WARNING

The 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 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
lifting or positioning. Work in pairs when
needed to prevent injury or damage.
Do not lift using the top section or the
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
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.

• THE APPLIANCE MUST BE
GROUNDED. The appliance is equipped

with a NEMA5-15 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 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.

• 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.

• The appliance is not intended for use by
persons (including children) with reduced
physical, sensory, or mental capabilities,
or lack of experience and knowledge,

could cause harm to individuals or
damage to the equipment.

• The 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.

• A minimum of 4" (11 cm) clearance is
required between the bottom of the
cooking equipment heating element
and the appliance top. When setting up
cooking equipment, follow the cooking
equipment manufacturer's setup
procedure. Temperature at the appliance
top must not exceed 180°F (82°C). For
optimum performance, installation of
a heat shield (supplied by others) is
recommended.

• Do not load any single drawer with more
than 75 lb. (34 kg) of product. Depending
on the weight of product in the drawers,
secure the unit as necessary to prevent it
from overturning. Do not open more than
one drawer at a time.

space between items to ensure good air
ow. Also allow space between items and
interior surfaces.

• Food storage and handling must comply
with applicable codes and regulations.

Let them cool rst, or they will raise the
cabinet temperature and could deteriorate
other foods in the cabinet or overload the
appliance.

• 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.
