UL LISTING
These merchandisers are manufactured to meet
ANSI/ UL 471 standard requirements for safety.
Proper installation is required to maintain the
listing.
FEDERAL / STATE REGULATION
These merchandisers at the time they are man-
ufactured, meet all federal and state/ provincial
regulations. Proper installation is required to
ensure these standards are maintained. Near
the serial plate, each merchandiser carries a
label identifying the environment for which the
merchandiser was designed for use.
ANSI/NSF-7 Type I – Display Refrigerator /
Freezer
Intended for 75°F (24°C) / 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 cor-
rect 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.
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%.
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.
INSTALLATION
Recommended operating ambient
temperature is between
65°F (18°C) to 75°F (24°C).
Maximum relative humidity is 55%.

SELF CONTAINED (LOCATION)
Product should always be maintained at proper
temperature. This means that from the time
the product is received, through storage, prepa-
ration and display, the temperature of the
product must be controlled to maximize the
life of the product.
Besure 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
vented base panels (for self contained models).
Blocking or restricting air flow will adversely
affect performance and may damage the refrig-
eration system.
Maintain 4-inch air
clearance at rear

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 dam-
age:
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 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 top of the crate and detach walls
from each other. Lift crate from the skid.
Unscrew the case from the skid. The fixture
can now be lifted off the crate skid. Lift only at
base of skid! Remove any braces and/or skids
attached (blanket wrapped merchandiser may
have skids).
DO NOT LAY MERCHANDISER OVER
ON THE FLOOR TO REMOVE SKID.
Once the skid is removed, the merchandiser
must be lifted —NOT PUSHED— to reposition.
To remove the skid, remove screws attaching
skid to the merchandiser.
Check floor where cases are to be set to see if
it is a level area. Determine the highest part of
the floor.
Do not walk or put heavy objects on case.
Do not place objects atop the unit.
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
Besure to position merchandisers properly.
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.
SERIAL PLATE LOCATION
The serial plate is located on the inside of the
merchandiser’s display area as shown below.
REFRIGERATION UNIT ACCESS
The rear panel may be removed by lifting the
panel straight upward and over the tabs on
which it is hanging.
Screws will have to be removed from either
end of the panel. The panel is installed by reversing
the above procedure. Ensure lower front panel
is flat against the floor when installed to prevent
air circulation problems.
