6 MACHINE UNPACKING AND INSTALLATION
ATTENTION: The unit must be installed, opened and repaired by fully qualified technicians only.
6.1 UNPACKING
Find the most suitable place where to put the machine, then remove the packaging. Make sure that the machine
has not been damaged during the transport and the storage.
The packaging material does not require any special precautions for its disposal, for it is not dangerous or polluting
at all. Please refer to the local regulations for its disposal.
6.2 MACHINE INSTALLATION
The machine has not to be anchored to the floor.
For a correct use and operation, as well as for an easy maintenance, leave enough free space around the
machine.
Do not place the machine in dangerous and/or explosive/inflammable places.
6.3 ELECTRICAL WIRING
The electrical wiring must be carried out as indicated in the drawing. Check that the supply voltage and the
frequency correspond to those indicated on the rating plate. The dimensions of the supply cable must suit the
machine absorption and comply to the current regulations.
It is advisable to install a switch with fuses or a thermal-magnetic circuit breaker on the line.
Put the cable into the cable holder, and then tighten. Connect the cable to the feeder line terminals on the control
panel, as shown on the drawing of the present manual.
Check the rotation direction of the motors; if not correct, invert two of the three input phases with each other.
6.4 STEAM SUPPLY CONNECTION
•Connect the machine to a central steam supply as follows:
Connect a pipe with a G 1/4” gas threading to the top part of the steam outlet of the central unit and place an on-
off-valve close to the machine. Afterwards, connect a pipe with an internal diameter of at least 10 mm to the steam
intake (with G 1/4” threading) of the machine. For the condensation return, provide a pipe with exactly the same
features of the steam pipe, and install an on-off valve followed by a check valve close to the machine. For the
connection to the check valve, use a pipe with an internal diameter of at least 10 mm.
The steam network pressure must be of max. 4.5 bar.
•In case of a connection to a small steam generator, proceed as follows:
The steam intake of the machine features a G 1/4” threading for the connection to the steam generator The steam
network pressure must be of max. 4.5 bar.
It is advisable to install a pipe having an internal Ø of at least 8 mm. Install an on-off valve on the piping in order to
exclude the machine from the steam generator. Connect the condensation return to the machine (with a G 1/4"
threading), by using also in this case a pipe with an internal Ø of at least 8 mm. Install on this piping a check-valve
and an on-off valve, in order to exclude the machine from the installation. Connect eventually to the small steam
generator.
Do not bend the pipes at right angles, but at least with a 50 mm radius. Make sure that the pipes have an even
incline, especially the one for the condensation return.
Do not create traps; don’t use fittings or gate valves with a smaller diameter than the pipe, itself. The piping must
not exceed 2.5 meters. The hole of the condensation return has to be at least 150 mm higher than the water level
inside the boiler.
WARNING: After having carried out all the connections, make sure that pipes and cables are protected against any
possible hits and are suitably fixed and isolated.
7 INSTRUCTIONS FOR USE
7.1 PUTTING INTO OPERATION
•The whole unit can be used, opened and repaired by qualified technicians only.
•It is forbidden to use the machine if flooded by liquids or in particularly aggressive or explosive/inflammable
places.
•Do not ignore the dangers for the operator’s health and follow the hygienic and safety regulations.
•Check that the electrical wiring is carried out correctly according to the current regulations, and that the
fuse blocks are closed and complete of fuses.
•Make sure that the machine is intact.
