SAFETY INFORMATION
How to Maintain Your
Refrigerator to Receive the Most
Efficient and Successful Operation
You have selected one of the finest commercial refrigeration units made. It is
manufactured under strict quality controls with only the best quality materials
available. Your TRUE cooler when properly maintained will give you many
years of trouble-free service.
WARNING!
Use this appliance for its intended purpose as described in this Owner Manual.
This cabinet contains fluorinated greenhouse gas covered by the Kyoto Protocol
(please refer to cabinet's inner label for type and volume,
GWP of 134a= 1,300. R404a= 3,800).
SAFETY PRECAUTIONS
When using electrical appliances, basic safety precautions should be followed, including the following:
• 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 touch the cold surfaces in the freezer
compartment when hands are damp or wet.
Skin may stick to these extremely cold surfaces.
• Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
NOTE: We strongly recommend that any
servicing be preformed by a qualified
technician.
• Unplug the refrigerator before cleaning and
making repairs.
• Setting temperature controls to the 0 position
does not remove power to the light circuit,
perimeter heaters, or evaporator fans.
• Keep fingers out of the “pinch point” areas;
clearances between the doors and between
the doors and cabinet are necessarily small; be
careful closing doors when children are in the
area.

SAFETY INFORMATION
DANGER!
RISK OF CHILD ENTRAPMENT
PROPER DISPOSAL OF THE REFRIGERATOR
Child entrapment and suffocation are not problems
of the past. Junked or abandoned refrigerators are
still dangerous… even if they will sit for “just a few
days.” If you are getting rid of your old refrigerator,
please follow the instructions below to help
prevent accidents.
Before You Throw Away Your Old Refrigerator or
Freezer:
• Take off the doors.
• Leave the shelves in place so that children may
not easily climb inside.
Refrigerant Disposal
Your old refrigerator may have a cooling system
that uses “Ozone Depleting ” chemicals. If you are
throwing away your old refrigerator, make sure the
refrigerant is removed for proper disposal by a
qualified service technician. If you intentionally
release any refrigerants you can be subject to
fines and imprisonment under provisions of the
environmental regulations.
USE OF EXTENSION CORDS
NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been connected to
an extension cord.

SAFETY INFORMATION
WARNING!
HOW TO CONNECT ELECTRICITY
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.
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.
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.
The refrigerator should always be plugged into
it’s own individual electrical circuit, which has a
voltage rating that matches the rating plate.
This provides the best performance and also
prevents overloading building 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 removing the refrigerator away from the wall,
be careful not to roll over or damage the power
cord.
USE OF ADAPTER PLUGS
NEVER USE AN ADAPTER PLUG! Because of potential safety hazards under certain conditions, we strongly recommend
against the use of an adapter plug.
(North America Use Only!)
NEMA plugs
TRUE uses these types of plugs.
If you do not have the right outlet
have a certified electrician install
the correct power source.

INSTALLATION / OPERATION INSTRUCTIONS
INSTALLATION / OPERATION INSTRUCTIONS
OWNERSHIP
To insure that your unit works properly from the first
day, it must be installed properly. We highly recommend
a trained refrigeration mechanic and electrician install
your TRUE equipment. The cost of a professional
installation is money well spent.
Before you start to install your TRUE unit, carefully
inspect it for freight damage. If damage is discovered,
immediately file a claim with the delivery freight carrier.
TRUE is not responsible for damage incurred during shipment.
REQUIRED TOOLS
• Adjustable Wrench
• Phillips Head Screwdriver
• Level
UNCRATING
The following procedure is recommended for uncrating
the unit:
A. Remove the outer packaging, (cardboard and
bubbles or styrofoam corners and clear plastic).
Inspect for concealed damage. Again, immediately file
a claim with the freight carrier if there is damage.
B. Move your unit as close to the final location as
possible before removing the wooden skid.
C. Remove door bracket on swinging glass door models
(see image 1-2). Sliding glass door models contain
shipping blocks (three for each door). Remove
the two styrofoam blocks taped to the top of the
door tracks (see image 3). The shipping blocks are
orange in color and by opening the door a little
the blocks can be removed (see images 4-6). Do
not throw the bracket or blocks away. For future
cabinet movement the bracket and blocks will need
to be installed so the glass door does not receive any
damage. (See image for bracket and shipping block
removal)
Note: Keys for coolers with door locks are located in warranty
packets.
