Elite Service Merchandisers
HUSSMANN CORPORATION, Bridgeton, MO 63044-2483 U.S.A.
NSF LISTING
These merchandisers are manufactured to
meet ANSI / UL 471 standard requirements
for safety. Proper installation is required to
maintain this listing. Near the serial plate,
each case carries a label identifying the type of
conditions for which the merchandiser was
tested.
ANSI/NSF-7 Type I – Display
Refrigerator / Freezer Intended for 75°F /
55%RH Ambient Application
ANSI/NSF-7 Type II – Display
Refrigerator / Freezer Intended for 80°F /
55%RH Ambient Application
ANSI/NSF-7 – Display Refrigerator
Intended for Bulk Produce
FEDERAL / STATE REGULATION
These merchandisers, at the time they are
manufactured, meet all federal and state /
provincial regulations.
LOCATION
These merchandisers are designed for dis-
playing products in air conditioned stores
where temperature is maintained at or below
the ANSI/NSF-7 specified level and relative
humidity is maintained at or below 55%.
Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efficiency.
Like other merchandisers, these are sensi-
tive to air disturbances. Air currents passing
around merchandisers will seriously impair
their operation. Do NOT allow air condition-
ing, electric fans, open doors or windows, etc.
to create air currents around the merchandisers.
Product should always be maintained at 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
the life of the product.
SHIPPING DAMAGE
All equipment should be thoroughly exam-
ined for shipping damage before and during
unloading. This equipment has been carefully
inspected at our factory. Any claim for loss
or damage must be made to the carrier. The
carrier will provide any necessary inspection
reports and/or claim forms.
Apparent Loss Or Damage
If there is an obvious loss or damage, it must
be noted on the freight bill or express receipt
and signed by the carrier’s agent; otherwise,
carrier may refuse claim.
Concealed Loss Or Damage
When loss or damage is not apparent until
after equipment is uncrated, retain all packing
materials and submit a written request to the
carrier for inspection, within 15 days.

MERCHANDISERS SHIPPED
WITH END INSTALLED
Important:Be careful not to damage the
factory installed end while moving the case.
Make sure that tools are positioned past the
end and beneath the merchandiser’s support
bar.
SHIPPING BRACES
Move the fixture as close as possible to its
permanent location and then remove all pack-
aging and shipping braces. Check for damage
before discarding packaging. Remove all
separately packed accessories such as kits, and
shelves.
Remove all nut retainers used with shipping
braces. NSF certification requires the use of
ANSI Standard nuts and bolts with not more
than two (2)threads showing after installa-
tion.
SHIPPING RIDER
Each case is shipped on a rider to protect
factory-installed legs, and to make position-
ing the case easier. Remove the rider after the
case has been positioned.
Note: Once the rider is removed, the case
must be lifted –NOT PUSHED– to repo-
sition. To remove the rider, remove screws
attaching each leg to rider. Remove screws
holding rider cross-members, then slide
cross-members out from between sides. Once
cross-members are out, slide the sides out.
Do NOT stand or walk on top of
merchandiser because. Do not place items
or flammable materials atop the unit.

This warning does not mean that Hussmann products
will cause cancer or reproductive harm, or is in
violation of any product-safety standards or
requirements. As clarified by the California State
government, Proposition 65 can be considered more of
a‘right to know’ law than a pure product safetylaw.
When used as designed, Hussmann believes that our
products are notharmful. We provide the Proposition
65 warning to stay in compliance with California State
law. It is your responsibility to provide accurate
Proposition 65 warning labels to your customers when
necessary. For more information on Proposition 65,

