LOCATION
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature and
humidity are maintained at or below 75°F and 55% rela-
tivehumidity.DO NOTallowair conditioning,electricfans,
ovens, open doors or windows (etc.) to create air cur-
rents around the merchandiser,as this will impair its cor-
rect operation.
Product temperature should always be maintained at a
constant and 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 life of the product.
UNCRATINGTHE STAND
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid.The fixture can now be lifted off the
crate skid.Lift only at base of stand!
EXTERIOR LOADING
Thesemodels have not been structurallydesigned tosup-
port excessive external loading. Do not walk on their
tops;This could cause serious personal injury and dam-
age to the fixture.
SETTING AND JOINING
The sectional construction of these models enable them
to be joined in line to give the effect of one continuous
display.A joint trim kit is supplied with each joint.
LEVELING AND PLACEMENT
IMPORTANT! It is imperative that cases be lev-
eled from front to back and side to side prior to
joining.
NOTE: A. To avoid removing concrete flooring, begin lineup
leveling from the highest point of the store floor.
B. When wedges are involved in a lineup, set them first.
All cases were leveled and joined prior to shipment to
insure the closest possible fit when cases are joined in the
field.When joining, use a carpenters level and shim legs
accordingly. Case must be raised correctly, under legs
where support is best,to prevent damage to case.
1. Checklevelof floor wherecases areto beset.
Determinethe highest point of the floor;cases will
beset off this point.
2. Setfirst case,andadjustlegs overthe highest part of
thefloor so that case is level.Prevent damage –case
must be raised under legor by use of2x6 or 2x4 leg
brace.Removeside andbackleg braces after case is
set.
3. Setsecond case as closeaspossible to the firstcase,
andlevelcase tothefirst using the instructions in
stepone.

CORNERWEDGES
If a wedge is used in the middle of the lineup,the wedge
must be set off the highese point on the floor FIRST,with
the rest of the lineup being leveled from that point.
If an outside corner display is used, it must be mounted
and set before attaching any joint trim parts.Set the front
stainless steel bumper so it aligns with bumpers on the
twocases.

WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the fixture.
A 1-1/2" P-trap and threaded adapter are supplied with
each fixture.The P-trap must be installed to prevent air
leakage and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se-
riously interfere with the operation of this refrigerator,
andresultin costlymaintenanceand productlosses.Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Neveruse pipe forcondensate drains smaller than
thenominal diameter of the pipe or P-trapsupplied
withthe case.
2. Whenconnecting condensate drains,the P-trap
mustbe used as part of the condensate drain to
preventair leakageorinsect entrance.Storeplumb-
ingsystem floor drains should be at least 14"off the
centerof the case to allowuse of the P-trappipe
section.Neveruse twowater seals in seriesin any
oneline.Double P-trapsin series will causealock
andpreventdraining.
3. Always provideasmuch downhill slope (“fall”) as
possible;1/8"per footis the preferredminimum.
PVCpipe,when used,mustbe supportedto main-
tainthe 1/8" pitch and to preventwarping.
4. Avoidlong runs ofcondensatedrains.Long runs
make itimpossible to provide the“fall” necessaryfor
gooddrainage.
5. Providea suitable air breakbetweenthe flood rimof
thefloor drain and outletofcondensate drain. 1" is
ideal.
6. Preventcondensatedrains fromfreezing:
a. Donot install condensate drains in contact with
non-insulatedsuction lines. Suction linesshouldbe
insulatedwith a nonabsorbent insulation material
suchasArmstrong’sArmaflex.
b. Wherecondensatedrains arelocated in dead air
spaces(betweenrefrigerators orbetweena
refrigerator and a wall),providemeansto prevent
freezing.Thewater seal should be insulated to
preventcondensation.

Refrigeration
REFRIGERANTTYPE
The standard refrigerant will be R-22 unless otherwise
specified on the customer order. Check the serial plate
on the case for information.
PIPING
The refrigerant line outlets are located under the case.
Locate first the electrical box,the outlets are then on the
same side of the case but at the opposite end. Insulate
suction lines to prevent condensation drippage.
REFRIGERATION LINES
LIQUID SUCTION
3/8" O.D. 5/8" O.D.
NOTE: The standard coil is piped at 5/8" (suction); however,
the store tie-in may vary depending on the number of
coils and the draw the case has. Depending on the case
setup, the connecting point in the store may be
5/8", 7/8", or 11/8". Refer to the particular case you are
hooking up.
Refrigerant lines should be sized as shown on the refrig-
eration legend furnished by the store.
Install P-traps (oil traps) at the base of all suction line ver-
tical risers.
Pressure drop can rob the system of capacity.To keep the
pressure drop to a minimum,keep refrigerant line run as
short as possible,using the minimum number of elbows.
Where elbows are required,use long radius elbows only.
CONTROL SETTINGS
See the “Case Specs” section of this guidebook for the
appropriatesettings foryourmerchandiser.Maintain these
parameters to achieve near constant product tempera-
tures.Producttemperatureshould be measuredfirstthing
in the morning, after having been refrigerated overnight.
For all multiplexing, defrost should be time terminated.
Loadmaster valves are not recommended.Defrost times
should be as follows: OFF CYCLE - One time daily for
110minutes.Thenumberof defrostsper dayshould never
change.The duration of the defrost cycle may be adjusted
to meet conditions present at your location.

