Food safety
To avoid contaminating the wine, you must follow the instructions below:
 Leaving the door open for long periods of time may significantly raise
the temperature in the appliance compartments.
 If the refrigerator remains empty for an extended period of time, switch
it off, defrost it, clean it, dry it and leave the door open to prevent any
mould from forming inside the appliance.
