UNO / DUO BOOSTER BASIC
Original Instructions
3.3 Wall mounting
3.4 Water connection
UNO BOOSTER:
Only mount the machine on a
solid wall construction suited for
the mounting of a machine. I.e.
a concrete or brick wall.
Do not mount the machine
on a wall where it will cause
disturbances in neighbouring
rooms (canteens, offices etc.).
DUO BOOSTER:
Place the machine on a plane
floor.
Machine feet have been
mounted under the machine.
These must be adjusted so that
the machine stands stable.
The water connection is
made through a flexible hose
connected to the quick coupling
on the water inlet (1) of the
machine.
The connection can be made
to a water supply network or an
internal water supply. A shut-
off cock should be mounted
on the water supply network
in the immediate vicini ty of the
machine.
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 filter (50 micron)
should be mounted beyond the
internal filter of the machine
(for further connection data see
section 8 Technical 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 Nilfisk-
ALTO distributor).
Clean the water inlet filter (1)
once a month.
