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
certified.
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 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 merchandisers, these are sensitive to air
disturbances. Air currents passing around
merchandisers will seriously impair their
operation. Do NOT allow air conditioning,
electric fans, open doors or windows, etc. to
create air currents around the merchandisers.
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.
Excel merchandisers have internal frames.
A 3 inch (76 mm) space between the rear
of the merchandiser and wall must be
maintained for air circulation. However, in
high ambient conditions, sweating may
still occur. If this happens install a method
of forced ventilation such as a fan
ventilation kit.
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.
Concealed Loss Or Damage
When loss or damage is not apparent until after
equipment is uncrated, retain all packing materials
and submit a written request to the carrier for
inspection, within 15 days.
INSTALLATION
Do not walk or put heavy objects on case.
CAUTION
!
1-2 I
NSTALLATION
P/N 0463880_E WWW
.HUSSMANN.COM
UNLOADING
Improper handling may cause damage to the
merchandiser when unloading. To avoid damage:
1. Verify that adjustable feet are fully inserted
and securely positioned into the legs.
2. Do not drag the merchandiser out of the
trailer. Use a Johnson bar (mule).
3. Use one dolly to remove the merchandiser
from the trailer.
4. Use two dollies to move cases to lineup.
SERIAL PLATE LOCATION
Direct a flashlight through the return air grille to
locate the serial plate. B
E SURE TO POSITION WIDE
ISLAND MERCHANDISER FRONTS PROPERLY
. The
front of wide island merchandisers is readily
identified by the location of the serial plate
affixed to the inside of the left front assembly.
Since all electrical and refrigeration connections
will be made at the front side, the fronts will need
to be positioned according to the store plan layout.
EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious
personal injury could occur. T
HEY ARE NOT
STRUCTURALLY DESIGNED TO SUPPORT EXCESSIVE
EXTERNAL LOADING
such as the weight of a
person. Do not place heavy objects on the case.
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. T
HEREFORE, BE
SURE TO REPLACE THESE BOLTS WITH THE SHORTER
BOLTS PROVIDED
. NSF requires any bolt or screw
in the product area be capped or cut off if it has
more than three exposed threads.
NOTE:
Be careful not to damage the factory installed
end while moving the case. 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 packaging. Check for damage before discarding packaging. Remove all separately packed accessories
such as kits and shelves. Remove end braces and
discard hardware.
Do NOT remove shipping braces until
the merchandisers are positioned
for installation.
Serial Plate Behind

WARNING
SHIPPING RIDER
Each case is shipped on a rider to protect the factory
installed front legs, and to make positioning the case
easier. DO NOT remove the front rider until the
case has been positioned. Once the rider is
removed, the case must be lifted –NOT PUSHED–
to reposition. To remove the rider, remove bolts
attaching rider to each leg.
Set all adjustable legs to the mid-point before
attempting to level the case.
CASE LEVELING
Merchandisers must be installed level to ensure
proper operation of the refrigeration system and
to ensure proper drainage of defrost water.
During all steps of setting, joining and leveling
cases, close attention to position and operation
must be maintained.
NOTE: B
EGIN LINEUP LEVELING FROM THE HIGHEST
POINT OF THE STORE FLOOR
.
Preparation
1. Using store blueprints, measure off and mark
on floor the exact dimensions/locations of the
case footprint. A 3 inch space is required
behind each case to prevent condensation.
2. Snap a chalk line for the front and rear
positions of the base legs.
3. Mark the location of each joint from front to
back lines.
4. FLOORS ARE NOT LEVEL!!! When
working with two or more cases to be joined, the
whole lineup must be leveled on the same plane,
left to right and front to back. This means that the
entire lineup must be brought up to the level of
the highest case in the lineup.
Along the lines previously marked, find the
highest point of the floor by:
• Walking the floor and noticing any dips or
mounds;
• Using a string level; and
• Using a transit.
Leveling
Position the first case at the highest point on the
floor. Work outward from that point to create the
case line-up. Use a 48 inch (1220 mm) or longer
level for end-to-end leveling. The rear edge of the
top foam panel of the case is a good location for
the level at the rear of the case, and the top rail is
a good location for the level at the front of the
case. For leveling the case front-to-rear, a 24 inch
(610 mm) level should be placed on the lower
flange of the case end frame. If the case has a
factory installed end, the level should be placed
on the canopy support brackets on top of the
case. Suggested level locations are shown in the
following illustrations.

Level the case by all four corners. Start at the
rear by placing as needed the provided shims
under each end of the rear base rail. The shims
are long enough to allow the adjoining case to be
leveled with the same shim. When the rear of the
case is level end-to-end, move to the front of the
case. Use an 18 mm open end wrench to screw
down the levelers at each front corner so that the
front is also level from end-to-end. At this point,
check to see if the case is level front-to-rear. If it
is not, turn each front corner leveler up or down
the same amount of turns until the case is level
front-to-rear.
The case should be solidly supported at least
every 4 feet (1220 mm). Once the case is level, if
any gaps are present, shims should be inserted
under the rear base rail approximately in line
with the center front support legs to support the
rear of the case. At the front of the case, screw
down the levelers on each of the center support
legs so that they contact the floor and support the
front of the case.
NOTE: Do not place levels
on Display Pans or
on Shelves.

JOINING INSTRUCTIONS
Sectional construction means that two or more
cases may be joined in line yielding one long
continuous display requiring one pair of ends.
A
LL JOINTS MUST BE AIR-TIGHT TO PREVENT
FORMATION OF ICE OR CONDENSATION
.
Prep Case
1. Check to be sure that merchandisers are
level and that the factory-installed nut retainers
are in place. Locate the Joining Kit and check
contents.
2. Remove shelves (if installed), display racks,
pans and front air grilles from the right end.
3. Remove the rear interior panel(s) from the
right end. On multi-deck cases remove the lower
back panel first. To remove a panel, lift it up
from its bottom edge and out. No tools required.
Apply Gaskets as Follows:
Right End
1. Apply the 1 inch (25 mm) gasket around the
perimeter of the case as shown. It must be at the
edge. Check to be sure that there are no gaps
between gasket and merchandiser.
2. Apply the 1
5
/8 in. (41 mm) gasket so that one
edge is on the metal case frame and the parallel
edge laps the 1 inch gasket. Check to be sure
that there are no gaps between merchandiser and
gaskets.
