SAFETY PRECAUTIONS
When using electrical appliances, basic safety precautions should be followed, including the following:
This freezer must be properly installed and
located in accordance with the Installation
Instructions before it is used.
NOTE: We strongly recommend that any
servicing be preformed by a qualified
individual.
Do not allow children to climb, stand or hang
on the shelves in the freezer. They could
damage the freezer and seriously injure
themselves.
Unplug the freezer 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.
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

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.
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.
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.
USE OF EXTENSION CORDS
NEVER USE AN EXTENSION CORD! TRUE will not warranty any freezer 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.
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.
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.
When removing the freezer away from the wall, be
careful not to roll over or damage the power cord.
The freezer 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
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.
The incoming power source to the cabinet

cooling cabinet before changing the control setting.
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!
C. 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 recommended
service agent.
REPLACEMENT PARTS
TRUE maintains a record of the cabinet serial
number for your cooler. If at any time during the
life of your cooler, 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 cooler. Call Toll-Free: (800)-
424-TRUE (Direct to Parts Department). (800)-
325-6152 (U.S.A. & Canada only) or call: (636)-
240-2400.
D. Good air flow in your True unit is critical. Be
careful to load product so that it neither presses
against the back wall, nor comes within four inches
of the evaporator housing. Refrigerated air off the
coil must circulate down the back wall.
LIGHT SWITCH LOCATION:
GDIM models will have the light switch located on the
right side on the ceiling inside the unit. Most instances
the switch is located next to the temperature control.

RECOMMENDED DEFROST
STEP 1
SETTINGS:
Your True freezer contains a defrost system
that is temperature terminated, however the
time clock has been designed with a time
termination back-up so that the defrost
period will not exceed thirty minutes.
While True requires a minimum 3 defrost
periods not to exceed 30 minutes the
procedure on this page should be followed
to customize your specific needs.
The white tabs located on the outmost area
of the time clock have been factory set for

Each tab represents 15 minutes of defrost
time. Notice that at each defrost time two
white tabs are set for 15 minutes each for a
total of 30 minutes of defrost.
True Manufacturing has factory set your
defrost time clock to a recommended time
and duration defrost scenario. All
refrigeration equipment operating below
30°F will accumulate frost on the
evaporator coil and will require routine
defrost. Your True equipment has been
designed for three defrost periods (6:00

MAINTENANCE, CARE & CLEANING
IF THE COMPRESSOR WILL
NOT RUN
1. If there is no voltage at the
compressor terminals, follow the wiring
diagram and check back from
compressor to the power supply to find
where the circuit is interrupted.
Make sure capacitors are discharged
before checking. Check for continuity
between each capacitor terminal and
the case. Continuity indicates a short,
and the capacitor should be replaced.
5. If the compressor has an external
protector, check for continuity through
the protector or protectors.
All external inherent protectors on
compressors can be replaced in the

compressor is operating. Be sure the
pressures are within the limitations of
the compressor. If pressures are
excessive it may be necessary to clean
the condenser, purge air from the
system, replace crankcase pressure

If a capacitor tester is not available, an
ohmmeter may be used to check run
and start capacitors for shorts or open
circuits. Use an ohmmeter set to its
highest resistance scale, and connect
prods to capacitor terminals.
If voltage at the compressor terminals
is below 90% of the nameplate voltage,
it is possible the motor may not
develop sufficient torque to start.
Check to determine if wire sizes are
adequate, electrical connections are
loose, the circuit is overloaded, or if the
power supply is inadequate.

Stainless Steel Equipment Care and 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

Recommended cleaners for certain situations / environments of
stainless steel
A) Soap, ammonia and detergent medallion applied with a cloth or sponge can be used for routine
cleaning.
B) Arcal 20, Lac-O-Nu Ecoshine applied provides barrier film for fingerprints and smears.
C) Cameo,Talc, Zud First Impression is applied by rubbing in the direction of the polished lines for
stubborn stains and discoloring.
D) Easy-off and De-Grease It oven aid are excellent for removals on all finishes for grease-fatty acids,
blood and burnt-on foods.
E) Any good commercial detergent can be applied with a sponge or cloth to remove grease and oil.
F) Benefit, Super Sheen, Sheila Shine are good for restoration / passivation.
NOTE:
The use of stainless steel cleaners or other such solvents is not
recommended on plastic parts. Warm soap and water will suffice.
LIGHT BULB REPLACEMENT
WARNING:
Disconnect power to cabinet before
replacing light bulbs.
IDL (INTEGRATED DOOR LIGHTING):
Squeeze the plastic lampshield together and pull
away from the door (See Image 1).
Push the bulb down while pulling the spring
