5 Technical description

The cooling box is portable. The cooling box can keep goods cool up to max. 30 °C below ambient temperature.

5.1 Connections

5.2 Control elements

When the cooler is connected to the AC mains, the required cooling level is set using the cooling level controller for AC operation ( 1 ).

To increase the cooling level, turn the cooling level controller ( 1 ) clockwise.
For the maximum cooling level, turn the cooling level controller ( 1 ) clockwise as far as it will go.
To decrease the cooling level, turn the cooling level controller ( 1 ) anticlockwise.
To switch the cooler off, turn the cooling level controller ( 1 ) anticlockwise as far as it will go.

When the cooler is connected to the DC power socket the cooling level cannot be adjusted.

When the cooler is operated with gas, the required cooling level is set using the cooling level controller for gas operation ( 2 ).
To increase the cooling level, turn the cooling level controller ( 2 ) clockwise.
For the maximum cooling level, turn the cooling level controller ( 2 ) to the maximum position.
To decrease the cooling level, turn the cooling level controller ( 2 ) anticlockwise.
To switch the cooler off, turn the cooling level controller ( 2 ) anticlockwise as far as it will go.

6 Operation

  NOTICE! Damage hazard

• Ensure that the items placed in the cooler are suitable for cooling to the selected temperature.
• Ensure that food or liquids in glass containers are not excessively refrigerated. Liquids expand when they freeze. and can therefore destroy glass containers.
• Ensure that your refrigerated container is well ventilated so that any heat created can dissipate. Otherwise proper functioning cannot be ensured. It is especially important not to cover the air vents.

  NOTE

• Cool the cooler for about 24 hours before starting your journey using gas or electricity from the mains. This way your cooler will attain the required cooling level faster when you reach your destination.

• The cooling performance can be affected by:
  – the ambient temperature
  – the amount of food to be conserved
  – how often the lid is opened.

• A few water drops may form inside the cooler if it has been cooling for a lengthy period. This is normal because the moisture in the air condenses to water when the temperature in the cooler falls. The cooler is not defective. Wipe it out with a dry cloth if necessary.

Before starting your new cooler for the first time, clean it inside and outside with a damp cloth for hygienic reasons (see also chapter “Cleaning and maintenance”).
Press the control element cover (fig. 2 3 and fig. 3 3) to open it.
To close the control element cover (fig. 2 3 and fig. 3 3,), push it towards the lid until it latches.
Fill up the base of the cooling box first when storing drinks, etc.

6.1 Storing food

To avoid food waste, note the following:

• Keep temperature fluctuation as low as possible. Only open the cooling box 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 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.

6.3 Using the cooler in DC mode

Proceed as follows (fig. 6 ):

1. Place the cooler on a firm, level surface.
2. Plug the DC connection cable (fig. 2 1 and fig. 3 1 ) into the DC socket in the vehicle.

√ The cooler starts cooling the interior.
Pull out the DC connection cable to switch off the cooler

6.4 Connecting to vehicle power

NOTE
If you connect the cooling device to the vehicle power, remember that you may have to turn on the ignition to supply it with power.

6.5 Using the cooler in AC mode

Proceed as follows (fig. 7 ):

1. Place the cooler on a firm, level surface.
2. Plug the AC connection cable (fig. 2 2 and fig. 3 2) into the AC mains.

9 Troubleshooting

the device is horizontal. Check if the ventilation of the device is sufficient.
The refrigerant circuit is defective.| This can only be repaired by an authorised repair centre.
IN DC mode: The cooler is not working (plug is inserted).| No voltage is flowing from the DC power socket in your vehicle.| The ignition must be switched on in most vehicles to supply current to the DC power socket.
The DC socket is dirty. This results in a poor electrical contact.| If the plug of your cooler becomes very warm in the DC socket, either the socket must be cleaned or the plug has not been assembled correctly.
The fuse of the DC plug has blown.| Replace the fuse of the DC plug with one of the same rating.
The vehicle fuse has blown.| Replace the vehicle fuse in the DC socket (usually 15 A) (Please refer to the operating manual of your vehicle).
In AC mode: The cooler is not working (plug is inserted).| No voltage present in the AC socket.| Try using another plug socket.
In gas mode: The cooler is not working (the cooler is connected to the gas).| The cooler is not properly connected to the gas.| Check if the gas supply is in full working order.
Check if the valve on the gas bottle is open.
Check if there is still gas in the bottle.
Check if several energy sources are connected at the same time.
Hold down the cooling level controller longer to ignite the flame.
The cooler does not start up after a long period of inactivity| –| Disconnect the device from the power supply, turn it upside down and wait for five minutes.
Turn the cooler the right way up again and switch it on again.

10 Disposal

Place the packaging material in the appropriate recycling waste bins, wherever possible.
