WARNING Before cleaning, always disconnect the appliance from the mains. Pull out the plug or switch off the fuse. WARNING Risk of electrostatic discharge. Only clean plastic parts with a damp cloth! CAUTION Risk of damage to the appliance components and risk of injury due to hot steam. Do not use steam cleaning equipment to clean the appliance. NOTICE All surfaces in the appliance must be cleaned at regular intervals! • Clean the inside, equipment parts and outer walls with lukewarm water and a little detergent. Do not use chemical solvents or any cleaning agents containing sand or acid. • To avoid short-circuits, ensure no cleaning water penetrates into the electrical components when cleaning the appliance.
The lock in the appliance door is equipped with a safety mechanism.
• Dry all parts well with a cloth.
Locking the appliance
• Do not damage or remove the type plate on the inside of the appliance. It is very important for servicing purposes.
• Insert the key as shown by arrow 1. • Turn the key 90°. To unlock the appliance, the same procedure must be repeated in the same order.
Defrosting
After a longer period of operation a layer of frost or ice can build up on the cooling plates in the freezer compartment. This will increase the energy consumption of the freezer. The cooling plates should therefore be defrosted regularly. • To defrost, switch the appliance off. Pull out the mains plug. • Remove the drawers.
• Transfer items to other appliances.
• Leave the door of the appliance open while defrosting. After defrosting mop up the remaining water with a cloth and clean the appliance.
22
Cleaning
• The dust should be removed from the refrigeration unit and heat exchanger - metal grid at the back of the appliance - once a year.
Disposal notes
The appliance contains reusable materials and should be disposed of properly - not simply with unsorted household refuse. Appliances which are no longer needed must be disposed of in a professional and appropriate way, in accordance with the current local regulations and laws. Do not damage the refrigerant circuit of an appliance that is no longer needed during its disposal. This appliance contains inflammable gases in the refrigerant circuit and insulation foam. Your local council or a waste disposal contractor can provide information about how to dispose of the appliance correctly.
Shutting your appliance down
If the appliance is left empty for a lengthy period, it must be switched off, defrosted, cleaned and dried and the door is to be left open to prevent mould formation.
Malfunctions
You may be able to rectify the following faults by checking the possible causes yourself: • Appliance does not function: – Is the appliance switched on? – Is the plug correctly fitted in the mains socket? – Is the fuse intact? • The temperature is not low enough: – Is the temperature setting correct (see "Setting the temperature")? – Does the separately installed thermometer show the correct reading? – Is the ventilation system working properly? – Is the appliance set up too close to a heat source?
EN
External alarm
There are various connection options at the back of the appliance.
The appliance may only be connected to an external alarm device by trained personnel.
Note The connectors are secured with screws. To remove the connectors, undo the left and right screws.
• Temperature alarm test does not work as required. – See „Alarm test“ and „Adjusting the alarm parameters“ If none of the above causes apply and you cannot rectify the fault yourself, contact the nearest customer service department stating the type designation 1, service number 2 and appliance number 3as indicated on the type plate.
