ELECTRICAL CONNECTION
Improper use of the grounded plug can result in the risk of electrical shock.
If the power cord is damaged, frayed or shows cracks or abrasions across
its length, have it replaced at an authorized service center.
For your protection, this unit is equipped with a 3-conductor cord set that has a molded 3-prong
grounding-type plug, and should be used in combination with a properly connected grounding-type
outlet.
Do not under any circumstances cut or remove the third ground prong from the power cord
supplied. For personal safety, this appliance must be properly grounded.
The cord should be secured behind the unit and not left exposed or dangling to prevent
accidental injury.
A standard electrical supply (115V AC - 60Hz), properly grounded in accordance with the
National Electrical Code and local codes and ordinances, is required.
When a standard 2-pin wall outlet is encountered, it is your responsibility to have it replaced
with a properly grounded 3-pin wall outlet.
Never unplug the unit by pulling the power cord. To disconnect the appliance, always grip the

INSTALLATION
BEFORE USING YOUR APPLIANCE
Remove all packing material before using your appliance.
IMPORTANT: Before connecting the unit to a power source, let it stand upright for approximately
24 hours. This will reduce the possibility of a malfunction in the cooling system from handling
during transportation.
Clean the interior surface with lukewarm water and a soft cloth.
INSTALLATION OF YOUR APPLIANCE
Position the unit in a dry and well-ventilated place. Avoid placing the cooler near any source of
heat or moisture, or in direct sunlight. Do NOT install the unit in a location with an ambient
temperature that will fall below 60°F.
For freestanding installation, 5” of space at the back and both sides are suggested to ensure
proper air circulation to cool the compressor and condenser.
For built-in installation, leave a ¼” (6.35mm) space on each side and at the top, and 1-2” at the
back of the wine cooler to ensure proper air circulation to cool the compressor and condenser.
Also, be sure to not obstruct the front exhaust vent with anything as this may prevent the unit from
performing properly.
Place the appliance on a level surface strong enough to support it when it is fully loaded. To
level the wine cooler, adjust the front leveling legs at the bottom of the unit.
For best performance it is recommended that you install the appliance in a location with an
ambient temperature between 60°-90°F. If the ambient temperature is above or below
recommended temperatures, the performance of the unit may be affected.
It is recommended that you do not install the appliance near an oven, radiator or other heating
source. Direct sunlight may affect the acrylic coating and heat sources may increase electrical
consumption. Don’t install in a location where the temperature will fall below 60°F.
Do not store or install the appliance outdoors, in a garage, basement, or in moist areas.
Plug the unit into an exclusive, properly installed-grounded wall outlet.
Do not lift unit by the door handle.
To level your appliance, adjust the front legs at the bottom of the appliance.
INSTALLING THE HANDLE
The stainless steel handle should be installed according to the following diagram:

KEY LOCK
If 2 minutes pass without any keys being selected, the controls will lock automatically. To release the
lock, touch the
and marks at the same time for at least 5 seconds.
TEMPERATURE ZONES
The wine cooler has two temperature zones with a temperature range of 40°-72°F. The recommended
temperature setting for each zone is:
Lower Zone between 40°-72°F
Upper Zone between 40°72°F
NOTE: The temperature set for the Lower Zone must always be the same or higher than the
temperature set for the Upper Zone. For optimal performance, the set temperature of the two
zones should differ by at least 4°F.
SETTING A TEMPERATURE
The temperature will increase by 1°C or 1ºF if you touch UP
once, or the temperature will
decrease by 1°C or 1ºF if you touch DOWN
once.
To view the set temperature in either zone at any time, touch UP
or DOWN
and the set
temperature will temporarily flash in the LED display for 5 seconds.
NOTE: When using the unit for the first time or after a long period of inactivity, there may be a
variance of a few degrees between the selected temperature and the temperature indicated on the
LED readout. This is normal due to the length of inactivity, and will correct itself after the unit runs for
a few hours. If the unit is unplugged, has lost power or is turned off, wait 3 to 5 minutes before
restarting the unit. The unit will not restart before this time delay.

DYNAMIC COOLING/SILENT MODES
The Dynamic Cooling feature enables the relative humidity inside the unit and the temperature to be
distributed evenly around the interior so you can store all of your wine under the exact same ideal
conditions. If you would like to use the unit to store wine long term, the dynamic cooling is a must.
This will create a continuous climate in the cabinet which imitates that of a wine cellar.
In the Dynamic cooling mode, the interior fan circulates the inside air evenly until the set temperature
is reached. Dynamic Cooling is the factory preset mode. To change to Silent mode, touch and hold
the UP button for approximately five seconds. The wine cooler will beep three times to confirm silent
mode is on. To change back to Dynamic Cooling mode, touch and hold the DOWN button for five
seconds. The wine cooler will beep five times to confirm Dynamic Cooling mode is on.
STORING WINE
While bottles may vary in size and dimension, you can store approximately 21 standard Bordeaux 750
ml bottles in the lower zone and 24 8-12oz cans in the upper zone. Please note that bottle capacities
are approximate maximums when storing traditional Bordeaux 750 ML bottles and include bulk
storage.

CARE AND MAINTENANCE
CLEANING YOUR WINE COOLER
IMPORTANT: Always unplug the unit before cleaning or performing maintenance. Never use harsh
cleansers or scouring pads to clean any part of the unit.
Turn off the power, unplug the appliance, and remove all items including shelves.
Wash the inside surfaces with a warm water and baking soda solution. The solution should be
about 2 tablespoons of baking soda to a quart of water.
Wash the shelves with a mild detergent solution.
Wring excess water out of the sponge or cloth before cleaning control panels or any electrical
parts.
Wash the outside cabinet with warm water and mild liquid detergent. Rinse well and wipe dry
with a clean soft cloth.
Draw out the water box at the bottom and wash with a mild detergent solution.
Do not connect or disconnect the electric plug when your hands are wet.
Never clean appliance parts with flammable fluids. These fumes can create a fire hazard or
explosion.
Do not use solvent-based cleaning agents or abrasives on the interior. These cleaners may
damage or discolor the interior.
DEFROSTING
The unit defrosts automatically.
The evaporator behind the rear wall of the unit defrosts automatically. The condensate
collects in the drainage channel behind the rear wall of the unit and flows through the
drainage hole into the drip tray by the compressor where it evaporates.
POWER FAILURE
Most power failures are corrected within a few hours and should not affect the temperature of your
appliance if you minimize the number of times the door is opened. If the power is off for an extended
period of time, proper steps should be taken to protect your contents.
INACTIVITY
If the unit will not be used for a period of less than three weeks, leave the cooler operating. If the
period of inactivity is several months, remove all items and turn the unit off. Clean and dry the interior
thoroughly. Leave the door open slightly to prevent any possible moisture build-up.
MOVING YOUR WINE COOLER
Before moving your cooler, first be sure to remove all items from the cooler.
Always unplug the cooler before moving.
Use two or more people to move and install the appliance. Failure to do so can result in back or
other injuries.
Securely tape down any loose items, such as shelves, inside the unit.
Turn the adjustable leg up to the base to avoid damage.
Tape the door shut.
Ensure that the unit stays securely in the upright position during transportation. Protect the
outside of the appliance with a blanket or similar item.

ENERGY SAVING TIPS
The unit should be located in the coolest area of the room away from heat sources or direct
sunlight.
Ensure that the unit has proper allowances on all sides for proper ventilation. Never cover any
air vents.
Only open the cooler door for as long as necessary. Frequent opening of the door will affect
internal temperature.