CASE LEVELING
Merchandisers must be installed level to
ensure proper operation of the refrigeration
system and to ensure proper drainage of
defrost water. During all steps of setting, join-
ing and leveling cases, close attention to glass
position and operation must be maintained.
Please review all steps and photos before
making any adjustments. DO NOT make any
glass adjustments until individual case is set
and level.
Preparation
1. Using store blueprints, measure off and
mark on floor the exact dimensions/loca-
tions of the case footprint.
2. Snap a chalk line for the front and rear
positions of the base legs.
3. Mark the location of each joint from front
to back lines.
4. FLOORS ARE NOT LEVEL!!! When
working with two or more cases to be
joined, the whole lineup must be leveled
on the same plane, left to right and front
to back. This means that the entire line-
up must be brought up to the level of the
highest case in the lineup.
Along the lines previously marked, find
the highest point of the floor by:
• Walking the floor and noticing any
dips or mounds;
• Using a string level; and
• Using a transit.
The top cylinders, which allow the raising
and lowering of this glass, have been carefully
installed and tested for the proper tension
before shipment. However, during shipment
and storage, the lubricant inside the cylinders
may have settled. This settling can cause ex-
cessive or uneven tension on the glass to the
point of breakage.
To avoid any damage, please do the fol-
lowing before completely raising the front
glass.
1. Slowly raise and lower each glass section
6 times to a height of 6 in. (152 mm).
2. Increase the height to about 12 in. (305
mm) and raise and lower the glass 6
times.
3. Then raise the glass to the full extension
and lower.
This should release any settled lubricant in
the cylinders and prevent any stress on the
front glass. Leveling and adjustment proce-
dures begin on Page 1-3.
Read before raising front glass to prevent
injury from broken or falling glass.

Leveler Adjustment
Position the first case at the highest
point. Set a long level (4 ft [1220 mm] or
more) on the upper front panel of the
case. Use an open-end wrench to turn leg
levelers until the case is level from end to
end and from front to back. Check all 6
legs on 8 ft (2438 mm) cases, or 8 legs on
12 ft (3658 mm) cases.
Note: To avoid removing concrete floor-
ing, begin lineup leveling from the highest
point of the store floor.
Attention to glass position is critical during
the leveling process.
Adjusting leg levelers will affect the posi-
tion of the glass. Make certain that the
glass is square with the case, and does not
interfere with other glass or case ends.
If the glass is still out of alignment, refer
to the following Front Glass Positioning
instructions.

To prevent injury from falling
glass during adjustment, one
person must support glass
while a second person makes
adjustments.
Do not adjust glass until case is level.
In many instances, proper leveling will align
glass without further adjustment.

HUSSMANN CORPORATION, Bridgeton, MO 63044-2483 U.S.A.
Vertical Adjustment
The position of the front edge of the glass is
vertically adjustable to ensure proper fit. Do
not attempt to make glass adjustments before
leveling the case. All steps of setting, joining
and case leveling are critical to glass position.
Glass alignment may be affected if merchandisers
are not leveled.
Check for level:
1. In a lineup position, first case is posi-
tioned at the highest point in the floor.
2. All 8 legs must be adjusted or shimmed to
level case.
3. Check case level with a 4ft minimum level,
also front to back. Place level on front glass
contact point (top rail).
Front glass is adjusted from the factory.
However, there may be instances when the
glass may need adjustment in the field.
Joined or with ends
Check that glass is square with the case and
does not interfere with other glass or case
ends.

Check the following to improve opening or
closing of the case front glass.
1. Has the case been leveled according to the
installation instructions. If not, level the case.
2. Is the glass handle installed correctly?
3. Verify the glass is bottomed out in the
handle. The handle should not be bowed
along its length. Bowing is an indication the
handle is not properly installed.
If the handle is not positioned correctly, it
must be removed. The handle is held in place
with silicone. Remove the handle by pulling
it away from the glass. Do not use tools to
pry handle from glass. Old silicone must be
cleaned off the handle and glass. Apply new
silicone into the handle, and firmly press han-
dle onto the glass.

1. Apply butyl tape across the bottom joint.
Be sure to extend the tape up the back
and front of the case.
2. Use field-supplied silicone to fill any gaps
between the front support brackets.
INSTALLING BUMPERS
Elite bumpers are shipped as a continuous
roll. Once installed the continuous bumper
helps to disguise the joint locations, giving the
lineup a smoother look.
1. Unroll the bumper and allow it to rest at
room temperature for 24 hours prior to
installation to minimize bumper shrinkage
after installation.
2. Slide end caps onto retainer at right and
left ends of lineup. Align with slot in
retainer, then fasten with screws provided.
3. Measure the distance between inside end
of caps and add 1/8inch (3mm) for each
4ft (1220mm). Adding the additional
material will compensate for stretching
which occurs during installation.
4.
Cut the bumper to length with a miter saw
for a precise, right-angle cut.
5. Lubricate the inside of the vinyl with
soapy water or silicone spray.
6. Starting at the left end of the line up, butt
end of the vinyl bumper against end cap.
While applying pressure, bend back vinyl
top so that vinyl legs are positioned with-
in the base grooves. Roll vinyl bumper
over full length of retainer, then tap with
rubber mallet to ensure vinyl is securely
locked into retainer.
7. If necessary wipe clean with any house-
hold cleaning product.

