Connecting To The Drainage System - Smeg SPO5L2S Manual

with relative seal and mechanical filter
on one side. On the other side, it is pos-
sible to connect the hose via an 8mm
quick hose coupling.
• The appliance is connected to the wa-
ter supply via the quick coupling at the
bottom of the back of the appliance.
• Only use new hoses when connecting
to the water supply. Old hoses should
not be reused.
• The water supply pressure should be
between 200kPa - 1000kPa (2-10 bar),
the ideal pressure for correct washing is
3 bar. Lower pressures can affect both
the washing and steam cooking results.
SUPPLEMENTARY NOTE: before
connecting the product to the water supply,
make sure that the water system has been
fitted with a safety device to protect drink-
ing water against contamination due to
backflow (according to DIN EN 1717). The
water valves and/or taps will already be
fitted with these safety devices if the water
system has been properly implemented.

7.4 CONNECTING TO THE
DRAINAGE SYSTEM
• The connection to the waste water
drainage system must be compliant with
current regulations.
• The appliance should be connected to the
waste water drainage system via the pipe
at the lower back of the appliance. The
pipe should be connected to high temper-
ature resistant pipes (90°C-100°C) that
have an external diameter of 40 mm (DN
40). Do not use metal pipes.
• The drainage pipes should be rigid and
must not be pinched. The pipe must have
a minimum slope of 4% – 5% along its
entire length.
• The length of the pipes between the
appliance and the discharge should not
be longer than 2 metres. Limit the use of
sharp bends (90°).
• A water trap (not supplied) should be
provided between the appliance and
the drain to prevent the return of va-
pours and odours. The water trap and
drainage pipes should be checked and
cleaned periodically (see figure below).
• If there are other appliances connected
to the same drainage pipe, make sure it
is large enough allow proper drainage
and unobstructed flow.
