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.DONOTallowairconditioning,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 havenot been structurallydesignedto sup-
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
IMPORTANT! IT IS IMPERATIVE THAT
CASES BE LEVELED FROM FRONT TO
BACK AND SIDETO SIDE PRIORTO JOIN-
ING.A LEVEL CASE IS NECESSARYTO IN-
SURE PROPER OPERATION, WATER
DRAINAGE, GLASS ALIGNMENT,AND OP-
ERATION OF THE HINGES SUPPORTING
THE GLASS. LEVELING THE CASE COR-
RECTLYWILL SOLVE MOST HINGEOPERA-
TION PROBLEMS.
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 floorwherecases areto beset.
Determinethe highest point of the floor;caseswill
beset off this point.
2. Setfirst case,andadjust legsoverthehighest part of
thefloor so that case is level.Preventdamage – case
must be raised under legor byuse of2x6 or 2x4leg
brace.Removesideand back legbraces after case is
set.
3. Setsecond caseas close as possible tothe firstcase,
andlevelcase to thefirst using the instructions in
stepone.
4. Applymasking tape 1/8"in fromend of caseon

joined.
5. Applyliberal bead of case joint sealant (butyl)to
dotted area shownin (Fig.2,#1) of first case. Apply
heavyamount to coverentireshadedarea.
DO NOT USE PERMAGUM!
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.
6. Slidesecond case up to first case snugly.Thenlevel
secondcase to the first case so glass front,bumper
andtop areflush.
7. Applybead of silicone to side of eitherhalf of case(if
caseis built in twopieces). Alsoapplysilicone to
seambetweenoverheadlight tubes.
8. Slidesecond half up to first case snugly.To compress
siliconeat joint,usetwoJurgensonwoodclamps to

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.
ACCESS PANELS
All electrical and drain access panels are clearly labeled
on the deck of the produce stand.The access for con-
densing units (in the self contained units) is located on the
side of the stand, at the end. Ends of stand are fitted for
removal,if condensing unit has to be taken out.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se-
riously interfere with the operation of this refrigerator,
andresultincostlymaintenanceand productlosses.Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Neveruse pipefor condensate drains smallerthan
thenominal diameter of the pipe or P-trapsupplied
withthe case.
2. Whenconnecting condensate drains,theP-trap
mustbe used as part of thecondensate drain to
preventair leakage orinsect entrance.Storeplumb-
ingsystem floor drains should be at least 14"off the
centerof the case to allowuse ofthe P-trappipe
section.Neveruse twowater seals inseries in any
oneline.DoubleP-traps in series will cause a lock
andpreventdraining.
3. Always provideas muchdown hill slope (“fall”)as
possible;1/8"per footis the preferredminimum.
PVCpipe,when used,must besupportedto main-
tainthe 1/8" pitch and to preventwarping.
4. Avoidlong runs of condensate drains.Long runs
makeit impossible to providethe“fall” necessaryfor
gooddrainage.
5. Providea suitableair breakbetweenthe flood rimof
thefloor drainand outlet of condensate drain.1" is
ideal.
6. Preventcondensate drains fromfreezing:
a. Donot install condensatedrains in contact with
non-insulatedsuction lines.Suction lines should be
insulatedwith a nonabsorbent insulation material
suchasArmstrong’sArmaflex.
b. Wherecondensate drains are located in deadair
spaces(betweenrefrigeratorsor betweena
refrigerator and awall),provide means to prevent
freezing.Thewater sealshould be insulated to
preventcondensation.
HOSE REEL
If an optional hose reel is ordered, it will be installed at the
factory. The water supply valve is located next to the access
panel. Connect the water supply to the valve.
SPRAY HOSE
If an optional quick-disconnect spray hose is ordered, a
pressure regulating valve should be installed. If the water
pressure exceeds 45 PSI, the valve should be set for 30 to 35
PSI outlet pressure.

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.
ACCESS PANELS
All electrical and drain access panels are clearly labeled
on the deck of the produce stand.The access for con-
densing units (in the self contained units) is located on the
side of the stand, at the end. Ends of stand are fitted for
removal,if condensing unit has to be taken out.
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
appropriatesettingsforyourmerchandiser.Maintain these
parameters to achieve near constant product tempera-
tures.Producttemperatureshould bemeasuredfirstthing
in the morning, after having been refrigerated overnight.
For all multiplexing, defrost should be time terminated.
Loadmaster valves are not recommended.Defrost times
should as directed in the Case Specifications section of
this guide.The number of defrosts per day should never
change.The duration of the defrost cycle may be adjusted
to meet conditions present at your location.

