3.4. Water connection
Inlet and outlet water connections should comply
with applicable laws in force in the country where
the machine is used.
- connect the water mains (
2
) to the inlet on the back
of the machine (
6
) using the hose provided. Then
open the tap of the water mains.
- connect the drain tub of the machine (
4
) to the sewer
drain (
3
) using the special tube provided. Take care to
avoid overly tight bends or kinks, and make sure that
there is sufficient inclination for water to flow out of
the drain..
Warning
Check that the surface prepared for the machine
installation, has dimensions and sturdiness suitable
to safely support the machine.
Note
For a correct ergonomic use of the machine, place
it on a working surface not lower than one meter
from the floor.
Warning
For correct operation, the machine must rest on a
perfectly horizontal surface. Any alignment adju-
stments of the machine must be done by adjusting
the feet.
Note
All filling connections are 3/8 male gas type. The
drain tub is connected with a tube with an internal
diameter of 16mm.
Warning
Insert a tap (8) and a non-return valve (9)on the
water mains supply so that it will be possible to cut
off water flow to the machine.
Connect the water mains (2) directly to the inlet of
the machine (6). If you decide to install a water sof-
tener (11), connect the water mains (2) to the inlet
of the water softener, and the outlet of the water
softener to the inlet of the machine (6).
To prevent the water from freezing, install the sof-
tener (11), only in rooms with an ambient tempera-
ture of more than 5°C.
When connecting the tub 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.
The drain must be connected to an inspectionable
siphon that can be periodically cleaned in order to
avoid the backflow of unpleasant odours.
To avoid oxidization and damage to the machine
over time, do not use iron connections for the
hydraulic connections, even if they are galvanized.
Attention
The hydraulic connection must be made in com-
pliance with local national standards.
If an external tank is used, the connection pipe
between the machine and the tank must not
exceed 150 cm.
For the European Community: for both the
hydraulic connection to the water mains as well
as the connection to an external tank, a non-
return valve (9) must be placed up the line from
the machine as set forth by standards EN 1717.
Warning
The water mains must provide cold water for
human consumption (potable water) at a maximum
pressure of 5 bar inclusive If the pressure is greater
than 5 bar, connect a pressure reducer upstream
from the pump.
