Notes on defrosting

The NoFrost system automatically defrosts the appliance. Any moisture arising collects on the evaporator and freezes, and is periodically defrosted and evaporated.

The automatic defrosting system keeps the freezer frost- free and eliminates the time and effort spent on defrosting manually.

Cleaning

WAlways disable the appliance for cleaning. Dis- connect from the mains or unscrew or switch off the fuse.

WClean the outer walls, inside and equipment by hand with lukewarm water and a little detergent. Because of the risk of injury and damage to the appliance, steam cleaning equipment should not be used.

WWe recommend using a soft cloth and an all-purpose cleaner with a neutral pH value. Only use food compati- ble cleaning and care agents on the inside of the appli- ance.

WUse a commercially available stainless-steel cleaning agent for stainless-steel appliances*.

- In order to achieve best possible protection, apply a stain- less-steel care agent uniformly in grinding direction after cleaning. Points which are darker at the start and a more intensive coloration of the stainless-steel surface are nor- mal.

- Do not use abrasive sponges or scourers, do not use con- centrated cleaning agents and never use cleaning agents containing sand, chloride or acid or chemical solvents, as these would damage the surfaces and could cause corro- sion.

WEnsure that no cleaning water is allowed to penetrate into the electrical components or ventilation grilles.

Dry the appliance.

-Do not damage or remove the type plate on the inside of the appliance as this is important for customer service.

WThe dust should be removed from the refrigeration unit and heat ex- changer - metal grid at the back of the appliance - once a year. Dust deposits increase energy consump- tion.

WEnsure that none of the wires or other components are dislodged, bent or damaged.

WThen connect/switch on the appliance, switch on Super- Frost and start to insert the food to be frozen as the temperature drops.

If the appliance is to be left out of operation for any length of time, empty it, disconnect from the mains, clean as described above and leave the door open in order to avoid unpleasant smells.

Your appliance is designed and manufactured for a long life span and reliable operation.

If a malfunction nonetheless occurs during operation, check whether it is due to an operating error. Please note that even during the warranty period the resultant servicing costs in this case will have to be borne by the owner.

You may be able to rectify the following faults by checking the possible causes yourself

Malfunction - Possible cause and remedy

______________________________________________________

Appliance does not work

-Is the appliance switched on properly?

-Is the mains plug properly inserted in the socket?

-Is the socket fuse intact?

Loud running noise

-Is the appliance standing firmly on the floor, or does the compressor cause nearby items of furniture or objects to vibrate?

If necessary, move the appliance slightly, align by adjust- ing the adjustable feet, or move bottles and containers apart.

-Burbling noises are normal. These are caused by the

refrigerant flowing round the refrigerant circuit.

A short clicking sound: This will be heard whenever the refrigeration unit (the motor) switches on or off automati- cally.

Motor noise: This will be slightly louder for a brief period when the refrigeration unit switches on.

The audible warning signal sounds, the red audible warning on/off button is lit, the temperature is not cold enough

-Have you put too much fresh food into the freezer without activating SuperFrost? (See "SuperFrost")

-Does the door close properly?

-Is the appliance sufficiently well ventilated? Clear ventilation grilles if necessary.

-Is the ambient temperature too hot? (See "Safety regula- tions")

-Has the appliance been opened too often or left open too long?

-If applicable, wait until the appliance reaches the required temperature itself.

The outside of the appliance may feel warm in places

-That is quite normal. The heat from the cooling circuit is used to avoid the formation of condensate.
