RISK OF CHILD
ENTRAPMENT
PROPER DISPOSAL OF THE CABINET
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.

OWNERSHIP
To ensure that your unit works properly from the first day, it must
be installed properly. We highly recommend a trained refrigeration
mechanic and electrician install your TRUE equipment. The cost of a
professional installation is money well spent.
Before you start to install your TRUE unit, carefully inspect it for
freight damage. If damage is discovered, immediately file a claim with
the delivery freight carrier.
TRUE is not responsible for damage incurred during shipment.
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
to the top of the door tracks (see image 3). The shipping blocks
are orange in color and by opening the door a little the blocks
can be removed (see images 4-6). Do not throw the bracket
or blocks away. For future cabinet movement the bracket and
blocks will need to be installed so the glass door does not
receive any damage. (See image for bracket and shipping block
removal)

SEALING CABINET TO FLOOR
STEP 1 - Position Cabinet - Allow one inch between the wall and
rear of the refrigerator to assure proper ventilation. For freezers 3
inches between the wall and rear of the cabinet will assure proper
ventilation.
STEP 2 - Level Cabinet - Cabinet should be level, side to side and
front to back. Place a carpenter’s level in the interior floor in four
places:
A. Position level in the inside floor of the unit near the doors.
(Level should be parallel to cabinet front). Level cabinet.
B. Position level at the inside rear of cabinet. (Again level should
be placed parallel to cabinet back).
C. Perform similar procedures to steps A & B by placing the level
on inside floor (left and right sides - parallel to the depth of the
cooler). Level cabinet.
STEP 3 - Draw an outline on the base on the floor.
STEP 4 - Raise and block the front side of the cabinet.
STEP 5 - Apply a bead of “NSF Approved Sealant”, (see list below),
to floor on half inch inside the outline drawn.The bead must be heavy
enough to seal the entire cabinet surface when it is down on the
sealant.
STEP 6 - Raise and block the rear of the cabinet
STEP 7 - Apply sealant on floor as outlined in Step 5 on other
three sides.
STEP 8 - Examine to see that cabinet is sealed to floor around
entire perimeter.
NOTE: Asphalt floors are very susceptible to chemical attack. A
layer of tape on the floor prior to applying the sealant will protect
the floor.

STARTUP
A. The compressor is ready to operate. Plug in the cooler.
B. Temperature controls are factory-set to give Ice Merchandisers
an approxiate temperature of 20-25°F (-6.7 to -3.9°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.
• 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
shipping damage has occurred. Remember, our factory warranty does
not cover product loss!
LIGHT SWITCH LOCATION:
GDIM models will have the light switch located on the right side on
the ceiling inside the unit. Most instances the switch is located next
to the temperature control.

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.

per day.
DEFROST TIMER
DEFROST TIME CLOCK OPERATION FOR UNITS
WITH MECHANICAL CONTROL
RECOMMENDED DEFROST SETTINGS:
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 evapo-
rator 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.
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).
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.

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 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
