User Manual Neff KI5872F30G 50 Built-in Fridge-Freezer 

This depends on the size, age and model of the refrigerator. It may take several hours to 24 hours for the refrigerator to reach the set temperature. The process can be accelerated by placing non-perishable goods in the refrigerator. The temperature in the refrigerator cannot be measured properly by feeling the air inside. The best way to tell if the refrigerator has reached the set temperature is to place a glass of water in the refrigerator with a thermometer in it.

No, the fridge-freezer needs to stand in an upright position for at least 4 hours before it can be turned on. This is because the coolant liquid needs to settle.

There are special cleaning devices to do this, but it is also possible to remove blockage or dirt with a cotton swab. To keep the drain hole clean and prevent smells it is advisable to put a drop of chlorine bleach in the drain 4 times a year.
