5.11 - Electrical connections
ATTENTION !!! The appliance is only electrically
safe when it has been correctly connected to an
efficient earth circuit, performed as envisioned by the
current Safety Standards.
This fundamental safety requirement must be met. If in
doubt, request a thorough control of the electric plant by a
professionally qualified technician.

Have a professionally qualified technician check that the
electric plant is suitable for the electric power required by
the appliance, indicated on the plate.

The appliance must be connected to the mains electricity
using a cable coupler. The use of adapters, multiple
sockets, extensions, etc. is not allowed.

The appliance must be connected to the mains electricity
using a three-polar electric cable, with double isolation,
minimum section of 1,5 mm² and resistant to a minimum
temperature of 70°C (characteristic T).

For connection to mains electricity, a bi-polar switch
must be envisioned in the vicinity of the appliance with a
contacts opening distance of at least 3mm, as envisioned
by the current regulations on the subject.

Respect the polarity between the neutral phase during
connection of the appliance.

Make sure that the water plant pipes are not used as
earth points for the electric or telephone plant. This
piping is not suitable for this purpose, moreover, serious
corrosion damage would occur in a very short time, on
the appliance, piping and radiators.
