# Important Information
Every 6 hours
an
automatic defrosting operation
takes place, which prevents the evaporator
from icing up. The defrosting phase takes around
20 minutes
when the power to the appliance is
switched on
.
The
defrosting
LED (3) lights up.
If the power supply is interrupted, for example during transport, this interruption time must also be
taken into account. After switching on again/switching on the power supply, the defrost phase
continues.
The time should not be extended if cooling is unavailable. Take note of the
defrosting operation display (3). Comply with the HACCP regulations.
