appliance.

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.

• The 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.

• 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
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

• 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.

• 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.

• All casters on the appliance are lockable. After positioning the appliance in its nal
location, lock all casters.

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. 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 drawer handle when opening and
closing.

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