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.
• Wear appropriate personal protective equipment (PPE) when servicing the
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.
• 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 plug 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.

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.
• This unit must be installed and located appropriately, following the
installation instructions before its use.

CHECK FOR SHIPPING DAMAGE
Prior to leaving the factory, each cabinet is throughly inspected and
performance tested to assure proper operating temperatures.
Check the crate thoroughly for signs of shipping damage. If external
damage exists, internal damage is also probable. Uncrating should be done
while the carrier´s representative is present. Otherwise, the equipment
should be uncrated as soon as possible, preferably within ve (5) days.
The manufacturer is not responsible for in-transit damage and the consignee
must le any required damage claims directly with the carrier.
If the damage is severe and obvious, write a brief description of the evidence
on the carrier’s delivery receipt, and above the carrier representative’s
signature. Call the distributor or dealer immediately, indicating that the
cabinet was damaged.
DANGER: Risk of Fire or Explosion due to Flammable Refrigerant Used.
Follow Handling Instructions Carefully in Compliance with U.S.Government
Regulations.
If no obvious crate damage is present, within two hours of receiving the
cabinet from the carrier, remove the packaging to inspect for concealed
damage.
1. If concealed damage is found, call the carrier immediately, save all
crating materials, and le the necessary freight claim with the carrier.
Check for accesories: Check that the shelves are inside the refrigerator,
including the four clips or supports for each shelf.
WARNING
• This appliance must be installed in accordance with all applicable
national, state, and local regulations.
• Appliance is heavy. Use care when lifting or positioning. Work in
pairs when needed to prevent injury or damage.

LOCATION
Select location
This appliance is approved for indoor or outdoor use. The proper
location will ensure peak performance of your appliance. We
recommend a location where the unit will be out of direct sunlight
and away from heat sources. To ensure your product performs to
specications, the recommended installation location temperature
range is from 55°F to 115°F (13°C to 46°C).
Cabinet clearance
Ventilation is required from the bottom front of the appliance. Keep
this area open and clear of any obstructions. Adjacent cabinets and
counter top can be installed around the appliance as long as the
front grille remains unobstructed.
Front Grille
Do not obstruct the front grille. The openings within the front grille
allow air to ow through the condenser heat exchanger. Restrictions
to this air ow will result in increased energy usage and loss of
cooling capacity. For this reason it is important this area not be
obstructed and the grille openings kept clean. It is not recommend
the use of a custom made grille as air ow may be restricted.
HANDLING THE CABINET

11
The base of the refrigerator has heavy duty leveling legs underneath so the
cabinet may be leveled appropriately and to allow room to clean beneath
the cabinet.
Level the cabinet front to back and side to side with a level by using the
adjustable portion of the leveling legs.
