5. INSTALLATION
5.1 Preliminary inspections
ATTENTION The product may only be installed after a few simple inspections have been made.
lf oil leaks are noted after a long peri od of inactivity, check that the electric pump contains the right quantity
of oil. lf this is not the first installation, al so check that there are no impurities and/or water.
Always check that the pump-motor rotor is free to turn. Do this by slightly tilting the
pump to one side or hang it from a lifting means.
Now start the motor for a few seconds. Take great care, the kick-backs on start-up does
not damages to people.
5.2 Plant features
lf the electric pump must operate in sandy and/or muddy conditions, it should be set on a sol id base while
the suction mouth must be at such a distance from the deposited materiai as to prevent entrainment.
Check that the fluids pumped by electric pumps type F have no solids in suspension able to clog the pump.
lnstall a screen if necessary (check the free passage of the hydraulic part in the "Technical, operational
characteristics and fields of use" p:iragraph).
lf electric pump operati on is not checked by people, install automatic monitoring systems able to stop the
mach i ne when the operative conditions are no longer ensured (consult the"Unadvisable uses" paragraph).
5.3 Mechanical connections for fi
x
ed installation (series
VORX - PRNH)
Consult the"Dimensions and weights"chapter for fixed installation in a tank with support foot for automatic
coupling.
5.4 Electrical connections and information
The electric connection of free conductors must be carried out by qualified personnel
who strictly comply with all the current accident-prevention provisions in farce, the
instructions in this manual. AII yellow-green grounding conductors must be connected
to the grounding circuit of the system before the other conductors are connected. The
grounding conductors must be the last to be removed if the motor is disconnected.
Electrical equipment (when installed)
Checkthatthe electric contrai panel complies with the current accident-prevention standards
_&
and provisions. In particular, the protection degree should suit the piace of installation. lt
is advisable to install electrical equipment in dry, well ventilateci places.
ATTENTION Check that the thermic relay is set to a value that is no higher than the rated current
value on the data plate of the electric pump.
Power supply voltage
ATTENTION Check that the voltage and frequency values of the mains correspond to those on
the data plate of the electric pump. lf the voltage varies more than ± 5% of the rated
value, do not connect the unit but check the mains.
Rotation direction (for threephase motors only)
_&
Check the exact rotation direction by proceeding with the following operations:
- slightly tilt the pump to one side or hang it from a lifting means;
- start the motor for a few seconds, making sure that the kick-back does not become a danger hazard;
- if the kick-back has been anticlockwise, then the rotation direction is correct;
- if the rotation direction is wrong, disconnect the power supply and reconnect the electric pump to the
mains by switching two of the three phases with each other.
