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 refrigera-
tor 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.
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.
NOTE: We strongly recommend that any
servicing be preformed by a qualified
individual.
Unplug the refrigerator before cleaning and
making repairs.
Setting temperature controls to the 0 position
does not remove power.
WARNING!
Use this appliance for its intended purpose as described in
this Owner Manual.

PROPER DISPOSAL OF THE REFRIGERATOR
DANGER!
RISK OF CHILD ENTRAPMENT
USE OF EXTENSION CORDS
NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been
connected to an extension cord.
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 pre-
vent 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.

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 mini-
mize the possibility of electric shock hazard from
this appliance.
Have the wall outlet and circuit checked by a quali-
fied 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 volt-
age rating that matches the rating plate.
This provides the best performance and also pre-
vents 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.
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.
WARNING!
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.

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 discov-
ered, immediately file a claim with the delivery
freight carrier.

ly 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 swing glass door
models (see image 1-2).

INSTALLATION OF LEGS AND CASTORS
Important Safeguard for installation of leg/castor (Images 1-5 demonstrate procedure)
Step 3
Securing Castors and Legs
To obtain maximum strength and stability of the
unit, it is important that you make sure each castor
is secure. Legs are hand-tightened securely against
the lower rail assembly. The bearing race on the
castor of the top edge of the leg must make firm
contact with the rail.
Unit leveling
Four leveling shims have been provided for level-
ing castored units positioned on uneven floors.
Shims must be positioned between rail end and
bearing race. True requires a four shim limit to
each individual castor.
A. Turn the bearing race counter-clockwise until
the cabinet is level. Level front to back and side to
side. (diagonally)
B. Install the desired number of shims, making sure
the slot of the shim is in contact with the threaded
stem of the castor.
C. If more than one shim is used, turn the slot at a
90° angle so they are not in line.
D. Turn the bearing race clockwise to tighten and
secure the castor by tightening the anchoring bolt
with a 3/4 inch open-end wrench or the tool
provided.
CAUTION
To avoid damage to lower rail assembly,
slowly raise unit to upright position.

TSSU Hood Installation Instruction
A. Remove rear grill and thread electric cord This is
True’s recommended procedure for installing the
fasteners required to connect the sandwich salad
hood cover to the hood.
See callout #1 on the illustration.
Assembly
1. Locate the hood cover, (packaged within the
cardboard container on top of the salad sandwich
unit), and position under the hood.
2. Remove the slotted thumb screw from hood by
backing out the factory installed, slotted thumb
screw. See diagram of slotted screw and callout #2.
3. Place hood cover into final position, (beneath
hood), align hood hinge pin with anchor hole on
hood cover and re-attach fastener by replacing
thumb screw into hinge pin.

Step 7
A. 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 volt-
age for operation is noted, correct immediately.
B. All units are equipped with a 7 ft. (2.1m) service
cord, and must be powered at proper operating
voltage at all times. Refer to cabinet data plate for
this voltage.
True requires that a sole use circuit be dedicated
for the unit. Failure to do so voids warranty.
WARNING
Compressor warranties are void if compressor
burns out due to low voltage.
WARNING
Power supply cord ground should not be
removed!
NOTE
To reference wiring diagram - Remove front lou-
vered grill, wiring diagram is positioned on the
inside cabinet wall.
ELECTRICAL INSTRUCTIONS
Step 6
A. Set unit in its final location. Be sure there is ade-
quate ventilation in your room. Under extreme heat
conditions, (100°F+, 38°C+), you may want to install
an exhaust fan.
Warning
Warranty is void if ventilation is insufficient.
B. Proper leveling of your True cooler is critical to
operating success (for non-mobile models). Effective
condensate removal and door operation will be
effected by leveling.
C. The cooler should be leveled from inside the
cabinet. Place a level on the inside floor of the unit
front to back and side to side.
D. Ensure that the drain hose or hoses are posi-
tioned in the pan.
E. Free plug and cord from inside the lower rear of
the cooler (do not plug in).
F. The unit should be placed close enough to the
electrical supply so that extension cords are never
used.
Warning
Compressor warranties are void if the unit is more
than 7 ft. (2.1m) from plug-in connection. TRUE
will not warranty any units that are connected to
an extension cord.