STOCKING
Impropertemperatureandlighting willcause seriousprod-
uct loss. Discoloration, dehydration and spoilage can be
controlled with proper use of the equipmentandhandling
of product.Product temperature should always be main-
tained at a constant and proper temperature.This means
that from the time the product is received,through stor-
age,preparation and display,the temperature of the prod-
uct must be controlled to maximize life of the product.
Hussmann cases were not designed to“heat up” or“cool
down” product—but rather to maintain an item’s proper
temperature for maximum shelf life.To achieve the pro-
tection required always:
1. Minimizeprocessingtime to avoiddamaging tem-
peraturerisetothe product.Productshould be at
proper temperature.
2. Keeptheair in and aroundthe case area freeof
foreigngasses and fumes or foodwill rapidlydete-
riorate.
3. Maintainthe display merchandisers temperature
controls as outlinedin the refrigeratorsection of
thismanual.
4. Donot place anyproductinto these refrigerators
untilall controlshavebeen adjusted and theyare
operatingat the propertemperature.Allow mer-
chandiserto operate a minimumof 6 hours before
stockingwith anyproduct.
5. Whenstocking,neverallowthe productto extend
beyondthe recommendedload limit. Air dis-
charge and return air flue must be unob-
structed at all times to provide proper refrig-
eration.
6. Thereareventslocated atthe base of the front of
theglass,just abovethe frontrail.Theseventssupply
acontinuous,gentle flowof air acrossthe frontglass
whichinhibits condensation. Do not place any
signs or other restrictive objects on the front
of the refrigerator that will block these vents.
7. Keeptheservice doors closed(when applicable).
Refrigerationperformance will beseriouslyaffected
ifleft open for aprolonged periodoftime.
8. Avoidtheuseof supplemental flood orspotlighting.
Displaylight intensity has been designedformaxi-
mum visibility and productlifeat the factory.The use
ofhigher output fluorescentlamps (H.O.andV.H.O.),
willshorten the shelflifeof the product.
9. Inthe Deli,Meat and Fish cases,completelycover
theproducteach night with a clean dampclothor
butcherpaper (never useplastic,as it does notallow
for propercirculation).Makesurethe clothorpaper
isin directcontact with the product.
10.Turnand rotatethe meat fairlyoften.The blood
whichgivesthepink color worksits waydownward
withtime.
11.Cold coils removeheat andmoisturefrom the case
anddeposit this as frostonto thecoil.Thus,a
defrost is required.Our humidity system induces
moistureintothecase and helps slowdown the

