INSTALLATION
Before proceeding to the operations of installation, maintenance and reparation of
the machine, read the manual carefully, where there is contained the necessary
information for the correct use of the machine.
Install the machine in a dry and not dusty place.
Put to level the machine through the regulation of the feet.
ELECTRIC CONNECTION
Before connecting the machine to the power, follow the following instructions:
o check that the electric line has a suitable course for the absorbed power
(1600W)
o check that the voltage corresponds to the data indicated in the plate on the left
side of the machine.
o The power has to have the efficient earth connection..
o In case of substitution of the cable of feeding, use only original cables (ask to
the manufacturer the special cable with type M connection)
The manufacturer will not take on any responsibility if these instruc-
tions are not respected.
All the electric devices in the machine work with a 24Vdc produced by the trans-
former except the boiler heating element and the same transformer, that use a ten-
sion of 230Vac or 120Vac on request.
The main light switch is a bipolar type and it supplies all the machine.
There are two fuses, 2A and 12A, which respectively protect the transformer and
the circuit in low voltage 24Vdc.
In case you have to extract the breakdown fuses, unscrew the hood container.
The 20Vac low-power circuit is interrupted by a safety button, situated on the
chassis, that cuts the current to the electronic board when the door is open.
Extracting the button, it is possible to reestablish the feeding with the door open
(by only technical staff).
