4. Installation
Setting and Joining
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%
relative humidity. DO NOT allow air conditioning, electric
fans, ovens, open doors or windows (etc.) to create air
currents around the merchandiser, as this will impair its
correct 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.
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!
Exterior Loading
These models have not been structurally designed to
support excessive external loading. Do not walk on
their tops; This could cause serious personal injury and
damage to the fixture.
GLASS BREAKAGE MAY OCCUR!
Retighten glass along clamshell after
leveling and first time case is brought
to full operating temperature!
Glass Adjustment
During shipment, the lubricant inside the cylinders may
have settled. This settling may cause excessive or un-
even tension on the glass - to the point of breakage. To
avoid any damage, please follow these three easy steps:
1. Slowly raise and lower each glass section 6 times to
a height of 6 inches.
2. Increase the height to 12 inches, and raise and
lower the glass 6 more times.
3. Finally raise the glass to its full extension, and lower.
These steps should release any settled lubricant within
the cylinders and prevent any stress on the front glass.
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 SIDE
TO SIDE PRIOR TO JOINING. A LEVEL CASE IS
NECESSARY TO INSURE PROPER OPERATION,
WATER DRAINAGE, PLEXIGLASS ALIGNMENT.
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. 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.
5. Apply liberal bead of case joint sealant (butyl) to
(dotted area shown in figure) first case. Apply heavy
amount to cover entire shaded area.
DO NOT USE PERMAGUM!
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.

6. Slide second case up to first case snugly. Then level
second case to the first case so glass front, bumper
and top are flush.

Installation (Cont'd)
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. Attach sections together viaa2boltslocatedinthe
base of the case. Secure the overhead structure by
bolting the bracket, located inside behind lights.
9. Apply bead of silicone to top of bulkheads and slip on
stainless steel bulkhead cap. Also apply silicone to
seam between overhead light tubes.
10. Use finger to smooth silicone as thin as possible at
masking tape on inside and outside of rear mullion
(apply additional silicone if necessary). Remove tape
applied on line #3.
Corner Wedges
Corner wedges are attached via front and rear camlocks.
Use a 7mm allen wrench to turn the locks. Do not over-
tighten! Join the top by using a joint bracket (included in
joint kit) with 3/8” bolts.
Joint Trim
After cases have been leveled and joined, and refrigera-
tion, electrical, and wasted piping work completed, install
the splashguards. Fasten along the top edge, or center,
with #10 X 3/3” sheet metal screws.
DO NOT SEAL JOINT TRIM TO FLOOR!

Bumper Installation Instructions
Step 3: Starting on one end: while
inserting the bumper, push it up against
the end cap to prevent the bumper from
shrinking after installation (when it gets
cold).
Step 4: As you insert the bumper
into the channel with one hand, pull the
bumper toward you with the other to open
the inside lips. Slowly apply pressure by
rolling the bumper into the track.

5. Plumbing
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. There are 3 drains in each fixture that can be
easily located.
1-1/2", 1" and 3/4" P-TRAPS and threaded adapters
are supplied with each fixture. The 3 P-TRAPS 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
seriously 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 installa-
tion:
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
plumbing 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.
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
maintain 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
the floor drain and outlet of condensate drain. 1" is
ideal.
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 non - absorbent
insulation material such as Armstrong's
Armaflex.
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.
6. Refrigeration
Refrigerant lines should be sized as shown on the refrig-
10
Refrigerant Type
The standard refrigerant will be R-404A 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
3/8” O.D.
Suction
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 particu-
lar case you are hooking up.
eration legend furnished by the store.
Install P-TRAPS (oil traps) at the base of all suction line
vertical risers.
Pressure drop can rob the system of capacity. To keep
thepressuredroptoaminimum,keeprefrigerantline
run as short as possible, using the minimum number
of elbows. Where elbows are required, use long radius
elbows only.
Control Settings
Maintain these parameters to achieve near constant
product temperatures. Product temperature should be
measured first thing in the morning, after having been re-
frigerated overnight. Defrost times should be as follows:
OFF CYCLE - The number of defrosts per day and the
duration of the defrost cycle may be adjusted to meet
conditions present at your location.