Elite Service Merchandisers
HUSSMANN CORPORATION, Bridgeton, MO 63044-2483 U.S.A.
REFRIGERANT
The correct type of refrigerant will be
stamped on each merchandiser’s serial plate.
The case refrigeration piping is factory sealed,
pressurized and leak tested. Before making
refrigeration hookups, depress universal line
valve to ensure that coils have maintained
pressure during shipment.
REFRIGERANT PIPING
Connection Location
The refrigerant line connections are at the
right- hand end of the merchandiser (as
viewed from the front) beneath the display
pans. A sticker marks the location of the con-
nection “pod.” The installer must saw a hole
through the pod to exit the case. After con-
nections have been made, seal this outlet thor-
oughly. Seal both the inside and the outside.
We recommend using an expanding polyure-
thane foam insulation.
Multiplexing
Piping of merchandisers operating on the
same refrigeration system may be run from
merchandiser to merchandiser. donot run
refrIgerant lInes through merchandIsers
that are not on the same refrIgeratIon
system branch as this may result in poor
refrigeration control and compressor failure.
Interconnecting piping inside the merchandis-
er must be located as shown below to allow
room for lifting the hinged fan plenums and
for clearance beneath the display pans. The
interconnecting piping may be run outside the
merchandiser.
REFRIGERATION / ELECTRICAL

Display Pan
Refrigerant vapor is hazardous to your health
and can cause death.
Avoid breathing refrigerant and lubrication
vapor or mist. Exposure may irritate eyes,
nose and throat. If accidental system dis-
charge occurs,ventilate work area before
resuming service.
Always wear safety goggles and protective
gloves when working with refrigerants.
Contact with refrigerant may cause injury.
Disconnect hoses with extreme caution! All
hoses may contain liquid refrigerant under
pressure.
Be sure that any room where you are working
is thoroughly ventilated, especially if a leak
is suspected.
Read all safety information regarding the
safe handling of refrigerant and refrigerant
oil, including the Material Safety Data Sheet.
MSDS sheets can be obtained from your
refrigerant supplier.
Refrigeration lines are under pressure
and should be depressurized before
attempting to make any connections.
When brazing pipes, be sure to use the
insulation blanket shipped with the
merchandiser to prevent fire or damage
to the plastic case bottom.

Line Sizing
Refrigerant lines should be sized as shown on
the refrigeration legend that is furnished for
the store or according to ASHRAE guidelines.
Refer to the information on the next page for
branch line piping of Hussmann Equipment.
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ft (9144mm) from the merchandiser.
Additional insulation for the balance of the
liquid and suction lines is recommended wher-
ever condensation drippage is
objectionable or lines are exposed to ambient
conditions.
SUCTION LINE
• Pitch in direction of flow.
• May be reduced by one size at one third of
case run load and again after the second
third. Do not reduce below the case suction
line size.
• Case suction
lines should enter
at the top of the
branch line.
LIQUID LINE
• May be reduced by one size after one half
the case run load. Do not reduce below the
case liquid line connection size.
• Take-offs to case liquid lines should exit
the bottom of the branch liquid line.
Provide an expansion loop for each evap-
orator take-off. (Minimum 3in. [76mm]
loop.)
CONTROL SETTINGS
Merchandiser data sheets are shipped with this
manual. The data sheets provide case control
settings and defrost data.
An evaporator pressure regulator or EPR (pri-
mary control) and a 3–5ºF (1.7– 2.7ºC) dif-
ferential thermostat (secondary control) must
control refrigeration temperature. The EPR
must be set to maintain the proper saturated
evaporator temperature as listed in the data
sheets. The thermostat must be set a couple
degrees colder than the discharge air tempera-
ture specified in the data sheets. The ther-
mostat will prevent product freezing should
the EPR temperature drift downward during
reduced load periods (lights off, lower ambi-
ent). The thermostat will be wired to control
the compressor motor contactor (single com-
pressor) or a liquid line solenoid valve (parallel
compressor systems).
