Connecting To The Water Supply; Connecting To The Drainage System - Smeg SPO5 Series Manual

the water supply pipes.
• The appliance is fitted with a suitable
"John Guest" hose (¾ female fitting)
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 be-
tween 200 kPa - 1000 kPa (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.

6.4 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 connect-
ed to high temperature 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
elbow joints (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.
