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 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.

❗ WARNING! Electrocution hazard

Do not operate the cooling device if it is visibly damaged. If this cooling device's power cable is damaged, it must be replaced to prevent safety hazards. 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 device, ensure 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. The refrigerant in the refrigerant circuit is highly flammable and in the event of a leakage combustible gases could build up if the appliance is in a small room. In the event of any damage to the refrigerant circuit:

• Keep naked flames and potential ignition sources away from the refrigerator.
• Ventilate the room well.
• Switch off the refrigerator.

For cooling devices with R600a 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.
• Do not use or store the cooling device in confined spaces with none or minimal air flow. Keep the ventilation openings on the device housing or in installations free of obstructions. Do not use any mechanical objects or other media 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 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 device in a safe way and understand the hazards involved. Children aged from 3 to 8 years are allowed to load and unload refrigerating devices. Children must be supervised to ensure that they do not play with the device. Cleaning and user maintenance shall not be made by children without supervision.

❗ WARNING! Explosion hazard

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

? CAUTION! Electrocution hazard

Before starting the cooling device, ensure that the power supply cable and the plug are dry. Disconnect the cooling device from the power supply before each cleaning and maintenance and aer every use.

? CAUTION! Health hazard

To avoid contamination of food, respect the following instructions:

• Check if the cooling capacity of the device is suitable for storing the food you wish to cool.
• Food may only be stored in its original packaging or in suitable containers.
• Opening the cooling device for long periods 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 device is le empty for long periods:

• Switch off the device.
• Defrost the device.
• Clean and dry the device.
• Leave the lid open to prevent mould developing within the device.

ℹ️ NOTICE! Damage hazard

Check that the voltage specification on the type 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
• 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 you turn off the engine. Otherwise you may discharge the battery. 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.). 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. To enable the refrigerant to circulate properly, the cooler may not tilted by more than 30 . Use a spirit level to ensure the cooler is level. Risk of overheating! Ensure at all times that there is sufficient ventilation on all four sides of the cooling device. Keep the ventilation area free of any objects that could restrict the air flow to the cooling components. Do not place the cooling device in closed compartments or areas with none or minimal air flow.
