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
LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where tempera-
ture 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 sun-
light, near hot tables or near other heat sources
could impair their efficiency.
Like other merchandisers, these are sensitive to air
disturbances.Air currents passing around merchan-
disers will seriously impair their operation. Do
NOT allow air conditioning, 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.
The exterior frames on these cases provide space
for air circulation. However, in high ambient
conditions, sweating may still occur. If this
happens install a method of forced ventilation such
as a fan ventilation kit.
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.
CAUTION
!
Exercise caution at all times when moving
merchandisers with “L” shaped riders.
They are top heavy and should
EVER be left in the vertical position.
WARNING
!

1-2 INSTALLATION
SHIPPING BRACES
Move the merchandiser as close as possible to
its permanent location and then remove all
packaging. Check for damage before discarding
packaging. Remove all separately packed acces-
sories such as kits and shelves.
EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious personal
injury could occur. THEY ARE NOT STRUCTURALLY
DESIGNED TO SUPPORT EXCESSIVE EXTERNAL LOAD-
ING such as the weight of a person. Do not place
heavy objects on the case.
MERCHANDISERS SHIPPED
WITH END INSTALLED
If the case was shipped with the end installed, two
long bolts were used to hold the shipping brace to
the end. If the shipping bolts are reinserted after
removing the brace, they will extend into the prod-
uct area. THEREFORE,BE SURE TO REPLACE THESE
BOLTS WITH THE SHORTER BOLTS PROVIDED.
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 merchan-
diser’s support bar.
ANCHORING
Because of the merchandisers' forward projection,
they must be anchored to the floor to prevent them
from tipping forward. Each merchandiser should
be lagged to the floor through its rear skid.
Anchors should be placed approximately 8 to
12 in. (203 mm to 305 mm) from each end and in
the center of the rear skid. Some merchandisers
have holes in the rear skid for this purpose.
Once the merchandisers are properly anchored,
remove shipping braces.
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
merchandiser for use if needed. The shims are
12 in. (305 mm) long and 3 in. (76 mm) wide so
that you can level adjoining merchandisers at the
same time using one shim.
P/N 0416183C
Use Levels Here
Shim
Do OT 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.
WARNING
!

1-3
Notes:
•BEGIN 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 merchandiser. If a
gap exists between the support rail of the
merchandiser and the floor, a shim should be
placed in the center.
JOINING INSTRUCTIONS
Sectional construction means that two or
more merchandisers may be joined in line yielding
one long continuous display requiring only one
pair of ends. To join like fixtures, a joint kit is
required. To join unlike fixtures, or fixtures of
different temperature applications, an insulated
partition kit is required. Joint and partition kits are
shipped separately; instructions are included with
each kit.
ALL JOINTS MUST BE AIR-TIGHT TO PREVENT
FORMATION OF ICE OR CONDENSATION.
Refer to separate Joint Instruction shipped
with case.
OFFSETTING BUMPERS AND TOP RAIL
Offsetting the bumpers and top rails helps to
disguise the joint locations, giving the lineup a
smoother look.
1. Locate short starter bumpers and top rail. They
are shipped with the left-end kit.
2. Remove factory installed top rails and bumpers
from cases as follows:
a.To remove top rails, push rail toward the
back of the case with one hand while lift-
ing the top edge off the light channel with
the other hand. See following drawing.
b.Starting at one end, carefully peel bottom
of top rail free of color panel and set the
rail inside the case.
c. Remove upper and lower bumpers by
pulling bumper away from bumper retain-
ers. Be careful not to lose the internal joint
trims on the upper bumpers.

3. Starting at the left end of the line up, install the
upper bumper starter section first. To install,
a. Position internal joint trims so that the first
is flush to the left-end panel and the second
is centered between the starter bumper and
the full length bumper as shown below.
b. Install full length bumpers
and internal trims offset
across joints. Make sure that
no gaps exist between sec-
tions. Continue installing
the upper bumpers the
length of the line up. Do
NOT install the last upper
bumper section at this time.
This section will be installed
in the last step.
4. Install lower bumper starter and
full length lower bumpers by
simply pushing them into place.
Start at the right end of the line-
up for additional camouflage.
There are no internal joint trims
on the lower bumpers.

5. Return to the left end of the line up and posi-
tion the starter section of the top rail as shown.
NOTE: The top rail
should not be installed
until the upper bumper
is securely in place.
6. Push the bottom portion of the short top rail
section down over the color panel. It helps if
you lift the top with your other hand as shown.
You will hear and feel the trim “snap” into
place.
NOTE: The
trim must
“snap” to
be properly
positioned.
7. Use one hand to push the top rail toward the
rear of the case while using the other hand to
“snap” the top section down over the edge of
the light channel as shown.
Again, be
sure it
“snaps”
into place.
8. Install full length top rails using the same
procedures. Continue installing the top rails
the length of the line up. Do NOT install last
section at this time.
9. Once all except the last sections of upper
bumper and top rail have been installed refrig-
erate the case line up for at least six (6) hours.
The last sections of upper bumper and top
rail should be kept inside a refrigerated case
or cooler during this time. This will allow the
bumpers and top rails to contract.
10. Go to the right end of the line up and tap the
top rail and bumpers to close any gaps.
11. Measure and cut last sections of top rail and
bumpers. Use a miter box and fine-tooth saw
to cut last bumpers and top rail to length.
Install the last sections.
Note: If part of plastic top rail pops loose, remove
that section of top rail and re-install according to
Steps 6 and 7 above. Trying to re-install only the
popped part may not secure the top rail, and may
damage the top rail, color panel and light channel.

SPLASHGUARD BRACKET
AND JOINT SUPPORT
Install Splashguard Bracket
Position splashguard brackets to the merchandiser
and level to the floor. Each bracket has a slot at the
rear of the bracket where it attaches to the mer-
chandiser. Tighten screws to secure the brackets.
Install Splashguard Joint Support
Position the joint support across the brackets as
shown below. Fasten with sheet metal screws.

REFRIGERANT
The correct type of refrigerant will be stamped
on each merchandiser’s serial plate located on
the left-hand end of the interior top liner. The
case refrigeration piping is leak tested, factory
sealed and pressurized. Before making refrig-
eration hookups, depress Schrader 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 connection “pod.” The installer
must saw a hole through the pod to exit the case.
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
Piping of merchandisers operating on the same
refrigeration system may be run from merchan-
diser to merchandiser DO NOT RUN REFRIGERANT
LINES THROUGH MERCHANDISERS THAT ARE NOT
ON THE SAME REFRIGERATION SYSTEM or BRANCH
as this may result in poor refrigeration control
and compressor failure.
Interconnecting piping inside the merchandiser
must be positioned to allow room for lifting the
hinged fan plenums and for clearance beneath the
display pans.
Line Sizing
Refrigerant lines should be sized as shown on the
refrigeration legend that is furnished for the store
or according to ASHRAE guidelines.
Note: If Koolgas defrost is used, the liquid line
will need to be increased two sizes larger inside
the merchandiser area. This is necessary to
ensure even liquid drainage from all evaporators
during defrost.
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.