IGSS-ESS/ESSS-0303
10
dehydrationprocess.The only othermoisture
within the case is thatin the product itself. A single
levelof meat will dry out fasterthan a fullyloaded
caseof 3–4 levels of meat.
IMPORTANT STEPS
1. Donot set temperaturetoo cold,as thiscauses
product dehydration.ProductTemperature:
33°–35°!
Setthermostat to cut in at 28° discharge air.Meat
holdingbox:32°.Meatpreproom:55°.Meat bloom
box:36°.
Processthemeat to enter case at 40° or below.
Productdeteriorationis very rapid above 40°.
2. Temperaturecontrolshould be bymeans of aT-Stat
andSuction Stop Solenoid at each case.Do not use
EPRvalves,LiquidLine Solenoids or electronic
controldevicesofanykind,asthese allowtempera-
tureswingscausing dehydration and excessive
energy consumption.
3. Productshouldbe workedand rotatedon a regular
basis,not to exceed a4-hour period.
4. Atnight,turn off case lights and coverthe product
witha damp (not wet)cloth similar to cheese cloth
(etc.).Thisshould be washed out in the morning and
kept in awalk-inboxduring the day—sothat it is
cooland moist when coveringthe product.
5. Dischargeair temperatureshould be approximately
26°F,with between150-200 FPM air velocity.Donot
displayproductdirectlywithinthe air discharge.
6. CleanHumidity system a minimumof every 90 days
forpropersystem operation.
CASE CLEANING
Long life and satisfactory performance of any equipment
aredependentupon the caregivento it.Toinsurelong life,
proper sanitation and minimum maintenance costs, the
refrigerator shouldbethoroughlycleanedfrequently.SHUT
OFF FAN DURING CLEANING PROCESS.It can be un-
plugged within the case,or shut off case at the source.The
interior bottom may be cleaned with any domestic soap
or detergent based cleaners. Sanitizing solutions will not
harmthe interior bottom,however,these solutions should
always be usedaccordingto the manufacturer’sdirections.
Itis essentialto establish andregulatecleaningprocedures.
This will minimize bacteria causing discoloration which
leads to degraded product appearance and signifigantly
shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A
sanitizing solution must be included with each cleaning pro-
cess to eliminate this bacteria.
1. Scrubthoroughly,cleaningall surfaces,with soapand
hotwater.
2. Rinsewith hot water,but do not flood.
3. Applythe sanitizing solution accordingtothe
manufacturer’sdirections.
4. Rinsethoroughly.
5. Drycompletely beforeresumingoperation.
CLEANING GLASS & MIRRORS
Only use a soft cloth and mild glass cleaner for cleaning
any glass or mirrored components.Be sure to rinse and/
or dry completely.
Never use hot water on cold glass surfaces! It
may shatter and cause serious injury! Allow glass
surfaces to warm first.
CLEANING PRECAUTIONS
WHEN CLEANING:
• DO NOT USE HIGH PRESSURE WATER HOSES
• DO NOT INTRODUCE WATER FASTER THAN WASTE OUTLET CAN DRAIN
• NEVER ON A SELF CONTAINED UNIT WITH AN EVAPORATOR FAN
• NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL
BASE (these will dissolve the butyl sealants) or an AMMONIA BASE
(this will corrode the copper componets of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
• DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY
• DO NOT USE ABRASIVES OR STEEL WOOL SCOURING PADS
(these will mar the finish)
PLEXIGLASS & ACRYLIC CARE
CLEANING
Clean with plenty of nonabrasive soap (or detergent) and
luke warm water,using the bare hand to feel and dislodge
any caked-on dirt.A soft,grit-free cloth,sponge or cham-
ois may be used,but only as a means of carrying the water
to the plastic. Dry with a clean damp chamois or clean
soft cloth such as cotton flannel. Hard, rough cloths or
paper towels will scratch the acrylic and should not be
used.
WAXING
If after removing dirt and grease,the acrylic can be waxed
with a good grade commercial wax.This will improve the
appearanceof thesurface byfillinginmost minorscratches.
Wax should be applied in a thin even coat and brought to
a high polish by rubbing lightly with a dry clean soft cloth,
such as a cotton flannel. Excessive rubbing may cause
scratching and/or buildup an electrostatic charge which

Rev.0303
11
attracts dust and dirt to the surface.Blotting with a clean
damp cloth is recommended to remove charge.
ANTISTATIC COATINGS
For acrylic used indoors, antistatic coatings successfully
prevent the accumulation of an electrostatic charge for
periods of several months—if the surface is not washed
or wiped down with a wet cloth.Between applications of
the antistatic coatings,the parts need only be dusted with
a soft clean cloth to maintain a good appearance. In use,
liquid antistatic coatings should be applied in a very thin
even coat.If beads appear as it is applied,the coat is too

PARTS LIST
•1"Plastic rod3/16" diameter
•AcrylicSolventCement (IPS weldon#16,#40 or
comparable)
•Maskingtape & duct tape (notsupplied)
INSTRUCTIONS
Note: Cases must be leveled and set prior to joining
plexiglass.Cases were prejoined,leveled and set
at the factory to assure proper fit at the installa-
tion.
Step 1 Prepare front plexiglass for cement applica-
tion by placing masking tape,a maximum 1/16
of an inch from the seam,on both sides front
and back. Tape is to protect plexiglass from
cement spill over. Scarring will occur if cement
touches clear plexiglass.
Step 2 Sand edges with 60-80 grit paper.Parts must
fit well with no visual gap.Keep plexiglass
clean and clear of dust.
Step 3 Remove protective mask from plexiglass.
Separate front plexiglass pieces enough to
apply a bead of #16 cement within one edge
inside of seam and plastic rod area. IfWeldon
#40 was supplied,refer to the instructions
below.
Step 4 Realign front plexiglass and push together
gently allowing cement to wet both surfaces.
Insert the plastic rod until flush with top of
plexiglass.
Step 5 Clamp firmly and apply tape (2" duct tape
recommended) across face of seam to secure
plexiglass from shifting while cement dries.
Allow 24 hours for glue to cure completely,
however joint will be strong enough to work
on after 2 hours.
INSTRUCTIONS FOR #40WELD-ON CEMENT
INSTRUCTIONS:
Step 1 Bring components "A" and "B" to room
temperature.
Step 2 Add component "A" to component "B".Items
have been pre-measured at the factory.
Step 3 Stir mixture slowly and evenly to prevent air
bubbles.Mix for 1-3 minutes.
Step 4 Apply cement to one or both surfaces with
applicator.Assemble immediately!
Step 5 Apply just enough pressure to remove air
bubbles.Do not squeeze joint so hard as to
force cement out of the joint – a dry joint
may result.
Step 4 Allow to dry approximately 4 hours (at 70°).
More time may be required at lower tempera-
tures.

