– Or with the AC connection cable to an AC power supply
• Never pull the plug out of the socket by the cable.
• If the cooling device is connected to a DC outlet, disconnect the
cooling device and other power consuming devices from the battery
before connecting a quick charging device.
• If the cooling device is connected to a DC outlet, disconnect the
cooling device or switch it off when turning off the engine. Otherwise
the battery may be discharged.
• The cooling device is not suitable for transporting caustic materials or
materials containing solvents.
• The insulation of the cooling device contains flammable cyclopentane
and requires special disposal procedures. Deliver the cooling device
at the end of its life-cycle to an appropriate recycling center.
• Do not place the cooling device near naked flames or other heat
sources (heaters, direct sunlight, gas ovens etc.).
•Risk of overheating!
Ensure at all times that there is a minimum of 50 mm ventilation on all
sides of the cooling device. Keep the ventilation area free of any
objects that could obstruct the air flow to the cooling components.
Do not use or store the cooling device in closed compartments or
areas with none or minimal air flow.
• Do not fill the inner container with ice or fluids.
• Never immerse the cooling device in water.
• Protect the cooling device and cables against heat and moisture.

• If the cooler has a basket: For optimal energy consumption, position the basket
according to its position on delivery.
• On a regular basis, make sure the lid seal still fits properly.
• Defrost the cooler once a layer of ice forms.
• Avoid unnecessarily low temperatures.
5.3 Connecting the cooler
Connecting to a battery (vehicle or boat)
The cooler can be operated with 12 V or 24 Vg.
A
For safety reasons the cooler is equipped with an electronic system to prevent
polarity reversal. This protects the cooler against short-circuiting when connecting to
a battery.
Using the fused DC plug
A
1. Plug the DC connection cable (fig. 12, page 7) into the DC voltage socket of
the cooler (fig. 44, page 12).
2. Connect the connection cable to a DC power outlet.
NOTICE! Damage hazard
Disconnect the cooler and other consumer units from the battery before
you connect the battery to a quick charging device.
Overvoltage can damage the electronics of the device.
NOTICE! Damage hazard
For protection of the device the DC cable supplied includes a fuse inside
the plug. Do not remove the fused DC plug.
Only use the DC cable supplied.
