CERTIFICATION
These merchandisers are manufactured to
meet ANSI / National Sanitation Foundation
(NSF®) Standard #7 requirements. Proper
installation is required to maintain certification.
Near the serial plate, each case carries a label
identifying the type of application for which
the case was certified.
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
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
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 75°F (23.9°C).
Maximum relative humidity is 55%.

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.
Besure to position self contained
merchandisers properly.
HGM-TS Location
The condensing unit is located at the top of
the HGM-TS. At least 12 inches of clearance
should be allowed at the rear of the cabinet and
at the top of the merchandiser. This clearance is
necessary to provide free air movement to and
from the condensing unit for maximum
operating efficiency.
This product may contain chemicals known
to the State of California to cause cancer,
birth defects, or other reproductive harm.
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 claried 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. HGM Merchandisers
HGM-BS Location
At least 24 inches of clearance should be
maintained in front of HGM-BS merchandisers
and 6 inches of clearance at the rear to provide
the necessary free air movement to and from
the condensing unit. The condensing unit is
located at the bottom of these merchandiser.
HGM-2BS merchandisers require the same
clearance space, but the air flow is different
as shown in the illustration at right. Avoid
installing 1-door merchandisers on the left side
of the case.

MODEL DESCRIPTION
The HGM-BS/TS models are self-contained,
medium temperature, vertical glass door
merchandisers designed for the display of dairy
products, deli items and beverages. Design
features include self-closing glass doors,
efficient foamed in place non-CFC insulation
and balanced R-134a refrigeration systems for
energy saving performance.
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 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. Lift crate from the skid.
Unscrew the case from the skid. The fixture
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.
Tilting merchandiser could cause damage to
the refrigeration system.
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 cases are to be set to see if
it is a level area. Determine the highest part of
the floor.
Unpack door and all packaged accessories.
Do NOT remove shipping crate until the
merchandiser is positioned
for installation.
Do not store objects or ammable
materials atop the unit.
