INSTALLATION CHECKLIST
To ensure a proper installation, this checklist should be completed to ensure that no part of the process has
been overlooked.
Has the electrical circuit been verified of using a dedicated 15-amp circuit with the ground plug attached
and correct polarity. Discrepancies in the supplied power can cause serious damage and potentially void
all warranty. Please see page (5) for a more detailed description of electrical guidelines.
Have all the packaging materials been removed? NOTE: please make sure the toe kick which is taped to
the back of the unit is removed prior to pushing the unit in place.
Have the anti-tip brackets been installed securely and are they properly engaging the unit? NOTE: the
location of the anti-tip brackets is taped within the toe kick packaging. For installation instructions please
see page (9).
Is the unit leveled properly with all leveling legs making contact with the floor? Has the toe kick been
installed? Proper leveling should be done from the inside of the unit rather than the top exterior of the unit.
Has the door stop been installed?
Has the customer been given the installation / user guide? NOTE: A lock is standard on stainless steel
units, therefore the key to the lock is taped to the back of the user/install guide. Overlay paneled units will
not come with a lock or key.
Have stainless steel surfaces been inspected for any imperfections? This is to be done by the authorized
True dealer or installer with the customer, upon completion of installation. Stainless steel doors, handles
and shelves are covered by limited 30-day warranty for cosmetic defects.
Is the unit operating properly? If not, is the unit plugged in? Is the breaker on? Is the display illuminated
and say “off”? For all control operations and sequences please refer to “user interface commands on True
Precision control” section in the table of contents per the model of the unit you are installing.
Does the customer understand the unit’s operation?
Make sure the unit is operating and cooling for 24 hours prior to loading with product. NOTE: loading the
unit with some bottles of water will provide assurance the unit is working properly during this 24-hour
time-frame.
Verify all the shelves are securely in place.
Has the Dual Zone wine unit been connected to an external alarm system? Refer to page (6)

DATA TAG INFORMATION
Data tags are located on the interior upper left hand wall. The serial # is the method we track all pertinent
information for the unit.
SAFETY PRECAUTIONS
• This refrigerator must be properly installed and located in accordance with the installation instructions
before it is used.
• Do not allow children to climb, stand or hang on the shelves in the refrigerator. They could damage the
refrigerator and seriously injure themselves.
• Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other
appliance.
• Keep hands away from the “pinch point” areas (gaps between the doors and between the doors and
cabinet) small areas are not necessarily safe.
• Unplug the refrigerator before cleaning and making repairs.
NOTE: WE STRONGLY RECOMMEND THAT ALL SERVICING BE PERFORMED BY A QUALIFIED
INDIVIDUAL.
• Setting temperature control to OFF only removes power from the refrigeration system, it does not remove
power from other circuits. For example, temperature control board and lights.

15 & 24 INCH SERVICE MANUAL
ELECTRICAL SPECIFICATIONS
Do not, under any circumstances, cut or remove the third (ground) prong from the power cord. For personal
safety, this appliance must be properly grounded.
To minimize the depth of the cutout opening, the electrical outlet must be positioned as shown below. Outlet
must be flush with wall.
Before your new unit is connected to a power supply, check the incoming voltage with a volt meter. If anything
less than 100% of the rated voltage for operation is noted, correct immediately.
The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a standard
3-prong (grounding) wall outlet to minimize the possibility of electric shock hazard from this appliance. A 115V
AC, 60 Hz, 15 amp circuit breaker and electrical supply are required.
Each unit requires a dedicated circuit. Have the wall outlet and circuit checked by a qualified electrician to
make sure the outlet is properly grounded.
If the outlet is a standard 2-prong outlet, it is your personal responsibility and obligation to have it replaced with
the properly grounded 3 prong wall outlet.
Do not use an extension cord or two prong adaptor. Electrical ground is required on this appliance.
The unit should always be plugged into its own individual electrical circuit, which has a voltage rating that
matches the rating plate. This provides the best performance and also prevents overloading house wiring
circuits which could cause a fire hazard from overheated wires. Never unplug your refrigerator by pulling on
the power cord. Always grip plug firmly and pull straight out from the outlet.
Repair or replace immediately all power cords that have become frayed or otherwise damaged. Do not use
a cord that shows cracks or abrasion damage along its length or at either end. When moving the refrigerator
away from the wall, be careful not to roll over or damage the power cord.

HOME ALARM SYSTEM - DUAL ZONE WINE CABINET ONLY
Dual Zone wine units are provided with three wires located behind the kick-plate that may be connected
to a home alarm system. These connections are for low voltage, low current circuits similar to those used
as signals for alarms on doors and windows. Refer to the specifications of your alarm system to determine
the type of circuit used.
The color codes for the different circuits are as follows:
• Normally closed contacts: White with black and violet
• Normally open contacts: White with blue and black
• Common: White with black
CAUTION: ANY UNUSED TERMINALS SHOULD BE FULLY INSULATED AND ALL WIRES
SHOULD BE SECURED AWAY FROM MOVING PARTS AND SHARP EDGES.

refrigerator is not level adjust the stainless
steel leg levelers. The leg levelers can be
adjusted by turning CCW to reach the desired
leveling height as shown in the illustration
below.
STEP 3 - Free plug and cord from back of unit.
STEP 4 - The unit should be placed close enough to
the electrical supply so that extension cords
are never used. Plug unit directly into the
wall outlet.
STEP 5 - Once installed in final location, re verify level
and make final adjustments to the front legs.
STEP 6 - Insert the toe kick on the clips (A) Version or
