Hydraulic connection
5.7.1 Water supply
The water supply of the appliance must be carried
out with water which is suitable for human consump-
tion, in compliance with the regulations in force in the
place of installation. The owner/manager of the system
must confirm to the installer that the water meets the
requirements above:
5.7.2 Materials to be used
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.
5.7.3 Hydraulic connections
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.
1. Add a tap to the water supply so as to stop water
from flowing to the machine;
2. in order to prevent damage, it is advisable to install
the water purification filter where it will be pro-
tected from accidental blows;
3. if there is no water purification filter (
9
), connect
the water supply (
11
) directly to the inlet of the
machine (
6
);
4. when connecting the pad of the machine (
5
) to the
sewer drain (
4
), avoid overly tight curves or kinks,
and make sure that there is sufficient inclination for
water to flow out of the drain;
5. the drain must be connected to an inspectable
siphon that can be periodically cleaned, in order
to avoid bad odors;
6. to avoid oxidization and damage to the machine
over time, do not use iron connections for the hy-
draulic system, even if galvanized.
