Installing the motor in a well or tank
Follow the instructions in the pump or electric pump manual.
When installing the electric pump vertically, make sure the motor does not rest on the bottom of the well or tank.
When installing the electric pump horizontally, make sure the motor does not rest on the bottom of the tank.
For further information, please contact our Sales and Service Department.

Start-up
Follow the instructions in the pump or electric pump manual.
6.1
Electrical connections to the electric pump
Electrical connections may only be performed by a qualified installer in compliance with current regulations.
Make sure that the supply voltage and frequency are compatible with the electrical panel. The relative information is shown on the
motor rating plate and in the documents supplied with the panel. Provide suitable short circuit protection on the supply line.
Before proceeding, make sure that all the connections (even if they are potential-free) are voltage-free.
Unless otherwise specified in local bylaws, the supply line must be fitted with:
a short circuit protection device
a high sensitivity residual current circuit breaker (30mA) for additional protection from electrocution in case of inefficient
grounding.
a general switch with a contact aperture of at least 3 millimetres.
Ground the system in compliance with current regulations.
Single-phase version
Connect the electric pump to a supply line via a suitable electrical control panel containing the overload protection and the capacitor.
Refer to the wiring diagram on the outer casing of the motor and in figure 1 and the documentation supplied with the electrical
panel. (Only for motors 4GG series).
Refer to the motor rating plate for the capacity of the capacitor.
Install the electrical panel in a sheltered area.
Three-phase version
Connect the electric pump to a supply line via a suitable electrical control panel .
Install the electrical panel in a sheltered area.
Refer to the documentation supplied with the electrical panel.
For connections to any external control devices (e.g.: pressure switch, float) follow the instructions supplied with these devices.
Verify the correct execution of the junction,measuring the insulation resistance. For a new motor the correct measurement has to
be at least 200 Mohm

Maintenance, Service, Spare Parts
Before proceeding, always make sure the motor is disconnected from the supply line.
Maintenance operations may only be performed by expert and qualified people. Use suitable equipment and protective devices.
Observe all accident prevention regulations.
Do not attempt to disconnect the connector from the motor head cable.
This may only be done by authorised personnel.
Only use original spare parts to replace faulty components.
The motor does not require any scheduled routine maintenance.
Users wishing to prepare a maintenance schedule should bear in mind that maintenance frequencies depend on the conditions of use.
For any requirements, please contact our Sales and Service Department.
7.1
Spare Parts
Always specify the exact type of motor and code when requesting our Sales and Assistance Service for technical information or
spare parts.
Only use spare parts to replace faulty components. Unsuitable spare parts may cause the product to work incorrectly and cause
hazards for people and property.
