4. Cut and Plan Views
These service-type merchandisers have been
specifically designed for bakery departments. The full
length, curved glass front provides complete product
visibility. The
SGB-N, non-refrigerated model, is designed to display
fresh bakery products that have fast turnover and require
no refrigeration. The SGB-R, and SGB-S/C, refrigerated
bakery merchandisers are designed for use only in air
conditioned stores where temperature and humidity are
maintained at or below 75°F dry bulb temperature and
55% relative humidity.
• Review the SGB Technical Data Sheet to verify
thermostat setting. Do not set temperature too cold,
as this causes product dehydration.
• Temperatures should be achieved by a
T-STAT and suction solenoid at each case. Do
not use EPR valves, liquid line solenoids or
electronic control devices of any kind. These
controls allow temperature swings causing
product dehydration and excessive energy
consumption.
• Defrost cycles should be set according to the SGB
technical data sheet.
• Work and rotate product - not to exceed a four (4)
hour period.
5. Installation
Location
Like other open merchandisers, these are sensitive to air
disturbances. Air currents passing around merchandisers
will seriously impair their operation. Do NOT allow air
conditioning, electric fans, open doors or windows, etc., to
create air currents around the merchandisers.

Bumper Installation Instructions
Step 1: Make sure the aluminum channel
and end caps are installed.
Step 2: Use silicone lubricant to help the
bumper slide into the channel.
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.

6. Shipping Braces
(Note to all Merchandisers)
Move the fixture as close as possible to its permanent
location and then remove all packaging. Check for
damage before discarding packaging. Remove all
separately packed accessories such as kits and shelves.
Do NOT remove shipping braces until the
merchandisers are properly anchored to the floor.
Merchandisers are top heavy and could tip over
causing serious injury. Merchandisers must
be braced before removing the lag bolts.
Bag Rack Shipping Brace
On non-refrigerated cases, the shipping braces in the
middle should be removed. Its purpose is to protect the
bag rack during shipment.
Leveling
Merchandisers must be installed level to ensure proper
operation of the refrigeration system and to ensure
proper drainage of defrost water. Place prybar under
metal base and lift. DO NOT LIFT END PANEL. Turn
leveler, with supplied wrench, (one wrench per order)
clockwise to raise, counter clockwise to lower. Repeat
process with other levelers until case is level.
NOTE: To avoid removing concrete flooring, begin lineup
leveling from the highest point of the store.
7. Joining
Merchandisers are of sectional construction which
means that two or more may be joined in line yielding
one long continuous display requiring only one pair of
ends. Joint kits and instructions are shipped separately.
8. Exterior Loading
Do NOT walk on top of merchandiser or damage to
the merchandiser and serious personal injury could
occur. They are not structurally designed to support
excessive external loading such as the weight of a
person.

9. Plumbing
Waste Outlet and Water Seal
On refrigerated merchandisers, remote and self-
contained, the waste outlet is centrally located and
accessible from the rear of the case.
For remote refrigerated merchandisers, field install the
water seal/90 elbow assembly and coupling, and attach
3/4" PVC drip piping in the desired orientation. See
illustration. The self-contained merchandiser empties
into an evaporator pan.
Installing Drip Piping
NOTE: PVC-DWV solvent cement is recommended. Follow the
Hussmann’s instructions.

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 drip pipes to insure a proper installation:
1. Never use drip piping smaller than the nominal
diameter of the pipe or water seal supplied with the
merchandiser.
2. When connecting drip piping, the "water seal" must
be used as part of the drip piping to prevent air
leakage or insect entrance. Never use two water
seals in series in any one drip pipe. Double water
seals in series will cause an air lock and prevent
draining.
3. Pitch the drip piping in the direction of flow. There
should be a minimum pitch of 1/8" per foot.
4. Avoid long runs of drip piping. Long runs make it
impossible to provide the pitch necessary for good
drainage.
5. Provide a suitable air break between flood rim of the
floor drain and outlet of drip pipe.
6. Prevent condensate drains from freezing:
a. Do not install drip pipes in contact with non-
insulated suction lines. Suction lines should
be insulated with a nonabsorbent insulation
material.
b. Where drip pipes are located in dead air
spaces, such as between merchandisers or
between a merchandiser and a store wall,
provide means to prevent freezing.
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.

10. Refrigeration
Refrigerant Type
Unless otherwise specified on the factory order, remote
and self-contained merchandisers are equipped for
operation on R-404A refrigerant. The correct type of
refrigerant will be stamped on each merchandiser’s
serial plate located inside the merchandiser.
Refrigeration Piping
Liquid Suction
3/8" O.D. 5/8" O.D.
The refrigerant line connections are behind the rear
close-off panel, underneath the drain tub, on the left
hand end of the merchandiser as viewed from the
rear. After connections have been made, seal this
outlet thoroughly. Seal both inside and the outside. We
recommend using an aerosol dispensed urethane type
of insulation. See SGB technical data sheet for proper
duration and frequency. Self contained cases have
individual defrost time clocks. When power has been
applied, set the time clock to the proper duration and
frequency.
The time clock is located behind the front panel under
the case. Turn the clock dial counterclockwise until the
pointer is directed to the current time of day.
Multiplexing - Piping of merchandisers operating
on the same refrigeration system may be run from
merchandiser to merchandiser through the end frame
saddles provided for this purpose. DO NOT RUN
REFRIGERANT LINES THROUGH MERCHANDISERS
THAT ARE NOT THE SAME REFRIGERATION
SYSTEM as this may result in poor refrigeration control
and compressor failure.
Line Sizing - Refrigerant lines should be sized as
shown on the refrigeration legend that is furnished for
the store (not furnished by Hussmann). If a legend has
not been furnished, refer to the Hussmann Application
Engineering Manual for guidance.
Oil Traps - P-TRAPS (oil traps) must be installed at the
base of all suction line vertical risers.
Pressure Drop - Pressure drop can rob the system
of capacity. To keep the pressure drop to a minimum,
keep the refrigerant line run as short as possible using a
minimum number of elbows. Where elbows are required,
use long radius elbows only.
Insulation - The suction and liquid lines should be
clamped or taped together and insulated for a minimum
of 30’ from the merchandiser. Additional insulation is
recommended wherever condensation drippage is
objectionable.

