POTENTIAL-EQUALIZING CONNECTION
This connection, which is the one called
for by several norms, avoids electrical potential
differences, building up between any equipment that
may be installed in the same room. There is a terminal
clip on the under side of the base of the machine to
which an external potential-equalizing wire should
be connected.
This connection is absolutely necessary and must be
made right after the machine is installed.
Use a wire whose cross-sectional area conforms to
the existing norms.
6.3. Antisuction valve installation (Fig.7)
On the top of the boiler there is the antisuc-
tion valve.
When installing the machine be sure to remove
the plastic fork "A" and check that the pin "B" is
not blocked.
This operation is very important for the correct
working of the machine.

6.4. Positioning

●Place the machine on the horizontal sur-
face previously prepared.
Before connecting, thoroughly wash the mains water
pipes:
● Leave the water supply taps running at full pres-
sure for several minutes.
● Connect to the mains water supply.
● Connect the machine to the socket.
● Connect the gas pipe
Thoroughly wash all the water pipes of the machine:
● Leave the water supply taps running at full pres-
sure.
● Switch on main switch (pos.1 - Fig.8): wait until the
boiler fills up to the level set.
● Switch on main switch (pos.2 - Fig.8) to begin
heating the water in the boiler.
● Operate each unit in order to allow the water to
escape for about one minute; repeat the operation
twice.
● Deliver steam from the steam jets for about one
minute.
● Deliver hot water for about one minute; repeat the
operation twice.
● Switch off switches 1 and 2.
● Empty the water from the boiler: see point 10.3
IMPORTANT
Should the machine not deliver water for over
24 hours, wash the internal components be-
fore beginning work, repeating the operations
as described above
