SAFETY INFORMATION
PROPER DISPOSAL OF THE REFRIGERATOR
DANGER!
RISK OF CHILD ENTRAPMENT
Child entrapment and suffocation are not problems
of the past. Junked or abandoned display cases
are still dangerous... even if they will sit for “just a
few days.” If you are getting rid of your old display
case, 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.

SAFETY INFORMATION
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 unit 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 freezer 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 freezer 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 EXTENSION CORDS / ADAPTER PLUGS
TRUE will not warranty any display case that has been connected to an extension cord. Because of potential
safety hazards under certain conditions, we strongly recommend against the use of an adapter plug. NEVER
USE AN EXTENSION CORD! NEVER USE AN ADAPTER PLUG!
NEMA plugs
TRUE uses these types of plugs.
If you do not have the right outlet
have a certifi ed electrician install
the correct power source.

uncrating the unit:
A. Remove the outer packaging, (cardboard
and bubbles or styrofoam corners and clear
plastic). Inspect for concealed damage.Again,

INSTALLATION / OPERATION INSTRUCTIONS
LEVELING
Step 3
A. Set unit in its final location. Be sure there is
adequate 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 (for slide door
models) and door operation will be effected by
leveling.
C. The cooler should be leveled front to back and
side to side with a level.
D. Ensure that the drain hose or hoses are
positioned 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
6 1/2 ft. (2 m) from plug-in connection or extension
cord is used to supply power to unit.
Step 2
A. Remove skid by using a phillips head
screwdriver.
B. Remove the four brackets from the base of the
cooler.
C. Carefully move the cooler off the back of the
skid. Tilt the cooler backwards just enough to
remove the skid from under the cooler.
D. Free plug and cord from the lower rear of the
cooler (do not plug in).
E. The merchandiser should be placed close
enough to the electrical supply so that
extension cords are never used.
TCM "Air-Curtain Merchandisers"
A. Do not place unit in the path of air conditioning
or overhead heating ducts.
B. This "air-curtain" merchandiser is to be located
in a maximum ambient condition of 75˚F / 85%
relative humidity.
WARNING
Failure to comply will disrupt cooler performance!

INSTALLATION / OPERATION INSTRUCTIONS
Step 5
A. The compressor is ready to operate. Plug in the
unit.
B. Check the temperature control setting in the
upper left of the cabinet backside. The setting
should be at #5 to maintain an approximate
35˚F (1.6˚C). Temperature control is located in
lower rear of cabinet on ballast box.
Allow cooler to function several hours,
completely cooling cabinet before changing the
control setting.
C. The coolers are designed to maintain
temperatures from 30˚F to 45˚F (-1˚C to
7˚C) degrees according to the control setting.
Excessive tampering with the control could lead
to service difficulties. Should it ever become
necessary to replace temperature control, be
sure it is ordered from your True dealer or
authorized service agent.
D. Verify that the cabinet lights are working. The
lights are turned on/off by a switch position
above the evaporator housing.
E. Good air flow in you True unit is critical. Be
careful to load product based on the load limit
stickers positioned on the inside left and right
walls of the merchandiser.
NOTE
If the unit is disconnected or shut off, wait five minutes before
starting again.
RECOMMENDATION
Before loading product we recommend you run your True
unit empty for two to three days. This allows you to be sure
electrical wiring and installation are correct and no shipping
damage has occurred. Remember, our factory warranty does not
cover product loss!
REPLACEMENT PARTS
TRUE maintains a record of the cabinet serial number for your
unit. If at any time during the life of your display case, a part
is needed, you may obtain this part by furnishing the model
number and serial number to the company from whom you
purchased the cabinet. Call Toll-Free: (800)-424-TRUE (Direct
to Parts Department). (800)-325-6152 (U.S.A. & Canada only)
or call: (636)-240-2400.
STARTUP
Serial Number
Step 4
A. Before your new unit is connected to a power
supply, check the incoming voltage with a
voltmeter. If anything less than 100% of the
rated voltage for operation is noted, correct
immediately.
B. All units are equipped with a 9 ft. (2.74m)
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 rear louvered grill, wiring
diagram is positioned on the inside cabinet wall.

INSTALLATION / OPERATION INSTRUCTIONS
SEALING CABINET TO FLOOR
Optional
A. It may be necessary to seal the deli case to the
floor for local sanitary codes or if the customer
so desires. TRUE recommends either of the
following methods.
B. Using a vinyl cover base trim as produced by
Armstrong, Johnson, or Kentile (available at floor
covering suppliers) or
C. Using mastics available at hardware stores.
D. When applying the cove base trim, thoroughly
clean both the cabinet and floor of dirt and
grease. Apply a recommended contact cement
to the cove base trim. After cove base trim has
dried, fill in cracks and joints with a caulking
material.
E. When applying a mastic, draw an outline of the
cabinet on the floor. Raise and block the front
side of the cabinet. Apply a bead of mastic to
the floor 1/2” inside the outline drawn. Lower
the cabinet. Raise and block the rear side of the
cabinet. Apply the bead of mastic, lower the
cabinet.
BIN DIVIDER INSTALLATION
STAINLESS STEEL
SHELF INSTALLATION
NOTE
Convenience merchandisers
are shipped with bin dividers
in place. If it is necessary to
adjust spacing the following
procedure is recommended.
Step 1
A. Dividers are spring loaded
- push divider towards front
of the cooler to release from
rear grommeted holes.
B. Lineup divider front pegs
with desired holes and punch
through interior tape lining
of both top and bottom holes
- bottom peg first (front holes
are taped over to improve
insulation values).
Remove divider from the
front holes and line up
regular and spring loaded
rear pegs with holes in line
with those desired in front.
Insert as far as possible and
maneuver front pegs in place.
