HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A. GSVM Open Vertical Merchandisers
UL LISTING
These merchandisers are manufactured to meet
ANSI/ UL 471 standard requirements for safe-
ty. Proper installation is required to maintain
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
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 cor-
rect 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
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%.
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.
INSTALLATION
Recommended operating ambient
temperature is between
65°F (18°C) to 80°F (26.6°C).
Maximum relative humidity is 55%.

P/N 0545716_G U.S. & Canada 1-800-922-1919 • Mexico 01 800-890-2900 • www.hussmann.com
SELF CONTAINED (LOCATION)
GSVM-4060 and GSVM-4072 (at 75°F/55%
relative humidity, maximum ambient conditions)
has front condenserair intake and discharge.
Maintain a minimum clearance distance of two
feet in front of the merchandiser so that air
discharge and air intake is not obstructed.
GSVM-4072 (at 80°F/55% relative humidity,
maximum ambient conditions) and
GSVM-5272 each require a 5 inch minimum
clearance behind the merchandiser and
clearance above the merchandiser since its air
flows straight through the condensing unit
compartment. Brackets are provided for field
attachment to obtain this rear 5 inch minimum
clearance.
For California Businesses:
This warning is the result of the California State
law known as the California Safe Drinking Water
and Toxic Enforcement Act of 1986, which is
commonly referred to as “Proposition 65.”
This warning does not mean that Hussmann
products will cause cancer or reproductive harm, or
is in violation of any product-safety standards or
requirements. As clarified by the California State
government, Proposition 65 can be considered more
of a ‘right to know’ law than a pure product safety
law. When used as designed, Hussmann believes
that our products are not harmful. We provide
the Proposition 65 warning to stay in compliance
with California State law. It is your responsibility
to provide accurate Proposition 65 warning labels
to your customers when necessary. For more
information on Proposition 65, please visit the
California State government website.

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A. GSVM Open Vertical Merchandisers
MODEL DESCRIPTION
The GSVM open vertical merchandiser offers
versatility in the display of medium temperature
(32º F to 41º F) products such as dairy products,
prepared salads, pizza and fresh entrees that
are pre-chilled in a cooler. Carefully read and
follow the instructions prior operating the mer-
chandiser.
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 merchandisers or
damage to the merchandisers and serious
personal injury could occur.
merchandisers are not structurally
designed to support 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.
Do not remove the shipping skid until the
merchandiser is near its final location. The
skid provides protection for both the merchan-
diser and the floor.
Remove the skid by raising one end of the
merchandiser approximately 6 inches. Block the
merchandiser securely, and remove the two skid
bolts from the raised end. Replace the bolts
with (provided) leg levelers. Repeat this proce-
dure at opposing end. Once the leg levelers are
secured in place, the merchandiser may be slid
off the skid and placed in its final location.
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.
Check floor where merchandisers are to be set
to see if it is a level area. Determine the highest
part of the floor.
Do not walk or put heavy objects on case.
Do NOT remove shipping crate until the
merchandiser is positioned
for installation.
Do NOT stand or walk on top of
merchandiser. Do not store items or
ammable materials atop the unit.

P/N 0545716_G U.S. & Canada 1-800-922-1919 • Mexico 01 800-890-2900 • www.hussmann.com
MERCHANDISER LEVELING
Besure to position merchandisers proper-
ly. Level the merchandiser by all four corners.
Merchandiser(s) must be installed level to
ensure proper operation of the refrigeration
system, and to ensure proper drainage of
defrost water.
OPTIONAL LEGS
NSF® approved legs replace the leg levelers if
required by local health codes. The legs raise
the case 6 inches for cleaning purposes. An
optional skirt kit can be provided to snap on
the legs.
SERIAL PLATE LOCATION
The serial plate is located on the interior top,
left side of the merchandiser. It contains all
pertinent information such as model, serial
number, amperage rating, refrigerant type and
charge. This information will be needed to install,
service or order parts for the merchandiser.
REFRIGERATION UNIT ACCESS
The lower front panel may be removed by
removing screw at bottom and lifting the panel
straight upward and over the tabs on which it
is hanging. The panel is installed by reversing the
above procedure.
Ensure lower front panel is flat against the
floor when installed to prevent air circulation
problems for self contained merchandisers.
Display is mounted on left
side of access panel. Be
careful not to detach cable
from display when removing
access panel.
SEALING MERCHANDISER TO FLOOR
If required by local sanitary codes, or if the
customer desires, merchandisers may be sealed
to the floor using a vinyl cove base trim. The
size needed will depend on how much variation
there is in the floor, from one end of the
merchandiser to the other. Sealing of the lower
front and rear panels on self contained models
may hamper their removal for servicing or
maintenance of the condensing unit.
NOTE: Do not allow trim to cover any intake
or discharge grilles located in the lower front
panel.

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A. GSVM Open Vertical Merchandisers
NIGHT CURTAIN INSTALLATION
Night curtains are used to cover the case opening
after normal business hours. The curtains
improve energy consumption, allowing the
refrigeration system to work less.
Carefully inspect the night curtain kit to
ensure there is no damage from breakage
during shipping. Case should be positioned
and leveled before installing the night curtain.
Position night curtain on top panel. Measure
21 inches to edge of the end night curtain.
Center night curtain to length of case.
Fasten night curtain to top panel using (3) #8
x 1/2 in. screws.
Night Curtain
The night curtain for GSVM is standard
for model 5272 and is an optional kit for
models 4060 and 4072.
