Thanks for the good service

Please note that the tray shown in the figure is not an accessory. If the frost or ice layer is too thick for removal with the spatula, defrosting will be necessary. The frequency of defrosting depends on the actual use. To defrost the product: Set the thermostat to position << >>. Disconnect the product from the mains. After removing them from the freezer, place the frozen foods in a basket padded with paper or cloth and kept in a cool place, or relocate them into the deep-freezing or cooling compartment of a normal fridge. Leave the door open. From time to time use a cloth or sponge to sweep off laterally the defrost water so that it can be collected in a drain at the bottom of the product and then remove the water as follows: Place a tray of sufficient height in front of the product. Following the arrow, carefully pull out the defrost water drain, located in the central bottom section of the product, to let the defrost water flow into the tray. The defrosting process will be quicker if you put a pan filled with hot water on the cooling plates used as shelves.
Once defrosting is completed, dry the wet surfaces and push back the defrost water drain. Connect the product to the mains. Rotate the thermostat to position <<18°C>> and let the product operate in quick freeze mode for at least 2 hours before putting back the formerly removed frozen foods.
Regular cleaning
It is practical to clean the inside of the freezer and defrost it at a time. Household cleaner or soap must not be used. After breaking the circuit wash the appliance using lukewarm water and wipe it. Clean the door gasket with clean water. After cleaning apply voltage to the appliance. It is recommended to remove the dust and dirt collected on the back of the appliance and the condenser once or twice a year.
Long-term abscence
If you do not use the product for longer periods, make sure to perform the following: Set the thermostat to position << >>. Disconnect the product from the mains. Remove all foods from the product. Perform defrosting and cleaning operations as described above. Leave the doors ajar to avoid the build-up of unpleasant odors.
