TECHNICIANS manual
ENGLISH
•
connect a pipe to the outlet of the Y-connector to
drain the sewage system
•
connect the water supply hose to the water filter
and, in turn, to the hydraulic network
•
connect the machine's power cable, as indicated
in para. 6.8
•
when connecting the machine to the sewer drain,
avoid overly tight curves or kinks, and make sure
that there is sufficient inclination for water to flow
out of the drain
•
the drain must be connected to a siphon that can
be inspected and periodically cleaned, in order to
prevent unpleasant odours from returning.

After installation and before using the machine, the water in the
hydraulic circuits must be replaced, as indicated in para. 7.7, on
page 29.
For every new installation, to use new pipes of connection. Don't
use the old pipes of connection.
The water mains must provide cold water fit for human
consumption (potable water) at a pressure between 0.15 and 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
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 overheating.
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
•
The installation must be carried out in accordance
with the safety standards in force in the country of
installation. 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 electricity distribution
system, refer to Chap. 16 on page 73.
•
Do not use power extensions or electrical adapters
for multiple outlets. If their use is absolutely neces-
sary, only use simple adapters and extensions which
comply with current safety standards. Never exceed
the capacity indicated on the simple adapter or ex-
tensions, and the maximum power indicated on the
adapter.
•
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.
The electric system must be equipped with a suitable 30 mA
residual-current device (RCD).
We recommend that you promptly report any problems encountered
during the appliance’s installation to the Manufacturer.
