The water mains must supply cold water fit for hu-
man consumption (potable water) at a pressure be-
tween 0.15-0.6 Mpa (1.5 and 6 bar). If the pressure is
higher than 0.6 MPa (6 bar), connect a pressure reducer before
the pump.
All the filling couplings are 3/8 male gas types.
The drain tray is connected to a pipe with an internal diameter
of 20 mm.
If an external tank is used, the connection pipe between the ma-
chine and the tank must not exceed 150 cm.
The machines are fitted with a "Timeout" device which allows
the heating unit to be filled up with water within a maximum
time. This function prevents water from flowing out of the heat-
ing unit's valve (flooding) and keeps the motor pump from over-
heating.
FOR THE EUROPEAN COMMUNITY: when connecting
to a water mains or an external tank, a non-return
valve (50) must be positioned upstream from the ma-
chine, as set forth by the EN 1717 standard.
FOR THE USA - The water connections and drains
must be made in accordance with the 2003 Interna-
tional Plumbing Code of the International Code Coun-
cil (ICC), or the 2003 Uniformed Hydraulic Code of the IAPMO.
The machine must be installed with a suitable non-return valve
as set forth by the national standards.
5.7.4 Electrical connection
• The conformity of the electrical system, eectiveness of
the earthing system and functionality of the dierential
circuit breaker - all of which are fundamental for guaran-
teeing the appliance’s electrical safety - are the responsi-
bility of the person in charge of the electrical system on
which the equipment is installed.
• Before installation, make sure that the
electrical system is equipped with the
protection device (46), as indicated in the
safety notes on page 28.
• To connect the machine to the electric mains, refer to Chap.
"12. WIRING DIAGRAMS" on page 43.
• Do not use extension leads or electrical adapters for mul-
tiple outlets.
• The access spaces to the machine and main switch must
be left clear, in order to allow the user to intervene with-
out any constrictions and leave the area immediately when
needed.
If an external motor pump is being used, proceed as follows:
• Connect the motor pump cable (with the smaller cross-
section) to the connector of the external motor as shown
in the diagram below.
• Connect the machine power cable (with the larger cross-
section) as indicated in Chap. "12. WIRING DIAGRAMS" on
page 43.

5.7 Hydraulic connection
Before connecting the hydraulic system, make sure
the appliance has been disconnected from the elec-
trical mains.
5.7.1 Water supply
The appliance’s water supply must provide water which is
suitable for human consumption, and must conform with the
regulations in force in the place of installation. The owner/
manager of the system must provide the Technician with con-
firmation that the water meets the above requirements.
5.7.2 Materials to be used
When installing the appliance, only the components and ma-
terials supplied with the appliance are to be used. Should the
use of other components be necessary, the Technician must
verify that these are suitable for coming into contact with wa-
ter used for human consumption.
5.7.3 Hydraulic connections
The Technician must carry out the hydraulic connections in
accordance with the hygiene and hydraulic safety standards
regarding environmental protection which are in force in the
place of installation.
• Add a valve to the water supply (51) in order to stop water
flowing to the machine.
• In order to prevent damage, it is advisable to install the
water purification filter where it will be protected from ac-
cidental blows;
• If there is no water purification filter, connect the water
mains (50) directly to the machine's water inlet (44).
• When connecting the machine's tray (43) to the sewer drain
(49), avoid overly tight curves or kinks, and make sure that
there is a sucient slope for water to flow to the drain;
• The drain must be connected to a siphon that can be in-
spected and periodically cleaned, in order to prevent un-
pleasant odours returning.
• To avoid oxidisation building up and damage to the ma-
chine over time, do not use iron connections for the hy-
draulic system, even if they are galvanised.
After installation and before using the machine, the
water in the hydraulic circuits must be replaced, as in-
dicated in para. "6.7 Water renewal" on page 28.
New connecting pipes must be used every time that
the machine is newly installed. Do not use old con-
necting pipes.
