5.2. Transport
Avoid subjecting the products to needless jolts or collisions.
To lift and transport the unit, use lifting equipment and the pallet supplied standard (if applicable).
Use suitable hemp or synthetic ropes only if the part can be easily slung, as indicated in fig.5.2. (A o B). If an eyebolt is
provided on the motor, it must not be used for lifting the whole assembly.
(A) - Transporting the pump (B) - Transporting the whole assembly
(fig.5.2.)
5.3. Dimensions and weights
The adhesive label on the package indicates the total weight of the electropump. The dimensions are given on page 119-123 /
124-130.
6. WARNINGS
6.1.
Skilled technical personnel
It is advisable that installation be carried out by skilled personnel in possession of the technical
qualifications required by the specific legislation in force.
The term skilled personnel means persons whose training, experience and instruction, as well as their
knowledge of the respective standards and requirements for accident prevention and working conditions, have
been approved by the person in charge of plant safety, authorizing them to perform all the necessary activities,
during which they are able to recognize and avoid all dangers. (Definition for technical personnel IEC 364).
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. (EN 60335-1 :02).
6.2. Safety
6.2.1.
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).
6.3. Checking pump/motor shaft rotation
Before installing the pump , it is advisable to check that the pump and/or motor shaft turns freely. To do this, in the case of
pumps supplied with a bare axis, check by turning the end of the pump shaft by hand. In the case of the electropump assembly
on a base, remove the coupling cover and check by turning the coupling by hand. When you have finished checking, return
the coupling cover to its original position.
Do not force the shaft or the fan of the motor (if supplied) with pliers or other tools
to try to free the pump, but look for the cause of the blockage.
6.4. New systems
Before running new systems the valves, pipes, tanks and couplings must be cleaned accurately. Often welding waste, flakes of
oxide or other impurities fall off after only a certain period of time. To prevent them from getting into the pump they must be
caught by suitable filters. The free surface of the filter must have a section at least 3 times larger than the section of the pipe
on which the filter is fitted, so as not to create excessive load losses. We recommend the use of TRUNCATED CONICAL
filters made of corrosion-resistant materials (SEE DIN 4181):
(Filter for intake pipe)
1) Filter body
2) Narrow mesh filter
3) Differential pressure gauge
4) Perforated sheet
5) Pump intake aperture
6.5. Responsibility
The Manufacturer does not vouch for correct operation of the pumps if they are tampered with or
modified, run outside the recommended work range or in contrast with the other instructions given in
this manual.
The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to
misprints or errors in copying. The company reserves the right to make any modifications to products
that it may consider necessary or useful, without affecting the essential characteristics.
