Have any measures taken against tipping due to earthquakes?
In order to prevent the refrigerator from tipping due to earthquakes,
secure the straps to the hooks at the back of the refrigerator.
Refrigerator doors should not be opened during the
cooling process.
The doors should not be opened until interior has been
cooled down suffciently. (Warm air flowing into the interior
will block the cooling function of the refrigerator.)
Please wait until the interior has cooled down.
● It may take approximately 4 hours to cool down the
interior.
● It may take 24 hours or more to cool down the interior
and achieve equilibrium in the summer.
