INSTALLATION
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
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.
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 response to the
carrier for inspection within 15 days.
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%.
Recommended operating ambient
temperature is between
65°F (18°C) to 75°F (23.9°C).
Maximum relative humidity is 55%.
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.
HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efficiency. Like
other merchandisers, these merchandisers 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
merchandiser.

SELF CONTAINED LOCATION
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.
Be sure to position self contained
merchandisers properly.
SELF CONTAINED models have vented base
panels to allow air circulation through the
condensing unit.
See illustrations for clearances distances from
walls, merchandisers, and any other large
objects near the merchandiser’s vented base
panels. Blocking or restricting air flow will
adversely affect performance and may damage
the refrigeration system.
For California Businesses:
This product may contain chemicals known
to the State of California to cause cancer,
birth defects, or other reproductive harm.
This warning is the result of the California State
law known as the California Safe Drinking Water
and Toxic Enforcement Act of 1986, which is
commonly referred to as “Proposition 65.”
This warning does not mean that Hussmann
products will cause cancer or reproductive
harm, or is in violation of any product-safety
standards or requirements. As claried by the
California State government, Proposition 65
can be considered more of a ‘right to know’ law
than a pure product safety law. When used as
designed, Hussmann believes that our products
are not harmful. We provide the Proposition 65
warning to stay in compliance with California
State law. It is your responsibility to provide
accurate Proposition 65 warning labels to your
customers when necessary. For more information
on Proposition 65, please visit the California
State government website.

MODEL DESCRIPTION
SHM merchandisers offer versatility for the
display of food items such as: fresh fruit,
vegetables, cheeses and other delicatessen
items. Carefully read and follow the instructions prior to operating the merchandiser.
UNLOADING
Unloading from Trailer:
Lever Bar (also known as a Mule, Johnson
Bar, J-bar, Lever Dolly, or Pry Lever)
Move the merchandiser as close as possible to
its permanent location and remove all packaging.
Check for damage before discarding packaging.
Remove all separately packed accessories such
as kits and shelves.
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.
SHIPPING SKID
Each merchandiser is shipped on a skid to
protect the merchandiser’s base, and to make
positioning the case easier.
Do not remove the shipping skid until the
merchandiser is near its final location. The
skid provides protection for both the merchandiser and the floor.
Remove the skid by raising one end of the
merchandiser approximately 6 inches. Block the
merchandiser securely, and remove the two skid
bolts from the raised end. Replace the bolts
with (provided) leg levelers. Repeat this procedure at opposing end. Once the leg levelers are
secured in place, the merchandiser may be slid
off the skid and placed in its final location.
DO NOT TILT MERCHANDISER ON ITS
SIDE OR END WHEN REMOVING SKID.
Once the skid is removed, the merchandiser
must be lifted —NOT PUSHED— to reposition.
Check floor where merchandisers are to be set
to see if it is a level area. Determine the highest
part of the floor.
EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious
personal injury could occur.
merchandisers are not structurally
designed to support excessive external
loading such as the weight of a person. Do
not place heavy objects on the merchandiser.
HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
Do NOT remove shipping crate until the
merchandiser is positioned
for installation.
Do NOT stand or walk on top of
merchandiser. Do not store items or
ammable materials atop the unit.

MERCHANDISER LEVELING
Be sure to position merchandisers proper-
ly. Level the merchandiser by all four corners.
Merchandiser(s) must be installed level to
ensure proper operation of the refrigeration
system, and to ensure proper drainage of
defrost water. Optional leg levelers can be
provided for this purpose.
OPTIONAL LEGS
®
NSF
approved legs replace the leg levelers if
required by local health codes. The legs raise
the case 6 inches for cleaning purposes. An
optional skirt kit can be provided to snap on
the legs.
SERIAL PLATE LOCATION
The serial plate is located on the interior left
wall of the merchandiser. It contains all pertinent information such as model, serial number,
amperage rating, refrigerant type and charge.
This information will be needed to install, service
or order parts for the merchandiser.
REFRIGERATION UNIT ACCESS
The lower access panel may be removed by
lifting the panel straight upward and over the
screws on which it is hanging. The panel is
installed by reversing the above procedure.
Ensure lower access panel is flat against the
floor when installed to prevent air circulation
problems on self contained merchandisers.
Safe-NET III Display
Front Panel
Lift up and
out to remove
access panel
Safe-NET III display is
mounted on left side of
access panel. Be careful
not to detach Safe-NET III
cable from display when
removing access panel.
Safe-NET III

SEALING MERCHANDISER TO FLOOR
If required by local sanitary codes, or if the
customer desires, merchandisers may be sealed
to the floor using a vinyl cove base trim. The
size needed will depend on how much variation there is in the floor, from one end of the
merchandiser to the other. Sealing of the lower
front and rear panels on self contained models may hamper their removal for servicing or
Serial Plate
maintenance of the condensing unit.
NOTE: Do not allow trim to cover any intake
or discharge grilles located in the lower front
panel.
