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 75°F / 55% RH Ambient Application
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%.
SN recommended operating ambient
temperature is between
65°F (18°C) and 75°F (26.7°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.

SM recommended operating ambient
temperature is between
65°F (18°C) and 75°F (26.7°C).
Maximum relative humidity is 55%.
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.
SM / SN Spot Merchandisers
1-2 InstallatIon
SELF CONTAINED (LOCATION)
SM / SN models have a condensing unit that
draws ambient air through one side of the unit
and discharges hot air out by the opposite side.
In order to maintain refrigeration performance
and compressor life, a minimum space of
4 inches must be maintained between the
merchandiser and surrounding surfaces.
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
SN models are designed for low temperature
application and can be used for frozen
food products. These models have glass lids
with coating that maintains the lids free of
condensation.
SM models are open-top merchandisers,
designed for low temperature operation. These
models are designed with
a cold wall refrigeration system. The air
circulation inside the merchandiser is
provided by natural convection.
UNLOADING
Unloading from Trailer:
Use a 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.
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 external loading
such as the weight of a person. Do not place
heavy objects on the merchandiser.
SHIPPING SKID
Each merchandiser is shipped on a skid to
protect the merchandiser’s base, and to make
positioning the case easier.
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.
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.
Do NOT stand or walk on top of
merchandiser. Do not store items or
ammable materials atop the unit.
HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
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.
Do NOT remove shipping crate until the
merchandiser is positioned
for installation.