11. Controls and Adjustments
The objective of the controls and settings listed in this
section is to maximize product shelf life. Not complying
with these instructions will increase spoilage rate due to
drying of the product and could cause sweating on the
front glass if operated too cold.
Allow bakery products to reach store ambient conditions
after preparation just prior to display. This is essential to
maximize the shelf life of perishables.

12. User Information
Stocking
In order to maximize product life, maintain a constant
and proper product temperature from the time the
product is received through storage, preparation and
display.
Products should not be placed in merchandisers until
all refrigeration controls have been adjusted and
merchandisers are at proper operating temperature.
Care should be taken to place the bakery trays all the
way to the front of the shelf. This avoids blocking the
rear refrigerated air discharge. The load limit decals are
affixed to the interior of the merchandiser. Again, air
discharge and return air flow must be unobstructed
at all times to provide proper refrigeration.
There is also a row of vents located at the base of the
front glass, just above the front rub rail. These vents
allow a gentle air flow across the front glass from the
ambient fans that prevents any condensation on the
glass. Do Not place any signs or other restrictive
objects on the front of the merchandiser that will
block these vents.
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,
merchandisers should be thoroughly cleaned, all debris
removed and the interiors washed down, weekly.
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, ends and service doors to warm
before applying hot water.
Exterior Surfaces -The exterior surfaces must be
cleaned with a mild detergent and warm water to protect
and maintain their attractive finish. Never use abrasive
cleansers or scouring pads.
Front Glass - DO NOT use the front glass as a
support during cleaning. Removal of the glass is NOT
recommended.
Interior Surfaces -The lower display decks are
removable by sliding open rear drawer and lifting them
up and out. The interior surfaces may be cleaned with
most domestic detergents, ammonia based cleaners and
sanitizing solutions with no harm to the surface.
Shut off fan during cleaning
Important Steps
1. For temperature settings, please see the SGB
technical data sheet.
2. Temperature control should be by means of a

10
T-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 temperature swings causing dehydration and
excessive energy consumption.
3. Product should be worked and rotated on a regular
basis, not to exceed a 4-hour period.
4. At night, turn off case lights and cover the product
with a damp (not wet) cloth similar to cheese cloth
(etc.). This should be washed out in the morning and
kept in a walk-in box during the day so that it is cool
and moist when covering the product.
5. Discharge air temperature should be approximately
26°F, with between 150-200 FPM air velocity. Do not
display product directly within the air discharge.
6. Clean Humidity system a minimum of every 90 days
for proper system operation.
Case Cleaning
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)
C
A
U
TI
O
N
Do Not Use:
• Mineral oil based solutions, as these will dissolve
the butyl sealants used in the construction of the
merchandisers.
• Abrasive cleansers and scouring pads, as these will
mar the finish.
Do:
• Remove the product and all loose debris to avoid
clogging the waste outlet.
• Thoroughly clean all surfaces with soap and hot
water. Do NOT use steam or high water pressure
hoses to wash the interior. These will destroy the
merchandisers’ sealing causing leaks and poor
performance.
• Rinse with hot water, but do NOT flood. Never
introduce water faster than the waste outlet can
remove it.
NOTE: Self-contained Models
The evaporator pan must be monitored
for overflow conditions. Provide drainage if
necessary. After cleaning and rinsing, purge the pan
of any standing water.
• Care should be taken to minimize direct contact
between fan motors and cleaning or rinse water.
• Allow the merchandisers to dry before resuming
operation.
• When cleaning lighted shelves, wipe down with a
damp sponge or cloth so that water does not enter
the light channel. Do NOT use a hose or submerge
shelves in water.
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
Mechanical Abrasion 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
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
User Information (Cont'd)

11
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
User Information (Cont'd)
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
13. Electrical
Wiring Color Code
Rear Close-off Panel
To perform electrical and refrigeration work, remove the
rear closure panel by loosening the sheet metal screws.
Replace when work is complete.
Note: Self-contained Models - Do NOT block the vent openings
on the rear closure panel. These allow intake and
exhaust air for the condensing unit. Vents only appear
on self-contained models.
Electrical
Self-Contained Model Installation - Medium temperature
merchandisers need only to be connected to a
120V/60 Hz electrical supply. Low temperature
merchandisers need to be connected to both a
120V/60 Hz and 220V/60 Hz electrical supply.
Connections - All wiring must be in compliance with
NEC and local codes. All electrical connections for the
nonrefrigerated model are to be made in the electrical
panel. Electrical connections for refrigerated models
are made in the electrical box on the back of the case
behind the rear close-off panel.
Field Wiring - Field wiring must be sized for
components amperes stamped on the serial plate. Actual
ampere draw may be less than specified. Always check
the serial plate.
Post Construction Clean-up - After the first two weeks
of a major store remodel or new store operation, the
grill should be removed and the condensing unit and
condenser face cleaned due to the accumulated dirt and
debris generated during construction.
