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 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 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, prepa-

ration and display, the temperature of the

product 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 4 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 performance and may damage the refrig-

eration system.

Do NOT remove shipping crate until the

merchandiser is positioned

for installation.

Maintain minimum 4-inch

air clearance at rear of

case

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 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.

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.

DO NOT LAY MERCHANDISER OVER

ON THE FLOOR TO REMOVE SKID.

Check floor where cases are to be set to see if

it is a level area. Determine the highest part of

the floor.

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.

Do NOT stand or walk on top of

merchandiser. Do not store items or

ammable materials atop the unit.

SERIAL PLATE LOCATION

The serial plate is located on the back of the

case on the left-hand side. The serial plate con-

tains information specific to the case as well

as a QR code that allows you to view replace-

ment parts and data sheets on a smart phone.

REFRIGERATION UNIT ACCESS

Panels on the front and rear of the case may be

removed by lifting the panel straight upward

to clear lower brackets, and then down to

remove. The panel is installed by reversing the

above procedure. Ensure all panels are installed

to prevent air circulation problems.

The case is shipped with the the front left

panel removed, and the two lower back panels

removed. These panels must be installed during

installation.

GLASS POSITIONING

Check the following to improve opening or

closing of the merchandiser front glass.

1. Has the merchandiser been leveled

according to preceding paragraphs?

2. Is the glass handle installed correctly?

Verify the glass is bottomed out the length

of the handle. A bowed handle indicates the

glass may not be bottomed out at the center

of the handle.

The handle must be removed before it can be

repositioned. The handle is held in place with

silicone which must be completely removed

from the handle and the glass. Remove the

handle by pulling it away from the glass (do

not use tools to pry this loose). A damaged

or bent handle must be replaced. Apply new

silicone into the handle and firmly press onto

the glass.

3. Is the glass seated in the clamp hardware

correctly?

Verify glass is bottomed out in clamp

hardware. If the glass is not bottomed out in

the clamp hardware it can be re-positioned as

follows:

A. Remove the glass and clamp hardware

from the merchandiser by opening the

glass and loosening set screws in hinge

(Metric 3 millimeter set screws).

B. Slide the glass and clamp hardware to the

side out of the hinges and lay them on an

appropriate work surface.

Note: Adjacent glass must be closed.

C. Loosen the 8 set screws on the underside

of the clamp hardware.

D. Push the clamp hardware onto the glass

until bottomed out.

E. The clamp hardware must overhang the

glass by an equal amount on each side.

F. Tighten set-screws and re-install on

merchandiser. Apply a drop of Loctite

242 or equivalent thread locking uid onto

each set screw of the glass clamp assembly.

Tighten all screws with a TORX T15 bit and

re-install onto merchandiser.

IMPORTANT: Tighten all glass clamp set screws

to 26 inch lbs. Verify bit is in good condition and

not worn out. When set screws are tightened, glass

is rmly held in place by glass clamps.

4. Is the glass hitting the end or adjacent

glass? Slowly open and close the glass to

inspect. If the glass is hitting the end or

adjacent glass it may not be positioned

correctly from left to right. This can be

adjusted as follows:

• Loosen the 2 screws holding the hinge to

the clamp hardware (Metric 3 millimeter

screws).

• Slide the clamp hardware to either side as

needed.

• Tighten the screws and check glass for

proper operation.

5. Is the glass still hitting adjacent glass?

Slowly open and close the glass to inspect.

Optional Flexible Wiper Gasket

There may be an optional flexible wiper

gasket that is attached to each side. These

are designed to overlap each other, sealing

the gap between the glass and allowing side-

to-side glass adjustment. After all glass has

been adjusted as defined in Step 4, the flexible

portion of one gasket at a joint may be

trimmed with a razor knife. Be sure that the

remaining wiper gasket seals the gap. Verify

proper operation.

ADJUSTMENT BOLT

If the glass still does not open or close

correctly, adjustment of the top frame may be

necessary.

This merchandiser is equipped with an

adjustment bolt at the top rear of the

merchandiser to raise or lower the glass. This

allows for improvements in the glass operation

and sealing. The following outlines how to

access the adjustment bolt. The top must be

free to move as the adjustment bolt is turned.

1. Loosen joining or end bolts at top

of merchandiser, (2 at each end of

merchandiser).

2. If caulk or silicone has been applied

between merchandiser joints or ends in the

top area it must be removed.

3. Remove rear doors.
