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!

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.

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.

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.

Condensers accumulate dirt and require cleaning every 30 days. Dirty condensers
result in compressor failure, product loss, and lost sales... which are not covered
by warranty.
If you keep the Condenser clean you will minimize your service expense and lower your electrical costs.
The Condenser requires scheduled cleaning every thirty days or as needed.
Air is pulled through the Condenser continuously, along with dust, lint, grease, etc.
A dirty Condenser can result in NON-WARRANTEED part & Compressor Failures, Product Loss, and Lost
Sales.
Proper cleaning involves removing dust from the Condenser. By using a soft brush, or vacuuming the
Condenser with a shop vac, or using CO2, nitrogen, or pressurized air.
If you cannot remove the dirt adequately, please call your refrigeration service company.
The Condenser looks like a group of vertical fins. You need to be able to see through the condenser for
the unit to function at maximum capacity. Do not place filter material in front of condensing coil. This
material blocks air-flow to the coil similar to having a dirty coil.
THE CLEANING OF THE CONDENSER IS NOT
COVERED BY THE WARRANTY!
HOW TO CLEAN THE CONDENSER:
1. Disconnect the electrical power to the unit.
2. Remove the louvered grill.
3. Vacuum or brush the dirt, lint, or debris from the finned condenser coil.
4. If you have a significant dirt build up you can blow out the condenser with compressed air.
(CAUTION MUST BE USED to avoid eye injury. Eye protection is recommended.)
5. When finished be sure to replace the louvered grill. The grill protects the condenser.
6. Reconnect the electrical power to the unit.
If you have any questions, please call True Manufacturing at 636-240-2400 or 800-325-6152 and
ask for the Service Department. Service Department Availability Monday-Friday 7:30 a.m. to

MAINTENANCE, CARE & CLEANING
MAINTENANCE, CARE & CLEANING
CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless
steel surfaces.
Stainless Steel Opponents
There are three basic things which can break down your stainless steel’s passivity layer and allow
corrosion to rear its ugly head.
1) Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be
abrasive to stainless steel’s surface.
2) Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on
what part of the country you live in. Hard water can leave spots. Hard water that is heated can
leave deposits if left to sit too long. These deposits can cause the passive layer to break down and
rust your stainless steel. All deposits left from food prep or service should be removed as soon as
possible.
3) Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst
type of chlorides to use.
8 steps that can help prevent rust on stainless steel:
1. Using the correct cleaning tools
Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s passive layer
will not be harmed by soft cloths and plastic scouring pads. Step 2 tells you how to find the
polishing marks.
2. Cleaning along the polish lines
Polishing lines or “grain” are visible on some stainless steels. Always scrub parallel to visible lines on
some stainless steels. Use a plastic scouring pad or soft cloth when you cannot see the grain.
3. Use alkaline, alkaline chlorinated or non-chloride containing cleaners
While many traditional cleaners are loaded with chlorides, the industry is providing an ever
increasing choice of non-chloride cleaners. If you are not sure of your cleaner’s chloride content
contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask if
they have an alternative. Avoid cleaners containing quaternary salts as they can attack stainless steel,
causing pitting and rusting.
4. Water Treatment
To reduce deposits, soften the hard water when possible. Installation of certain filters can remove
corrosive and distasteful elements. Salts in a properly maintained water softener can be to your
advantage. Contact a treatment specialist if you are not sure of the proper water treatment.
5. Maintaining the cleanliness of your food equipment
Use cleaners at recommended strength (alkaline, alkaline chlorinated or non-chloride). Avoid
build-up of hard stains by cleaning frequently. When boiling water with your stainless steel
equipment, the single most likely cause of damage is chlorides in the water. Heating any cleaners
containing chlorides will have the same damaging effects.
6. Rinse
When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe
standing cleaning agents and water as soon as possible. Allow the stainless steel equipment to air
dry. Oxygen helps maintain the passivity film on stainless steel.
7. Hydrochloric acid (muriatic acid) should never be used on stainless steel
8. Regularly restore/passivate stainless steel

1. This system contains R404A or R134A refrigerant and polyol ester lubricant. The polyol ester lubricant has rapid moisture absorbing qualities. If long
exposure to the ambient conditions occur, the lubricant must be removed and replaced with new. For oil amounts and specifications please call True tech-
nical service department (800-325-6152). Failure to comply with recommended lubricant specification will void the compressor warranty.
