Peripheral Submersible Pump
5. Use
The temperature of the liquid being pumped may not exceed 35° C. The pump may not be used for
swimming pools. The submersible pump you have purchased has been designed to pump clean
water or water that is chemically or mechanically non-aggressive with suspended solid particles ≤ 50 gr/m
in the event that the possibility remains of the presence of aggressive chemicals in the liquid to be pumped,
first test the resistance of the materials used in the construction of the product. The pump Is not suitable for
use with corrosive or abrasive liquids, fuels, or other chemical or explosive products.
6. Electrical connection
An electrical test prior to pump Installation conducted by a specialised technician should verify that
all the safety measures have been taken according to the regulations in force. Check to make sure that the
voltage and frequency correspond to the data on the rating plate. The electrical connection must be made to
a safe outlet installed according to regulations and which supplies a power supply voltage to the motor ± 6%
of the rated value. Use of the pump Is not permitted for swimming pools, basins of water and adjacent basins
unless a thermal protection device has been Installed. Consult a specialised technician. The electrical
connections must be protected from moisture. In the event of the risk of flooding, the connections must be
transferred to a protected area. Pumps for fountains and ponds must have a residual current device (RCD),
with current delivered no greater than 30 mA. The single-phase pump Is equipped with an Incorporated
thermal protection circuit that protects it against voltage overloads and any blockage. In the single-phase
version the condenser Is also Incorporated. When the pump halts due to overheating, it will start running
again after a cooling period of about 15 minutes (In the meantime, eliminate the cause of overheating).
7. Installation
For the maximum immersion depth, see the table of
technical characteristics. After Installing the pump in a well (pit),
carefully close the opening in an absolutely secure manner. The
user must Install an alarm or another pump for protection in
order to prevent damage due to flooding of the environment
caused by Interferences to the Installed electric pump. During
Installation, do not hold or lift the pump using the electrical
cable. Make sure that the well, basin or tank Is sufficiently large
to hold the pump and that It delivers a sufficient flow of water to
guarantee correct operation with a limited number of startups
per hour. In addition, before installing the pump, make sure that
the basin Is free of sand, debris or other foreign material that
could obstruct the hydraulic conduits of the pump.
For pumps without automatic float switch, it is necessary to
install a control system with minimum level probes that protects
the pump from dry operation. Attach rigid pipe or a rubber hose
to the outlet union of the pump. Make sure that the pipe/hose is
not bent and that the diameter Is equal to that of the pump outlet.
Put the pump in place.
8. Operation
The pump must absolutely never operate dry. Insert the plug into the socket.
