4.1.4 DEFROSTING
The monobloc carries out defrost cycles at intervals pre-set by the manufacturer.
If under specific operating conditions (very hot or humid periods of the year, the introduction of produce that releases a great
deal of moisture or frequent door opening .....), the set defrost cycles are insufficient for the complete removal of ice from the
evaporator, additional "manual" defrost cycles can be carried out.
Hold down the DEFROST/UP button for more than 5 seconds in order to start a "manual" defrost cycle, which will begin only if
conditions require it.
4.1.5 STOPPING THE MACHINE
To stop the monobloc, it is sufficient to use the ON/OFF SWITCH .
If the machine is to remain switched off for long periods, it is advisable to disconnect it from the power supply mains.
