1. WARNINGS
Before starting the pump, read this instruction booklet carefully.
The appliance may be used by children over 8 years old and by persons with reduced
physical, sensory or mental capacities, or who lack experience or knowledge, on
condition that they are under supervision or after they have received instructions
concerning the safe use of the appliance and the understanding of the dangers
involved. Children must not play with the appliance. Cleaning and maintenance
intended to be carried out by the user must not be performed by children without
supervision.
The pump must not be used to pump salt water or flammable, corrosive or
explosive liquids (e.g. petroleum oil, petrol, thinners), grease, oils or foodstuffs.
During operation the pump must be suitably immersed.
Provide protection against the lack of water to avoid the risk of running dry
(electronic control units ES..M – ES..T).
Before installation, clean all sand and other solid particles out of the borehole.
In no case should the power cable be used for carrying the pump or inserting it in
the borehole. Hang the pump on a rope to lower it into the borehole.
Choose the section of the power cable with correct dimensions, in relation to its
length, to avoid losses of voltage.
The connections of cables laid under water level must have a vulcanised join to
ensure that they are hermetically sealed.
Provide a good earth connection.
The mains voltage must correspond to the one on the motor data plate.
Make the connection to the mains by means of an omnipolar switch with contact
opening distance of at least 3 mm. Install a high-sensitivity differential switch (0.03 A)
as additional protection.
Single-phase motors must be connected to the mains by means of the
Control Box 4” – Control Sub which provides overload protection, protecting the
motor against current overloads. Three-phase motors must be protected by special
motor protection devices.
