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.
BEFOREYOU THROW AWAYYOUR 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
NEVER USE AN EXTENSION CORD! TRUE will not warranty 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.
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.
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.

ELECTRIC INSTALLATION & SAFETY INFORMATION
•If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
•Lamps must be replaced by identical lamps only.
•Appliance tested according to the climate classes 5 and 7 temperature and relative humidity.
ELECTRICAL INSTRUCTIONS
A.Before your new unit is connected to a power supply, check the incoming voltage with a voltmeter. If anything less than 100% of the rated voltage for operation is noted, correct immediately.
B.All units are equipped with a service cord, and must be powered at proper operating voltage at all times. Refer to cabinet data plate for this voltage.
TRUE RECOMMENDS THAT A SOLE USE CIRCUIT BE DEDICATED FOR THE UNIT.
WARNING: Compressor warranties are void if compressor burns out due to low voltage.
WARNING: Power supply cord ground should not be removed!

D.Cut straps if applicable. See image 6.
E.Carefully lift cabinet off of skid.
LEVELING
A.Set unit in its final location. Be sure there is adequate ventilation in your room. Under extreme heat conditions, (100°F+, 38°C+), you may want to install an exhaust fan.
WARNING: WARRANTY IS VOID IF VENTILATION IS INSUFFICIENT.
B.Proper leveling of your TRUE cooler is critical to operating success (for non-mobile models). Effective condensate removal and door operation will be effected by leveling.
C.The cooler should be leveled front to back and side to side with a level.
D.Ensure that the drain hose or hoses are positioned in the pan.
E.Free plug and cord from inside the lower rear of the cooler (do not plug in).
F.The unit should be placed close enough to the electrical supply so that extension cords are never used.
NOTE: If the cabinet has a center leveling screw, castor, or leg, make sure it is adjusted properly so it makes full contact with the floor after the cabinet has been leveled.

•Electronic control with display:
-In countertop
-In top louvered panel
-In or behind bottom louvered grill
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: The light switch is located behind the interior light inside the cabinet. HC cabinet lights are turned on/off through the LAE temperature control. See page 14.
