
Do not subject the motor to excessive starts/hour; it is strongly recommended not to exceed 20 starts/hour.
The diameter of the suction pipe must be greater than or the same as the diameter of the pump inlet,
see Table 2.

7. ELECTRICAL CONNECTION

Ensure that the mains voltage is the same as the value shown on the motor plate and that there is the
possibility of making a good earth connection.
manual, table 2. The length of the power cable on the pump limits the installation distance, if an
extension is required, make sure that it is of the same type (e.g. SJTOW 16AWG o SJTW 15AWG
depending on the installation) see tab 2.

8. START-UP

Do not start the pump without having completely filled it with liquid, about 4 litres.
If the water supply is finished, take the plug out of the socket immediately and switch off the pump. Avoid dry running.
1.
Before starting, check that the pump is properly primed, filling it completely, with clean water, through the filling
hole, after having removed the filling cap of the transparent filter (1), with your hands or with the appropriate tool
provided. This ensures that the mechanical seal is well lubricated and that the pump immediately starts to work
regularly. Dry operation causes irreparable damage to the mechanical seal.
2.
The filling cap must be screwed on accurately until it stops (1).
3.
Insert the plug of the power cable in a 115-120V power socket. Attention! The pump motor will start immediately,
the water will start to come out after a maximum time of 3 minutes, depending on the depth of the water level, in
the well or cistern.
4. The pump is automatically deactivated when the maximum pressure is reached. If, when using water, the pressure
falls below the minimum value, the pump is activated automatically. See Tab.2.
5.
To switch off the pump completely, take the plug out of the power socket.
In case of problems with the priming, repeat the handling until all air in the suction is disappeared.

9. PRECAUTIONS

RISK OF FROST: when the pump remains inactive at a temperature lower than 32 F, it is necessary to ensure that there
is no water residue which could freeze, causing cracks in the plastic parts.
If the pump has been used with substances that tend to form a deposit, or with water containing chlorine, rinse it after use
with a powerful jet of water in order to avoid the formation of deposits or encrustations which would reduce the
characteristics of the pump.

10. MAINTENANCE AND CLEANING

In normal operation the pump does not require any type of maintenance. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains. When restarting the pump, ensure
that it has been correctly reassembled, so as not to create a risk for persons and property.

11. TROUBLESHOOTING

Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove
the plug from the socket). If there is any damage to the power cable or pump, any necessary repairs
or replacements must be performed by the manufacturer or his authorized customer support
service, or by an equally-qualified party, in order to prevent all risks.
