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.
SHM Merchandisers
1-2 INSTALLATION
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.
B
E 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.

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.
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.
Do not walk or put heavy objects on case.
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.
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.
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.

1-4 INSTALLATION
MERCHANDISER LEVELING
E SURE TO POSITION MERCHANDISERS PROPERLY.
B
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.

P/N 0515154_E 1-5
NIGHT CURTAIN INSTALLATION
Night curtains are used to cover the case opening after normal business hours. The curtains
improve energy consumption, allowing the
refrigeration system to work less.
Night Curtain
Carefully inspect the night curtain kit to ensure
there is no damage from breakage during
shipping. Case should be positioned and
leveled before installing the night curtain.
Position night curtain on top panel. Measure
1.50 inches to edge of the end night curtain.
Center night curtain to length of case.
Fasten night curtain to top panel using (3) #8
x 1/2 in. screws.
