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 refrigera-
tor, 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.
APPLIANCE DISPOSAL
When recycling appliance please make sure that the refrigerants are
handled according to local and national codes, requirements and
regulations.
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 quali-
fied 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 war-
ranty any refrigerator that has been connected to an extension cord.
REPLACEMENT PARTS
• Component parts shall be replaced with like components.
• Servicing shall be done by authorized service personnel, to
minimize the risk of possible ignition due to incorrect parts or
improper service.
• Lamps must be replaced by identical lamps only.
• If the supply cord is damaged, it must be replaced by a special
cord or assembly available from the manufacturer or its service
agent.
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 from this appliance is equipped with a grounding
plug which minimizes the possibility of electric shock hazard.
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 respon-
sibility 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 over-
heated 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.
If supply power cord is damaged it should be replaced with original
equipment manufacture parts. To avoid hazard this should be done
by a qualified service technician.
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 including any adapters
used must have the adequate power available and must be properly
grounded. Only adapters listed with UL should be used.
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.
NOTE: International plug configurations vary by voltage and country.

OPERATION
STARTUP
A. The compressor is ready to operate. Plug in the cooler.
B. Temperature controls are factory-set to give refrigerators an
approxiate temperature of 35°F and freezers an approxiate
temperature of -10°F. Allow unit to function several hours,
completely cooling cabinet before changing the control setting.
Temperature Control Location and Settings.
• Electronic temperature control is located on rear of unit or
behind access grill.
• LAE temperature control is located on the front of cabinet
countertop or in/behind louvered grill.
• Mechanical temperature control is located inside of unit.
See website for adjustments, sequence of operation, and more
information.
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.
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.
NOTE: If the unit is disconnected or shut off, wait five minutes
before starting again.
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 ship-
ping damage has occurred. Remember, our factory warranty does not
cover product loss!

MECHANICAL TEMPERATURE CONTROLS
COIL SENSING
An evaporator coil sensing temperature control ensures that the evaporator coil will remain clear
of frost and ice by not allowing the compressor to restart until the coil temperature is above the
freezing temperature. This is considered an off cycle defrost.
MECHANICAL TEMPERATURE CONTROL GENERAL SEQUENCE OF OPERATION
MECHANICAL CONTROL REFRIGERATOR GENERAL SEQUENCE OF OPERATION
1. Cabinet is plugged in.
a. Interior lights will illuminate on Glass Door Models only. If lights do not come on verify the light switch is in the “ON”
position. Solid door cabinets may or may not have lights that may be controlled by the door switch.
2. The compressor and evaporator fans will start if the temperature control is calling for cooling. (If the compressor does not
start, verify that the temperature control is not in the “OFF” or “0” position.)
3. The temperature control may cycle the compressor and evaporator fan(s) on and off together.
a. The temperature control is sensing the evaporator coil temperature.
b. The temperature control should be set on the #4 or #5.
c. The warmest setting is #1, the coldest is #9, and #0 is the off position.
d. The thermometer is designed to read and display a cabinet temperature not a product temperature.
The thermometer may reflect the refrigeration cycle swings of up and down temperatures.
The most accurate temperature on a cabinet's operation is to verify the product temperature.
4. There is not a defrost timer as the temperature control will initiate the off-cycle defrost during each refrigeration cycle.
a. At this time, the compressor will and the evaporator fan(s) may turn off. Defrost heaters are not installed on refrigerators
and therefore will not be energized.
b. After the evaporator coil temperature has been reached, as determined by the temperature control, the compressor will
restart.
5. There may be a timer located on the condensing unit base. This timer is not used for a defrost event. The timer will change
the rotation of the reversing condenser fan motor.

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 refrigera-
tion service company.
On most of the reach-in 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.

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.
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.
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 the recommended strength (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
