NSF CERTIFICATION
These merchandisers are manufactured to meet
ANSI / National Sanitation Foundation (NSF®)
Standard #7 requirements. Proper installation is
required to maintain certification. Near the serial
plate, each case carries a label identifying the
type of application for which the case was certi-
fied.
ANSI/NSF-7 Type I – Display Refrigerator / Freezer
Intended for 75°F / 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
LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where tempera-
ture 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 sun-
light, near hot tables or near other heat sources
could impair their efficiency.
Like other merchandisers, these are sensitive to air
disturbances. Air currents passing around mer-
chandisers will seriously impair their operation.
Do NOT allow air conditioning, electric fans,
open doors or windows, etc. to create air currents
around the merchandisers.
To prevent sweating on the exterior surfaces
of merchandisers, there must be A MINIMUM
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 unload-
ing.
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 neces-
sary 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.

INSTALLATION
Do not walk or put heavy objects on case.
CAUTION
!

EXTERIOR LOADING
Do NOT walk on top of merchandisers or dam-
age to the merchandisers and serious personal
injury could occur. THEY ARE NOT STRUCTURALLY
DESIGNED TO SUPPORT EXCESSIVE EXTERNAL
LOADING such as the weight of a person. Do not
place heavy objects on the merchandiser.
MERCHANDISERS SHIPPED WITH END
INSTALLED
If the case was shipped with the end installed,
two long bolts were used to hold the shipping
brace to the end. If the shipping bolts are
reinserted after removing the brace, they will
extend into the product area and may damage
the coil. THEREFORE, BE SURE TO REPLACE
THESE BOLTS WITH THE SHORTER BOLTS
PROVIDED.
Be careful not to damage the factory-installed
end while moving the merchandiser. Make sure
that tools are positioned past the end and beneath
the merchandiser’s support bar.
SHIPPING BRACES
Move the merchandiser as close as possible to its
permanent location and then remove all packag-
ing. Check for damage before discarding packag-
ing. Remove all separately packed accessories
such as kits and shelves.
Locate the shipping block in the
center of the heat exchanger (see
illustration), and remove it before
piping the merchandiser. This
block was installed to minimize
shipping vibration.
REMOVE FRONT PANEL
(DOES NOT APPLY TO RLT)
Before setting case, remove the front panel as
follows: remove screws from front panel tabs,
then lift the front panel. Refer to the illustration
below. Set panel and screws aside to reinstall
once all electrical work is complete.
At completion of all electrical work, installation
contractor shall re-install the panels using care to
ensure all panels are centered and properly
fastened.

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 as shown.
Metal 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.
Place shims under the rail and make
sure that they are positioned at a base
component (crossbar). This transfers
the weight directly from the loaded
case through to the floor. Placing shims
at other locations will cause uneven
distribution of weight leading to piping
leaks, as well as sagging or wracked
doors.

DOOR ADJUSTMENT
After leveling and joining the merchandisers,
adjust and level doors according to manufacturer’s
instructions shipped with each product. Factory
settings are lost due to vibration during shipment.
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.
To join like fixtures, a joining kit is required.
To join unlike fixtures, or like fixtures operating
at different temperatures, a 11/2inch (38 mm)
partition kit is required. To join same
temperature fixtures on different defrost cycles,
a plexiglass partition kit is required.
ALL JOINTS MUST BE AIR-TIGHT TO PREVENT
FORMATION OF ICE OR CONDENSATION.
Refer to separate joining instruction shipped
with each case
INSTALLING SPLASHGUARD BRACKETS
1. Attach splashguard retainer and splashguard
retainer support to splashguard support brack-
et using two screws per bracket.
2. INSTALL SPLASHGUARD SUPPORT BRACKETS
BEFORE PIPING CASE.The leveling brackets
have a maximum extension of one (1) inch
(25 mm) for uneven floors.
DO NOT PLACE SHIMS UNDER SPLASHGUARD
BRACKETS.

INSTALLING BUMPERS
Offsetting the bumpers and top rails helps to
disguise the joint locations, giving the lineup a
smoother look.
Begin at the left end of the line-up. A starter
bumper is factory-installed with end kits. Insert
the internal joint trim, then add the full-length
bumper.
Align each bumper section with its retainer and
push into place, working from the end of the line-
up. Install full length bumpers and internal joint
trims offset across joints. Make sure that no gaps
exist between sections. Continue installing
bumpers the length of the line up.
Do NOT install the last bumper sections at this
time. These sections will be installed in the last
step.
Once all except the last section of bumper have
been installed, refrigerate the case line-up for
at least six (6) hours. The last sections of
bumper should be kept inside a refrigerated
case or cooler during this time to allow the
bumpers to contract.
Before installing the last full-length section,
measure the remaining space. Use a miter box
and fine-tooth saw to cut last bumper to length.
Install the last section.
