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 gas as the refrigerant. R-290 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.

HUSSMANN PRODUCT CONTROL
The serial number and shipping date of all
equipment is recorded in Hussmann’s files
for warranty and replacement part purposes.
All correspondence pertaining to warranty or
parts ordering must include the serial number
of each piece of equipment involved. This is
to ensure the customer is provided with the
correct parts.
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

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 merchandisers
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
merchandiser.
Recommended operating ambient
temperature is between
60°F (15.6°C) to 80°F (26.7°C).

UNLOADING
Unloading from Trailer:
Lever Bar (also known as a Mule, Johnson
Bar, J-Bar, Lever Dolly, or Pry Lever)
Move the merchandiser as close as possible
to its permanent location and remove
all packaging. Check for damage before
discarding packaging. Remove all separately
packed accessories such as kits and shelves.
Improper handling may cause damage to
the merchandiser when unloading. To avoid
damage:
1. Do not drag the merchandiser out of the
trailer. Use a Johnson bar (Mule).
2. Use a forklift or dolly to remove the
merchandiser from the trailer.
EXTERIOR LOADING
Do NOT walk on top of the merchandiser or
damage to the merchandisers and serious
personal injury could occur.
merchandisers are not structurally
designed to support excessive external
loading such as the weight of a person.
Do not place heavy objects on the
merchandiser.
SHIPPING SKID
Each merchandiser is shipped on a skid to
protect the merchandiser’s base and to make
positioning the case easier.
Remove the top of the crate and detach walls
from each other (if applicable). Lift crate from
the skid. Unscrew the case from the skid. The
merchandiser can now be lifted off the crate
skid. Lift only at base of skid! Remove any
braces and/or skids attached (blanket wrapped
merchandiser may have skids).
DO NOT TILT MERCHANDISER ON ITS
SIDE OR END WHEN REMOVING SKID.
Once the skid is removed, the merchandiser
must be lifted —NOT PUSHED— to
reposition. To remove the skid, remove screws
attaching skid to the merchandiser.
Check floor where merchandisers are to be set
to if it is a level area. Determine the highest
part of the floor.
Do NOT stand or walk on top of
merchandiser. Do not store items or
ammable materials atop the unit.
Case ventilation openings must be clear of any
obstructions. Do not damage the refrigerant
circuit.
Do not use mechanical devices or other means
to accelerate the defrosting process.
Do not use electrical appliances inside the food
storage compartments of the case.
