SAFETY INFORMATION

How to Maintain Your Unit

to Receive the Most Efficient and

Successful Operation

You have selected one of the finest display cases 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 display case 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 display case. They could
damage the refrigerator and seriously injure
themselves.

• Do not touch the cold surfaces in the refrigerat­ed 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 individual.

• Unplug the refrigerator before cleaning and
making repairs (switch power off at breaker for
hard wired models).

• 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 DISPLAY CASE

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 Display Case:

• Take off the doors.

• Leave the shelves in place so that children may not
easily climb inside.

CFC 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

TRUE will not warranty any display case that has been connected to an extension cord.

SAFETY INFORMATION

WARNING!

HOW TO CONNECT ELECTRICITY

Hard wiring is required on specific Display Cases.
Models standard with power cords: 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.

Before your new display case 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.

Have the circuit checked by a qualified electrician
to make sure it is properly grounded.

The display case should always be use 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.

For models with standard power cord.

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 circuit checked by a qualified electrician
to make sure it 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 display case 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 display case 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 display case away from the
wall, be careful not to roll over or damage the
power cord.

USE OF ADAPTER PLUGS

NEVER USE AN ADAPTER PLUG!

location as possible before removing the
wooden skid.

LOCATING

TOOLS REQUIRED:

• Phillips screw driver

• 3/8” (9.5 mm) socket or 3/8” (9.5 mm) wrench

Step 2
A. Use a Phillips screw diver and remove four

screws from the L-bracket connected the unit
to the wood skid (image 1). Then use a 3/8”
(9.5 mm) socket or wrench and remove the
L-bracket from the unit (image 2).

To avoid damage to glass DO NOT lay cabinet

on its side or back when removing skid,

installing leg levelers, cleaning, etc.

B. Lift up from the base and walk unit off the skid

and set in final location.

C. Unblock doors, free plastic wedges, blue foam

and tape. Remove fiberglass tape securing glass.

Remove components: (shelves, brackets, etc.)

from inside cabinet.

Warning
For proper performance of refrigerated cabinet an
ambient temperature no greater than 75°F (24°C) with a
relative humidity of 55% is required.

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 unit is critical to

operating success (for non-mobile models).
Effective condensate removal and door operation
will be effected by leveling.

Warning
Display case must be leveled accurately to ensure front
glass door seals properly.

C. The unit should be leveled front to back and

side to side with a level. Place the level in the
interior floor of the unit and check all four sides.

D. If the cabinet is not level adjust leg levelers by

first relieving weight to leveler and adjusting
by either hand or wrench. Repeat with all leg
levelers until cabinet is level in all directions.

E. Ensure that the drain hose or hoses are

positioned in the pan.

F. Models with power cord: Free plug and cord

from inside the lower rear of the cooler (do not
plug in).

G. Models with power cord: 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
9 ft. (3 m) from plug-in connection or an extension cord
is used to connect unit to a power supply.
