provided to keep the pump raised.
3.2. Transportable installation
To avoid early deterioration of the pump when used in
stagnant water or in rivers, mount on a flat surface rai-
sed from the ground so that sand or grit is not lifted.
When a plastic delivery pipe or flexible hose is
used, a rope is required for lowering, securing and
lifting the pump.
A safety rope or chain of non-perishable material
should always be used to secure the pump.
Never use the electric power cable
to suspend the pump.
In order to avoid the risk of mechanical or
electrical injury all portable pumps should
be securely isolated from electrical power
supply prior to their relocation.
Attach the power supply cable to the delivery pipe
or to the safety rope with cable clamps. The power
cable should not be taut: allow for a certain degree
of slackness to avoid the risk of strain caused by
expansion of the pipe during operation.

The coupling foot is fastened to the bottom of the
320 575
320 575 sump together with the delivery pipe; two guiding
tubes connect it to the anchoring bracket secured
to the edge of the sump cover.
The pump is lowered along the guiding tubes until
it reaches the exact coupling position; the seal
will be tight thanks to the weight of the pump.
This operation can be repeated any number of
times and it makes checking and inspection
operations easier; the pump is simply extracted
from the sump by means of a chain (even if the
system is flooded).
4. Electrical connection
Electrical connection must be carried out
only by a qualified electrician in accordance
with local regulations.
Follow all safety standards.
The unit must be always earthed, also with a
non-metallic delivery pipe.
Make sure the frequency and mains voltage corre-
spond with the name plate data.
For use in swimming pools (not when persons are
in the pool), garden ponds and similar places, a re-
sidual current device with I∆N not exceeding 30 mA
must be installed in the supply circuit.
Install a device for disconnection from the
mains (switch) with a contact separation of at least
3 mm on all poles.
When extension cables are used, make sure the
cable wires are of adequate size to avoid voltage
drops and that the connection stays dry.
4.1. Single-phase pumps
Supplied with incorporated capacitor and thermal
protector, with power cable type H07 RN8-F,
with plug and float switch.
Connect the plug to a socket with an earth lead.