Refrigeration (Cont'd)
Access to TX Valves and Drain Lines
Mechanical - Remove product from end of case. Re-
move product racks. 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).
Electronic Expansion Valve (Optional)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and
controller manufacturers information sheet. Sensors for
electronic expansion valves will be installed on the coil
inlet, coil outlet, and in the discharge air. (Some super-
markets require a 4th sensor in the return air). Case
controllers will be located in the electrical raceway or
under the case. The front Self Service Evaporator has
an EPR valve installed to maintain a constant discharge
temperature. It is located in the front at the right side of
the case under the fan plenum near the TX valve.
Thermostatic Expansion Valve
Location
This device is located on the same side as the refrig-
eration stub. A Sporlan balanced port expansion valve
model is furnished as standard equipment, unless other-
wise specified by customer.
Expansion Valve Adjustment
Expansion valves must be adjusted to fully feed the
evaporator. 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 expect-
ed operating temperature.
Measuring the Operating 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. from the temperature measured in step No. 3.
The difference is superheat.
5. Set the superheat for 5°F - 7°F.
Evaporator Pressure Regulator
An Evaporator Pressure Regulator is installed in the front
of the self service section to maintain a constant discharge
temperature. It is located at the front right side of the case,
under the fan plenum near the TX Valve.
Service Case Temperature Control
Temperature control in the upper section of the R3 with
the Service Option is done by means of a thermostat and
suction solenoid valve. This controls both temperature
and humidity.
T-STAT Location
T-STATS are located within the electrical raceway. Refer
to diagram below.

Wiring Color Code
CASE MUST BE GROUNDED
NOTE: Refer to label affixed to case to determine
the actual configuration as checked in the “TYPE
INSTALLED” boxes.
Electrical Circuit Identification
Standard lighting for all refrigerated models will be full
length fluorescent lamps located within the case at the
top.
The switch controlling the lights, the plug provided for
digital scale, and the thermometer are located at the rear
of the case mullion.
The receptacle that is provided on the exterior back of
these models is intended for computerized scales with
afive amp maximum load, not for large motors or other
high wattage appliances. It should be wired to a dedi-
cated circuit.
7. Electrical
Electrical Service Receptacles (When
Applicable)
The receptacles located on the exterior of the merchan-
diser are intended for scales and lighted displays. They
are not intended nor suitable for large motors or other
external appliances.
DANGER
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.
15
Field Wiring and Serial Plate
Amperage
Field Wiring must be sized for component amperes print-
ed on the serial plate. Actual ampere draw may be less
than specified. Field wiring from the refrigeration control
panel to the merchandisers is required for refrigeration
thermostats. Case amperes are listed on the wiring dia-
gram, but always check the serial plate.
LED Driver Location
Drivers are located within the access panel that runs the
length of the rear of the case.

Stocking
Improper temperature and lighting will cause serious
product loss. Discoloration, dehydration and spoilage
can be controlled with proper use of the equipment and
handling of product. Product temperature should always
be maintained at a constant and 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 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
protection required always:
1. Minimize processing time to avoid damaging
temperature 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
deteriorate.
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
merchandiser 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 discharge
and return air flow must be unobstructed at all times
to provide proper refrigeration.
6. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
7. Avoid the use of supplemental flood or spot lighting.
Display light intensity has been designed for
maximum visibility and product life at the factory.
The use of higher output fluorescent lamps (H.O.
and V.H.O.), will shorten the shelf life of the product.
FOR PROMPT SERVICE
When Contacting the Factory regarding problems.
Be sure to have the Case MODEL and
SERIAL NUMBER Handy. This Information
is on a plate located on the case itself.
8. User Information
Cleaning Glass and Mirrors
16
Only use a soft cloth and mild glass cleaning for clean-
ing 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.

