3.4 Water connection
3.5 Mains power connection
Original Instructions
The water connection is made
with a fl exible hose connected
to the water tank (7) of the
machine.
The water hose can be lead in
through:
1. The bottom plate
2. The punch-out pieces in the
rear plate
(see illustration at the end of
this manual).
Make sure that the supply
hose is suited for the purpose
(temperature and fl ow rate). If
in doubt, contact your Nilfi sk
representative. Also ensure that
the water supply hose is pro-
tected against freezing between
the outlet and the SH AUTO.
CAUTION! An
authorized electri-
cian must perform
the electrical
connection of the machine to
the main power supply. Refer to
section "1 Safety precautions
and warnings".
The connection can be made to
a public drinking water supply
network or a private water sup-
ply. Water quality: particle size
<50 . A shut-off cock should
be mounted on the water sup-
ply network in the immediate
vicinity of the machine. Make
sure that the water supply is
within the following specifi ca-
tions 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.: 30°C.
All SH AUTO feature a water
break tank, and no further
protection against back-fl owing
water into the supply network is
required. The machine complies
with EN 60335-2-79.
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.
Do not forget installation of
HPFI type B.
The following precautions must
be observed:
Make sure that the supply
cable is of the correct di-
mension (see voltage and
load on the data plate of the
machine (15)) and that it is
suitable for the specifi c envi-
ronment.
