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

UL LISTING

These merchandisers are manufactured to

meet ANSI/ UL 471 standard requirements

for safety. Proper installation is required to

maintain the listing.

FEDERAL / STATE REGULATION

These merchandisers at the time they are

manufactured, 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 merchandiser 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

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) and 75°F (23.9°C).

Maximum relative humidity is 55%.

SELF CONTAINED (LOCATION)

NAV and NAVC merchandiser models have

front-facing condenserair intake and air

discharge. Maintain a minimum clearance

distance of 2 feet in front of the merchandiser

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 consid-

ered more of a ‘right to know’ law than a pure

product safety law. When used as designed, Huss-

mann 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. Service Deli Merchandisers

MODEL DESCRIPTION

NAV/C service deli merchandisers offer

versatility in the display of medium

temperature (32º F to 41º F) products such

as dairy products, prepared salads, pizza and

fresh dinners that are pre-chilled in a cooler.

Carefully read and follow the instructions

before 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, J-bar, Lever

Dolly, or Pry Lever.

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

merchandiser 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

procedure 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 stand or walk on top of

merchandiser. Do not store items or

ammable materials atop the unit.

MERCHANDISER LEVELING

Besure to position merchandisers

properly. 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 in the top interior at

the 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 maintain, service or order parts for the

merchandiser.

LIGHT SWITCH

The light switch is located at the rear of the

merchandiser. Ensure it is switched ON to turn

on the display lights.

Serial Plate
