5. ANTIFREEZE DEVICE FOR humiDisk

65
The antifreeze device is required when the humiDisk is installed in an environment where the tempera-
65
ture may drop below 0°C.
IMPORTANT: observe the operating limits shown Tab. 11.b.
If this happens, in fact, ice may form inside the appliance and affect correct operation. The appliance is
already designed to fi t the antifreeze kit, and this can be installed in a few minutes. The device consists
of an electric heater, the operation of which is controlled by the electronic board and by the connected
temperature sensor. The heater is enabled when the temperature inside the appliance approaches 0°C.
In this way, a fl ow of warm air is generated, which prevents the formation of ice, allowing the humiDisk to
65
operate at temperatures of down to -2°C.
Below this temperature the use of the appliance is not advisable, due to the actual operating principle of
the unit.
When the temperature inside the appliance rises above +2.5°C, the electronic board disables the heater
so as to save energy.
The heater has been designed for safety, and if the thermostat device should malfunction, it will never reach
dangerous temperatures.
IMPORTANT: the units with code UC0650D100 already include the antifreeze heater kit as standard, while
for the code UC0650D000 versions, the heater kit code UCKH70W000 can be fi tted as an option .
