ELECTRICAL CONNECTIONS
CHAPTER 4
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 Δ = 30 mA (DIN VDE 0100T739).
Verify that the voltage and frequency of the electropump shown on the nameplate correspond to those available
on the mains.
Connection, suction and delivery pipes should be connected with the utmost care. Make sure that all connections xed by
means of screws are sealed. Avoid applying excessive stress to tighten the screws of connections or of other components.
Use a Teon tape to completely seal all joints.

WARNING
WARNING
• Use a suction pump (2) with a diameter
equivalent to that of the suction mouth
of the electropump (1)
• If the height (HA) is over 4 meters use a
tube with a larger diameter
• The suction line should be perfectly
airtight. No elbows and/or slopes
should be present to prevent the
formation of air locks that could affect
the electropump eciency
• A foot valve (3) with lter (4) should be
tted at about half a metre below the
uid that has to be pumped (HI) on one
end of the line.
• Load losses can be reduced using
delivery piping with a diameter
equivalent or greater than the
electropump mouth (5).
• It is advisable to install a check
valve (6) directly on the delivery line
to prevent the electropump being
damaged by "water hammer"
• A cut-off valve (7) should also be
installed downstream from the
check valve, to facilitate servicing
operations.
• Piping should be tted 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 x the electropump to the
supporting base, connect the system
with a section of non exible 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
• Verify that the motor is properly
ventilated
• When connecting xed installations,
the plug must be clearly visible and
easily accessible
To use the pump in continuous mode for swimming pools, garden ponds and in similar installations, it is necessary to x the
electropump to a stable support. Mobile electropumps can be used for swimming pools, garden ponds or similar installations, only if no
peolpe is in contact with water or if the electric system has a safety cut-out switch.
The pump should be tted in a stable position in order to avoid falls and protect it from inundation. Contact a specialised electrician.
• BOOSTER SETS PENTAIR have a
built-in thermal protection switch
• The pump stops if an overload
condition occurs
OVERLOAD PROTECTION
• The motor restarts automatically after
it has cooled down
(see point 3 of the Troubleshooting
section for information on causes and
corrective actions)
• Supply cables and extensions should
have a section below that of H05 RN-F
• The plug and connections should be
protected by water splashes
