover the product each night with a clean
damp cloth or butcher paper (never use
plastic, as it does not allow for proper
circulation). Make sure the cloth or paper is in
direct contact with the product.
11.Turn and rotate the meat fairly often. The
blood (which gives the pink color) works its
way downward with time.
12.Cold coils remove heat and moisture from the
case and deposit this as frost onto the coil.
Thus, you must thoroughly clean and defrost
the upper refrigeration system/gravity coil drip
tray assembly at least weekly. See
CLEANING SCHEDULE (INTERIOR) - TO
BE PERFORMED BY STORE PERSONNEL
section in this manual for cleaning and
defrosting specifics.
13.Understand product quantity and how it
effects dehydration. The only other moisture
within the case is that of the product itself.
Thus, a single level of meat will dry out faster
than a fully loaded case of 3-4 levels of meat.
