upright for at least 24 hours to allow the compressor’s oils to settle.
Unpacking the Wine Refrigerator
Types of Installation
This wine refrigerator has been designed for free-standing or built-in installation. In each case,
there must be adequate ventilation and access for service.
Free-standing Installation:
A free-standing installation will allow you to install the wine refrigerator in almost any place
you desire. You must follow the stated instructions for electrical requirements and leveling
the wine refrigerator.
Built-in Installation:
A recessed installation will allow you to install the wine refrigerator under a counter or in a
kitchen cabinet as long as the required clearance space around the wine refrigerator is
provided. It is necessary to allow adequate ventilation space around the unit, including at
the back of the unit. The following additional items must be observed:
1. Place the wine refrigerator in front of the installation location. Adjust the feet and
place the unit flat on the floor or on a platform depending on your installation
requirements.
2. If the electrical outlet for the wine refrigerator is behind the cabinet, plug in the wine
refrigerator.
3. Push the wine refrigerator into position.
Warning: DO NOT install the wine refrigerator behind a closed cabinet door.

Important Notes:
•Choose a location that has ambient temperatures above 50° F and below 95° F. Operation outside
these temperatures may result in lowered efficiency or cause other adverse effects.
•This unit MUST be installed in an area protected from the elements, e.g. wind, rain, water spray or
drips.
•The wine refrigerator should not be located next to ovens, grills, or other high heat sources.
•Do not kink or pinch the power supply cord between the wine refrigerator and the wall or cabinet.
Installation Clearance Requirements
When installing the wine refrigerator under a counter, follow the recommended spacing
dimensions shown.
•To ensure proper service access and ventilation, allow at least 1-2” of clearance at the
back, 1/4” at the top, and 1/4” at the sides. If the door side is against a wall, allow at least 2
3/8”of clearance. The installation should allow the unit to be pulled forward for servicing, if
necessary.
•The wine refrigerator should be installed on a firm and level surface that will be able to
support the entire weight of a fully loaded unit. It is important for the wine refrigerator to be
level in order to work properly. If needed, you can adjust the height of the wine refrigerator
by rotating the feet. See the “Leveling the Wine refrigerator” section.
•A standard electrical supply (115 VAC only, 60 Hz), properly grounded in accordance with
National Electrical Code and local codes and ordinances, is required.

Electrical Requirements
Before you move your wine refrigerator into its final location, it is important to make sure you
have the proper electrical connection:
A standard electrical supply (115 V, 60Hz), properly grounded in accordance with the National
Electrical Code and local codes and ordinances, is required.
It is recommended that a separate circuit, serving only your wine refrigerator, be provided. Use
receptacles that cannot be turned off by a switch or pull chain.
The fuse (or circuit breaker) size should be 15 Amps.
Recommended Grounding Method
For your personal safety, this appliance must be grounded. It is equipped with a power
supply cord that has a 3-pronged grounding plug. To minimize possible shock hazard, the
cord must be plugged into a mating 3-pronged wall socket, and grounded in accordance
with the National Electrical Code and local codes and ordinances. If a mating wall socket is
not available, it is the personal responsibility of the customer to have a properly grounded,
3-prong wall receptacle installed by a qualified electrician.
Leveling the Wine refrigerator
It is important for the wine refrigerator to be level in order to work
properly. It can be raised or lowered by rotating the plastic sheaths
around each of the feet on the bottom of the machine. If you find that the
surface is not level, rotate the feet until the wine refrigerator becomes
level .You may need to make several adjustments to level it. We
recommend using a carpenter’s level to check the machine.
1. Place a carpenter’s level on top of the product to see if the wine
refrigerator is level from front to back and side to side.
2. Adjust the height of the feet as follows:
Turn the leveling feet to the right to lower that side of the
refrigerator.
Turn the leveling feet to the left to raise that side of the refrigerator.
