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 forjust 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 usesOzone 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 Display Case:  
Take off the doors.  
Leave the shelves in place so that children may  
not easily climb inside.

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.  
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.  
Have the circuit checked by a qualified electrician  
to make sure it is properly grounded.  
The display case should always be plugged into it’s  
own individual electrical circuit, which has a volt-  
age rating that matches the rating plate.  
The display case should always be use it’s own indi-  
vidual electrical circuit, which has a voltage 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.  
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 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.  
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 mini-  
mize the possibility of electric shock hazard from  
this appliance.  
When removing the display case away from the  
wall, be careful not to roll over or damage the  
power cord.  
Have the circuit checked by a qualified electrician  
to make sure it is properly grounded.

REPLACEMENT PARTS  
TRUE maintains a record of the cabinet serial number  
for your unit. If at any time during the life of your dis-  
play 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 cabi-  
net. Call Toll-Free: (800)-424-TRUE (Direct to Parts  
Department). (800)-325-6152 (U.S.A. & Canada only)  
or call: (636)-240-2400.  
A. The compressor is ready to operate. Plug in the  
display case.  
B. Check the temperature control setting in the  
lower right of the cabinet backside. The set-  
ting should be at No. 3 position to maintain an  
approximate temperature of 38°F (3.3°C). Set  
defrost time clock to the correct time of day.  
Allow unit to function several hours, completely  
cooling cabinet before changing the control set-  
ting.  
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 rec-  
ommended service agent.  
D. Good air flow in your True unit is critical. Be  
careful not to overstock product or block air  
vents.  
E. Verify that the cabinet lights are working.

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.

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 orgrainare 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

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.
