maintenance. This manual must be consulted by the installation personnel and by
all qualified personnel chosen by the installation manager to follow its operation.
Furthermore, the manual should always be at hand in the site where the pump is used.
1.1 Identification of the codified instructions in this manual
WARNING: General danger; failure to observe these safety instructions may
cause personal injury.
WARNING: Electrical hazard; failure to observe these instructions may cause
an electric shock with consequent risk of serious injury or death.
WARNING: Hot surface; failure to observe these safety instructions may cause
personal injury.
Risks deriving from failure to comply with safety regulations
Failure to comply with safety regulations may cause physical injury or material damage
as well as possible environmental contamination. Failure to comply with safety
regulations may lead to the complete loss of warranty rights.
To cite some examples, non-compliance with the said regulation may cause:
•
breakdown of the main functions of the machine or of the installation,
•
compromised maintenance operations,
•
physical damage of an electrical, mechanical nature.
1.1 General Information
This pump has been made according to the most recent and advanced techniques, in
full compliance with current standards and has been subject to strict quality control.
This manual will help you understand its function and learn its possible applications.
The user manual contains important recommendations necessary for correct and
economical operation. The recommendations should be observed in order to
guarantee the reliability, lifespan and to prevent accidents deriving from improper use.
The pump should not be used outside the limits described in the technical
specifications. It is necessary to observe the instructions regarding the nature, density,
temperature and volume of the pumped liquid, rotation speed and direction, pressure
and motor power as well as all the other instructions contained in this manual or the
documentation attached to the contract. The data plate indicates the model, the main
service specifications and the serial number. It is important to provide these indications
when requesting repairs or support and for requesting spare parts.
The manufacturer declines all liability for any damage that may, directly or
indirectly, be caused to people or things as a result of failure to observe all of
the provisions indicated in the instructions manual provided and in particular the
warnings concerning installation, use and maintenance of the electric pump or
in conditions other than those specified on the data plate. The warranty expires
definitively in the case of negligence or incorrect use of the product.

2 PRELIMINARY INSPECTION
2.1 Delivery and packing
The pumps are supplied in their original packing, in which they should remain until the
time of installation. Check that the packing is free from damage.
If the product appears to be damaged, inform the retailer immediately. Take care not
to bend the pump when the packing has been removed: this may cause misalignment
or damage to the pump itself. The pump should not be exposed to needless shocks
or impact.

2.2 Packaging contents
The packaging contains the product use and installation manual. In the case of an
electric pump, the packaging also contains the motor manual.
3 STORAGE AND HANDLING
3.1 Storage:
Storage temperature: from -5°C to +40°C
The pump and the motor must be kept in a dry, sheltered place, away from heat
sources, dirt and vibrations. If the pump has not been packed, it should be kept in
storage vertically, to prevent any misalignment.
3.2 Handling:
WARNING: Please observe the current accident prevention standards. Risk of
crushing. The pump may be heavy. Use suitable lifting methods and always
wear personal protection equipment.
Before handling the product, check its weight (see fig. 2) to identify suitable lifting
equipment.
WARNING: The eyebolts supplied with the motors should not be used to
handle the whole assembled electric pump (see fig.1.D).
For handling a pump with a motor of up to 4kW, use the belts wound around the pump
head, taking special care not to damage the side coupling covers in fig.1.A. For pumps
with a motor equal to or over 5.5 kW, use belts or chains attached to the lifting eyes on
the motor flange as shown in fig.1.B.
WARNING: There is a risk that the pump may overturn during handling; make
sure that the pump remains in a stable position during handling.
If there is no motor, use a belt wound around the pump head, paying particular
attention not to damage the side coupling covers (fig.1.E), or the lifting eyes on the
motor flange as shown in figure 1.F, if present. The eyebolts on the motor of the pumps
must be used exclusively to handle the motor alone (see fig. 1.C). Extract the pump
from the packaging and check that it is in good condition. Check also that the plate
data correspond to those required. For any defects, contact the supplier immediately,
reporting the nature of the same.
4 GENERAL DATA
