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.
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 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
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 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 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.
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.
NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been connected to an extension cord.
USE OF ADAPTER PLUGS
REPLACEMENT PARTS
NEVER USE AN ADAPTER PLUG! Because of potential safety
hazards under certain conditions, we strongly recommend against the
use of an adapter plug.
•
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.
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!

UNCRATING
TOOLS REQUIRED
• Adjustable Wrench
•
Phillips Screwdriver
•
Level
The following procedure is recommended for uncrating the unit:
A. Remove the outer packaging, (cardboard and bubbles or
Styrofoam corners and clear plastic). Inspect for concealed
damage. Again, immediately file a claim with the freight carrier
if there is damage.
B. Move your unit as close to the final location as possible before
removing the wooden skid.
C. Remove door bracket on swinging glass door models (see
image 1-2). Sliding glass door models contain shipping blocks
(three for each door). Remove the two Styrofoam blocks taped

operation
STARTUP
A. The compressor is ready to operate. Plug in the cooler.
B. Temperature controls are factory-set to give refrigerators
an approximate temperature of 35°F (1.6°C) and freezers
an approximate temperature of -10°F (-23.3°C). 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.
• L AE 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
shipping damage has occurred. Remember, our factory warranty does
not cover product loss!
LIGHT SWITCH LOCATION:
Light switch location depends upon the T-Series model. Most T-Series
models will have the light switch located inside the unit on the right
side of the ceiling. Most instances the switch is located next to the
temperature control. Some models have the switch located on the
right side of the evaporator housing along the interior ceiling.
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.
AIR SENSING
An air sensing temperature control used in a freezer application will require a defrost cycle with
heaters to ensure that the evaporator coil is kept clear of frost and ice.

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.
MECHANICAL CONTROL FREEZER 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 only 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 or the cabinet is not in a defrost event.)
a.The evaporator fan(s) will remain off until a specific temperature of the evaporator coil is reached.
3.
The temperature control may cycle the compressor and evaporator fan(s) on and off together.
a.The temperature control is sensing the air 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. The defrost timer will initiate defrost during specific times of day.
a. At this time, the compressor and evaporator fan(s) will turn off and the evaporator coil heater and drain tube heater will
be energized. Some cabinets may also change the rotation of the reversing condenser fan motor.
b. After the predetermined evaporator coil temperature has been reached or duration for defrost has expired, the
compressor will restart and the evaporator fan(s) will remain off until a specific temperature of the evaporator coil is
reached.

STEP 1 - Unplug cooler.
STEP 2 - Remove the screws that secure the temperature control to the inset box.
STEP 3 - To make these adjustments it may be necessary to remove the temperature control from the housing.
NOTE: You may have to remove the wires attached to the control. Take note as to which wire is on which spade terminal.
STEP 4 - Pull out gently from cabinet.
NOTE: Mechanical temperature controllers are affected when functioning at high altitude.
The cut-in and cut-out temperatures will be colder than when the controller functions closer to sea level.
STEP 5 - For high elevation installations, it may be necessary to “warm-up” the set points. To make the adjustment, insert the
appropriate tool in each adjustment screw and turn 1/4 of a revolution clockwise (to the right). This procedure will adjust both
the cut-in and cut-out about 2˚F warmer.
STEP 6 - Make sure to reconnect the wires to the proper spade terminal when reinstalling.

