WARNING !!!
Use with diesel fuel
The pump must be installed under the water level, the liquid must drop into the pump body.
The pump should not run dry even for short periods of time; in order to do this check that the diesel fuel
is constantly being pumped during the entire working period of the pump.
As requested by the STANDARDISED REGULATIONS we advise the user to connect a recovery pipe
with the drain pipe in the lower part of the pump and let it drain into a collection tank, in order to prevent
diesel fuel leakage if the seal wears or breaks.
CH. 4 ELECTRICAL CONNECTION
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.
The following must be used as a conductor for the connection:
→
- outdoors cable H07RN-F
→
-
in inside areas cable H05RN-F or H07RN-F
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
CH. 5 STARTING THE UNIT (See Fig. 1)
Before starting the electropump fill the suction pipe and the electropump body by using the filling cap,
making sure that there are no leaks, close the cap and start the electropump. Check that it rotates
clockwise when looking at the electropump from the side of the motor fan. For the three phase electric
pumps it is possible to invert the rotation by changing the order of two phases, in order to do this
disconnect the pump from electric power supply.
If the electric pump does not work for long periods of time repeat the filling operations before starting
it up.

WARNING
DANGER
Electric shock risk
Ensure tension and frequency of electropump
(read plate) and power supply are same.
Installer must make sure that electric current
network has ground wire conforming to current
laws.
Make sure that electric current network is
provided with a high-sensitivity circuit breaker
,
=30 mA (DIN VDE 0100T739).
Use the electric pump for the type of uses listed on the
plate.
Do not let electric pump run dry, the hydraulic parts and
seal could be damaged and if it is used with diesel fuel,
the heat which develops could create a fire risk.
Do not run the electric pump with the delivery or the
interception valve closed, if it is used with diesel fuel, the
heat which develops could create a fire risk.
Before doing any operation, make sure machine is
disconnected from electric power supply.
