Adjusting the refrigerator feet
Your refrigerator is equipped with 2 wheels that provide great ease in placing, moving
and cleaning the appliance.
You can easily block the front wheels by turning the feet in front of them to the left, in
order to prevent any undesired movement of the refrigerator. Thus, back and forth
movement during opening or closing the door is avoided and a more level placement
is achieved.
You can unlock the front wheels by turning the feet in front of them to the right, in order
to clean or move your refrigerator.
