• 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 and 60Hz) 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.

10.2 SWITCHING THE PUMP ON AND OFF
• When the pump is first connected to the network, it will
operate with factory settings, i.e. in automatic mode
• At each following start-up, the pump will operate with
the last settings that were set prior to its last shut-down
• To switch the pump off, press and hold the - key for
5 seconds, until OFF is shown on the display. Once the
pump is switched off, the OFF sign will remain visible
on the numerical display
• To turn the pump on, briefly press the - key
