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
approximate temperature of 35°F and freezers an approximate
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.

followed, including the following:
TOOLS REQUIRED
STEP 1 - Disconnect power to unit.
STEP 2 - Remove the front grill by backing out four corner thumb
screws. See image 1.
STEP 3 - Remove bolts anchoring compressor assembly to frame
rails and carefully slide out. (tube connections are flexible)
STEP 4 - Clean off accumulated dirt from the condenser coil and
the fan with a stiff bristle brush. See image 2.
STEP 5 - Lift cardboard cover above fan at plastic plugs and
carefully clean condenser coil and fan blades.
STEP 6 - After brushing condenser coil vacuum dirt from coil, and
interior floor. See image 3.
STEP 7 - Replace cardboard cover. Carefully slide compressor
assembly back into position and replace bolts.
STEP 8 - Reinstall front grill assembly onto unit.Tighten all screws.

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. After 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.
b. The Differential is the non adjustable preprogrammed temperature.
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 its Differential, or it may show an
average temperature.
The most accurate temperature on a cabinets operation is to verify the product temperature.
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.
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.
