The water supply must provide cold water fit for human
consumption (potable water) at a pressure between 1.5 and 5 bars.
If the pressure is higher than 5 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
machine 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 heating unit's
valve (flooding) and keeps the motor pump from overheatinga.
FOR THE EUROPEAN COMMUNITY: when connecting to a water mains
or an external tank, a non-return valve (12) must be positioned
upstream from the machine, as set forth by the EN 1717 standard.
FOR THE USA - The water connections and drains must be made
in accordance with the 2003 International Plumbing Code of the
International Code Council (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.

Electrical connection
•
Installation must be carried out in accordance with
the safety standards in force in the country of instal-
lation. The owner/ manager of the system must give
confirmation to the installer that the electrical system
meets the above requirements.
•
Install a main safety switch
(8)
as set
forth by the current safety regulations
regarding rated power.
•
To connect the machine to the elec-
tricity distribution system, refer to chap. 13.
•
Do not use power extensions or electrical adaptors
for multiple outlets. If their use is absolutely neces-
sary, use only simple adapters and extensions which
comply with current safety standards. Never exceed
the capacity indicated on the simple adaptor or ex-
tensions, and the maximum power indicated on the
adaptor.
•
The access spaces to the machine and main switch
must be left clear, in order to allow the user to inter-
vene without any constrictions and leave the area
immediately when needed.
We recommend that you promptly report any problems encountered
during the appliance’s installation to the Manufacturer.
For single-phase connection - In compliance with EN 61000-3-11,
the equipment must be connected only to a power supply network
with an impedance equal to or less than - Zmax single-phase:
0.239 Ohm.
For Australia - When connecting the appliance to the mains,
a device must be provided for which ensures an omnipolar
disconnection from the mains with a contact opening distance in
the conditions of overvoltage category III and in accordance with
the AS/NZS 3000 regulations.
