1. GENERAL
Read this documentation
carefully before installation.
Installation, electrical connection and commissioning
must be carried out by skilled personnel in compliance
with the general and local safety regulations in force in
the country of installation of the product. Failure to
comply with these instructions not only causes risk to
personal safety and damage to the equipment, but
invalidates every right to assistance under guarantee.
The appliance is not intendend for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsable for their safety. Children should be
supervised to ensure that they do not play with the
appliance.
Ensure that the product has not
suffered any damage during
transport or storage.
Check that the outer casing is
unbroken and in excellent conditions.
1.1 Safety
Use is allowed only if the electric system is in
possession of safety precautions in accordance with the
regulations in force in the country where the product is
installed (for Italy CEI 64/2).
1.2
Responsibility
The Manufacturer does not vouch for correct
operation of the machine or for any damage that it
may cause if it has been tampered with, modified
and/or run outside the recommended work range or
in contrast with other indications given in this
manual.
2. PUMPED
FLUIDS
The machine has been designed and built for pumping
water, free from explosive substances and solid
particles or fibres, with a density of 1000 kg/m³ and a
kinematic viscosity of 1 mm²/s, and chemically non-
aggressive liquids.
Small sand impurities of 40 gr./m³ - Ø 1 mm are
accepted.
3. TECHNICAL
DATA
3.1 Pump and motor group
The electric pump is a centrifugal multistage pump with
submersible motor and built-in non return valve,
designed to minimize friction losses.
The impellers are dinamically balanced and the shafts
are driven by co-axial bush bearings.
