WARNING!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
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 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.

SEALING CABINET TO FLOOR
STEP 1 - Position Cabinet - Allow one inch between the wall and
rear of the refrigerated Bar Equipment to assure proper ventilation.
For Glass & Plate Chillers/Frosters 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.
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 ex tension cords are never used.
