Fuse thermostat
The fuse thermostat is set at the factory at a
temperature above the chamber work tempera-
ture. When it triggers, it stops the machine. In
order to reset it, it has to be replaced by the
technical assistance service.
• If the machine switches on, this shows
that the fuse thermostat is working cor-
rectly.
Key to lock handle
This key ensures that the machine cannot be
opened either accidentally or on purpose by
unauthorized personnel. The chamber may be at
very high or very low temperatures.
• Close the door, remove the key and
check that the door will not open.
Other safety systems concerning the
cooling system cannot be checked or set by
the user and are, therefore, described in
chapters 11 and 12.
