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.
6.6
Protections
6.6.1
Moving parts
In accordance with accident-prevention regulations, all moving parts (fans, couplings, etc.) must
be accurately protected with special devices (fan covers, coupling covers) 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.
6.6.2
Noise level
The noise levels of pumps with standard supply motors are indicated in table 6.6.2 on page 85.
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.
6.6.3
Hot and cold parts
As well as being at high temperature and high pressure, the
fluid in the system may also be in the form of steam!
DANGER OF BURNING.
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.

INSTALLATION
7.1
The electropump must be fitted in a well ventilated place, protected from unfavourable weather
conditions and with an environment temperature not exceeding 40°C.
Fig. B.
Electropumps with degree of protection IP55 may be installed in dusty and damp environments. If
installed in the open, generally it is not necessary to take any particular steps to protect them
against unfavourable weather conditions.
7.2
The buyer is fully responsible for preparing the foundation. Metal foundations must be painted to
avoid corrosion; they must be level an sufficiently rigid to withstand any stress due to short
circuits. Their dimensions must be calculated to avoid the occurrence of vibrations due to
resonance.
With concrete foundations, care must be taken to ensure that the concrete has set firmly and is
completely dry before placing the unit on it.
A firm anchoring of the feet of the pump assembly on the base helps absorb any vibrations created
by pump operation.
Fig. C.
7.3
Ensure that the metal pipes do not transmit excess force to the pump apertures, so as to avoid
causing deformations or breakages.
Fig. C.
Any expansion due to the heat of the pipes must be
compensated with suitable precautions to avoid weighing down on the pump. The flanges of the
pipes must be parallel to those of the pump.
7.4
To reduce noise to a minimum it is advisable to fit vibration-damping couplings on the intake and
delivery pipes and between the motor feet and the foundation.
