How to Maintain Your Freezer

/ Refrigerator to Receive the Most

Efficient and Successful Operation

You have selected one of the finest commercial refrigeration units 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 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 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 other
appliance.

NOTE
We strongly recommend that any servicing be performed by
a qualified individual.

• Unplug the refrigerator before cleaning and
making repairs.

• Setting temperature controls to the off 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 FREEZER /
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.

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.

USE OF EXTENSION CORDS

NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been
connected to an extension cord.

SAFETY INFORMATION

WARNING!

HOW TO CONNECT ELECTRICITY

Do not, under any circumstances, cut or remove the 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
grounding plug which mates with a standard grounding wall
outlet to minimize the possibility of electric shock hazard from
this appliance.

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 wall outlet.

The refrigerator 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 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.

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.

(North America Use Only!)

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.

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.

On most of the units the condenser is accessible in the rear of the unit. You must remove the cabinet grill to expose the
Condenser.

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

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

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.

SINCE 1945

TRUE warrants to the original purchaser of every new TRUE refrigerated unit, the cabinet and all parts thereof, to be free from defects in material or workmanship,
under normal and proper use and maintenance service as specified by TRUE and upon proper installation and start-up in accordance with the instruction packet supplied
with each TRUE unit. TRUE’s obligation under this warranty is limited to a period of one (1) year from the date of original installation or 15 months after shipment date
from TRUE, whichever occurs first.
Any part covered under this warranty that are determined by TRUE to have been defective within one (1) year of original installation or fifteen (15) months after
shipment date from manufacturer, whichever occurs first, is limited to the repair or replacement, including labor charges, of defective parts or assemblies. The labor
warranty shall include standard straight time labor charges only and reasonable travel time, as determined by TRUE.

In addition to the one (1) year warranty stated above, TRUE warrants its hermetically and semi-hermetically sealed compressor to be free from defects in both
material and workmanship under normal and proper use and maintenance service for a period of four (4) additional years from the date of original installation but not to
exceed five (5) years and three (3) months after shipment from the manufacturer.

Compressors determined by TRUE to have been defective within this extended time period will, at TRUE’s option, be either repaired or replaced with a compressor

or compressor parts of similar design and capacity.
The four (4) year extended compressor warranty applies only to hermetically and semi-hermetically sealed parts of the compressor and does not apply to any other
parts or components, including, but not limited to, cabinet, paint finish, temperature control, refrigerant, metering device, driers, motor starting equipment, fan assembly