ELECTRONIC EXPANSIONVALVE (OPTIONAL)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and con-
trollermanufacturersinformationsheet. Sensors forelec-
tronic expansion valves will be installed on the coil inlet,
coil outlet, and in the discharge air. (Some supermarkets
require a 4th sensor in the return air). Case controllers
will be located in the electrical raceway or under the case
THERMOSTATIC EXPANSIONVALVE LOCATION
This device is located on the same side as the refrigera-
tion stub. A balanced port expansion valve model is fur-
nished as standard equipment,unless otherwise specified
by customer.
EXPANSIONVALVE ADJUSTMENT
Expansion valves must be adjusted to fully feed the evapo-
rator. Before attempting any adjustments,make sure the
evaporatoriseitherclear orverylightlycoveredwith frost,
and that the fixture is within 10°F of its expected operat-

STOCKING
Impropertemperatureandlighting willcauseserious prod-
uct loss. Discoloration, dehydration and spoilage can be
controlled with properuseof the equipment and handling
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 toavoiddamagingtem-
peraturerise to theproduct.Productshould beat
proper temperature.
2. Keep theair in andaroundthe case areafreeof
foreigngasses and fumes or foodwill rapidlydete-
riorate.
3. Maintainthe displaymerchandiserstemperature
controlsas outlined inthe refrigeratorsectionof
thismanual.
4. Donot place anyproductinto theserefrigerators
untilall controlshavebeen adjustedand theyare
operatingat the propertemperature.Allow mer-
chandiserto operate a minimumof 6hours before
stockingwith anyproduct.
5. Whenstocking,never allow theproductto 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 frontof
theglass,just abovethe frontrail.Theseventssupply
acontinuous,gentleflow of air acrossthe front glass
whichinhibits condensation. Do not place any
signs or other restrictive objects on the front
of the refrigerator that will block these vents.
7. Avoidthe use of supplemental floodor spotlighting.
Displaylight intensity has beendesigned formaxi-
mumvisibilityand productlifeat the factory.Theuse
ofhigher outputfluorescentlamps (H.O.andV.H.O.),
willshorten the shelf lifeof theproduct.
8. Coldcoils removeheat and moisturefrom the case
anddeposit this asfrostontothe coil.Thus,a
defrost is required.Theonly othermoisturewithin
the case is that inthe productitself. A single level of
meatwill dry out faster thana fullyloaded case of3–
4levelsof meat.
IMPORTANT STEPS
1. Donot set temperaturetoo cold,asthis causes
product dehydration.See Case Specs for Proper
Temperature:Settings.
CASE CLEANING
Long life and satisfactory performance of any equipment
aredependent upon thecaregivento it.To insurelong life,
proper sanitation and minimum maintenance costs, the
refrigerator should be thoroughlycleanedfrequently.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 interiorbottom,however,thesesolutions should
always be used accordingtothe manufacturer’s directions.
Itisessential toestablish and regulatecleaning procedures.
This will minimize bacteria causing discoloration which
leads to degraded product appearance and significantly
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,cleaning allsurfaces,with soapand
hotwater.
2. Rinsewith hot water,but donot flood.
3. Applythe sanitizing solution accordingto the
manufacturer’s directions.
4. Rinsethoroughly.
5. Dry completelybeforeresumingoperation.
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 components 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)

APPENDIX A. – Temperature Guidelines
Refrigerated
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 Evalua-
tion Guidelines.

APPENDIX B. – Application
Recommendations
Refrigerated
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 -
Refrigerated
Recommendations for field evaluating the performance of retail
food refrigerators and hot cases
1.0 The most consistent indicator of display refrigerator performance
is temperature of the air entering the product zone (Refrigerated
see Diagram 1, 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 refrigera-
tors will keep food at the FDA Food Code 1993 temperature for
Appendices

