- WARNING: Keep ventilation openings in the appliance enclosure or in the built-in structure clear of
obstructions.
- WARNING: Do no use mechanical devices or other means other then those recommended by the
manufacturer, to accelerate the defrosting process.
- WARNING: Do not damage the refrigerant circuit (applicable only for appliances with refrigeration circuits
which are accessible to the user).
- WARNING: Do not use electrical appliances inside the food storage compartments, unless they are of
the type recommended by the manufacturer.
Excessive vibration may occur in the following
cases:
a) The refrigerator is not well positioned and
adjusted.
b) The refrigerator is placed on a wood floor or near
wooden furniture.
The liquid refrigerant flowing into the evaporator may
produce a slight sound similar to that of flowing water.
When the refrigerator is stopped, the backflow
refrigerant may also generate this sound.
