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.

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
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.
— LOCK OUT / TAG OUT —
Self-contained
models have
factory -installed
power cords
attached at the
electrical box.
All wiring must be in compliance with NEC
and local codes. All electrical connections (for
remote models) are to be made in the electrical
Handy Box located behind the removable base
panel at the left end of the merchandiser when
facing the discharge air louver.
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.
Risk of Electric Shock. If cord or plug
becomes damaged, replace only with
a cord and plug of the same type.
Merchandiser must be grounded.
Do not remove the power supply cord ground.
REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The
merchandiser refrigeration piping is leak
tested. The unit is charged with refrigerant
and shipped from the factory with all service
valves open.
HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
SHM Merchandisers
2-2 InstallatIon
REFRIGERATION
(Self Contained Models Continued)
SHM-3 self contained merchandisers use
R-404a refrigerant. SHM-4 self contained
merchandisers use R-134a refrigerant. All
models have a hermetic compressor. The
systems employ capillary tubes for refrigerant
flow 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.
Refrigeration lines are under pressure.
Refrigerant must be recovered before
attempting any connection or repair.
WATER OUTLET AND WATER SEAL
The condensate water outlet is located in the
center of the merchandiser. The outlet has a
factory installed, external water seal.
For self contained models, this water seal
drains into the condensate evaporator pan
located beneath the merchandiser. The pan
uses a thermistor that senses water in the pan
and adjusts the amount of heat required to
evaporate the water. 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.
When brazing pipes, be sure to use the
insulation blanket shipped with the
merchandiser to prevent damage to the
metal merchandiser bottom.

MAINTENANCE
CARE AND CLEANING
Long life and satisfactory performance of
any equipment is dependent upon the care it
receives. To ensure long life, proper sanitation
and minimum maintenance costs, these
merchandisers should be thoroughly cleaned,
all debris removed and the interiors washed

Interior Surfaces
The interior surfaces may be cleaned with most
domestic detergents, ammonia based cleaners
and sanitizing solutions with no harm to the
surface. Self contained models empty into a
limited capacity evaporation pan, which will
overflow if excess water is used in cleaning.

4-2 Maintenance
— 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.
CLEANING DISCHARGE HONEYCOMB
Discharge honeycombs should be cleaned
every six months. Dirty honeycombs will
cause merchandisers to perform poorly.
The honeycombs may be cleaned with a
vacuum cleaner. Soap and water may be used
if all water is removed from the honeycomb
cells before replacing. Be careful not to damage
the honeycomb.
1. Using a flat object such as a screw driver,
compress the honeycomb and remove it
from its retainer.
CLEANING STAINLESS STEEL SURFACES
Use non-abrasive cleaning materials, and
always polish with grain of the steel. Use warm
water or add a mild detergent to the water and
apply with a cloth. Always wipe rails dry after
wetting.
Use alkaline chlorinated or non-chlorine
containing cleaners such as window cleaners
and mild detergents. Do not use cleaners
containing salts as this may cause pitting and
rusting of the stainless steel finish. Do not use
bleach.
CLEANING UNDER STEP PAN
Remove all product from the merchandiser
and place in cooler. Always disconnect electrical power before cleaning.
1. Place a small screw driver between the
front grille and step pan. Gently lift the
step pan’s front lip up. Grasp the step pan
with both hands to remove. Always wear
gloves when removing step pan.
2. Clean and dry the honeycomb.
3. After cleaning, replace in reverse order.
Damaged honeycomb must be replaced.
2. Use non-abrasive cleaning materials and a
mild detergent to clean the step pan.
3. Wipe down the insides of the merchandiser
with a mild detergent, and replace step
pan.
DO NOT FLOOD!
Use only enough water necessary to clean
surface. Water must not drip down the case!
Never use ammonia based cleansers, abrasive
cleansers, or scouring pads.

Step Pan
P/N 0515258_J 4-3
CLEANING THERMOMETER
Remove the two screws holding the thermometer
to its mounting bracket. Remove the sensing
element from its clip. Clean the element with
water and mild detergent solution. Ensure the
sensing element is wiped clean of any residue to
ensure proper temperature readings.
Airflow blockage increases energy consumption and reduces the merchandiser’s ability to
maintain operating temperature.
SHUT FANS OFF DURING
CLEANING PROCESS.
Do NOT use HOT water on Cold glass Surfaces.
This can cause the glass to shatter and could
result in personal injury. Allow glass fronts, to
warm before applying hot water.
CLEANING COILS
Condenser coils should be cleaned at least
once per month. Additional cleaning may be
needed depending on the operational environment. A dirty condenser blocks normal airflow
through the coils.
NEVER USE SHARP OBJECTS AROUND
COILS. Use a soft brush or vacuum brush to
clean debris from coils. Do not puncture coils!
Do not bend fins. Contact an authorized
service technician if a coil is punctured,
cracked, or otherwise damaged.
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris. Do not bend
coil fins. Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles.
ICE in or on the coil indicates the refrigeration and defrost cycle is not operating properly. Contact an authorized service technician
to determine the cause of icing, and to make
adjustments as necessary. To maintain product
integrity, move all product to a cooler until
the unit has returned to normal operating
temperatures.

4-4 Maintenance
CLEANING EVAPORATION PAN
(SELF CONTAINED ONLY)
The condensate water outlet for self contained
models empties into a limited capacity evaporation pan.
Debris or dirt accumulation inside the condensate evaporation pan or on the heater coil will
reduce the pan’s evaporation capacity and
cause premature heater failure. The evaporation
pan waste water will overflow and spill onto the
floor if the heater is not properly operating.
Remove accumulated debris from the evaporation
pan. Wipe down heater coil with a cloth and
warm water. Be sure to remove any dirt, debris
or liquids from the heater coil.
Water introduced during cleaning will cause
the evaporation pan to overflow.
Evaporation Pan is Hot!
and poses risk of bodily injury – Always Wear
gloves and protective eye wear when servicing.
Turn off evaporation pan heater, and allow pan
to cool.
MAINTAINING FLUORESCENT LAMPS
(FOR OPTIONAL LIGHT BAR KIT)
Fluorescent lamps should not be allowed to
run to failure. If a re-lamp schedule is not in
place, the tubes should be inspected for signs
of degradation (blackened ends). Degraded or
failed tubes should be replaced.
Allowing severly degraded lamps to operate
may cause a ballast failure or could expose
the lamp holder to excessive heat. Replacing
degraded bulbs is more cost effective
than replacing ballast and lamp-holders.
Traditional re-lamp programs are 18-to-24
month intervals. In the absence of a re-lamp
program, a yearly inspection of the lighting
system is recommended.
1. Inspect all lamp sockets and plug-receptacle
connections for signs of arching. Replace any
component that shows signs of arching.
2. Make sure all unused receptacles have their
close-off covers securely installed.
3. Make sure proper cleaning procedures are
followed. Lights and fans MUST be turned off
when a case is cleaned and MUST be allowed to
dry before turning power back on.
4. Do not use a pressure nozzle to clean inside
of case.
REMOVING SCRATCHES FROM
BUMPER
Most scratches and dings can be removed
using the following procedure.
1. Use steel wool to smooth out the surface
area of the bumper.
2. Clean area.
3. Apply vinyl or car wax and polish surface
for a smooth glossy finish.
