TECHNICIANS manual
ENGLISH
The water supply must provide cold water 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 lling connections are 3/8 male gas type. The drain pan is
connected to a tube 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 equipped with a time-limit switch that allows
the water to ll the boiler only for a limited time. This function
keeps water from owing out of the boiler's valve (ooding) and
keeps the motor pump from overheating.
FOR THE EUROPEAN COMMUNITY: for the hydraulic connection to
the water mains and also for connection to an external tank, it
is necessary to place a non-return valve (12) up the line from the
machine as set forth by standards EN 1717.
FOR THE U.S.A. - The water connections and discharges must
be made in accordance with the 2003 International Plumbing
Code of the International Code Council (ICC), or with the 2003
Uniformed Hydraulic Code of the IAPMO. The machine must be
installed together with an adequate non-return valve, as required
by national regulations.

5.8 Electrical connection
• Installation must be done in accordance with the
safety standards in force in the country of installation.
The owner/manager of the system must conrm to
the installer that the electrical system meets the re-
quirements above.
• Install a general protection switch (8)
as required by current safety regula-
tions suitable to the rated power.
• For the electrical connection of the
machine, refer to Chap. 16 on page 64 .
• Do not use power extensions or electrical adaptors for
multiple outlets. If their use is absolutely necessary,
use only simple adapters and extensions complying
with current safety standards. Never exceed the ca-
pacity value indicated on the adapter and the exten-
sion cord, and that 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 be able to leave
the area immediately in case of necessity.
We recommend to promptly report to the Manufacturer any
problems encountered during installation of the equipment.
