HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A. Self-Contained Merchandisers
HUSSMANN PRODUCT CONTROL
The serial number and shipping date of all
equipment is recorded in Hussmann’s files for
warranty and replacement part purposes. All
correspondence pertaining to warranty or
parts ordering must include the serial number
of each piece of equipment involved. This is to
ensure the customer is provided with the
correct parts.
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.
Separately packaged accessories such as kits and
shelves should be carefully unpacked. Check for
damage before discarding packaging.
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, the
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 from
receipt of equipment.
SHORTAGES
Check your shipment for any possible shortages
of material. If a shortage should exist and is
found to be the responsibility of Hussmann,
notify Hussmann. If such a shortage involves
the carrier, notify the carrier immediately and
request an inspection. Hussmann will acknowl-
edge shortages within ten days from receipt of
equipment.
LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where tem-
perature 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.
INSTALLATION
Do not walk or put heavy objects on case.

1-2 INSTALLATION
Product should always be maintained at proper
temperature. This means that from the time the
product is received, through storage, prepara-
tion and display, the temperature of the
product must be controlled to maximize the
life of the product.
The exterior frames of these merchandisers
provide space 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 or ventilation
kit.
BE SURE TO POSITION SELF-CONTAINED
MERCHANDISERS PROPERLY
. Self-contained
models have vented base panels to allow air
circulation through the condensing unit.
Allow for a minimum
4 in. clearance from
walls, merchandisers,
and any other large
objects near the
merchandiser’s back
side. Blocking or
restricting air flow
will adversely affect
performance and
may damage the
refrigeration system.
Merchandiser(s) must be free of obstruction in
front and above to maintain proper air flow.
There is no spacing requirement at sides of
merchandiser.
UNLOADING
Move the merchandiser as close as possible to
its permanent location. Remove the top of the
crate and detach walls from each other. Lift
crate from the skid. Unbolt the merchandiser
from the skid.
The merchandiser can now be lifted off the
crate skid. Lift only at the base of skid!
Remove any braces and/or skids attached
(blanket wrapped merchandiser may have
skids). Improper handling may cause damage
to the merchandiser when unloading. To avoid
damage:
1. Do not drag the merchandiser out of the
trailer. Use a Johnson bar (mule).
2. Use a forklift or dolly to remove the
merchandiser from the trailer.
EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious
personal injury could occur. THEY ARE NOT
STRUCTURALLY DESIGNED TO SUPPORT EXCES-
SIVE EXTERNAL LOADING such as the weight
of a person. Do not place heavy objects on
the merchandiser.
MERCHANDISERS SHIPPED WITH
ENDS INSTALLED
Be careful not to damage the factory installed
ends while moving the merchandiser. Make
sure that tools are positioned past the end and
beneath the model’s support bar.
P/N 0518279_A U.S. & Canada 1-800-922-1919 • Mexico 1-800-522-1900 • www.hussmann.com
Do NOT remove shipping crate until the
merchandiser is positioned
for installation.

SHIPPING BRACES
Move the merchandiser close to its permanent
location, and then remove all packaging.
Remove all separately packed accessories such
as kits and shelves. Remove the shipping bolts
attached to the shipping braces on each side of
the merchandiser. Discard these long bolts.
Open the parts bag(s) taped to the inside of
each end.
Fasten the washers and bolts to the threaded
inserts on the outside of each end. Install plug
button caps over end bolt holes.
MERCHANDISER LEVELING
Merchandiser(s) must be installed level to
ensure proper operation of the refrigeration
system, and to ensure proper drainage of
defrost water.
It is imperative that merchandisers be leveled
from the front to back and side to side. Leveling
the merchandiser correctly will solve most
operating problems.
1. Check floor where merchandisers are to set
to see if it is level. Determine where the highest
part of the floor is. Merchandisers will be
leveled off this point.
2. Using store legend, measure off and mark
on floor the exact dimensions of the merchan-
diser footprint. Snap chalk lines for front and
back position of base rail. Mark location of
each joint front and back. Use a transit to find
the highest point along both lines. Mark the
difference, then place the appropriate number
of shims required to maintain high-point level.

SERIAL PLATE LOCATION
Direct a flashlight through the return air grille
to locate the serial plate. BE SURE TO POSITION
WIDE ISLAND MERCHANDISER FRONTS PROPERLY.
The front of self-contained merchandiser is
readily identified by the location of the serial
plate affixed to the inside of the left front
assembly.
CASTERS AND LEG LEVELERS
The merchandiser may be equipped with
optional casters and optional leg levelers. If
the merchandiser has optional casters as
shown below, use the brake to lock the
merchandiser in place.
If the merchandiser has standard leg levelers,
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 merchandiser is level
front-to-rear. If it is not, turn each front corner
leveler up or down the same amount of turns
until the merchandiser is level front-to-rear.

INSTALL RETURN AIR GRILLES
Remove the return air grilles that are packed
inside of the merchandiser, and install them in
the fitted slots below the display racks as
shown below.
SPLASHGUARDS AND PANELS
Ensure the merchandiser has been leveled and
all electrical and refrigeration work is complete
before installing splashguards and panels. Refer
to Section 2 for electrical and refrigeration
information.
See page 1-7 for an exploded view of how
brackets, panels and splashguards fit onto the
merchandiser.
Install Splashguard Brackets
Position splashguard brackets first. Remove
the splashguard brackets from the plastic bag
shipped with the merchandiser. Position the
brackets on the merchandiser level to the floor.
Each bracket has a 11/2in. (38 mm) slot at the
rear of the bracket where it attaches to the
merchandiser. Tighten screws to secure the
brackets.
NOTE: The longer brackets are used at the
front of the merchandiser. The shorter brackets
are used at the sides of the merchandiser.

Before beginning installation, carefully
unpack and inspect the Light Bar Kit
making sure there is no breakage or
damage.
Note: Make sure that Light Bar Kits
are installed before placing cases in
lineup.
Caution: Remove fasteners from
studs and reattach to one bracket
at a time. Failure to do this can cause
damage to the case.
1Remove Hex Nuts/Washers from studs on rear of case. Fasten the
Light Bar Mounting Brackets –1
to the rear upright frame assemblies by
sliding the holes over the studs and
fastening using the same nuts and
