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, connecting them if possible to the
eyebolts provided.
In the case of coupled pumps, the eyebolts provided for lifting one part must not be used to lift the pump-
motor assembly.
5.3 Dimensions and weights
The adhesive label on the package indicates the total weight of the electropump. The dimensions are given
on page 110.
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 intended to be used by persons (including children) with reduced physical,
sensory or mental capacities, or who lack experience or knowledge, unless, through the
mediation of a person responsible for their safety, they have had the benefit of supervision or of
instructions on the use of the appliance. Children should be supervised to ensure that they do
not play with the appliance.
6.2 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).
6.3 Checking motor shaft rotation
Before installing the pump, it is advisable to check that the rotor shaft turns freely. To do this remove the fan
cover releasing it from the groove in the motor end cover, unscrewing the screws and the nuts if provided.
Working the fan by hand, turn the rotor shaft a few times. If this is not possible, dismantle the pump body,
slackening the screws to check for any foreign bodies inside it. To reassemble, proceed in inverse order.
Do not force the fan with pliers or other tools to try to free the pump as
this could cause deformation or breakage of the pump.
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).
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.
