LOCATION
These merchandisers 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 merchandisers in direct sunlight, 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 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.
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.

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
product area. T
HEREFORE, BE SURE TO REPLACE
THESE BOLTS WITH THE SHORTER BOLTS PROVIDED
.
NOTE:
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 merchandiser 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.
LEVELING
Merchandisers must be installed level to ensure
proper operation of the refrigeration system and to
ensure proper drainage of defrost water. Ice may
build up from defrost water not draining out of
merchandiser if merchandiser is not leveled.
When leveling merchandisers, use a carpenter’s
level as shown. Leveling shims are provided with
each merchandiser 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 merchandiser. If a gap
exists between the support rail of the merchandiser
and the floor, a shim should be placed in the center.
Do NOT remove shipping braces until the
merchandisers are positioned
for installation.
NOTE: Do not place levels
on Display Pans or
on Shelves.

SPLASHGUARD BRACKET AND JOINT SUPPORT
Install Splashguard Bracket
Position splashguard brackets to the merchandiser
and level to the floor. Each bracket has a 1
1
/2 in.
(38 mm) slot at the rear of the bracket where it
attaches to the merchandiser. Tighten screws to
secure the brackets.
Install Splashguard Joint Support
Position the joint support across the brackets as
shown above. Fasten with hex head sheet metal
screws.
OFFSETTING BUMPERS AND TOP RAIL
Offsetting the bumpers and glass trim helps to
disguise the joint locations, giving the lineup a
smoother look.
1. Locate 2 ft (610 mm) starter bumpers and glass
trim. They are shipped with the left-end kit.
2. Remove factory installed glass trim and
bumpers from cases as follows:
a
. Standard plastic glass trim is friction fit.
Start at left end and lift up, moving to right
end. Pry tools will damage trim.
b. Remove upper and lower bumpers by
pulling bumper away from bumper retainers. Be careful not to misplace the internal
joint trims from 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.
b. Install full length bumpers and internal
trims offset across joints. Make sure that
no gaps exist between sections. Continue
installing the upper bumpers the length of

Trying to re-install only the popped part may not
secure the trim, and may damage the trim.
8. Once all except the last sections of upper
bumper and glass trim have been installed,
refrigerate the case line up for at least six (6)
hours. The last sections of upper bumper
and glass trim should be kept inside a
refrigerated case or cooler during this time
to allow the bumpers and trim to contract.
9. Go to right end of case line up and tap glass
trim and bumpers to close any gaps.
10. Measure and cut last section of bumpers and
glass trim. Use a miter box and fine-tooth saw
to cut last bumpers and glass trim to length.

REFRIGERANT
The correct type of refrigerant will be stamped
on each merchandiser’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 righthand 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 merchandiser to merchandiser. D
O NOT 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 merchandiser
must be located as shown below to allow room for
lifting the hinged fan plenums and for clearance
beneath the display pans. Or the interconnecting
piping may be run outside the case in the raceway
area shown.
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
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.
REFRIGERATION / ELECTRICAL
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 damage to the
plastic case bottom.

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 wherever condensation drippage is objectionable or the 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 evaporator take-off.
(Minimum 3 in. (76 mm) loop.)
REFRIGERATION THERMOSTAT
The bulb for the optional refrigeration thermostat
is located approximately 12 in. (305 mm) above
the coil and 6 ft (1829 mm) from the left-hand end
(facing front) of the merchandiser. The optional
refrigeration thermostat is located 5 ft (1524 mm)
from the left-hand end, just past the raceway. On
wide island models, the thermostat body is located
on the serial plate side (front) of the merchandiser.
DEFROST TERMINATION THERMOSTAT
The standard disc type defrost termination
thermostat is not adjustable. This thermostat is
clamped to the suction line of the coil on the
left-hand (facing front) end of the merchandiser.
DEFROST SEQUENCES
The Time Clock initiates defrost. The evaporator
fans continue to circulate air across the evaporator
coil, melting any frost build-up. Defrost can be
terminated by either temperature or time.
Temperature Termination
Temperature termination should be used for the
following types of installations:
1. Parallel systems with EPRs or suction stop
solenoids
2. Single compressor units without pump-down
cycle.
Time Termination
Time termination should be used for the following
types of installations:
1. Parallel systems with thermostat and liquid
solenoid.
2. Single compressor units with pump-down.
To use time termination, simply do not wire the
termination thermostat.

WASTE OUTLET AND WATER SEAL
The waste outlet is located in front of the fan
plenum 6 ft (1829 mm) from the left-hand end of
8 ft (2438 mm) and 12 ft (3658 mm) merchandisers (facing case front). The waste outlet is located
in the center of 4 ft (1219 mm) and 6 ft (1829 mm)
merchandisers. A water seal is supplied with each
fixture. The water seal must be installed to the
waste outlet to prevent air leakage and insect
entrance into the fixture.
NOTE:
Water seal outlet must clear front skid rail.
A tee, adapter, plug and street ell are also supplied
with each merchandiser.
INSTALLING DRIP PIPING
Poorly or improperly installed drip pipes can
seriously interfere with the merchandiser’s operation and result in costly maintenance and product
losses. Please follow the recommendations listed
below when installing drip piping to ensure good
drainage.
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. D
OUBLE 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 in. per
foot (4 mm per 305 mm).
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 drip pipes from freezing:
A. Do NOT install drip pipes in contact with
uninsulated 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.
Splashguard brackets MUST be installed
before piping case.

MULTI-DECK SHELF ALIGNMENT
Taped to one of the shelves in each merchandiser
is a small plastic bag containing shelf alignment
strips. These strips are designed to enhance the
appearance of the shelves by aligning the front
edge of each shelf with that of an adjacent shelf.
When installing shelves:
1. Insert one of the alignment strips into the slot
behind the front edge of each shelf.
2. After all shelves are installed, slide the strip
across the shelf joint wherever two shelves are
adjacent. This will lock them together.
NOTE: Some price tag molding styles are pop riveted to the shelf. In these instances, the alignment
strips must be cut in half before insertion.
MULTI-DECK SHELF CONFIGURATION
The bottom display shelves can be adjusted to
accommodate shallow or volume displays
(bulky items such as hams or chickens). The
upper shelves are individually adjusted in 1 in.
(25 mm) increments and have two-position
brackets permitting shelves to be placed in a flat or
down-tilt position (see illustration). Front product
stops are recommended when shelves are placed in
the down-tilt position.
Lighted shelves do not work in
low temperature applications.
