7. INSTALLATION, DISMANTLING
AND TRANSPORT
7.1 GENERAL ARRANGEMENT FOR INSTALLATION
• The pump must be mounted with electromotor shaft
in horizontal position (fig. 3.1). Allowed and forbidden
positions are shown in fig. 3.2
• The arrow on pump plate shows direction of medium
flow
• If there is not enough space for electric connection,
control box can be rotated so that the connector is in
a horizontal position
• A position with the electrical connector vertically above
the motor is not allowed (see fig 3.3c)

• Prior to rotating the electric motor part, close the shut-off
valves on the pressure and suction side of the pump and
unscrew the screws (Fig. 3.3). Turn the electric motor
part as shown in Fig. 3.3a or 3.3b.
7.2 DISMANTLING
In order to handle and dismantle the electropump you should:
a) Take off the power supply.
b) Lift the electropump with suitable means according to
its weight and dimensions
7.4. TRANSPORT
The electropump is packed in a carton or, depending on
its weight and dimensions, it is fixed on a wooden pallet;
however, transport does not present many difficulties.
In any case, check the total weight imprinted on the box.
8. ELECTRICAL CONNECTION
8.1. PROTECTIVE DEVICES
• ALL THE CONNECTIONS MUST BE EXECUTED
ACCORDING TO THE LAW BY A QUALIFIED TECHNICIAN.
• ALL THE ELECTRICAL MASSES MUST BE CONNECTED
TO THE EARTH OF THE PLANT ACCORDING TO
THE ELECTRICAL STANDARDS IN FORCE IN YOUR
COUNTRY: THE INSTALLER SHALL BE THE SOLE
RESPONSIBLE FOR IT.
• FOR THE THREE-PHASE AND SINGLE-PHASE TYPES,
WE RECOMMEND INSTALLING A HIGH SENSITIVE
DIFFERENTIAL SWITCH (0.03 A).
After installing the unit check again the feeding cable
following the CABLE CONNECTION instructions and
connect it to the control panel that must be fitted, according
to the actual rules, with:
