Hydraulic connection

Remove any rubber plugs which may be inserted in
the tap fixtures of the softener;
connect the water supply (12) to the softener inlet
(10) using the provided flexible hose;
rinse the resins from the softener and check that the
water, which initially comes out yellowish, comes
out clean;
connect the softener outlet (11) to the external motor
pump inlet (13);
connect the outlet of the motor pump (14) to the inlet
of the machine (7);
connect the drain pad of the machine (6) to the sewer
discharge (5) using the special hose provided, avoid-
ing overly tight bends or kinks, and making sure that
there is sufficient inclination for water to drain.
!
All filling connections are 3/8 male gas type. The
drain pan is connected to a tube with an internal
diameter of 16mm.
The water supply of the appliance must be carried
out with water which is suitable for human
!
consumption, in compliance with the regulations in
force in the place of installation. The installer must
receive, from the owner/manager of the system,
confirmation that the water meets the above listed
requirements.
During the installation of the appliance, only the
components and materials supplied with the
appliance are to be used. Should the use of other
components be necessary, the installer must verify
!
their suitability to be used in contact with water
used for human consumption. The installer must
carry out the hydraulic connections in accordance
with the hygiene norms and the hydraulic safety
norms for environmental protection in force in the
place of installation.
Warnings
1.
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.
Technical manual
2.
add a tap (15) to the water supply so as to stop water
from flowing to the machine;
3.
in order to prevent damage, it is advisable to install
the softener where it will be protected from accidental
blows;
4.
to prevent water from freezing, install the softener
inside a premise with a room temperature higher
than 5°C;
5.
if there is no softener, connect the water supply (12)
directly to the inlet of the external motor pump (13);
6.
if there is an internal motor pump, connect the outlet
of the softener (11) (if there is one) or the water supply
(12) directly to the machine inlet (7);
7.
when connecting the pad of 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.
8.
the drain must be connected to an inspectable siphon
that can be periodically cleaned, in order to avoid
bad odours;
9.
to avoid oxidization and damage to the machine over
time, do not use iron connections for the hydraulic
system, even if galvanized.
The hydraulic connection must be made in
compliance with local national standards. In case
of use of an external tank: the connection hose
!
between the machine and the tank can't be longer
than 150 cm. For the European Community: both
for the hydraulic connection to the water supply,
and for the connection to an external tank, it is
necessary to place a non-return valve (16) on the
machine as set forth by EN 1717 standards.
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.
All of the machines are equipped with a "Time-out"
device that allows filling of water in the boiler
within a maximum time. This function keeps water
!
from flowing out of the boiler's valve (flooding)
and keeps the motor pump from overheating. If
the time limit is not enough for the boiler to fill up
completely (such as for the machines installed with
3 or 4 groups), turn the machine off and then back
on, and repeat the operations listed above.
