Connecting the refrigerator to DC voltage

NOTICE! DANGER OF DAMAGE

• To avoid voltage drops and loss of performance, keep the connection cable as short as possible and not be interrupted. Therefore avoid additional switches, plugs, power strips or Power bar.
• Disconnect the cooling device and other electric consumers from the battery before you connect the battery to a quick-charging device. Overvoltage can damage the electronics of the device.

The refrigerator can be operated with 12 or 24 VDC voltage supply. For safety reasons, the refrigerator is equipped with an electronic system to prevent the polarity from being reversed. This protects the refrigerator against reversed polarity when connecting to a battery and against short-circuiting. To protect the battery, the refrigerator switches off automatically if the voltage is insufficient (see table below).

Determine the required cross section of the cable in relation to the cable length according to fig.11.

NOTICE! DANGER OF DAMAGE

Make sure the polarity is correct.

• Before starting up the device for the first time, check whether the operating voltage and the battery voltage match (see type plate).
• Connect your refrigerator to a plug socket that is fuse-protected at 15 A (at 12 V) or 7.5 A (at 24 V) (fig.12).
• Connect the red cable (fig.12, Page 6) to the positive terminal of the battery.
• Connect the black cable (fig.12, Page 6) to the negative terminal of the battery.

Connecting the refrigerator to AC voltage

DANGER! DANGER OF ELECTROCUTION

• Never handle plugs and switches with wet hands or if you are standing on a wet surface.
• If you are operating your refrigerator on board a boat with an AC mains connection using a shore connection, you must install a residual current circuit breaker between the AC mains supply and the refrigerator. Seek advice from a trained technician.

Using the refrigerator

The refrigerator conserves fresh foodstuffs. The freezer compartment conserves frozen foodstuffs and freezes fresh foodstuffs.

NOTICE!
DANGER OF DAMAGE

• Do not place any electrical devices inside the cooler. The only exceptions are devices approved for the purpose by the manufacturer.
• Ensure that food or liquids in glass containers are not excessively refrigerated. Liquids expand when they freeze and can therefore destroy glass containers.
• Food may only be stored in its original packaging or in suitable containers.
• Make sure that you only put items in the cooler which may be kept at the selected temperature.

NOTE！

• Before starting your new refrigerator for the first time, you should clean it inside and outside with a damp cloth for hygienic reasons (please also refer to the chapter“Cleaning and maintenance”on Page 33).
• Do not use force to press the flap of the freezer.
• Do not pull out the dividing wall if there is ice in the freezer.
• Do not remove the control panel membrane when operating the refrigerator.

Energy saving tips

• Choose a well-ventilated location that is protected from direct sunlight.
• Allow hot food to cool down first before you put it in the refrigerator.
• Do not open the refrigerator more often than necessary. If the door is left open for more than 5 minutes, the light starts to flash.
• Do not leave the door open for longer than necessary.
• Defrost your refrigerator as soon as a layer of ice forms.
• Avoid unnecessarily low temperature settings.
• Clean dust and dirt from the condenser at regular intervals.

Switching on the refrigerator

• Switch the refrigerator on by pressing the button.

NOTE！
After switching on, the refrigerator needs some time before the compressor starts up.

• Turn on the quite mode: Press and hold the on/off button and the temperature selection button simultaneously, then the orange light flashes three times to turn on the quiet mode.
• Turn off the silent mode: Press and hold the on/off button and the temperature selection button simultaneously, then the blue light flashes three times to turn off the quiet mode.

Setting the temperature

• Press the button repeatedly until the desired temperature level is set. The lower/largest LED is the coldest setting. The upper/smallest LED is the warmest setting. To switch from the coldest level 5 to the warmest level 1 press the  button again.

NOTE！
The cooling performance can be affected by:

• The ambient temperature.
• The amount of food to be conserved.
• The frequency with which the door is opened.

If the ambient temperature is at 16°C (61°F) to 20°C (68°F), set the refrigerator to at least level 2.

Conserving foodstuffs

NOTICE!
DANGER OF DAMAGE

• Do not conserve warm foodstuffs in the refrigerator.
• Do not place glass containers containing liquid in the freezer compartment.

NOTE！
Food which can easily absorb tastes and odors, as well as liquids and products with a high alcohol content, should be conserved in airtight containers.

You can conserve foodstuffs in the refrigerator. The time for which the food can be conserved in this way is usually stated on the package. The refrigerator is divided in different zones with different temperatures:

• The colder zones are immediately above the drawers for fruit and vegetables, near the back wall.
• Observe the temperature information and best-before date on the food packaging.
• Observe the following when using the refrigerator:
  • Never re-freeze products that have started defrosting or have been defrosted; consume them as soon as possible.
  • Wrap food in aluminum foil or cling film and shut in a suitable box with a lid.

This ensures that aromas, the shape and freshness will be better conserved.

Defrosting the freezer

NOTICE! DANGER OF DAMAGE
Never use mechanical tools to remove ice or to loosen objects stuck to the device. The only exceptions are devices approved for the purpose by the manufacturer.

This is how to defrost the refrigerator:

• Empty the contents.
• If necessary, put them in another cooling device to keep them chilled.
• Press the button until the refrigerator switches off.
• Close the door properly.

Switching off and storing the refrigerator

If you do not intend to use the refrigerator for a long time, proceed as follows:

• Press the  button until the refrigerator switches off.
• Disconnect power.
• Clean the refrigerator (see chapter“Cleaning and Maintenance).
