Important Safety Information

Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, damage to the appliance, or damage to property.

WARNING Indicates a hazardous situation which could result in death or

serious injury.

NOTICE Indicates a situation which could result in damage to the

appliance or property.

IMPORTANT Indicates important information about the use and care of the

appliance.

WARNING

This appliance should be destined only to the use for which it has been expressly
conceived. Any other use should be considered improper and therefore dangerous.
The manufacturer cannot be held responsible for injury or damage resulting
from improper, incorrect, and unreasonable use. Failure to install, operate, and
maintain the appliance in accordance with this manual will adversely affect safety,
performance, component life, and warranty coverage.

To reduce the risk of death, electric shock, serious injury, or re, follow basic
precautions including the following:

• Only qualied service technicians should install and service this appliance.

• This appliance must be installed in accordance with applicable national, state, and

local codes and regulations.

• To reduce the risk of electric shock, do not touch the plug with damp hands.

• Unplug the appliance before servicing.

• This appliance requires an independent power supply of proper capacity. See the

nameplate for electrical specications. Failure to use an independent power supply
of proper capacity can result in a tripped breaker, blown fuse, damage to existing
wiring, or component failure. This could lead to heat generation or re.

• THIS APPLIANCE MUST BE GROUNDED. This appliance is equipped with a

NEMA5-15 three-prong grounding plug to reduce the risk of potential shock
hazards. It must be plugged into a properly grounded, independent 3-prong wall
outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a
qualied electrician replace it with a properly grounded, independent 3-prong wall
outlet. Do not remove the ground prong from the power cord and do not use an
adapter plug. Failure to follow these instructions may result in death, electric shock,
or re.

• Do not use an extension cord.

• Do not use an appliance with a damaged power cord. The power cord should not

be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could
result in electric shock or re. To unplug the appliance, be sure to pull the plug, not
the cord, and do not jerk the cord.

WARNING, continued

• The GREEN ground wire in the factory-installed power cord is connected to the

appliance. If it becomes necessary to remove or replace the power cord, be sure to
connect the power cord's ground wire.

• Do not splash, pour, or spray water directly onto or into the appliance. This might

cause short circuit, electric shock, corrosion, or failure.

• Do not make any alterations to the appliance. Alterations could result in electric

shock, injury, re, or damage to the appliance.

• This appliance is not intended for use by persons (including children) with reduced

physical, sensory, or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.

• Children should be properly supervised around this appliance.

• Do not climb, stand, or hang on the appliance or door or allow children or animals

to do so. Do not climb into the appliance or allow children or animals to do so.
Death or serious injury could occur or the appliance could be damaged.

• Be careful not to pinch ngers when opening and closing the doors or rail cover

(prep table models). Be careful when opening and closing the doors or rail cover
when children are in the area.

• Open and close the doors and rail cover (prep table models) with care. Opening

the doors or rail cover too quickly or forcefully may cause injury or damage to the
appliance or surrounding equipment.

• Do not use combustible spray or place volatile or ammable substances in or near

the appliance. They might catch re.

• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance

could cause harm to individuals or damage to the equipment.

• Do not throw anything onto the shelves or load any single shelf with more than

120lb. (54.5 kg) of product. They might fall off and cause injury.

• This appliance is designed only for temporary storage of food. Employ sanitary

methods. Use for any other purposes (for example, storage of chemicals or
medical supplies such as vaccine and serum) could cause deterioration of stored
items.

• Do not block air inlets or outlets, otherwise cooling performance may be reduced.

• Do not tightly pack the cabinet. Allow some space between items to ensure good
air ow. Also allow space between items and interior surfaces.

• Do not put warm or hot foods in the cabinet. Let them cool rst, or they will raise

the cabinet temperature and could deteriorate other foods in the cabinet or
overload the appliance.

5

WARNING, continued

• All foods should be wrapped in plastic lm or stored in sealed containers. Otherwise

foods may dry up, pass their smells onto other foods, cause frost to develop, result
in poor appliance performance, or increase the likelihood of cross-contamination.
Certain dressings and food ingredients, if not stored in sealed containers, may
accelerate corrosion of the evaporator, resulting in failure.

• Do not store items near air outlets. Otherwise, items may freeze up and crack or

break causing a risk of injury or contamination of other food.

Additional Warnings for Prep Table Models

• The entire rail must always be covered by rail dividers and pans (1/6 size, up to

6"(15cm)deep). Otherwise, the appliance will not cool properly.

• Use only 1/6 size pans up to 6"(15cm) deep. Do not use damaged pans.

• Ingredients must be pre-chilled to 37°F (3°C) or less before placing in rail.

• Keep the rail cover closed when not actively preparing food.

• The rail is for keeping ingredients cool while preparing food. If not actively preparing

food for a long period such as overnight, seal pans with plastic wrap in addition
to closing the rail cover. Depending on conditions, the cabinet temperature
setting may need to be adjusted to prevent items from freezing. Alternatively, seal
ingredients and store them in a refrigerator or freezer.

NOTICE

• Protect the oor when moving the appliance to prevent damage to the oor.

• Keep ventilation openings, in the appliance enclosure or in the built-in structure,

clear of obstruction. Do not place anything on top of the appliance in an
undercounter installation. There must be at least 1.5" (4 cm) overhead clearance
for proper ventilation. The factory-installed rear bumpers must be in place to ensure

proper rear clearance. Blockage of airow could negatively affect performance and

damage the appliance.

• Do not allow the appliance to bear any outside weight.

• To prevent deformation or cracks, do not spray insecticide onto the plastic parts or

let them come into contact with oil.

• To avoid damage to the gasket, use only the door handle when opening and

closing.

• To avoid damage to the top seal, do not lift the appliance by the top panel or

remove the top panel.

Additional Notice for Prep Table Models

• Do not place anything on top of the rail hood or rail cover and do not lift the

appliance by the rail hood or rail cover. The rail hood and rail cover are not
designed to bear any outside weight.
