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

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 exam-

ined 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 rela-

tive 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 prop-

temperature. This means that from the time

the product is received, through storage, prepa-

ration and display, the temperature of the prod-

uct must be controlled to maximize the life of the

product.

Besure to position self contained

merchandisers properly.

SELF CONTAINED models have vented base

panels to allow air circulation through the

condensing unit.

Allow for a minimum 5 in. clearance from

walls, merchandisers, and any other large

objects near the merchandiser’s vented base

panels (for self contained models). Blocking

or restricting air flow will adversely affect per-

formance and may damage the refrigeration

system.

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. MD Open Vertical Merchandisers

MODEL DESCRIPTION

The MD models are open, vertical, medium

temperature display merchandisers. They are

self contained merchandisers with their own

condensing unit. Each self contained model

has a condensing unit that is factory installed

beneath the display area of the case. The unit

is ready for operation when electrical service is

connected.

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 dam-

age:

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.

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.

Do NOT remove shipping crate until the

merchandiser is positioned

for installation.

Do not store items or ammable materials

atop the unit.

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.

SERIAL PLATE LOCATION

The serial plate is located at the interior top

left end. It contains all pertinent information

such as model, serial number, amperage rating,

refrigerant type and charge.

REFRIGERATION UNIT ACCESS

The lower front panel may be removed by

lifting the panel straight upward and over

the tabs on which it is hanging. In a self con-

tained merchandiser, two screws will have to

be removed from either end of the panel. The

panel is installed by reversing the above proce-

dure. Ensure lower front panel is flat against

the floor when installed to prevent air circula-

tion problems on self contained merchandisers.

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 varia-

tion 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 mod-

els 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.
