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 power switch or plug with
damp hands.

• Make sure the power switch is in the "OFF" position before plugging in or
unplugging the appliance to reduce the risk of electric shock.

• Before servicing, move the power switch to the "OFF" position. Unplug the
appliance from the electrical outlet.

• 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.

• 115VAC Models: THIS APPLIANCE MUST BE GROUNDED: This appliance
is equipped with a NEMA5-15 three-prong grounding plug
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 plug
and do not use an adapter plug. Failure to follow these instructions may result in
death, electric shock, or re.

• 208-230VAC Models: THIS APPLIANCE MUST BE GROUNDED: This appliance
is equipped with a NEMA L14-20 four-prong locking, grounding plug
the risk of potential shock hazards. It must be plugged into a properly grounded,
independent 4-prong wall outlet. If the outlet is a 3-prong outlet or a 4-prong
non-locking outlet, it is your personal responsibility to have a qualied electrician
replace it with a properly grounded, independent 4-prong locking wall outlet. Do
not remove the ground prong from the plug and do not use an adapter plug. After
plugging in, twist the plug clockwise to lock it into place. 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. Before unplugging a 4-prong plug, rotate the plug
counter-clockwise to unlock it.

• 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.

to reduce

• 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. Be careful when

WARNING, continued

• This appliance is designed only for 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 the cabinet air inlet or outlet, 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 place any product on the oor of the cabinet. All product must be placed on
properly installed shelves.

• 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.

• 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 the air outlet. They might freeze up and crack or break
causing a risk of injury or contamination of other food.

• To maintain proper product temperature on glass door models, allow at least 5"
(13cm) of space between items and LED light strips when lights are in use.

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. Blockage of
airow could negatively affect performance and damage the appliance.

• 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.
