4 Safety instructions

DANGER! Electrocution hazard
On boats: If the device is powered by the mains, ensure that the power supply has a residual current device (RCD), a residual current circuit breaker (RCCB), or a ground fault circuit interrupter (GFCI). Installation, especially in potentially damp areas, must be in accordance with all applicable installation regulations. Do not touch exposed cables with your bare hands. This applies especially when operating the device from the AC mains. Before starting the device, ensure that the power supply line and the plug are dry.

WARNING! Explosion hazard
Do not store any explosive substances such as spray cans with a flammable propellant in the cooling device.

WARNING! Electrocution hazard
Do not operate the cooling device if it is visibly damaged.

If the cooling device's power cable is damaged, it must be replaced with a suitable power cable or assembly available from the manufacturer or its service agent to prevent safety hazard. This cooling device may only be repaired by qualified personnel. Improper repairs can lead to considerable hazards. Plug the device to sockets that ensure proper connection especially when the device needs to be earthed.
WARNING! Fire hazard
When positioning the cooling device, ensure that the supply cord is not trapped or damaged. Do not locate multiple portable socket-outlets or portable power supplies at the rear of the device. In the event of any damage to the refrigerant circuit:
- Keep open flames and potential ignition sources away from the cooling device.
- Ventilate the room well.
- Switch off the cooling device.
For cooling devices with flammable refrigerant: The refrigeration circuit contains a small quantity of an environmentally friendly but flammable refrigerant. It does not damage the ozone layer and does not increase the greenhouse effect. Any leaking refrigerant may ignite. Keep the ventilation openings on the device housing or in installations free of obstructions. Do not use any mechanical objects or other means to speed up the defrosting process, unless they have been recommended by the manufacturer for this purpose. Do not open or damage the refrigerant circuit. Do not use electrical devices inside the cooling device unless they are recommended by the manufacturer for that purpose.

WARNING! Health hazard
This cooling device can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the cooling device in a safe way and understand the hazards involved. Children aged from 3 to 8 years are allowed to load and unload cooling devices.
Children must be supervised to ensure that they do not play with the device. Cleaning and user maintenance must not be carried out by unsupervised children.

CAUTION! Electrocution hazard
Before starting the cooling device, ensure that the power supply line and the plug are dry. Disconnect the cooling device from the power supply
• Before each cleaning and maintenance
• After every use

CAUTION! Health hazard
To avoid contamination of food, observe the following instructions:
- Check if the cooling capacity of the cooling device is suitable for storing the food to be cooled.
- Food may only be stored in its original packaging or in suitable containers.
- Opening the cooling device for long periods of time can cause significant increase of the temperature in the compartments of the device.
- Clean regularly surfaces that can come in contact with food and accessible drainage systems.
If the cooling device is left empty for long periods:
- Switch off the cooling device.
- Defrost the cooling device.
- Clean and dry the cooling device.
- Leave the lid open to prevent mold from developing within the cooling device.

NOTICE! Damage hazard
Check that the voltage specification on the data plate corresponds to that of the energy supply. Only connect the cooling device as follows:
- With the DC connection cable to a DC power supply in the vehicle
- 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 open 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. The cooling device shall not be exposed to rain.

6 Operation
6.1 Avoiding food waste
To avoid food waste, note the following:
Keep temperature fluctuation as low as possible. Only open the cooling device as often and for as long as necessary. Store the foodstuff in such a way that the air can still circulate well. Adjust the temperature to the quantity and type of the foodstuff. Foodstuff can easily absorb or release odor or taste. Always store foodstuff covered or in closed containers/bottles.
6.2 Saving energy
Choose a well ventilated location which is protected from direct sunlight. Allow warm food to cool down first before placing it in the cooling device to keep cool. Do not open the cooling device more often than necessary. Do not leave the cooling device open for longer than necessary. If the cooling device has a basket: For optimal energy consumption, position the basket according to its position on delivery. On a regularly basis, ensure the lid seal still fits properly. Avoid unnecessarily low temperatures.
