9 SPECIAL FUNCTIONS
9.1 Manual defrosting
To carry out the test cycle and maintenance, a new manual defrosting procedure has been introduced, which
has to be performed by cold internal temperature (to avoid the possible opening of the thermal switches of the
defrosting heater.
To start the manual procedure operate as follows:
• open the cooler door
• hold down the temperature selection button
• push the cooler door button for 5 times within a 6-second interval
At this point the electronic board:
• activates the buzzer that emits a long beep
• switches on and off the two groups of LEDs of the temperatures (+2 +5 +8) and (+4 +6) alternatively
In this case the electronic PCB performs the standard defrosting cycle: when the cycle has come to the end,
the appliance starts operating normally.
