exactly, a ﬁre or explosion may result, causing property

damage, personal injury or death.

Installation and service must be performed by a qualiﬁed

installer or service agency.

READ THE ENTIRE MANUAL BEFORE

INSTALLING OR USING THIS EQUIPMENT.

The unit uses R-290 gas as the refrigerant. R-290 is

ﬂammable and heavier than air. It collects ﬁrst in low

areas but can be circulated by the fans. If propane gas

is present or even suspected, do not allow untrained

personnel to attempt to ﬁnd the cause. The propane

gas used in the unit has no odor. The lack of smell does

not indicate a lack of escaped gas. If a leak is detected,

immediately evacuate all persons from the store, and

contact the local ﬁre department to advise them that

a propane leak has occurred. Do not let any persons

back into the store until the qualiﬁed service technician

has arrived and that technician advises that it is safe to

return to the store. No open ﬂames, cigarettes or other

possible sources of ignition should be used inside or in

the vicinity of the units.

NSF LISTING

These merchandisers are manufactured to meet

ANSI / UL 471 standard requirements for

safety. Proper installation is required to maintain

this listing. Near the serial plate, each case

carries a label identifying the type of conditions

for which the merchandiser was tested.

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

FEDERAL / STATE REGULATION

These merchandisers, at the time they are

manufactured, meet all federal and state /

provincial regulations.

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. VRL units take in air and

exhaust air through the front of the case. A

1-inch clearance space on top, at back or either

side of the case.

Recommended operating ambient

temperature is between

60°F (15.6°C) to 80°F (26.7°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.

VRL models have vented base panels to allow

air circulation through the condensing unit.

Allow for a minimum 36 in. clearance in the

front. Blocking or restricting air flow will

adversely affect performance and may damage

the refrigeration system.

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 the merchandiser 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 (if applicable). Lift crate from

the skid. Unscrew the case from the skid. The

merchandiser 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 merchandisers are to be set

to 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.

Case ventilation openings must be clear of any

obstructions. Do not damage the refrigerant

circuit.

Do not use mechanical devices or other means

to accelerate the defrosting process.

Do not use electrical appliances inside the food

storage compartments of the case.
