Installation
store floor.
B. When wedges are involved in a lineup, set them
first.
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-
tive humidity.DO NOT allow air conditioning,electric fans,
ovens, open doors or windows (etc.) to create air cur-
rents around the merchandiser, as this will impair its cor-
rect operation.
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. Check level of floor where cases are to be set.
Determine the highest point of the floor;cases will
be set off this point.
2. Set first case,and adjust legs over the highest part of
the floor so that case is level.Prevent damage – case
must be raised under leg or by use of 2x6 or 2x4 leg
brace.Remove side and back leg braces after case is
set.
3. Set second case as close as possible to the first case,
and level case to the first using the instructions in
step one.
4. Apply masking tape 1/8" in from end of case on
inside and outside rear mullion on both cases to be
joined.
DO NOT place Self Contained versions
of this case, having the electric evapo-
rator pan, underneath or adjacent to
any flam m able structure or structure
housing flam m able m erchandise!
UNCRATING THE 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!
EXTERIO R LOADING
These models have not been structurally designed to sup-
port excessive external loading. Do not walk on their
tops; This could cause serious personal injury and dam-
age to the fixture.
5. Apply liberal bead of case joint sealant (butyl) to
dotted area shown in (Fig.2,#1) of first case. Apply
heavy amount to cover entire shaded area.
DO NOT USE PERMAGUM!
6. Slide second case up to first case snugly.Then level
second case to the first case so the front bumper
and top fascia are even.
SETTING AND JO INING
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.
7. To compress silicone at joint,use two Jurgenson
wood clamps.Make sure case is level from front to
back and side to side on inside bulkheads at joint.
8. Bolt tops together behind llight, and close camlocks
usiong a 5/16" allen wrench.Camlocks are located in
the rear of the case below air discharge and be-
tween the front legs.
Attention Installer!
Proper case joint sealing is extremely
important to prevent water leaks!
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.
LEVELING
IMPO RTANT! It is im perative that cases be
leveled from front to back and side to side prior
to joining. A level case is necessary to insure
proper operation, water drainage, glass align-
m ent, and operation of the hinges supporting
the glass. Leveling the case correctly will solve
m ost hinge operation problem s.
Do not use cam locks to pull cases together.
ENDS
Bolt the end(s) onto the case using the bolts provided in
the pre-drilled holes on the side(s) of the case.

ideal.
W ASTE O UTLET AND P-TRAP
The waste outlet is located in the center,8" from the front
of the case.
A 7/8" 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.
6. Prevent condensate drains from freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such asArmstrong’sArmaflex.
NOTE: PVC-DWV solvent cement is recommended.
Follow Hussmann’s instructions.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a
refrigerator and a wall),provide means to prevent
freezing.The water seal should be insulated to
prevent condensation.
INSTALLING CO NDENSATE DRAIN
Poorly or improperly installed condensate drains can se-
riously interfere with the operation of this refrigerator,
and result in costly maintenance and product losses.Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains,the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance.Store plumb-
ing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section.Never use two water seals in series in any
one line.Double P-traps in series will cause a lock
and prevent draining.
RED (SELF CO NTAINED)
The waste outlet and P-trap are the same as the remote
except the case condensate drains to a pump assembly
mounted to the top of the case into the top of the water
evap assembly. Hot air from the condenser is forced
through the water evap assembly, evaporating the water.
Any overflow from the water evap assembly is directed
back to the pump assembly. It is critical that the case
be level to keep the water evap assem bly from
overflowing!! The metal cover over the top of the con-
densing unit must be in place to force the hot condenser
air through the water evap assembly.
The condensate pump can be accessed through the front
of the closeoff panel.
3. Always provide as much down hill slope (“fall”) as
possible;1/8" per foot is the preferred minimum.
PVC pipe,when used,must be supported to main-
tain the 1/8" pitch and to prevent warping.
4. Avoid long runs of condensate drains.Long runs
make it impossible to provide the“fall” necessary for
good drainage.
5. Provide a suitable air break between the flood rim of

THERMO STATIC EXPANSIO N VALVE LO CATIO N
AnAlco balanced port expansion valve model is furnished
as standard equipment,unless otherwise specified by cus-
tomer.There is one expansion valve located on the right
side of each evaporation coil under the bottom deck pans.
The refrigerant line outlets are located under the fixture
at the left hand end when viewed from the back. Insulate
the suction lines to prevent condensation leakage.