DEFROST TIMER
Defrost Time Clock Operation for units
WITH MECHANICAL CONTROL
NOTICE: If timer is not set for a minimum of 3 defrost per day
for 30 minutes each, the coil may develop excessive frost. This may
lead to system failure and product loss, which is not covered under
warranty.
RECOMMENDED DEFROST SETTINGS:
The following procedure may be followed to customize your needs.
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 a.m., 2:00 p.m. and
10:00 p.m.). If you decide to deviate from these defrost time settings
please follow the procedures for adjustment below.
High usage, high temperature, and high humidity may require 4
defrost settings per day.
TOOLS REQUIRED
• Phillips Head Screwdriver
• 1/4" Nut Driver or Socket
Setting the timer:
UNPLUG UNIT FROM POWER SUPPLY! DO NOT SET THE TIME
BY ROTATING THE “OUTER” DIAL.
Turn the minute hand clockwise until the time of day on the outer
dial is aligned with the triangle marker on the inner dial (two o’clock
position).
WARNING: Always follow the manufacturer’s recommended
settings when programming the amount and duration of the defrost
cycles.
STEP 1: The white tabs located on the outmost area of the time
clock have been factory set for (6:00 a.m., 2:00 p.m., and 10:00
p.m.). 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.
STEP 2: In order to program the time to begin the defrost cycle,
flip the white tabs out to set the defrost time. To eliminate a defrost
time flip the white tabs back toward the center of the Defrost
Timer.
STEP 3: TRUE recommends a 30 minute defrost cycle three times
per day.
Adjusting The Defrost Timer:
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.

ELECTRONIC Temperature Controls
LAE ELECTRONIC TEMPERATURE CONTROL GENERAL SEQUENCE OF OPERATION
t1 = supply air / return air* (thermostat)
* STA, STG, STM, STR Models.
t2 = coil / copper line (defrost)
t3 = return air / supply air* (display)
t3 probe is not installed and / or activated in all applications
with t3 is not installed and / or activated, the display probe is t1.
LAE ELECTRONIC CONTROL GENERAL SEQUENCE OF OPERATION
1. Cabinet is plugged in.
a.Display will illuminate.
b.Interior light will illuminate on Glass Door Models only. Solid door cabinet lights are controlled by the door switch.
2. A
fter the LAE control preprogrammed time delay of up to 6 minutes, the compressor and evaporator fan(s) will
start if the control is calling for cooling.
a.Control or condenser fans may be already pre-programmed from the factory so at the start of every compressor cycle or
during a defrost cycle, the condenser fan(s) will reverse for 30 seconds to blow dirt off the condensing coil.
3. The LAE control will cycle the compressor but may also cycle evaporator fan(s) on and off determined by the
Set-Point and Differential temperatures.
a.The Set-Point is the adjustable preprogrammed temperature which shuts off the compressor and evaporator fan(s).
This is not the programmed cabinet temperature.
b. The Differential is the non adjustable preprogrammed temperature that is added to the Set-Point temperature that
will restart the compressor and evaporator fan(s).
c. The LAE control is designed to read and display a cabinet temperature not a product temperature.
This cabinet temperature may reflect the refrigeration cycle of the Set-Point and it’s Differential.
The most accurate temperature on a cabinets operation is to verify the product temperature.
Example: If the Set-Point is -9°F/-23°C and the Differential is 10°F/5°C
(Set-Point) -9°F + 10 (Differential) = 1°F
Or
(Set-Point) -23°C + 5 (Differential) = -18°C
The compressor and evaporator fan(s) will cycle off -9°F/-23°C and back on at 1°F/-18°C
4. The LAE control may be preprogrammed to initiate defrost by interval or at specific times of day.
a. At this time the “dEF” will appear on the display and compressor will turn off until a preprogrammed temperature
or duration is reached. During this time for freezers only, evaporator fan(s) will also turn off and the coil heater and
drain tube heaters will also be energized. Some cabinets may also change the rotation of the reversing condenser
fan motor.
17
b. After the preprogrammed temperature or duration for defrost has been reached there may be a short delay
for both the compressor and evaporator fans to restart. At this time “dEF” may still appear on the display for a
short time.

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 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.

STAINLESS STEEL EQUIPMENT CARE
AND CLEANING
8 steps that can help prevent rust on
stainless steel:
CAUTION: Do not use any steel wool, abrasive or chlorine based
products to clean stainless steel surfaces.
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.
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.
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
