Refrigerant
WARNINGS:
If the information in these instructions are not followed
exactly, a fire or explosion may result, causing property
damage, personal injury or death.
Installation and service must be performed by a qualified
installer or service agency.
READ THE ENTIRE MANUAL BEFORE
INSTALLING OR USING THIS EQUIPMENT.
The unit uses R-290 (propane) gas as the refrigerant.
R-290 (propane) is flammable and heavier than air. It
collects first in low areas but can be circulated by the
fans. If propane gas is present or even suspected, do not
allow untrained personnel to attempt to find the cause.
The propane gas used in the unit has no odor. The lack
of smell does not indicate a lack of escaped gas. If a
leak is detected, immediately evacuate all persons from
the store, and contact the local fire department to advise
them that a propane leak has occurred. Do not let any
persons back into the store until the qualified service
technician has arrived and that technician advises that it
is safe to return to the store. No open flames, cigarettes
or other possible sources of ignition should be used
inside or in the vicinity of the units.

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 TEMPERATURES
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
If a leak is detected, follow store safety proce-
dures. It is the store’s responsibility to have a
written safety procedure in place. The safety
procedure must comply with all applicable
codes such as local re department’s codes. At
minimum, the following actions are required:
• Immediately evacuate all persons from the
store, and contact the local re department to
advise them that a propane leak has occurred.
• Call Hussmann and/or a qualied service
agent and inform them that a propane sensor
has detected the presence of propane.
• Do not let any persons back into the store
until the qualied service technician has
arrived and that technician advises that it is
safe to return to the store.
• The propane gas used in the unit has no
odor. The lack of smell does not indicate a
lack of escaped gas.
• A hand-held propane leak detector
(“sniffer”) should be used before any repair
and/or maintenance is attempted. All repair
parts must be identical models to the ones
they are replacing.
• No open ames, cigarettes or other possible
sources of ignition should be used inside the
building where the units are located until
the qualied service technician and/or local
re department determines that all propane
has been cleared from the area and from the
refrigeration systems.
INSTALLATION
This equipment uses a ammable
refrigerant. Installation, service and
repair should be done only by qualied
and trained technicians in accordance
with this manual.

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.
A second serial plate for these multi-deck cases
is also located behind the return air grille in
the same location as singe-deck cases (shown
below).
QR CODE
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

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.
Do not remove shipping braces
until the merchandisers are
positioned for installation.

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 2 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.
Case Lineup Leveling
1. FLOORS ARE NOT LEVEL! The
whole lineup must be leveled on the same
plane, left to right and front to back. This
means that the entire lineup must be brought
up to the level of the highest case in the lineup.
Along the lines previously marked, nd the
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.
