A cut-off valve (7) should also be installed downstream from the check valve, to facilitate servicing operations. Piping
should be fitted so that vibrations, when existing, tension and weight do not affect the pump. Piping should be routed
along the shortest and straighter track, avoiding an excessive number of bends. Verify that the motor is properly ventilated.
For permanent installations, it is advisable to fix the electropump to the supporting base, connect the system with a
section of non flexible pipe and insert a layer of rubber (or another anti-vibration material) between the supporting base
and the pump, in order to reduce vibrations.
The site of installation must be stable and dry to guarantee the stability of the pump.
ATTENTION!!!
Connection, suction and delivery pipes should be connected with the utmost care. Make sure that all connections
fixed by means of screws are sealed. Avoid applying excessive stress to tighten the screws of connections or of
other components. Use a Teflon tape to completely seal all joints.
To use the pump in continuous mode for swimming pools, garden ponds and in similar installations, it is necessary to
fix the electropump to a stable support.
Mobile electropumps can be used for swimming pools, garden ponds or similar installations, only if no people is contact
with water or if the electric system has a safety cut-out switch.
The pump should be fitted in a stable position in order to avoid falls and protect it from inundation.
Contact a specialised electrician.

Overload protection
The single phase motors are protected from overloads by a thermal device installed in the winding. The protection for
the three phase motor must be installed by the user.
Supply cables and extensions should have a section below that of H07 RN-F. The plug and connections should be
protected by water splashes.
For connecting single phase motors see Fig. 2
For connecting three phase motors see Fig. 3
For connecting double voltage single phase motors see Fig. 4

Verify that the voltage and frequency of the electropump shown on the nameplate
correspond to those available on the mains.
The installer must make sure that the electric system is grounded
in accordance with the law in force.
Make sure that the electric system has a high-sensitivity circuit
breaker
Use the electropump for the applications listed on the nameplate.
Do not operate the pump dry, since lack of water could cause it to
overheat. In this case, the water inside the system gets very hot, so
there is a risk of scalding. Take off the plug and let the system cool
down.
Do not run the electropump with a completely closed delivery.