Non-glare Glass
Windex® or Glass Plus® are the only solutions recom-
mended to be used to clean the non-glare glass. The
damage to the glass from improper, caustic solutions is
irreparable.
In addition to cleaning the glass with the recommended
product, there are precautions that should be taken
when working and cleaning the inside of the case.
• When cleaning the inside of the cases, we recommend
that the glass be fully opened and covered to prevent to
prevent solutions from splashing onto the glass and ruin-
ing the coating on the inside.
Plexiglass and Acrylic Care
Improper cleaning not only accelerates the cleaning cy-
cle but also degrades the quality of this surface. Normal
daily buffing motions can generated static cling attracting
dust to the surface. Incorrect cleaning agents or cleaning
cloths can cause micro scratching of the surface, caus-
ing the plastic to haze over time.
Cleaning
Hussmann recommends using a clean damp chamois,
or a paper towel marketed as dust and abrasive free with
210® Plastic Cleaner and Polish available by calling
Sumner Labs at 1-800-542-8656. Hard, rough cloths or
paper towels will scratch the acrylic and should not be
used.
Antistatic Coatings
The 210® has proven to be very effective in not only
cleaning and polishing the Plexiglass surface, but also
providing antistatic and anti-fog capabilities. This product
also seals pores and provides a protective coating.
CLEANING PRECAUTIONS
When cleaning:
Do not use high pressure water hoses
Do not introduce water faster then waste outlet can drain
NEVER INTRODUCE WATER ON SELF CONTAINED UNIT
WITH AN EVPORATOR PAN
NEVER USE A CLEANING OR SANITIZING SOLUTION
THAT HAS AN OIL BASE (these will dissolve the butyl
sealants) or an AMMONA 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 A CHLORANITED CLAENER ON ANY
SURFACE
DO NOT USE ABRASIVES OR STEEL WOOL SCOURING
PADS (these will mar the finish)
CAUTION
User Information (Cont'd)
Evaporator Fans
17
The evaporator fans are located at the center front of
these merchandisers directly beneath the display pans.
Should fans or blades need servicing, always replace
fan 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 and Troubleshooting
Before calling for service, check the following:
1. Check electrical power supply to the equipment for
connection.
2. Check fixture loading. Overstocking case will affect
its proper operation.
3. If frost is collecting on fixture and/or product, check
that no outside doors or windows are open - allowing
moisture to enter store. These merchandisers were
designed for use in stores were temperature &
humidity does not exceed 75° F and 55% H.
Stainless Steel Cleaning and Care
There are three basic things, which can break down your
stainless steel’s passivity layer and allow corrosion.
1. Mechanical Abrasion
MechanicalAbrasion means those things that
will scratch the steels surface. Steel Pads, wire
Brushes, and Scrapers are prime examples.
2. Water
Water comes out of our tap in varying degrees of
hardness. Depending on what part of the country
you live in, you may have hard or soft water. Hard
water may leave spots. Also, when heated, hard
water leaves deposits behind that if left to sit, will
break down the passive layer and rust your stainless
steel. Other deposits from food preparation and
service must be properly removed.
3. Chlorides
Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the worst
perpetrators of chlorides can come from household
and industrial cleaners.
Don’t Despair! Here are a few steps that can help prevent
stainless steel rust.
1. Use the Proper Tools
When cleaning your stainless steel products, take
care to use non-abrasive tools. Soft Clothes and
plastic scouring pads will NOT harm the steel’s

User Information (Cont'd)
passive layer. Stainless steel pads can also be
used but the scrubbing motion must be in the same
direction of the manufacturer’s polishing marks.
2. Clean With the Polish Lines
Some stainless steels come with visible polishing
lines or “grain”. When visible lines are present, you
should ALWAYS scrub in a motion that is parallel to
them. When the grain cannot be seen, play it safe
and use a soft cloth or plastic scouring pad.
3. Use Alkaline, Alkaline Chlorinated or
Non-chloride Containing Cleaners
While many traditional cleaners are loaded
with chlorides, the industry is providing an ever
increasing choice of non-chloride cleaners. If you
are not sure of your cleaner’s chloride content
contact your cleaner supplier. If they tell you that
your present cleaner contains chlorides, ask for
an alternative. Also, avoid cleaners containing
quaternary salts as they also can attack stainless
steel & cause pitting and rusting.
4. Treat your Water
Though this is not always practical, softening hard
water can do much to reduce deposits. There
are certain filters that can be installed to remove
distasteful and corrosive elements. Salts in a
properly maintained water softener are your friends.
If you are not sure of the proper water treatment, call
a treatment specialist.
5. Keep your Food Equipment Clean
Use alkaline, alkaline chlorinated or non-chlorinated
cleaners at recommended strength. Clean
frequently to avoid build-up of hard, stubborn stains.
If you boil water in your stainless steel equipment,
remember the single most likely cause of damage is
chlorides in the water. Heating cleaners that contain
chlorides has a similar effect.
6. RINSE, RINSE, RINSE
If chlorinated cleaners are used you must rinse,
rinse, rinse and wipe dry immediately. The sooner
you wipe off standing water, especially when sit
contains cleaning agents, the better. After wiping the
equipment down, allow it to air dry for the oxygen
helps maintain the stainless steel’s passivity film.
7. Never Use Hydrochloric Acid (Muriatic Acid) on
Stainless Steel
8. Regularly Restore/Passivate Stainless Steel
9. Shelf Weight Limits
