SAFETY RULES
NOTE: Before installing and using the electric pump, carefully read the following instructions.
This manual contains basic instructions that must be observed when installing, using, servicing and
disposing of the appliance. Therefore, this instruction manual should be definitely referred to by all
qualified technical personnel in charge of installing, operating and servicing the appliance.
It should be properly kept and made available for reference on the installation site of the electric pump.
Identification of the coded instructions provided in this manual
The safety notes in this instruction manual are marked with a general hazard symbol. Failure
to comply with them may cause serious damage to health.
The safety notes marked with this symbol refer to electrical hazards.
Carefully read the instruction manual in all its parts before carrying out any operation on the
pump.
Risks associated with failure to comply with safety rules
Failure to comply with safety rules may cause physical and material damage, as well as environmental
pollution.
Non-observance of safety rules may totally invalidate your warranty.
To name a few examples, failure to comply with these rules can result in:
• failure of the main machine functions or of the installation,
• impairment of maintenance operations,
• bodily harm due to electrical, mechanical accidents.
Generalities
This appliance (pump or electric pump, depending on the model) was designed and manufactured
according to the most cutting-edge techniques, in full compliance with the regulations in force, and
subjected to strict quality control procedures.
This instruction manual will help you not only to understand how the appliance works, but also to get to
know its possible applications.
This user manual contains important recommendations that are necessary for the appliance to be
properly and economically operated. These recommendations must be observed in order to ensure
reliability and durability, as well as avoiding any risks of accidents resulting from improper use.
The appliance must be used for the intended applications and within the limits described in the following
paragraphs.
The activities related to handling, installing, using, servicing and disposing of the product pose risks for
human safety and for the environment that cannot be constructively eliminated.
The main residual risks are electrical (electrocution) and mechanical ones (squeezing or dragging by
moving parts, injuries caused by sharp edges, abrasions or crushing). All operations must be carried
out with the utmost attention only by expert, professional staff, equipped with appropriate personal
protective equipment and suitable tools, when the machine is disconnected. Failure to observe the
instructions provided in this manual and proper working practices will increase health risks.
The manufacturer accepts no responsibility in case of accident or damage caused by negligence,
improper use of the electric pump, or failure to follow the instructions described in this manual, or use in
conditions other than those permitted.
The appliance is delivered as standard with guards for protection against moving parts (e.g. coupling
shields and fan covers) or live parts (e.g. terminal block covers) during normal operation. Bare shaft
versions require coupling protectors that are not included in the product. To effectively protect these
machines, follow the instructions provided in the dedicated paragraph.
The user must not disassemble the electric pump completely or partially, nor make any
changes or tampering with the product. If removed during installation, guards must be refitted
immediately.
This equipment should not be used by people with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge of the product, as well as of the risks
associated with its use, unless they are closely supervised and instructed.
In any case, children and minors are not allowed to operate the equipment for its normal use
or play around it, even with no power supply. Children may not stand close to the pump if left
unattended.
Personal Protective Equipment (PPE)
During installation, routine and extraordinary maintenance, decommissioning and disposal, use the
personal protective equipment (PPE) specified below. Additional PPE may be necessary, depending on
the working conditions.
By properly using PPE, any residual health risks may be reduced.
Wear safety gloves
Protect your eyesight with safety glasses
Wear steel toe cap safety shoes, insulated from the ground
Wear a respirator if there is a risk of toxic, irritating or suffocating fumes
Suitable clothing
During maintenance operations and in any case when the machine is running in various
modes, including its normal operating mode, avoid any clothing or accessories that may get
entangled into the moving parts of the machine.
Declaration of conformity
The declaration of conformity, including the rules and regulations considered in the design phase, is
shown at the end of the manual.
Noise emission
Noise emission is mainly influenced by the size of the motor and pump.
For pumps supplied without motors, refer to the noise emission declared by the motor manufacturer and
consider a 3-5 dB increase.
For complete electric pumps, refer to
Tab. AT1
. The specified values refer to 50 Hz operation at a 1 m
distance from the machine. For operation at 60 Hz, increase values by about 3 dB.
Operators working long shifts in close proximity of the machine must protect themselves with hearing
aids that are appropriate to the sound pressure and exposure time.
1 PRELIMINARY INSPECTION
1.1 Delivery and packaging
The product is supplied in its original packaging, which includes this instruction manual, and must remain
packed until it is installed. The packed product must be stored away from atmospheric agents.
Remove the appliance from the packaging and check it for intactness. Also check whether the nameplate
details match the desired ones. To properly read the nameplate, refer to the instructions in this manual. In
case of any discrepancies, contact the supplier immediately, specifying the nature of the defects.
If in doubt about the machine safety or integrity, do not use it and contact a professional
service centre.
2 PRODUCT INFORMATION
The product model, main service specifications and serial number are shown on the nameplate. It is
important to provide these details when requesting interventions or support and spare parts.
The product model is identified by an alphanumeric code shown on the nameplate. The meaning of
the characters making up the code is explained in Fig. 1. The product can be identified via not only a
code but also a serial number (Fig. 2). This information can also be found on the label applied to this
instruction manual.
