6.1. Connections to be made by the
user
Hook-up must be carried out by qualified
personnel in full accordance with federal,
state and local regulations.
6.1.1. Water and gas supply (Fig.5)
This equipment is to be installed to
comply with the applicable federal, state
or local plumbing codes.
Connections must be installed close to the machine.
● Water drainage pipe 1, having a minimum internal
diameter of 30 mm, equipped with a water-trap
accessible for inspection.
● Water supply pipe 2, with a 3/8"G cut-off tap.
● Gas supply pipe 3, with a cutoff tap.
Make sure that the maximum supply pressure
does not exceed 6.5 bar; otherwise, install a
pressure reducer.
The machine with gas heating must be instal-
led in compliance with current local laws.
6.1.2. Electric supply
The machine is supplied ready for connection
according to the required electrical specifications.
Before connecting the machine ensure that the plate
details comply with those of the electric distribution
network.
The electrical connection cable must be directly
connected to the connection provided according to
current legislation. Ensure that the earthing system
is efficient and in compliance with current legal re-
quirements.
The earthing system and the lightening protection
system must be realized in accordance with the
provisions of current legislation.
For the supply network use a cable in compliance with
standards with protective conductor (earthing wire).
For three-phase power use a cable with 3 conductors
( 3 phases + neutral + earth).
For single phase power supply use a cable with 3
conductors (phase + neutral + earth).
In both cases it is necessary to provide an automatic
differential switch (Fig.5) at the start of the power cable,
complete with magnetic release elements in accord-
ance with the identification plate details (Fig. 1). The
contacts must have an opening of equal or over 3 mm
and with dispersed current protection of 30 mA.
Remember that each machine must be fitted with its
own safety elements.
WARNING:
Should the power supply cable be damaged
it is to be replaced by the manufacturer or by
its technical assistance service or by person
with equivalent qualification, in order to pre-
vent any risks.
6.2. Preliminary operations (Fig.6)

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.
6.4. Connections
● Place the machine on the horizontal
surface 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 1 (Fig.8): wait until the boiler
fills up to the level set.
● Switch on boiler resistance switch 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
10.3.1.
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.
6.3. Lever assembly (Mod.L) (Fig.7)
During the installation, the lever shall be assem-
bled.
To carry out this operation, assemble the upper case
according to the instructions in Fig.7 (1 and 2).
Fix the case by tightening the screws and then screw
the lever in the upper part.