Expansion valves must be adjusted to fully feed the evapo-
rator. Before attempting any adjustments, make sure the
evaporator is either clear or very lightly covered with frost,
and that the fixture is within 10°F of its expected operat-
ing temperature.
MEASURING THE O PERATING SUPERHEAT
1. Determine the suction pressure with an accurate
pressure gauge at the evaporator outlet.
2. From a refrigerant pressure temperature chart,
determine the saturation temperature at the
observed suction pressure.
3. Measure the temperature of the suction gas at the
thermostatic remote bulb location.
4. Subtract the saturation temperature obtained in step
No.2 from the temperature measured in step No.3.
3. The difference is superheat.
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
7
5/8", /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.
CO NTRO L SETTINGS
5. Set the superheat for 5°F - 7°F.
See the “Case Specs” section of this guidebook for the
appropriate settings for your merchandiser.Maintain these
parameters to achieve near constant product tempera-
tures.Product temperature should be measured first thing
in the morning, after having been refrigerated overnight.
For all multiplexing, defrost should be time terminated.
Defrost times should be as follows: OFF CYCLE - One
time daily for 110 minutes. The number of defrosts per
day should never change.The duration of the defrost cycle
may be adjusted to meet conditions present at your loca-
tion.
FAN SPEED CO NTRO L
Located in the electrical raceway on the lower right end
is a fan speed control.This control is set at the factory for
maximum. To adjust, turn the knob clockwise to obtain
approximately 50 FPM air speed. This may vary due to
store ambient conditions, especially the relative humidity.
With low humidity, slow the fan.With high humidity con-
ditions, set the control for maximum. Each case has its
own control and allows independant settings in case line-
ups.
NOTE: Slow air picks up more humidity from coil and ice.
ACCESS TO TX VALVES & DRAIN LINES
MECHANICAL - Remove product from the case. Remove
product racks (if applicable).Remove refrigeration and drain
access panels (labeled).TX valve (mechanical only) and drain
are located under each access panel at end of the case.
ELECTRONIC -The Electronic Expansion valve master and
slave cylinder(s) are located within the electrical access
panel(s).
Condenser Ventilation
Be sure to supply adequate ventilation for the condenser
in Self Contained units.Allow 150 square inches for units
up to 1 1/2 h.p., and 200 for condensr units over 2 h.p.

CASE CLEANING
STO CKING
Long life and satisfactory performance of any equipment
are dependent upon the care given to it.To insure long life,
proper sanitation and minimum maintenance costs, the
refrigerator should be thoroughly cleaned frequently.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
harm the interior bottom,however,these solutions should
always be used according to Hussmann’s directions. It is
essential to establish and regulate cleaning procedures.This
will minimize bacteria causing discoloration which leads
to degraded product appearance and signifigantly short-
ening 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. Scrub thoroughly,cleaning all surfaces,with soap and
hot water.
2. Rinse with hot water,but do not flood.
3. Apply the sanitizing solution according to Hussmann’s
directions.
Improper temperature and lighting will cause serious prod-
uct loss. Discoloration, dehydration and spoilage can be
controlled with proper use of 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. Minimize processing time to avoid damaging tem-
perature rise to the product.Product should be at
proper temperature.
2. Keep the air in and around the case area free of
foreign gasses and fumes or food will rapidly dete-
riorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of
this manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they are
operating at the proper temperature.Allow mer-
chandiser to operate a minimum of 6 hours before
stocking with any product.
5. When stocking,never allow the product to extend
beyond the recommended load limit. Air dis-
charge and return air flue m ust be unob-
structed at all tim es to provide proper refrig-
eration.
4. Rinse thoroughly.
5. Dry completely before resuming operation.
CLEANING GLASS & MIRRO RS
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
m ay shatter and cause serious injury! Allow glass
surfaces to warm first.
6. Avoid the use of supplemental flood or spot lighting.
Display light intensity has been designed for maxi-
mum visibility and product life at the factory.The use
of higher output fluorescent lamps (H.O.andV.H.O.),
will shorten the shelf life of the product.
IMPO RTANT STEPS
C LEAN IN G PREC AU T IO N S
1. Do not set temperature too cold,as this causes
product dehydration. Refer to the Case Specifi-
cations section of this book for proper set-
tings.
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
2. Temperature control should be by means of aT-Stat
and Suction Stop Solenoid at each case.Do not use
EPR valves,Liquid Line Solenoids or electronic
control devices of any kind,as these allow tempera-
ture swings causing dehydration and excessive
energy consumption.
• 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)

ANTISTATIC COATINGS
PLEXIGLASS & ACRYLIC CARE
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
thick and the excess should be removed with another cloth.
Allow the coating to dry, then bring to a high gloss with a
soft cloth.
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.
W AXING
If after removing dirt and grease,the acrylic can be waxed
with a good grade commercial wax.This will improve the
appearance of the surface by filling in most minor scratches.
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
attracts dust and dirt to the surface. Blotting with a clean
damp cloth is recommended to remove charge.
Maintenance

insulated according to Hussmann’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 Hussmann.

1.0 The most consistent indicator of display refrigerator performance
is temperature of the air entering the product zone (see

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
will keep food at the FDA Food Code 1993 temperature for potentially
hazardous food.

APPENDIX B. – Application Recom m endations
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 Hussmann for the
installation of each individual type refrigerator.
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
1.2 Refrigeration piping should be sized according to the equipment
manufacturer’s recommendations and installed in accordance with

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:
manufacturer? Is the refrigerator charged with the proper
refrigerant and lubricant? Does the system use the recommended
compressor?
APPENDIX D. – Recom m endations to user
1.0 Hussmann should provide instructions and recommendations for
proper periodic cleaning. The user will be responsible for such
cleaning, including the cleaning of low temperature equipment 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. 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?
1.2 Load levels as defined by Hussmann must be observed.
1.3 The best preservation is achieved by following these rules:
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 Hussmann?
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.?
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.
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.
19. Is there a shortage of refrigerant?
i) Make sure that all refrigeration equipment is installed and adjusted
in strict accordance with Hussmann’s recommendations.
j) See that all storage and refrigeration equipment is kept in proper
working order by routine maintenance.
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