IGIP-DBP, DBRP 01,03-0210

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 only in
Fahrenheit shall be accurate to 2°F. The thermometer should be
checked for proper calibration. (It should read 32°F when the
stem is immersed in an ice water bath).
b) LOCATION – The probe or sensing element of the thermometer
should be located in the airstream where the air first enters the
display or storage area, and not more than 1 inch away from the
surface and in the center of the discharge opening.
c) READING – It should first be determined that the refrigerator is
refrigerating and has operated at least one hour since the end of
the last defrost period. The thermometer reading should be made
only after it has been allowed to stabilize, i.e., maintain a
constant reading.
d) OTHER OBSERVATIONS – Other observations should be made which
may indicate operating problems, such as unsatisfactory product,
feel/appearance.
e) CONCLUSIONS – In the absence of any apparent undesirable
conditions, the refrigerator should be judged to be operating
properly. If it is determined that such condition is undesirable,
i.e., the product is above proper temperature, checks should be
made for the following:
1. Has the refrigerator been loaded with warm product?
2. Is the product loaded beyond the “Safe Load Line” markers?
3. Are the return air ducts blocked?
4. Are the entering air ducts blocked?
5. Is a dumped display causing turbulent air flow and mixing with
room air?
6. Are spotlights or other high intensity lighting directed onto the
product?
7. Are there unusual draft conditions (from heating /air-conditioning
ducts, open doors, etc.)?
8. Is there exposure to direct sunlight?
8. Are display signs blocking or diverting airflow?
9. Are the coils of the refrigerator iced up?
11. Is the store ambient over 75°F, 55% RH as set forth in ASHRAE
Standard 72 and ASHRAE Standard 117?
12. Are the shelf positions, number, and size other than recom-
mended by the manufacturer?
13. Is there an improper application or control system?
14. Is the evaporator fan motor/blade inoperative?
15. Is the defrost time excessive?
16. Is the defrost termination, thermostat (if used) set too high?
17. Are the refrigerant controls incorrectly adjusted?
18. Is the air entering the condenser above design conditions? Are
the condenser fins clear of dirt, dust, etc.?
19. Is there a shortage of refrigerant?
20. Has the equipment been modified to use replacements for CFC-12,
CFC-502 or other refrigerant? If so, have the modifications been
made in accordance with the recommendations of the equipment
manufacturer? Is the refrigerator charged with the proper
refrigerant and lubricant? Does the system use the recommended
compressor?
APPENDIX D. – Recommendations to user -
Refrigerated
1.0 The manufacturer should provide instructions and recommenda-
tions for proper periodic cleaning. The user will be responsible for
such cleaning, including the cleaning of low temperature equip-
ment within the compartment and the cooling coil area(s).
Cleaning practices, particularly with respect to proper refrigerator
unloading and warm-up, must be in accordance with applicable
recommendations.
1.1 Cleaning of non frozen food equipment should include a weekly
cleaning of the food compartment as a minimum to prevent
bacteria growth from accumulating. Actual use and products may
dictate more frequent cleaning. Circumstances of use and
equipment design must also dictate the frequency of cleaning the
display areas. Weekly washing down of the storage compartment
is also recommended, especially for equipment subject to drippage
of milk or other liquids, or the collection of vegetable, meat,
crumbs, etc. or other debris or litter. Daily cleaning of the
external areas surrounding the storage or display compartments
with detergent and water will keep the equipment presentable
and prevent grime buildup.
1.2 Load levels as defined by the manufacturer must be observed.
1.3 The best preservation is achieved by following these rules:
a)Buy quality products.
b)Receive perishables from transit equipment at the ideal
temperature for the particular product.
c) Expedite perishables to the store’s storage equipment to avoid
unnecessary warm-up and prolonged temperature recovery. Food
store refrigerators are not food chillers nor can they reclaim
quality lost through previous mishandling.

Rev.0210
17
d)Care must be taken when cross merchandising products to
ensure that potentially hazardous vegetable products are not
placed in non refrigerated areas.
e) Display and storage equipment doors should be kept closed
during periods of inactivity.
f) Minimize the transfer time of perishables from storage to
display.
g)Keep meat under refrigeration in meat cutting and processing
area except for the few moments it is being handled in
processing. When a cut or tray of meat is not to be worked
on immediately, the procedure should call for returning it to
refrigeration.
h)Keep tools clean and sanitized. Since mechanical equipment is
used for fresh meat processing, all such equipment should be
cleaned at least daily and each time a different kind of meat
product comes in contact with the tool or equipment.
i) Make sure that all refrigeration equipment is installed and
adjusted in strict accordance with the manufacturer’s recom-
mendations.
j) See that all storage and refrigeration equipment is kept in
proper working order by routine maintenance.
