• The electrical connection is made in a dry place, far from any
possible flooding.
• The electrical system is provvided with a differential switch
with I Δn ≤ 30 mA and that the earth system is efficient.
If you are not sure of the absence of foreign bodies in the water to be
pumped, install a filter on the system intake that is suitable for catching
impurities.
The installation of a filter on intake causes a decrease of the
system's hydraulic performance proportional to the loss of load
caused by the filter itself (generally the greater the filtering power,
the greater the fall in performance).
Choose the type of configuration you intend to use (vertical or horizontal)
considering the connections to the system, the position of the user inter-
face panel, and the spaces available according to the indications below.
Wall installation is possible, see par. 8.2.
2.1 - Vertical Configuration
Screw the 4 rubber feet supplied loose in the package into the brass seats
in face C. Put the system in place, taking into account the dimensions in
Fig.7.

• The distance of at least 10mm between Face E of the system and any
wall is obligatory to ensure ventilation through the grids provided • I f
you expect to have to drain the system from its discharge door and
not from the system, leave a further distance sufficient to manoeuvre
the drainage cap.
• The distance of at least 10mm between Face B of the system and
an obstruction is obligatory to let out the power supply cable to the
mains socket.
• The distance of at least 200mm between Face A of the system and an
obstruction is recommended so as to be able to remove the door and
gain access to the technical compartment.
If the surface is not flat, unscrew the foot that is not touching and adjust
its height until it contacts the surface so as to ensure the stability of the
system. The system must in fact be placed in a safe and stable position,
ensuring that its axis is vertical: it must not be in an inclined position.
2.1.1 Hydraulic connections
Make the connection at input to the system through the mouth on Face F
marked "IN" in Fig.7 (suction connection). Then remove the cap using a
screwdriver. Make the connection at output from the system through the
mouth on Face F marked "OUT" in Fig.7 (delivery connection). Then re-
move the cap using a screwdriver.
All the hydraulic connections of the system to the plant to which it can be
connected are of the threaded female type 1" GAS, made of brass.
If you intend to connect the product to the plant with fittings that
have a diameter larger than the normal 1" pipe (for example the
ring nut in the case of fittings in 3 pieces), make sure that the 1"
Gas male thread of the coupling protrudes at least 25mm from
the above diameter (see Fig.8).
