NSF CERTIFICATION
These merchandisers are manufactured to meet
ANSI / National Sanitation Foundation (NSF
®
)
Standard #7 requirements. Proper installation is
required to maintain certification. Near the serial
plate, each case carries a label identifying the
type of application for which the case was
certified.
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
MODEL DESCRIPTION
The D5RRI and D5RRIS models are designed
for installation against an opening in the cooler
wall. The cases are open at the rear. Once
installed, product can be rolled directly from
the cooler through the rear of the caser into the
refrigerated display area.
The D5RRI is a self-supporting model with the
canopy and front sections connected by welded
end supports.
The D5RRIS is manufactured in two sections:
a Coil Package and a Front Package. The coil
package is to be suspended against the cooler
wall, above the opening, from an adequate
supporting structure in the store. The front
package completes the D5RRIS model once it
has been aligned with the coil package and
anchored to the floor.
Both models are designed to align with the D5L.
LOCATION
These cases are designed for displaying 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 cases in direct sunlight, near
hot tables or near other heat sources could impair
their efficiency.
Like other cases, these are sensitive to air disturbances. Air currents passing around cases will
seriously impair their operation. Do NOT allow
air conditioning, electric fans, open doors or
windows, etc. to create air currents around the
cases.
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 examined
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.
INSTALLATION
Do not walk or put heavy objects on case.

EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious personal injury could occur. T
HEY ARE NOT STRUCTURAL-
LY DESIGNED TO SUPPORT EXCESSIVE EXTERNAL
LOADING such as the weight of a person. Do not
place heavy objects on the case.
MERCHANDISER ENDS
Ends for the D5RRI and D5RRIS rear load dairy
models are shipped separately to be field installed
after the cases are installed in the cooler wall.
Refer to separate instructions shipped with the
ends.
SHIPPING BRACES
Move the case 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.
The D5RRI is top-heavy and must be supported
and moved with care at all times until it has been
securely anchored. It must be supported while it
is being unfastened from the skid and when it is
removed from the skid. Once the skid has been
unfastened, never leave the fixture unsupported or
unattended until it has been anchored.
LEVELING
Merchandisers must be installed level to ensure
proper operation of the refrigeration system and
to ensure proper drainage of defrost water. When
leveling merchandisers, use a carpenter’s level as
shown. Leveling shims are provided with each
case for use if needed. The shims are big enough
so that you can level adjoining merchandisers at
the same time using one shim.
NOTES:
• B
EGIN LINEUP LEVELING FROM THE HIGHEST POINT
OF THE STORE FLOOR.
• If shimming two corners, check to see if a shim is
needed in the center of the case. If a gap exists
between the support rail of the case and the floor, a
shim should be placed in the center.
Do NOT remove shipping braces until
the merchandisers are positioned
for installation. Once unfastened,
NEVER LEAVE THE MERCHANDISER
UNSUPPORTED OR UNATTENDED
until it has been anchored.
Do not walk or put heavy objects on case.

INSTALLING D5RRIS
Overview
The coil package must be suspended above the
cooler wall opening from an adequate support
structure. It is imperative that both the method
and the materials used to suspend the coil package be of sufficient strength to support the coil
package.
These models are designed for use with roll-in
carts or free-standing (unattached) shelving.
DISCLAIMER: These methods of securing the
coil package are suggestions only. It is the
responsibility of the store designer, installer and
end user to ensure the store’s structural capacity.
Hussmann assumes no liability for consequences
resulting from failure of store structure or material used in installation.
Two 15/
8 x 1
5
/
8 inch (41 x 41 mm) channel struts
are provided for hanging the coil package. These
struts extend the full length of the case and are
bolted to the case at the factory. Use 1/2 in. (12.7
mm) clamp nuts to secure the hanging rods to the
struts. Although these struts allow flexibility in
hanging rod location, the end support rods must
be within 12 in. (305 mm) of the coil package
end. For a 12 ft (3658 mm) coil package, the center hanging rods must be within 12 in. (305 mm)
of the center of the case.

Installing Coil Package
Attach the coil package to the selected store
structural support using the suggested drop rod
size, quantity and fastening method, or as locally engineered. The coil package must be leveled.
Apply silicone sealant between the “L” bracket
and bottom of cooler wall as shown. Fasten the
“L” bracket at the top rear of the coil package to
the cooler wall to prevent sway or lateral movement. The “L” bracket has holes for this purpose.
Once lineup is complete, apply silicone or butyl
sealant on outside where “L” bracket and wall
meet, and on inside where wall and bracket meet
to prevent condensation in walls. Sealing is also
required to facilitate cleaning to NSF guidelines.
The channel struts with clamping nuts are provided to fasten the suspending rods. When tightening
1
/2 in. (12.7 mm) threaded rods into nuts, ensure
that the rods are firmly screwed into place.
Vibration pads must be used if a machine room
or or other machinery is located above the structure that supports the coil package.
Installing Front Package
Align the front section with the canopy. Shim as
necessary to maintain level. Fasten anchor brackets to floor. Seal as indicated.

INSTALLING D5RRI
The D5RRI must be securely anchored to the
floor and cooler wall after it has been leveled in
its permanent position. Prelocated anchoring
holes are provided in the front assembly,
uprights, side braces, and top “L” bracket.
Sealing
For proper performance, safety and sanitation,
apply a generous bead of sealant betwwen the
D5RRI and the floor, between the D5RRI top
and sides and the cooler wall, around the interior perimeter of the base at the floor, and along
the exterior front of the base at the floor.
REAR CURTAIN INSTALLATION
Rear curtains are provided with each case, two
per 8 ft model, 3 per 12 ft model. Curtains should
be installed just before start-up to prevent damage.
1. Slide all hangers onto track at rear of the
case. Use ALL hangers so the curtains will drape
properly.
2. Snap a stop clip onto each end of the track.
3. Hang curtains on hangers.
JOINING
Sectional construction means that two or more
merchandisers may be joined in line yielding one
long continuous display requiring only one pair
of ends. Joint kits and instructions are shipped
with each case.
To join like fixtures, a joint assembly is
required. To join unlike fixtures, or like fixtures
operating at different temperatures, a 1
1
/
2 inch
(38 mm) partition kit is required.
A
LL JOINTS MUST BE AIR-TIGHT TO PREVENT
FORMATION OF ICE OR CONDENSATION.
Refer to separate joining instruction shipped
with each case
INSTALLING PARTITIONS

REFRIGERANT
The correct type of refrigerant will be
stamped on each case’s serial plate. The case
refrigeration piping is leak tested, factory
sealed and pressurized. Before making refrigeration hookups, depress the universal line
valve to ensure that coils have maintained
pressure during shipment.
REFRIGERANT PIPING
Connection Location
The refrigerant line connections are at the lefthand end of the case (as viewed from
the front).
After connections have been made, seal this outlet thoroughly. Seal both the inside and the outside. We recommend using an expanding
polyurethane foam insulation.
Multiplexing
Multiplex piping must be run above the top of the
coil package in the area shown. Observe proper
suction pipe joining practices and insulate all
suction piping outside the case to prevent drippage from condensate.
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.
