8 Maintenance and repair
WARNING
• Before cleaning or carrying out maintenance work, always switch the machine off and disconnect the
mains plug. Working on the connected appliance may cause electric shock or fire.
• When disconnecting, always pull the plug and never the cable. Pulling the cord may result in electric
shock or fire due to a short circuit.
• During defrosting, water will leak from the unit. Collect this water so that it does not lead to a risk of
slipping for passing persons.
• Watch out that no water can penetrate the ventilation slots of the unit.
• Before cleaning or carrying out maintenance work, the contents preserved in it will have to be removed
and stored temporarily in another working refrigerator.
• Make sure the condensation water is removed on a weekly basis. Increased condensation water inside
the device may lead to malfunctioning of the device.
• Inspect the unit on a regular basis for damaged parts. Only genuine spare parts may be used. Use of
any other parts may affect the performance or cause physical injury or damage to the equipment.
CAUTION
• The use of hydrogen peroxide H2O2 (VHP) for the disinfection (sterilization) of the appliances is not suit-
able. This procedure may be applied exclusively with dedicated appliances.
• Other than the cleaning procedure described in this manual, follow the internal policy and procedures.
• Before using the refrigerator it should be cleaned inside and outside.
• For cleaning, use only gentle cleaning agents. Never use aggressive or caustic cleaning agents, scour-
ing powder, steel wool, abrasive sponges or chemical solvents. When cleaning, make sure that no flu-
ids of any kind run into the ventilation housing.
• For disinfecting, we recommend all the surface disinfecting agents commonly used by the customer, pro-
vided they are recommended by the national organizations. For disinfecting small areas, we recommend
using a concentrated alcoholic agent.
8.1 Cleaning
• The refrigerator should be cleaned and if necessary disinfected before you use it for the first time and
then at regular intervals thereafter.
• Only use gentle cleaning agents. Never use aggressive or caustic cleaning agents, scouring powder, steel
wool, abrasive sponges or chemical solvents. When cleaning, make sure that no fluids of any kind run
into the ventilation housing.
• Before restarting the unit after cleaning, the interior must be thoroughly dried.
8.2 Defrosting
• The moisture in the air, which enters the cabinet
due to lid opening (and also may be due to defec-
tive lid-gasket or door alignment) is attracted by
the cold surfaces inside. So, formation of frost
and ice occurs on the walls around the icepacks
inside the icepack-compartment. When the frost
layer is 6-12 mm thick, it is time for defrosting.
• Switch off the power supply and remove the plug
of its power supply cord from the wall socket.
• Prepare the temporary storage and transfer the
contents and preserve properly with care.
• Take the frozen ice packs out. Keep them
wrapped together with a thick blanket or similar
drainage
