Safety Precautions
Thermo King recommends that all services be performed by a
Thermo King dealer. However, there are several general safety
practices which you should be aware of:
WARNING: Always wear goggles or safety glasses
when working with or around the refrigeration
system or battery. Refrigerant or battery acid can
cause permanent damage if it comes in contact with
your eyes.
IMPORTANT: Thermo King will not be held liable
for claims for damage resulting from the following:
• Misuse, improper installation, abnormal service,
storage of hazardous chemicals, use of corrosive
substances, transit damage, recharging of
cooling system, accident, fire, improper repair,
tampering or abuse.
• Incorrect voltages or faults with regard to power
supply which falls outside of the Cold Cube
operating parameters.
CAUTION: Danger of fatal injury from electric
shocks! When using the Cold Cube on boats, if the
Cold Cube is powered by 110-240 V AC, ensure that
the power supply has a residual current circuit
breaker! Check that the voltage specification on the
type plate is the same as that of the power supply.
Only connect the Cold Cube as follows:
• with the 12/24 V connection cable included with the
Cold Cube to a 12/24 V battery.
•or, with the 110-240 V connection cable included with
the Cold Cube to the 110-240 V AC supplys.
If the cable is damaged, it must be replaced to
prevent possible electrical hazards.
Disconnect the connection cable before cleaning
and maintenance, after use and before changing a
fuse.

Safety Precautions
8
CAUTION: Danger of injuries! Batteries contain
aggressive and caustic acids. Avoid battery fluid
coming into contact with your body. If your skin
does come into contact with battery fluid, wash the
part of your body in question thoroughly with water.
Disconnect the Cold Cube and other electric devices
from the battery before you connect the battery to a
quick charging device. Over-voltage can damage
the electronics of the Cold Cube.
CAUTION: Electronic devices are not toys! The
Cold Cube is not intended for use by young children
or infirm persons unless they have been adequately
supervised by a responsible person to ensure that
they can use the appliance safely. Young children
should be supervised to ensure that they do not play
with the appliance.
Do not operate the Cold Cube if it is visibly
damaged.
The Cold Cube may only be repaired by qualified
personnel. Inadequate repairs can cause
considerable hazards. If your Cold Cube should
need repairing, please contact Euroengel customer
service.
Do not open the refrigerant circuit under any
circumstances!
The Cold Cube is not suitable for transporting
caustic materials or materials containing solvents.
Food may be stored in its original packaging or in
suitable containers.

Safety Precautions
9
WARNING: Control circuits used in the Cold Cube
are low voltage. This voltage potential is not
considered dangeous, but the large amount of
current available can cause severe burns if shorted
to ground.
WARNING: Do not wear jewelry, watches, or rings.
These items can short out electrical circuits and
cause severe burns to the wearer.
CAUTION: Use tools with insulated handles that
are in good condition.
CAUTION: Danger of fatal injury from electric
shocks!
Do not touch exposed cables with your bare hands.
This especially applies when operating the Cold
Cube from an AC power supply.
Before starting the Cold Cube, ensure that the
power supply line and the plug are dry. Do not place
any electrical devices inside the cooling container.
Set up the Cold Cube in a dry location where it is
protected against splashing water. Protect the Cold
Cube and the cable against rain and moisture. Do
not place it near open flames or other heat sources
(heaters, direct sunlight, gas ovens etc.).
CAUTION: Danger of overheating! Always make
sure there is sufficient ventilation so that heat
generated during normal operation can dissipate.
Ensure that the ventilation slots are not covered.
Leave at least 2 inches (50 mm) from top and
around the Cold Cube to ensure adequate
ventilation.
Never immerse the Cold Cube in water. Do not fill
the inner container with ice or fluid.
