Low Temperature Merchandisers
UL LISTING
These merchandisers are manufactured to
meet ANSI/ UL 471 standard requirements for
safety. Proper installation is required to main-
tain the listing.
FEDERAL / STATE REGULATION
These merchandisers at the time they are man-
ufactured, meet all federal and state/ provincial
regulations. Proper installation is required to
ensure these standards are maintained. Near
the serial plate, each merchandiser carries a
label identifying the environment for which the
merchandiser was designed for use. A Type II
fan speed control kit is required for each mer-
chandiser to operate at Type II conditions.
ANSI/NSF-7 Type I – Display Refrigerator / Freezer
Intended for 75°F (24°C) / 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
temperature is maintained at or below the
ANSI/ NSF-7 specied 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 efciency. 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 TEMPERATURE
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 product life.
INSTALLATION
Merchandiser must operate for 24 hours
before loading product!
Regularly check merchandiser temperatures.
Do not break the cold chain. Keep products in
cooler or freezer before loading into merchandiser.
Medium temperature merchandisers are designed
for loading ONLY pre-chilled products.
Low temperature merchandisers are designed
for loading ONLY frozen products.
A 1.5inch (38 mm) space between the rear
of the merchandiser and wall must be main-
tained 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.
»Use caution when working around refrigeration
lines or water lines. Damage to equipment and/
or personal injury could occur.

Low Temperature Merchandisers
UNLOADING USING A PALLET JACK
A pallet jack is also very helpful in moving a
merchandiser to its permanent location. It can
also be used to remove optional casters or to
shim the case.
OPTIONAL CASTERS AND DOLLIES
Cases may be equipped with factory installed
casters or dollies. Instructions for removing
the casters or dollies are included in a separate
document, shipped with the case. Use caution
when transporting cases from the truck to the
store location.
SERIAL PLATE LOCATION
Serial plates are located on the left side, facing
the case. The serial plate contains information
about the specic model and its operating
parameters.
QR CODE
Insight cases have a QR code located on the
serial plate. Once you scan the QR code with a
smart phone, all of the information about that
case will be at your ngertips. Links to installation
videos, data sheets with case specications, the
installation and operation manual, as well as a
link to replacement parts from Hussmann’s
Performance Parts Website.
»Use caution when moving cases with casters

MERCHANDISERS SHIPPED
WITH END INSTALLED
If the merchandiser 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. Therefore, be
sure To replace These bolTs wiTh The shorTer
bolTs provided.NSF requires any bolt or screw
in the product area be capped or cut off if it
has more than three exposed threads.
Be careful not to damage the factory
installed end while moving the
merchandiser.
END SHIPPING BRACES
Move the merchandiser as close as possible to
its permanent location, then remove all packaging.
Check for damage before discarding packaging.
Remove all separately packed accessories such
as kits and shelves.
Do not remove end braces until joining begins.
Recycle wooden braces and hardware.
SHIPPING RIDER
Some merchandisers are shipped on a rider to
protect the factory installed front legs, and to
make positioning the merchandiser easier. To
remove the rider, remove bolts attaching rider to
each leg.
MERCHANDISER LEVELING
Merchandisers must be installed level to ensure
proper operation of the refrigeration system
and to ensure proper drainage of defrost water.
Pay close attention to case position during all
steps of setting, joining and leveling.
NOTE: Begin lineup leveling from the highest
point of the store floor.
Preparation
1. Using store blueprints, measure off and
mark on oor the exact dimensions/locations
of the merchandiser footprint. A 1½ inch space
is required behind each merchandiser to prevent
condensation.
2. Snap a chalk line for the front and rear
positions of the base pods.
3. Mark the location of each joint from front
to back lines.
4. use supplied shims To level case.Shims are to
be inserted under the black, plastic base pods.
»Do not remove shipping braces
until the merchandisers are
positioned for installation.

highest point of the oor by:
• Walking the oor and noticing any dips or
mounds;
• Using a string level; and
• Using a transit.
2. Position the rst merchandiser at the highest
point on the oor. Work outward from that
point to create the merchandiser lineup.
3. Use a 48 inch (1220mm) or longer level for
end-to-end leveling. The rear edge of the top
foam panel of the merchandiser is a good location
for the level at the rear of the case.
4. For leveling the merchandiser front-to-rear,
a 24 inch (610 mm) level should be placed on
the lower ange of the merchandiser end frame.
If the merchandiser has a factory installed end,
the level should be placed on the canopy support
brackets on top of the merchandiser. Suggested
level locations are shown in the illustration.

INSTALLING BUMPERS
1. Bumpers are packed out with the case and
snap onto the bumper retainer. Gaskets are
factory installed in the bumper retainers to provide
support for the bumpers. Do not remove the
gaskets.
2. Bumper joint inserts are provided with the
case to disguise joints for a lineup of cases.
3. Start at the left end of the lineup. Install 3ft
starter bumper rst. Refer to bumper side view
illustration to ensure the bumper is orientated
correctly. Place top of bumper over bumper
retainer, then snap bottom of bumper into place
at bottom of retainer. Position internal joint trim
between the starter bumper and full-length
bumper.
4. Continue installing bumper(s) until the
lineup is complete. The last piece of bumper
will need to be cut so that it is ush with the
right end cap. Use a ne tooth saw to cut the
bumper vertically at a 90° angle.
5. Ensure joint trim is positioned behind
bumper at all joints to close any gaps in the
lineup. Remove protective lm from bumper
once installation is complete.

Low Temperature Merchandisers
REFRIGERANT
The correct type of refrigerant will be stamped
on each merchandiser’s serial plate. The
merchandiser 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. When using high
glide refrigerants (e.g., R-407A, R-448A), if su-
perheat needs to be adjusted, use the evaporator
pressure and subtract the dew point from the coil
outlet refrigerant temperature to measure the su-
perheat level.
REFRIGERANT PIPING
Standard Case Connection Location
The refrigerant line connections are at the right
end of the merchandiser (as viewed from the
front) beneath the display pans. The installer
must saw a hole to exit the case. After connec-
tions have been made, thoroughly seal this
outlet. Seal both the inside and the outside.
It is recommended to use an expanding polyure-
thane foam insulation. Cover foam with silicone
to prevent water from entering foam.
Refrigerant lines must not interfere with the drain
covers. Drain covers must be removed to provide
access for cleaning.

When Dry
»Refrigeration lines are under pressure and should be de-
pressurized before attempting to make any connections.
»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 discharge 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.

Back Wall Piping Penetrations
Cases that are to be piped from the back have
a factory installed ¼ pilot hole in the exterior
liner. Use the pilot hole to locate the hole saw
to drill out a hole 2½ in. diameter hole to run
the coil piping.
After connections have been made, thoroughly
seal this outlet. Seal both the inside and the
outside.
It is recommended to use an expanding polyure-
thane foam insulation. Cover foam with silicone

Multiplexing
Piping of merchandisers operating on the same
refrigeration system may be run from mer-
chandiser to case. Do 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.
»When brazing pipes be sure to use the
insulation blanket shipped with the
merchandiser to prevent damage to the
foam bottom.
