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

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.
LBN Horizontal Merchandisers
1-2 InstallatIon
SELF CONTAINED (LOCATION)
LBN-4, 6, 7 and 8 each have front condenser
air intake and discharge. Maintain a minimum
clearance distance of two feet in front of the
merchandiser so that air discharge and air intake
is not obstructed.
LBN-10 requires a 2 inch minimum clearance
behind the merchandiser. A 24 in. clearance
must be maintained in front of the merchandiser,
because air flows through the front condensing
unit compartment.
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
The LBN series are low temperature, self-contained cabinets designed for pre-packaged
foods at below freezing temperatures. Design
features include non-heated glass lids, foamed
in place non-CFC insulation, interior mirrors,
reflectors, front-air discharge condensing unit,
(except LBN-10) and a balanced refrigeration
system for energy-saving performance.
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.
Do not walk on case. Do not put
ammable items atop the unit.
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 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.
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.
Do NOT remove shipping crate until the
merchandiser is positioned for installation.

MERCHANDISER LEVELING
Be sure to position merchandisers prop-
erly. 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. A slight pitch from front to
back is desirable. The cabinet back should
never be higher than the front.
COMPRESSOR
The compressor is banded for shipping.
Remove the two bolts holding the compressor
bar in place. Pull out the condensing unit.
Cut the steel band, which holds down the
compressor during shipment. The compressor should now float freely on the mounting
springs. DO NOT LOOSEN NUTS.
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 left-hand end
of the case interior, and a second one in the
condensing unit compartment. The serial plate
contains all pertinent refrigeration and electrical information. The serial plate should not be
removed for any reason.

REFRIGERATION UNIT ACCESS
The louvered access panel on the lower right
front of the cabinet provides access to the
condensing unit and electrical box.
Access
Panel
There is alo a rear access panel that covers the
rear of the condensing unit compartment. This
panel can be removed to gain access to the
back compartment.
DRAIN TRAP
Drain Trap may be accessed by removing the
rear access panel that covers the rear of the
compressor compartment.
The drain trap should be filled with water.
This
prevents warm air from migrating back
through the drain to the evaporator coil.
Failure to fill the trap with water, could result
in excessive frosting of the evaporator coil.
For the LBN-10, the back panel is a metal rear
panel with slots, which allows discharge air
to flow through the condensing unit compartment. Before removing this panel, make sure
the power supply to the cabinet is disconnected.
SEALING MERCHANDISER TO FLOOR
Rear Access Panel Removed
— LOCK OUT / TAG OUT —
To avoid serious injury or death from electrical shock, always disconnect the electrical
power at the main disconnect when servicing
or replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
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
maintenance of the condensing unit.
NOTE: Do not allow trim to cover any intake
or discharge grilles located in the lower front
panel.

ELECTRICAL / REFRIGERATION
MERCHANDISER ELECTRICAL DATA
Refer to Appendix A of this manual or the
merchandiser’s serial plate for electrical
information.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified.
ALWAYS CHECK THE SERIAL PLATE FOR
COMPONENT AMPERES
ELECTRICAL CONNECTIONS
LBN-4, 6, 7 and 8 models have a power cord
attached to the unit with a ground prong. The
cord is rated 115V/15Amp. The LBN-7 and 8
also require a circuit breaker or a time delay
fuse rated at 15 Amps for the circuit being
run to them. The LBN-10 has both a 115V &
208/230V circuit. The LBN-10 is hard wired,
and connections are made in 2 x 4 handy box.
All of these models are 60 hz, 1 ph. Connecting
this unit to any electrical supply other than
specified on the serial plate will void the warranty and may result in serious damage to the
unit. The cabinet should be supplied with its
OWN service.
POWER SWITCH
The power switch is located at the electrical
box that is behind the front, louvered access
panel. A slot in one of the louvers allows
access to the switch. The switch will shut off
all power to the cabinet for all LBN models.
Power
Switch
ELECTRICAL BOX
(Control Options)
LBN 4,6,7,8 models have 2 control options.
The standard option uses electro-mechanical
controls, consisting of a timer / defrost clock,
thermostat and power switch.
An optional electronic SNIII control, display,
and compressor & defrost power relays.
Both options are located in the electrical box.
This box is capable of sliding out for servicing
convenience. Access is gained by removing the
cover on the side of the box.
Merchandiser must be grounded.
Do not remove the power supply cord ground.

ELECTRICAL OUTLET:
Before the merchandiser is connected to any
wall circuit, use a voltmeter to check that the
outlet is at 100% of the rated voltage. The wall
circuit must be dedicated for the merchandiser. Failure to do so voids the warranty. Do
not use an extension cord. Never plug in more
than one merchandiser per electrical circuit.
• Always use a dedicated circuit with the
amperage stated on the unit.
• Plug into an outlet designed for the plug.
• Do not overload the circuit
• Do not use long or thin extension cords.
Never use adapters.
• If in doubt, call an electrician.
REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The correct
type of refrigerant will be stamped on each
merchandiser’s serial plate. The merchandiser refrigeration piping is leak tested. The
unit is charged with refrigerant, and shipped
from the factory with all service valves open.
LBN-6, 7, 8 and 10 models have a refrigeration
system that uses a semi-hermetic compressor.
LBN-4 uses a hermetic compressor. LBN
systems use a capillary tube for refrigerant
control. The capillary tube is soldered to
the suction line pull-out coil for proper
heat exchange. If the capillary should become
plugged or damaged, it is best to replace the
heat exchanger.
LBN-10 is hard wired - no power cord.
Risk of Electric Shock. If cord or plug
becomes damaged, replace only with
a cord and plug of the same type.
Refrigeration lines are under pressure.
Refrigerant must be recovered before
attempting any connection or repair.
IN STALLE R
It is the contractor’s responsibility to
install merchandiser(s) in accordance with
all local building and health codes.

P/N 0514392_G 2-3
WATER OUTLET AND WATER SEAL
The condensate water outlet is located on the
rear right side of the merchandiser. The outlet
has a factory installed, external water seal.
Attached to the water seal or external drain
is a black rubber drain hose. At the end drain
hose is a copper water trap. This water trap
drains into the condensate evaporator pan
located beneath the merchandiser. Ensure the
drain hose is properly trapped, and the drain
area is not clogged.
NOTE: All lower base panels must be in place
when the refrigerator is operating. If not, airflow from the condenser will be directed over
the evaporator pan and defrost water in the
pan may overflow.
REFRIGERATION CONTROLS
These merchandisers come standard with
electromechanical temperature control and
time clock. Defrosts are time-initiated and
temperature terminated. Optional electronic
controls are available.
