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 ColdCube
operating parameters.
CAUTION: Danger of fatal injury from electric
shocks! When using the ColdCube on boats, if the
ColdCube 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 ColdCube as follows:
• with the 12/24 V connection cable included with the
ColdCube to a 12/24 V battery.
•or, with the 110-240 V connection cable included with
the ColdCube 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 ColdCube 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 ColdCube.
CAUTION: Electronic devices are not toys! The
ColdCube 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 ColdCube if it is visibly
damaged.
The ColdCube may only be repaired by qualified
personnel. Inadequate repairs can cause
considerable hazards. If your ColdCube should
need repairing, please contact Thermo King
customer service.
Do not open the refrigerant circuit under any
circumstances!
The ColdCube 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 ColdCube
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
ColdCube from an AC power supply.
Before starting the ColdCube, ensure that the power
supply line and the plug are dry. Do not place any
electrical devices inside the cooling container.
Set up the ColdCube in a dry location where it is
protected against splashing water. Protect the
ColdCube 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 ColdCube to ensure adequate
ventilation.
Never immerse the ColdCube in water. Do not fill
the inner container with ice or fluid.

Connecting to a DC battery
For safety reasons, the cooling container is equipped with an
electronic system to protect it against reversed polarity when
connecting to a battery.
The ColdCube is supplied with a standard length DC battery
cable with a fuse on the positive side. If this cable cannot be
used, the fuse must be transferred to the cable installed.
Determine the required cross section of the cable in relation to
the cable length according to the following table:
Cable Length, 12 V & 24V DC
NOTE: If the vehicle is equipped with a battery
disconnect switch, always wire the ColdCube after
the switch. This allows power to the ColdCube to be
turned off by the battery disconnect switch.
CAUTION: Danger of damaging the ColdCube!
Over-voltages can damage device electronics.
Disconnect the cooling container and other
consumers from the battery before charging the
battery with a quick charging device.
CAUTION: Danger of damaging the ColdCube! To
prevent voltage and power losses, the cable should be
as short as possible and not be interrupted. For this
reason avoid additional switches, plugs or socket
strips

Low Voltage DC Protection
The ColdCube is equipped with a battery monitor that protects
the compressor from low voltage when connected to DC
power. Thermo King has set the compressor low voltage
disconnect higher than required to provide partial battery
protection. If the ColdCube is operated when the vehicle
ignition is switched off, the compressor switches off
automatically as soon as the supply voltage falls below a set
level. The compressor will switch back on once the battery has
been recharged to the restart voltage level (normally 1.3V
higher than the cut-out value).
Before starting up the ColdCube for the first
time, check whether the operating voltage
and the battery voltage match (see type
plate).
Make sure that the cable at the positive
battery terminal is protected with a fuse.
See Figure 3.
Fuse Sizes:
• 140 Litre cooling: 15A
• 140 Litre freezing: 25A
• 330 Litre cooling: 15A
• 330 Litre freezing: 25A
• 915 Litre cooling: 25A
• 915 Litre freezing: 25A
NOTE: The battery monitor only switches
the compressor off and not the fans or
controller, therefore a residual draw of
1 to 1.5 amps on the battery will remain
unless the ColdCube power switch is turned
off.
We highly recommend installing an ignition
switch relay to turn off the ColdCube when
the vehicle is not running.

ColdCube Installation
17
Connecting to a 110-240 VAC Power
Source
The ColdCube has a built-in multi-voltage electrical
connection adapter with a priority circuit for connecting to a
110-240 VAC supply. The priority circuit automatically
switches to VAC operation if the ColdCube is connected to a
110-240 VAC supply, even if the 12/24 V cable is still
connected.
If both power sources are connected, AC power is selected. If
the AC power supply is disconnected or drops below 85 V AC
there will be a one minute time delay before the compressor
switches to operate on DC power. If AC power is established at
any time, there will be no delay to compressor operation.
CAUTION: Danger of electrocution! Never handle
plugs and switches with wet hands or if you are
standing on a wet surface.
Plug the AC connection cable into the
AC voltage.
