3.6 Water connection
that the water supply is within
the following specifi cations and
that the water does not contain
particles such as fl oating sand.
Min. water inlet pressure: 1 bar
(at the required fl ow rate of the
machine - see data plate.
Max. water pressure: 10 bar
Max. water inlet temp. (EH/GH):
85°C.
Max. water inlet temp. (D/G):
30°C.
All SOLAR BOOSTER feature
a water tank, and no further
protection against back-fl owing
water into the supply network is
required. The machine complies
with EN 1717.
If there is a risk of fl oating sand
or other impurities in the inlet
water, a sand fi lter (50 micron)
should be mounted between the
supply outlet and the internal
fi lter of the machine.
Clean the water inlet fi lter (7)
once a month or in case of
poor throughput (inlet pressu-
re below 1 bar at the fl ow rate
required by the machine).

The water connection is made
through a fl exible hose connect-
ed to the quick cou pling on the
water inlet (7) of the machine.
Make sure that the supply
hose is suited for the purpose
(temperature and fl ow rate). If
in doubt, contact your Nilfi sk-
ALTO representative.
The connection can be made to
a public drinking water supply
network or a private water sup-
ply. A shut-off cock should be
mounted on the water supply
network in the immediate vicini-
ty of the ma chine. Make sure
