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).
  • The door stays open thus preventing smells from arising.

If the fuse in the AC socket is faulty, it can be replaced.

  • Lever the fuse compartment (fig.13) open with a screwdriver.
  • Replace the fuse (250 V/4 A).
  • Close the fuse compartment again.3J-SVR-Series-Compressor-Refrigerator-fig-13

Cleaning and maintenance

NOTICE!
DANGER OF DAMAGE

  • Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the refrigerator.
  • Do not use hard or pointed tools to speed up the defrosting process.
  • Always disconnect the device from the power supply before you clean and service it.
  • Clean the refrigerator regularly and as soon as it becomes dirty with a damp cloth.
  • Make sure that no water drips into the seals. This can damage the electronics.
