5. MANAGEMENT
5.1 Storage
All the pumps must be stored indoors, in a dry, vibration-
free and dust-free environment, possibly with constant
air humidity.
They are supplied in their original packaging and must
remain there until the time of installation. If this is not
possible, the intake and delivery aperture must be
accurately closed.
5.2 Transport
Avoid subjecting the electropumps to needless jolts or
collisions. The figures below indicate respectively how to
lift single electropumps – Fig. 1 – and twin versions
– Fig. 2 – during installation, after they have been
removed from the packaging .

5.3 Weights
The adhesive label on the package indicates the total
weight of the electropump.
6. WARNINGS
6.1 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).
6.2 Checking motor shaft rotation
Before installing the pump you must check that the
rotating parts turn freely. For this purpose, proceed as
follows on the pump concerned
: remove the fan cover
from its seat in the motor end cover, loosening the nuts.
Move the fan by hand to turn the motor shaft a few
times. If this is not possible, dismantle the pump body,
slackening the screws to check whether there are any
foreign bodies inside it. To disassemble, proceed in the
inverse order to assembly.
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.
6.3 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):

7. PROTECTIONS
7.1 Moving parts
In accordance with accident-prevention regulations, all
moving parts (fans, couplings, etc.) must be accurately
protected with special devices (fan covers,ecc.) before
operating the pump.
During pump operation, keep well away
from the moving parts (shaft, fan, etc.)
unless it is absolutely necessary, and only then
wearing suitable clothing as required by law, to avoid
being caught.
7.2 Noise level
The noise levels of pumps with standard supply motors are
indicated in table A on page 66.
Remember that, in cases where the LpA noise levels
exceed 85 Db(A), suitable HEARING PROTECTION must
be used in the place of installation, as required by the
regulations in force.
7.3 Hot and cold parts
DANGER OF BURNING
!!
As well as being at high temperature and
high pressure, the fluid in the system may
also be in the form of steam
!
It may be dangerous even to touch the pump or parts
of the system.
If the hot or cold parts are a source of danger, they must
be accurately protected to avoid contact with them
.
