SAFETY PRECAUTIONS
When using electrical appliances, basic safety precautions should be followed, including the following:
• This refrigerator must be properly installed
and located in accordance with the Installation
Instructions before it is used.
NOTE: We strongly recommend that any servicing be
performed by a qualified individual.
• Unplug the refrigerator before cleaning and
making repairs.
• Do not allow children to climb, stand or hang
on the shelves in the refrigerator. They could
damage the refrigerator and seriously injure
themselves.
• Setting temperature controls to the 0 position
does not remove power to the light circuit or
evaporator fans.
• 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

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 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.
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 display case 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.
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.
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.
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.
NEMA plugs
TRUE uses these types of plugs.
If you do not have the right outlet
have a certified electrician install
the correct power source.

possible before removing the wooden skid.
The following procedure is recommended for
uncrating the unit:
A. Remove the outer packaging by pulling tri-wall
nails from skid. Remove (4) cardboard corner
pads and dust cover.
B. Inspect for concealed damage. Again,
immediately file a claim with the freight carrier
if there is damage.
LOCATING

MAINTENANCE, CARE & CLEANING
IMPORTANT WARRANTY INFORMATION
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 gill 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

MAINTENANCE, CARE & CLEANING
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

MAINTENANCE, CARE & CLEANING
STAINLESS STEEL EQUIPMENT CARE AND CLEANING
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.
Light Bulb Replacement:
• Hold firmly on the end of the light bulb and pull toward the center of the cabinet. The lampholders are spring
activated so the bulb can easily be replaced. (See Image 1).
• When installing a new bulb make sure the prongs at the end of the bulb seat appropriately into the lampholder.
