3.4 Water connection
The connection can be made
to a water supply network or an
internal water sup ply. A shut-
off cock should be mounted
on the water supply network
in the immediate vicini ty of the
ma chine.
Max. water pressure: 10 bar
Max. water inlet temp.: 70°C
The machine features a water
tank, and no further protection
against return water into the
supply network is required. The
machine complies with EN 1717.
If there is a risk of running sands
or other impurities in the inlet
water, a sand fi lter (50 micron)
should be mounted beyond the
internal fi lter of the machine
(for further connection data see
section 8 Tech ni cal data).
If mounting the by-pass hose,
the water inlet temperature can
be raised to 80°C. ONLY do
this if there is a separate water
supply (contact your Nilfi sk-
ALTO distributor).
Clean the water inlet fi lter (1)
once a month.
