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 qualied service technicians should
install and service the appliance.
• Wear appropriate personal protective
equipment (PPE) when servicing the
appliance.
• The appliance must be installed in
accordance with applicable national, state,
and local codes and regulations.
• Appliance is heavy. Use care when

needed to prevent injury or damage. Do
not lift using the top section or the doors/
drawers.
• To reduce the risk of electric shock, do not
touch the plug with damp hands.
• Unplug the appliance before servicing.
• The appliance requires an independent
power supply of proper capacity. See the
nameplate for electrical specications.
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.
• THE APPLIANCE MUST BE
GROUNDED. The appliance is equipped
with a NEMA5-15 three-prong grounding
plug
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 qualied 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.

around the appliance.
• Do not climb, stand, or hang on the
appliance or doors/drawers 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/drawers
or rail cover (prep table models) or when
handling food pans. Be careful when
opening and closing the doors/drawers or
rail cover when children are in the area.
• Open and close the doors/drawers and
rail cover with care. Opening the doors/

cabinet temperature and could deteriorate
other foods in the cabinet or overload the
appliance.
• Food storage and handling must comply
with applicable codes and regulations.
• 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.
• Do not throw anything onto the shelves or
load any single shelf with more than 120lb.
(54.5 kg) of product. They might fall off and

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.
