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.

INSTALLATION

NSF LISTING

These merchandisers are manufactured to meet
ANSI / UL 471 standard requirements for
safety. Proper installation is required to maintain
this listing. Near the serial plate, each case
carries a label identifying the type of conditions
for which the merchandiser was tested.

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

FEDERAL / STATE REGULATION

These merchandisers, at the time they are
manufactured, meet all federal and state /
provincial regulations.

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 response to the
carrier for inspection within 15 days.

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%.

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.

Recommended operating ambient

temperature is between

60°F (15.6°C) to 80°F (26.7°C).

Maximum relative humidity is 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. VRM units in take air and

exhaust air through the front of the case, and
require no clearance space on top, at back or
either side.

SELF CONTAINED (LOCATION)

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.

Be sure to position self contained

merchandisers properly.

VRM models have vented base panels to allow
air circulation through the condensing unit.

Allow for a minimum 36 in. clearance in the
front. Blocking or restricting air flow will
adversely affect performance and may damage
the refrigeration system.

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.

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.

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.

Before Beginning Any Service or Repair:

Use a hand-held propane leak detector (“sniffer”)
to ensure no propane is present in the immediate
area, the inside of the display case and the inside
of the refrigeration system. R-290 is an odorless
refrigerant. Keep the area clear of all customers
and non- essential or unauthorized personnel.

Only Hussmann or factory
trained technicians should

Verify that all repair parts are identical models
to the ones they are replacing. Do not substitute
parts such as motors, switches, relays, heaters,
compressors, power supplies or solenoids. Failure
to do so can result in an explosion, death, injury
and property damage. Parts used on hydrocarbon
cases must meet specic UL certication for non­incendive or non-sparking components. Use only
Hussmann approved parts approved through the
Hussmann Performance Parts Website.

https://parts.hussmann.com/

Brazing must not begin before all propane has
been cleared from the immediate area — the
inside of the displays case and the inside of the
refrigeration system.

If a leak is detected, follow store safety
procedures. 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.

(propane) equipment.

Failure to follow
instructions can result in

• 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 flames, 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
