such items as fans, heaters,
thermostats and lights.
Do not use mechanical devices
or other means to accelerate the
defrosting process.
Do not use electrical appliances
inside the food storage
compartments of the case(s).

UL LISTING
These merchandisers are manufactured to
meet ANSI/ UL 471 standard requirements
for safety. Proper installation is required to
maintain the listing.
FEDERAL / STATE REGULATION
These merchandisers at the time they are
manufactured, meet all federal and state/
provincial regulations. Proper installation
is required to ensure these standards are
maintained.
Near the serial plate, each case carries a
label identifying the environment for which
the case was designed for use. For example:
ANSI/NSF-7 Type I
Display Refrigerator / Freezer intended
for 75° F (24° C) / 55% RH Ambient
Application
ANSI/NSF-7 Type II
Display Refrigerator / Freezer Intended for
80° F / 55% RH Ambient Application
ANSI/NSF-7
Display Refrigerator Intended for Bulk
Produce
ABOUT THESE CASES
These cases are designed to be ready for
remote installation of a top-mounted, air-
cooled condensing unit. See Section 2 of
this manual for installation of field-installed
condensing unit.
The case is programmed for medium
temperature use, and settings can be adjusted
using the controller keypad. Lighting is not
standard but offered as a option.
LOCATION
These merchandisers are designed for
displaying products in air conditioned
stores where temperature is maintained at
or below the ANSI/NSF-7 specified level
and relative humidity is maintained at or
below 55%.
Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efficiency.
Like other display cases, these are sensitive
to air disturbances. Air currents passing
around cases will seriously impair their
operation. Do NOT allow air conditioning,
electric fans, open doors or windows, etc. to
create air currents around the cases.
Excessive ambient conditions may cause
condensation and therefore sweating of
doors. Facility operators should monitor
doors and oor conditions to ensure safety
of persons.
To prevent sweating on the exterior
surfaces of merchandisers, there must be
aminimum clearance of 4 inches (102
mm)between the merchandisers and other
fixtures or walls. Product should always
be maintained at proper temperature. This
means that from the time the product is
received, through storage, preparation and
display, the temperature of the product
must be controlled to maximize the life of
the product.

SHIPPING DAMAGE
All equipment should be thoroughly
examined for shipping damage before and
during unloading. This equipment has been
carefully inspected at our factory. Any
claim for loss or damage must be made to
the carrier. The carrier will provide any
necessary inspection reports and/or claim
forms.
Apparent Loss or Damage
If there is an obvious loss or damage, it
must be noted on the freight bill or express
receipt and signed by the carrier’s agent;
otherwise, carrier may refuse claim. The
carrier will supply necessary forms.
Concealed Loss or Damage
When loss or damage is not apparent
until after equipment is uncrated, a claim
for concealed damage is made. Upon
discovering damage, make request in writing
to carrier for inspection within 15 days and
retain all packing. The carrier will supply
inspection report and required claim forms.
EXTERIOR LOADING
Do NOT walk on top of case(s) or damage
to the case(s) and serious personal injury
could occur. They are not structurally
designed to support excessive external
loading such as the weight of a person.
LIFTING AND MOVING THE CASE
The case can be moved with pallet jacks
and/or j-bars. Use the sheet metal lifting
brackets as shown below. The brackets are
at each end of the case. Position the jacks or
j-bars underneath these lifting brackets for
transit to the final location.
Be careful not to damage the ends of the
case when positioning and moving. The
edge guard can be removed if needed.
REMOVE SHIPPING RIDERS AND
BRACKETS
There are two 2"x 8"shipping riders that lift
the case about a ¼" off of the floor. They
are installed in the front and rear bottom
interior. The riders are bolted to the case
with sheet metal brackets. Remove the
riders and brackets.
Do not store items or ammable materials
atop the unit. Do not walk on case.

LEVELING
Merchandisers must be installed level to ensure proper operation of the refrigeration
system and to ensure proper drainage of defrost water. When leveling merchandisers, use a
carpenter’s level. Leveling shims or wedges are provided with each merchandiser for use if
needed.
NOTE: BEGIN LINEUP LEVELING FROM THE HIGHEST POINT OF THE STORE FLOOR.

Base Component
The front shipping rider can be positioned
at the front of the two end base uprights in
order to help square and align the base for
drilling to floor.
Place shims under the end bases if the floor
is not level. Use a 4 ft level to make sure the
case is level.
Placing shims at other locations will cause
uneven distribution of weight leading to
piping leaks, as well as sagging or wracked
doors.
Supports must be shimmed if not in full
contact with the floor.

CASE-TO-CASE JOINING
Sectional construction means that two
or more merchandisers may be joined in
line yielding one long continuous display
requiring only one pair of ends. Joining
kits and instructions are shipped with each
merchandiser. Use the packaged hardware in
the hardware joining kit.

ALIGN END FRAMES AND JOIN CASE ENDS TOGETHER
Cases are joined from left to right. Move the second case (case on right side facing the
front) as close to the first as possible by using a j-bar or pallet jack.
Case joining covers must be removed. Use the joining locations as shown in the illustration
below. Loosely fasten cap screws, washer and nut retainers at all locations. Tighten the
rear and bottom locations first. Note there is a joining bracket on top of the case canopy as
shown in the detail below. Tighten that locations last.
ALL JOINTS MUST BE AIR-TIGHT TO PREVENT
FORMATION OF ICE OR CONDENSATION.

SECURING CASE TO FLOOR
The case must be secured to the floor using anchors that are fastened to the two end base
uprights.
1. Use a square. It is important to make sure the end base uprights are 90° from the back-
foam assemblies before installing the 6 anchor bolts in the concrete.
2. Use a hammer drill to drill ½" diameter holes 2¾" inches deep in the concrete. (3 on
each end of the case.) Clean out concrete dust from holes.
3. Install the ½" diameter anchor bolts. Tighten nuts to secure case to the floor.
