Hydraulic connection

6.7
6.7.1 Water supply
The appliance's water supply must provide water
which is suitable for human consumption, and must
conform with the regulations in force in the place of
installation. The owner/ manager of the system must
give confirmation to the installer that the water meets
the above requirements:
6.7.2 Materials to be used
When installing 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 if they are suitable for coming into
contact with water used for human consumption.
6.7.3 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 in order 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) and/or
motor pump (13), connect the water mains (11)
directly to the machine's water inlet (6);
4. When connecting the machine's tray (5) to the
sewer drain (4), avoid overly tight curves or kinks,
and make sure that there is sufficient inclination for
water to flow to the drain;
5. The drain must be connected to a siphon that can
be inspected and periodically cleaned, in order to
prevent unpleasant odours from returning;
6. To avoid oxidisation building up and damage to the
machine over time, do not use iron connections for
the hydraulic system, even if they are galvanised.
