system must be "OPEN, WITH NO
TRAP" and the material for pipe fit-
ting and containment must support
high temperatures of approximately
70°C in the appliance outlet area.
To perform a correct disposal of the
•
waters in the drainage system, make
sure there are no obstructions and
no type of hindrances on the whole
line length.
Check the correct inclination of the
•
device for grey water containment
and downflow. The device must let
the grey water easily drain away into
the system drain.
Increase the angle of incidence
(from 3° to 5° approximately) of
the drain into the system whene-
ver any backwater occurs.)
Connect an edge of the drain pipe to
•
the appliance connection;
Convey the opposite edge of the pipe
•
to the open drain (with no trap).
Make a visual check of the connection
•
seal and of the drain water downflow.
See schematic drawing (Fig. 5).
ELECTRICAL CONNECTION
Electrical connection should be per-
formed in compliance with the local
regulations in force, only by authorised
and competent personnel. In the first in-
stance, examine the data shown on the
technical data table of this manual, on the
serial plate and on the electrical diagram.
Connect the equipment to an
overvoltage category III omnipo-
lar device.
EARTHING / It is essential to
earth the unit.To this purpose, it
is necessary to connect to an ef-
ficient earthing system the terminals
marked with the symbols placed on
the line-receiving terminal box. The
earthing system should comply with
the local law in force.
THE PRESENT MANUAL IS PROPERTY OF THE MANUFACTURER. ANY REPRODUCTION, EVEN PARTIAL, IS PROHIBITED.
POWER SUPPLY CONNECTIONS
SPECIFIC WARNINGS / The electrical
safety of this unit is assured only when
it is correctly connected to an efficient
earthing system as stated in the electri-
cal local safety regulations in force; the
Manufacturer declines any responsibi-
lity for the non-compliance with these
safety regulations.It is necessary to
verify this fundamental safety requisite
and, in case of doubt, ask for an accu-
rate testing of the system by professio-
nally qualifi ed personnel.
The Manufacturer cannot be deemed
responsible for any damages caused
by the lack of unit earthing.
Never interrupt the earth wire
(Yellow-Green).
CONNECTION TO THE DIFFE-
RENT
TION NETWORKS / see SECT.
IMAGES - REF. e) / The equipment
is delivered to work with the voltage
indicated on the technical label at-
tached on the appliance. Any other
connection is to be considered im-
proper and therefore dangerous.
It is mandatory to respect the
connection provided by the
manufacturer, visible on the con-
nection label near the terminal board.
It is forbidden to modify the
wiring inside the equipment
ELECTRICAL CONNECTION
OF THE CABLE TO
THE TERMINAL BOARD /
Connect the power cable to the termi-
nal board as described in: "Power sup-
ply connection" and indicated on the
connection plate.. The diagram and the
table (see Technical data) indicate the
possible connections according to the
mains voltage.
