conditions other than those stated in the name plate data.
Appliance is not to be used by children or
persons with reduced physical, sensory or
mental capabilities, or lack of experience and
knownledge, unless they have been given
supervision or instruction.
Children being supervised not to play with
appliance.
1. PRELIMINARY INSPECTION
1.1
Delivery and Packing
Submerged electrical pumps are supplied in their original
packing, in which they must remain until installation.
Remove the electrical pump from its packing and verify
its integrity. Also verify that the data on the name plate
corresponds to that desired. Immediately contact the
supplier if there are any anomalies, indicating the nature
of the defect.
If you are unsure about the safety of the electric
pump, do not use it.

2. APPLICATIONS
These submerged electrical pumps are designed for
a wide range of applications, such as water supply to
private homes, for irrigating small areas and for pressure
boosting. They are indispensable in the case of lowering
of the water table and to increase pressure.
Do not use the electrical pump in swimming
pools, garden ponds and similar places where
and when people are in the water.
2.1
Liquids Pumped
Clean, non-aggressive liquids compatible with the
materials used to construct the pump, without solid
particles or bres.
Any sand in the water must not exceed 50 g/m³. A higher
concentration of sand will reduce the life of the electrical
pump and increase the risk of its locking up.
3. PREPARATION / INSTALLATION
3.1
Conditions of Use
The electrical pump is suitable for both vertical and
horizontal installation and must be used with respect for
the following conditions:
• Maximum operating pressure: 10 bar.
• Maximum temperature of the liquid: +40°C.
• Maximum density of the liquid pumped: 1.1 kg/dm³.

• Voltage variation allowed: ±5% (single-phase voltage
220-240V 50Hz – 220-230V 60Hz, 3-phase 380-415V
50Hz – 220-230 / 380-400V 60Hz).
• Protection degree: IP 68.
• Maximum immersion depth: 20 m.
• Maximum diameter of the sucked solid bodies: 2 mm.
3.2
Diameter of the electrical pump
The maximum diameter of the electrical pump is 134 mm.
Verify that the well does not offer restrictions or obstacles
to the descent of the electrical pump.
4. ELECTRICAL CONNECTIONS
Before beginning to work on the electrical pump,
make sure that you have disconnected the
electricity from the power supply mains and that
it cannot be accidentally reconnected.
4.1
General Information
Connections must only be performed by an authorized
electrician in compliance with law in force.
Verify that the data on the name plate match the nominal
values for the power line. Make the connection after
verifying the existence of a working grounding circuit.
It is the installer's responsibility to perform the
connection in compliance with regulations in
force in the country of installation.
The single-phase versions are equipped with internal
variable capacitor according to the power. Otherwise, for
the connection of the capacitor, refer to the information
given here below and to the rating plate of the pump.

For all single-phase versions, motor is protected against
overloads by a thermal device (motor safety device)
inserted in the winding.
For the connection of the three-phase versions refer to
the instructions here below.

time calibrated to:
• Less than 10 seconds with 5 times I
• Less than 10 minutes with 1.5 times I
