6.6. Safety Devices

Overload protection device: will trip if maximum current intensity (A) is exceeded, hence
preventing the motor from overheating due to current peaks. When overload trips, a red light
will switch on in the front panel. The overload must be reset manually, to do so the front
grille and overload cover must be removed.

Thermal protection device: will trip if temperature in motor exceeds set point. When this
device trips, the same red light will switch on in the front panel. In this case, however, reset
is automatic.

Low water level sensor: a magnetically activated sensor (buoy) located inside the water
trough will switch off the machine should the level of water fall below the set minimum. A red
light will switch on in the front panel labelled
“low water level”. Reset is automatic.

Bin full of ice: a micro-switch located at the top of the evaporator will stop the machine when
the bin (and the ice discharge tube leading to the bin) is full of ice. An orange light will
switch on in the front panel labelled
“bin full”. Reset is automatic.