Maintenance
ELECTRICAL PRECAUTIONS
BEFORE SERVICING – Always disconnect
electrical power at the main disconnect when
servicing or replacing any electrical component
This includes (but not limited to) Fans, Heaters,
Thermostats, and Lights.
REPLACING FLUORESCENT LAMPS
Fluorescent lamps are furnished with moisture resistant
lamp holders,shields and end caps.Whenever a florescent
lamp is replaced, be certain to reinstall the lamp shield
and end caps over the lamp.The lamps supplied are single
slim-line or bi-pin type with or without starters.
T- 5 REPLACEMENT
After replacing theT-5 bulbs, be sure to turn the light(s)
off then on again.
EVAPORATOR FANS
The evaporator fans are located at the center front of
these merchandisers directly beneath the display pans.
Shouldfansor blades need servicing,always replacefan blades
with the raised embossed side of the blade TOWARD THE
MOTOR.
COPPER COILS
The copper coils used in Hussmann merchandisers may
be repaired in the field.Materials are available from local
refrigeration wholesalers.
Hussmann recommends using #15 Sil-Fos for repairs.
TIPS & TROUBLESHOOTING

APPENDIX A. – Temperature Guidlines
The refrigerators should be operated according to the manufacturer’s
published engineering specifications for entering air temperatures for
specific equipment applications. Table 1 shows the typical temperature
of the air entering the food zone one hour before the start of defrost
and one hour after defrost for various categories of refrigerators.
Refer to Appendix C for Field Evaluation Guidelines.

APPENDIX B. – Application Recommendations
1.0 Temperature performance is critical for controlling bacteria
growth. Therefore, the following recommendations are included in
the standard. They are based on confirmed field experience over
many years.
1.1 The installer is responsible for following the installation instruc-
tions and recommendations provided by the manufacturer for the
installation of each individual type refrigerator.
1.2 Refrigeration piping should be sized according to the equipment
manufacturer’s recommendations and installed in accordance with
normal refrigeration practices. Refrigeration piping should be
insulated according to the manufacturer’s recommendations.
1.3 A clogged waste outlet blocks refrigeration. The installer is
responsible for the proper installation of the system which
dispenses condensate waste through an air gap into the building
indirect waste system.
1.4 The installer should perform a complete start-up evaluation prior to
the loading of food into the refrigerator, which includes such items as:
a)Initial temperature performance, Coils should be properly fed with
a refrigerant according to manufacturer’s recommendations.
b)Observation of outside influences such as drafts, radiant
heating from the ceiling and from lamps. Such influence should
be properly corrected or compensated for.
c) At the same time, checks should be made of the store dry-
bulb and wet-bulb temperatures to ascertain that they are
within the limits prescribed by the manufacturer.
d)Complete start-up procedures should include checking through
a defrost to make certain of its adequate frequency and length
without substantially exceeding the actual needs. This should
include checking the electrical or refrigerant circuits to make
sure that defrosts are correctly programmed for all the
refrigerators connected to each refrigeration system.
e) Recording instruments should be used to check performance.
APPENDIX C. – Field Recommendations
Recommendations for field evaluating the performance of retail
food refrigerators
1.0 The most consistent indicator of display refrigerator performance
is temperature of the air entering the product zone (see
Appendix A). In practical use, the precise determination of return
air temperature is extremely difficult. Readings of return air
temperatures will be variable and results will be inconsistent. The
product temperature alone is not an indicator of refrigerator
performance.
NOTE: Public Health will use the temperature of the product in
determining if the refrigerator will be allowed to display potentially
hazardous food. For the purpose of this evaluation, product
temperature above the FDA Food Code 1993 temperature for
potentially hazardous food will be the first indication that an
evaluation should be performed. It is expected that all refrigerators
willkeepfood atthe FDA FoodCode 1993temperaturefor potentially
hazardous food.
1.1 The following recommendations are made for the purpose of
arriving at easily taken and understood data which, coupled with
other observations, may be used to determined whether a display
refrigerator is working as intended:
a) INSTRUMENT – A stainless steel stem-type thermometer is
recommended and it should have a dial a minimum of 1 inch
internal diameter. A test thermometer scaled only in Celsius or
dually scaled in Celsius and Fahrenheit shall be accurate to
1°C (1.8°F). Temperature measuring devices that are scaled
