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 Figure 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 (Figure 3.3). Turn the electric
motor part as shown in Figures 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 (1) that must be fitted,
according to the actual rules, with:
• An omnipolar device for switching-off/separation of
the net (minimum opening contacts 3 mm).
• A protection against short circuits (Am fuse) and
magnetothermics, rated in compliance with the
current plate.
• Possible devices against: lack of phases, electric
dissipations, lack of water, atmospheric discharges
and functioning-failure indicators.
IMPORTANT: ALL THE ELECTRIC MASSES MUST
BE CONNECTED TO THE EARTH OF THE PLANT.
8.2. CABLE CONNECTION
• Connection to the mains is carried out with the enclosed
connector. Its mounting instructions are shown in the
picture accompanying the connector.
• The electrical connection of the pump to the mains (230V,
50 Hz) must be carried out with suitable standardised
connecting cord
• When connecting the mains cable ensure it never comes
in contact with the casing of the device, due to the high
temperatures of the casing.
9. USE AND RUNNING
• • Before the startup, it is necessary to fill the pump
with fluid and to vent the system
• Pumps Ego do not need to be manually vented, as
this occurs automatically when the hydraulic system
is being ventilated during the start-up. The air in the
pump generates noise. After a short working period
noise should disappear.
• For a proper functioning, a minimum pressure at suction
must be guaranteed (see LIMIT OF USE)
During its running, it is normal for the pump to
heat up, or to be heated by the pumped fluid - to
prevent from risk of burns, it should therefore
not be touched!
• The pump's openings and electric motor housing (Figure
3.1, detail A) between the hydraulic housing and the
electric motor housing should not be insulated, since
the thermal insulation might hinder cooling and drainage
of condensate from the pump's motor housing.
