SELF CONTAINED LOCATION

Product should always be maintained at proper

temperature. This means that from the time

the product is received, through storage, prepa-

ration and display, the temperature of the

product must be controlled to maximize the

life of the product.

Self contained models have vented base panels

to allow air circulation through the condensing

unit.

See illustrations for clearances distances from

walls, merchandisers, and any other large

objects near the merchandiser’s vented base

panels. Blocking or restricting air flow will

adversely affect performance and may damage

the refrigeration system.

These models need clearance a minimum of 1

inch on each side and at the back of the unit.

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 safetylaw.

products are notharmful. 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,

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A. SHM-A Merchandisers

MODEL DESCRIPTION

SHM-A merchandisers offer versatility for the

display of food items such as: fresh fruit,

vegetables, cheeses and other delicatessen

items. Carefully read and follow the instruc-

tions prior to operating the merchandiser.

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. Do not stand

inside of 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 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.

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 leg levelers can be

provided for this purpose.

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 left

wall of the merchandiser. It contains all perti-

nent 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 access panel may be removed by

lifting the panel straight upward and over the

screws on which it is hanging. The panel is

installed by reversing the above procedure.

Ensure lower access panel is flat against the

floor when installed to prevent air circulation

problems on 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 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.
